Cinchona Alkaloids
Alkaloids extracted from various species of Cinchona.
Cinchona
A genus of rubiaceous South American trees that yields the toxic CINCHONA ALKALOIDS from their bark; QUININE; QUINIDINE; chinconine, cinchonidine and others are used to treat MALARIA and CARDIAC ARRHYTHMIAS.
Chloroacetates
ACETIC ACID or acetic acid esters substituted with one or more CHLORINE atoms.
Quinidine
An optical isomer of quinine, extracted from the bark of the CHINCHONA tree and similar plant species. This alkaloid dampens the excitability of cardiac and skeletal muscles by blocking sodium and potassium currents across cellular membranes. It prolongs cellular ACTION POTENTIALS, and decreases automaticity. Quinidine also blocks muscarinic and alpha-adrenergic neurotransmission.
Alkaloids
Organic nitrogenous bases. Many alkaloids of medical importance occur in the animal and vegetable kingdoms, and some have been synthesized. (Grant & Hackh's Chemical Dictionary, 5th ed)
Quinine
An alkaloid derived from the bark of the cinchona tree. It is used as an antimalarial drug, and is the active ingredient in extracts of the cinchona that have been used for that purpose since before 1633. Quinine is also a mild antipyretic and analgesic and has been used in common cold preparations for that purpose. It was used commonly and as a bitter and flavoring agent, and is still useful for the treatment of babesiosis. Quinine is also useful in some muscular disorders, especially nocturnal leg cramps and myotonia congenita, because of its direct effects on muscle membrane and sodium channels. The mechanisms of its antimalarial effects are not well understood.
Stereoisomerism
The phenomenon whereby compounds whose molecules have the same number and kind of atoms and the same atomic arrangement, but differ in their spatial relationships. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 5th ed)
Catalysis
The facilitation of a chemical reaction by material (catalyst) that is not consumed by the reaction.
Quinuclidines
Ketones
Rubiaceae
The Madder plant family of the order Rubiales, subclass Asteridae, class Magnoliopsida includes important medicinal plants that provide QUININE; IPECAC; and COFFEE. They have opposite leaves and interpetiolar stipules.
Biological Products
Complex pharmaceutical substances, preparations, or matter derived from organisms usually obtained by biological methods or assay.

Plant Bark
The outer layer of the woody parts of plants.
Phylogeny
The relationships of groups of organisms as reflected by their genetic makeup.
Capillary Electrochromatography
A separation technique which combines LIQUID CHROMATOGRAPHY and CAPILLARY ELECTROPHORESIS.
Silica Gel
A non-crystalline form of silicon oxide that has absorptive properties. It is commonly used as a desiccating agent and as a stationary phase for CHROMATOGRAPHY. The fully hydrated form of silica gel has distinct properties and is referred to as SILICIC ACID.
Phenylcarbamates
Phenyl esters of carbamic acid or of N-substituted carbamic acids. Structures are similar to PHENYLUREA COMPOUNDS with a carbamate in place of the urea.
Alkadienes
Acyclic branched or unbranched hydrocarbons having two carbon-carbon double bonds.
Sesquiterpenes, Guaiane
SESQUITERPENES cyclized into two adjoining rings, one being 7-carbons and the other is 5-carbons.
Cyclization
Changing an open-chain hydrocarbon to a closed ring. (McGraw-Hill Dictionary of Scientific and Technical Terms, 5th ed)
Phosphines
Inorganic or organic compounds derived from phosphine (PH3) by the replacement of H atoms. (From Grant & Hackh's Chemical Dictionary, 5th ed)
Tropical Medicine
The branch of medicine concerned with diseases, mainly of parasitic origin, common in tropical and subtropical regions.
Malaysia
A parliamentary democracy with a constitutional monarch in southeast Asia, consisting of 11 states (West Malaysia) on the Malay Peninsula and two states (East Malaysia) on the island of BORNEO. It is also called the Federation of Malaysia. Its capital is Kuala Lumpur. Before 1963 it was the Union of Malaya. It reorganized in 1948 as the Federation of Malaya, becoming independent from British Malaya in 1957 and becoming Malaysia in 1963 as a federation of Malaya, Sabah, Sarawak, and Singapore (which seceded in 1965). The form Malay- probably derives from the Tamil malay, mountain, with reference to its geography.

Role of the choline exchanger in Na(+)-independent Mg(2+) efflux from rat erythrocytes. (1/34)

Two types of Na(+)-independent Mg(2+) efflux exist in erythrocytes: (1) Mg(2+) efflux in sucrose medium and (2) Mg(2+) efflux in high Cl(-) media such as KCl-, LiCl- or choline Cl-medium. The mechanism of Na(+)-independent Mg(2+) efflux in choline Cl medium was investigated in this study. Non-selective transport by the following transport mechanisms has been excluded: K(+),Cl(-)- and Na(+),K(+),Cl(-)-symport, Na(+)/H(+)-, Na(+)/Mg(2+)-, Na(+)/Ca(2+)- and K(+)(Na(+))/H(+) antiport, Ca(2+)-activated K(+) channel and Mg(2+) leak flux. We suggest that, in choline Cl medium, Na(+)-independent Mg(2+) efflux can be performed by non-selective transport via the choline exchanger. This was supported through inhibition of Mg(2+) efflux by hemicholinum-3 (HC-3), dodecyltrimethylammonium bromide (DoTMA) and cinchona alkaloids, which are inhibitors of the choline exchanger. Increasing concentrations of HC-3 inhibited the efflux of choline and efflux of Mg(2+) to the same degree. The K(d) value for inhibition of [(14)C]choline efflux and for inhibition of Mg(2+) efflux by HC-3 were the same within the experimental error. Inhibition of choline efflux and of Mg(2+) efflux in choline medium occurred as follows: quinine>cinchonine>HC-3>DoTMA. Mg(2+) efflux was reduced to the same degree by these inhibitors as was the [(14)C]choline efflux.  (+info)

Transformation of Cinchona alkaloids into 1-N-oxide derivatives by endophytic Xylaria sp isolated from Cinchona pubescens. (2/34)

The microbial transformation of four Cinchona alkaloids (quinine, quinidine, cinchonidine, and cinchonine) by endophytic fungi isolated from Cinchona pubescens was investigated. The endophytic filamentous fungus Xylaria sp. was found to transform the Cinchona alkaloids into their 1-N-oxide derivatives.  (+info)

Highly stereoselective, uniformly sized molecularly imprinted polymers for cinchona alkaloids in hydro-organic mobile phases. (3/34)

Highly stereoselective, uniformly sized molecularly imprinted polymers (MIPs) for cinchona alkaloids, cinchonine (CN) and cinchonidine (CD), were prepared using methacrylic acid (MAA) as a functional monomer and ethylene glycol dimethacrylate (EDMA) as a cross-linker. The MIPs were evaluated using a mixture of phosphate buffer and acetonitrile as the mobile phase. The CN- and CD-imprinted MAA-co-EDMA polymers can recognize the respective template molecule more than the other diastereomer, and afford an excellent diastereomer separation of CN and CD. In addition, the MIPs gave diastereomer separations of structurally related compounds, quinidine and quinine. The retentive and stereoselective properties of those compounds on the MIPs suggest that electrostatic and hydrophobic interactions can work to recognize these compounds. Furthermore, thermodynamic studies reveal that the entropy-driven effect is significant at mobile-phase pH 5.4, while the enthalpy-driven interactions seem to be dominant at mobile-phase pH 9.6.  (+info)

The relationship of physico-chemical properties and structure to the differential antiplasmodial activity of the cinchona alkaloids. (4/34)

BACKGROUND: The 8-amino and 9-hydroxy substituents of antimalarial cinchona alkaloids have the erythro orientation while their inactive 9-epimers are threo. From the X-ray structures a 90 degrees difference in torsion angle between the N1-H1 and C9-O12 bonds in the two series is believed to be important. In order to kill the malaria parasite, alkaloids must cross the erythrocyte and parasite membranes to accumulate in the acid digestive vacuole where they prevent detoxication of haematin produced during haemoglobin breakdown. METHODS: Ionization constants, octanol/water distribution and haematin interaction are examined for eight alkaloids to explain the influence of small structural differences on activity. RESULTS: Erythro isomers have a high distribution ratio of 55:1 from plasma to the erythrocyte membrane, while for the more basic threo epimers this is only 4.5:1. This gives an increased transfer rate of the erythro drugs into the erythrocyte and thence into the parasite vacuole where their favourable conformation allows interaction with haematin, inhibiting its dimerization strongly (90 +/- 7%) and thereby killing the parasite. The threo compounds not only enter more slowly but are then severely restricted from binding to haematin by the gauche alignment of their N1-H1 and C9-O12 bonds. Confirmatory molecular models allowed measurement of angles and bond lengths and computation of the electronic spectrum of a quinine-haematin complex. CONCLUSION: Differences in the antiplasmodial activity of the erythro and threo cinchona alkaloids may therefore be attributed to the cumulative effects of lipid/aqueous distribution ratio and drug-haematin interaction. Possible insights into the mechanism of chloroquine-resistance are discussed.  (+info)

Stereochemical evaluation of the relative activities of the cinchona alkaloids against Plasmodium falciparum. (5/34)

Quinine and quinidine were over 100 times more active than 9-epiquinine and 9-epiquinidine against chloroquine-sensitive Plasmodium falciparum and over 10 times more active against chloroquine-resistant P. falciparum. Since the only structural difference between quinine, quinidine, 9-epiquinine, and 9-epiquinidine is their three-dimensional configuration, the three-dimensional structures of these four alkaloids were examined in order to explain the large difference in relative activities between the 9-epi alkaloids and quinine and quinidine. The crystal structure of 9-epiquinidine hydrochloride monohydrate was determined by X-ray diffraction and was compared with the crystal structures of quinine, quinidine sulfate dihydrate, and 9-epiquinine hydrochloride dihydrate. The crystallographic parameters for 9-epiquinidine hydrochloride monohydrate were as follows: chemical formula, C20H25N2O2+.Cl-.H2O; M(r), 378.9; symmetry of unit cell, orthorhombic; space group, P2(1)2(1)2(1); parameters of unit cell, a was 7.042 +/- 0.001 A (1 A = 0.1 nm), b was 9.082 +/- 0.001 A, c was 31.007 +/- 0.005 A; the volume of unit cell was 1,983.1 +/- 0.6 A3; number of molecules per unit cell was 4; the calculated density was 1.27 g cm-3; the source of radiation was Cu K alpha (lambda = 1.54178 A); mu (absorption coefficient) was 18.82 cm-1; F(000) (sum of atomic scattering factors at zero scattering angle) was 808; room temperature was used; final R (residual index) was 5.72% for 1,501 reflections with magnitude of F(o) greater than 3 sigma (F). The intramolecular distance from N-1 to O-12 in 9-epiquinidine and 9-epiquinine, although shorter than the corresponding distance in quinine and quinidine, was similar to those of other active amino alcohol antimalarial agents. In all four alkaloids, both the hydroxyl and amine groups formed intermolecular hydrogen bonds, showing the potential for forming hydrogen bonds with cellular constituents. However, the positioning of the N+-1--H-N1 and O-12--H-O12 groups relative to each other was quite different in the 9-epi alkaloids versus quinidine. This difference in positioning may determine the relative strengths, of the formation of hydrogen bonds with cellular constituents important to antimalarial activity and, therefore, may determine the relative strength of antimalarial activity.  (+info)

Dose-dependent resorption of quinine after intrarectal administration to children with moderate Plasmodium falciparum malaria. (6/34)

The pharmacokinetics of increasing doses of an intrarectal Cinchona alkaloid combination containing 96.1% quinine, 2.5% quinidine, 0.68% cinchonine, and 0.67% cinchonidine (Quinimax) was compared to that of parenteral regimens in 60 children with moderate malaria. Quinine exhibited a nonlinear pharmacokinetics, suggesting a saturation of rectal resorption. When early rejections appeared, blood quinine concentrations decreased by 30 to 50% and were restored by an immediate half-dose administration of the drug. Rectal administration of doses of 16 or 20 mg/kg of body weight led to concentration-time profiles in blood similar to those of parenteral regimens and could be an early treatment of childhood malaria.  (+info)

Carbon nanotubes as adsorbent of solid-phase extraction and matrix for laser desorption/ionization mass spectrometry. (7/34)

A method with carbon nanotubes functioning both as the adsorbent of solid-phase extraction (SPE) and the matrix for matrix assisted laser desorption/ionization mass spectrometry (MALDI-MS) to analyze small molecules in solution has been developed. In this method, 10 microL suspensions of carbon nanotubes in 50% (vol/vol) methanol were added to the sample solution to extract analytes onto surface of carbon nanotubes because of their dramatic hydrophobicity. Carbon nanotubes in solution are deposited onto the bottom of tube with centrifugation. After removing the supernatant fluid, carbon nanotubes are suspended again with dispersant and pipetted directly onto the sample target of the MALDI-MS to perform a mass spectrometric analysis. It was demonstrated by analysis of a variety of small molecules that the resolution of peaks and the efficiency of desorption/ionization on the carbon nanotubes are better than those on the activated carbon. It is found that with the addition of glycerol and sucrose to the dispersant, the intensity, the ratio of signal to noise (S/N), and the resolution of peaks for analytes by mass spectrometry increased greatly. Compared with the previously reported method by depositing sample solution onto thin layer of carbon nanotubes, it is observed that the detection limit for analytes can be enhanced about 10 to 100 times due to solid-phase extraction of analytes in solution by carbon nanotubes. An acceptable result of simultaneously quantitative analysis of three analytes in solution has been achieved. The application in determining drugs spiked into urine has also been realized.  (+info)

Cinchonine, a potent efflux inhibitor to circumvent anthracycline resistance in vivo. (8/34)

Circumvention of multidrug resistance is a new field of investigation in cancer chemotherapy, and safe and potent multidrug resistance inhibitors are needed for clinical use. We investigated several analogues of quinine for their ability to increase anthracycline uptake in resistant cancer cells. Cinchonine was the most potent inhibitor of anthracycline resistance in vitro, and its activity was little altered by serum proteins. Serum from rats treated with i.v. cinchonine produced greater uptake of doxorubicin in cancer cells (DHD/K12/PROb rat colon cells and K562/ADM human leukemic cells) than did serum from quinine-treated rats (ex vivo assay). Cinchonine was more effective than quinine in reducing tumor mass and increasing the survival of rats inoculated i.p. with DHD/K12/PROb cells and treated i.p. with deoxydoxorubicin. Moreover, the acute toxicity of cinchonine in rats and mice was lower than that of other quinine-related compounds. The lower toxicity and greater potentiation of in vivo anthracycline activity produced by cinchonine are favorable characteristics for its use as an anti-multidrug resistance agent in future clinical trials.  (+info)

In an attempt to further improve catalyst enantioselectivities, Jew and Park linked two cinchona alkaloid moieties via spacer units. With such a dimeric cinchona alkaloid (06542), enantioselectivity for the above mentioned glycine imine alkylation was optimized to 97-99% ee.1. Nucleophilic catalysts have had a wide-ranging role in the development of new synthetic methods. In particular, the cinchona alkaloids catalyze many useful processes with high enantioselectivities. Cinchona alkaloids can be used as bases to deprotonate substrates with relatively acidic protons forming a contact ion pair between the resulting anion and protonated amine. This interaction leads to a chiral environment around the anion and permits enantioselective reactions with electrophiles.. Important in many of these processes is the ability to control the formation of quaternary asymmetric centers with high enantiomeric excesses.

Though the Peruvian bark was introduced into Europe so early as 1640, it was not until the year 1737 that the plant producing it was known to naturalists. In that year La Condamine, on a journey from Quito to Lima, through the province of Loxa, had an opportunity of examining the tree, of which, upon his return, he published a very complete description, with plate, under the name Quinquina, stating that three species were recognized. (Mem. Ac., Paris, 1738, p. 226.) Four years later, Linne proposed a new name, Cinchona, in honor of the Countess of Chinchon, who first made the bark known in Europe. Linne recognized but one species, which he called C. officinalis, and this continued for a long time to be recognized by the Pharmacopoeias as the only source of the Peruvian bark of commerce. But a vast number of plants belonging to the Linnaean genus Cinchona were in the course of time discovered; and the list became at length so unwieldy and heterogeneous that botanists were compelled to distribute ...

Considerable inter- and intraspecific variation with respect to the quantity and composition of plant natural products exists. The processes that drive this variation remain largely unknown. Understanding which factors determine chemical diversity has the potential to shed light on plant defenses against herbivores and diseases and accelerate drug discovery. For centuries, Cinchona alkaloids were the primary treatment of malaria. Using Cinchona calisaya as a model, we generated genetic profiles of leaf samples from four plastid (trnL-F, matK, rps16 and ndhF) and one nuclear (ITS) DNA regions from twenty-two Cinchona calisaya stands sampled in the Yungas region of La Paz (Bolivia). Climatic and soil parameters were characterized and bark samples were analyzed for content of the four major alkaloids using HPLC-UV to explore the utility of evolutionary history (phylogeny) in determining variation within species of these compounds under natural conditions. A significant phylogenetic signal was found for the

Formerly, the bark in different forms was used as a drug, but later natural harvesting formed the base of the production of cinchona alkaloids. This industry was carried on principally in Germany, and the Dutch and English cinchona plantations in Java, Ceylon and India were the chief sources whence the raw material was supplied. Its main active principle, quinine is now chemically synthesized. In 1823, Dr. John Sappington of Philadelphia acquired several pounds of quinine and issued Dr. Sappingtons Fever Pills. He persuaded ministers in the Mississippi River Valley to ring the church bells every evening to alert people to take the pills, and through that enterprise, Sappington became a very wealthy man.. By the mid-19th century the Dutch and English began claiming that the South American supply of cinchona was threatened by the non-sustainable cutting practices of the indigenous harvesters.

Quinine - WikipediaQuinine - Wikipedia
Quinine was also the first drug used for treatment of malaria.[40] Quinine was used as a muscle relaxant by the Quechua, who are indigenous to Peru, Bolivia and Ecuador, to halt shivering due to low temperatures.[41] The Quechuas would mix the ground bark of cinchona trees with sweetened water to offset the barks bitter taste, thus producing tonic water.[citation needed] The Jesuits were the first to bring cinchona to Europe. The Spanish were aware of the medicinal properties of cinchona bark by the 1570s or earlier: Nicolás Monardes (1571) and Juan Fragoso (1572) both described a tree that was subsequently identified as the cinchona tree and whose bark was used to produce a drink to treat diarrhea.[42] Quinine has been used in unextracted form by Europeans since at least the early 17th century. It was first used to treat malaria in Rome in 1631. During the 17th century, malaria was endemic to the swamps and marshes surrounding the city of Rome. Malaria was responsible for the deaths of ...

Chloroquine was developed by German chemists as a direct descendant of quinine, which is derived from the bark of the Amazonian cinchona tree. Spanish conquistadors learned from native people to use cinchona bark to combat malaria. Mixed with gin, favored by the British, it became a West Indian afternoon staple - gin and tonic.. During World War II, American soldiers and marines were fed another cinchona offspring, atabrine, which made them sick from liver damage and turned some GIS blue.. Vanity Fair magazine claims in its current issue that some of Trumps business cronies had a plan to flood the greater New York City area with the two chloroquines after the president promoted its anti-COVID properties. This would not be surprising, given Trumps use of his hotel and golf clubs for official business..

Vladimir Prelog - WikipediaVladimir Prelog - Wikipedia
Prelogs main interest was focused on alkaloids. He found an ideal topic in the elucidation of the structure of solanine; he continued his work on Cinchona alkaloids and started to investigate strychnine. He showed that Robert Robinsons formula for strychnine was not correct. Although the formula he proposed was also not the right one, the discovery increased his international prestige. Later he worked on elucidating the structures of aromatic Erythrina alkaloids with Derek Barton, Oskar Jeger and Robert Burns Woodward.[12] At mid-century, the instrumental revolution necessitated a new approach to structural elucidation. Purely chemical methods had become outdated and had lost some of their intellectual appeal. Recognizing the growing importance of microbial metabolites, Prelog started working on these compounds, which possess unusual structures and interesting biological properties. It led him into antibiotics, and he subsequently elucidated the structures of such compounds as nonactin, ...

Quite. Homeopaths select these remedies according to a principle known as the Law of Similars, or Like cures like. In 1790, the German physician Samuel Hahnemann noticed that cinchona bark, which contains quinine and had long been used as a malaria remedy, actually produced some of the symptoms of malaria when taken by a healthy person (namely himself). Unfortunately for homeopaths, it may be that Hahnemanns reaction to the cinchona was in fact simply the result of an undiagnosed allergy. Nevertheless, it led him to wonder if a general principle of similarity could be used to discover new remedies, and to classify the chaotic muddle of herbal and mineral preparations that constituted the materia medica of the day. He therefore embarked on a series of experiments upon himself and others, to test for the pathological effects of various substances, including mercury, belladonna, tobacco and nux vomica. Family, friends, students and colleagues submitted themselves to these provings, and by ...

This book is a monograph on the treatment of malaria. It has nine chapters and ninety-one pages. Each chapter treats of a distinct phase of the subject and a perusal of the chapter titles given below will give a good idea of the scope of the work. The first impression gained in reading this book is that the author is giving the reader the results of his own personal experience and that although references are frequent the subject matter is true first hand knowledge. Chapter I: Cinchona Febrifuge. This is evidently a proprietary article, considerably used throughout the British dependencies and without legally defined composition.

1857 On this day in Fettercairn Scotland, the amateur botanist David Prain was born.. He would ultimately become the Director of the Royal Botanic Gardens of Calcutta and Kew.. In 1887, David was sent to Calcutta to be the curator of the herbarium. While he was there, he researched Indian Hemp along with crops like Wheat, Mustard, Pulses, and Indigo. But, Davids most crucial work involved Cinchona plantations. The bark of Cinchona trees contains quinine, which is used to treat malaria. In Davids obituary, it said that he set up a system with the local post offices to send quinine to every Indian village and undoubtedly saved countless lives.. After David returned to England, he became the director at Kew. During his tenure, David implemented many notable changes. David oversaw the effort to have the medicinal garden installed at Cambridge Cottage, and he acquired the Japanese gateway for the 1910 Japan-British exhibition.

Quinine was discovered as a cure for Malaria in 1638 when the wife of the Spanish Viceroy in Peru, the Countess of Cinchona, had fallen violently ill with the disease. Her husband begged the local Incas for an antidote. The Incas instructed her to drink a potion containing the ground bark of the native Quinquina tree, which grew on the slopes of the Andes. The potion worked and she quickly recovered. In her honour, the Spanish renamed the Peruvian tree the Cinchona tree ...

The Complex History Behind Summers Best Cocktail - THE LORES.The Complex History Behind Summers Best Cocktail - THE LORES.
The mosquito-borne disease was a prevalent problem among the growing British population of India, the country then known as the crown jewel of the British Empire. During the 1800s, South America was exporting massive amounts of cinchona bark to Europe for malarial treatment, and it was invaluable to English colonial efforts. Like a lot of medicine, quinine didnt taste great. British soldiers made it more palatable by mixing it with sugar and water. Tonic water (or Indian tonic water as it was called) was still a little unpleasant by itself, until an enterprising Brit mixed it with the standard gin ration soldiers received. Interestingly, all of the basic ingredients of the G+T had some root in medicine. Jenever was originally brewed for treatment of various ailments, while limes were used by the British to treat scurvy. Today there are far more effective malaria treatments than quinine, and scurvy isnt much of a concern anymore, so telling your boss youre day drinking at work for health ...

VISIT any health shop and you are likely to see them: packages of homeopathic remedies claiming to cure whatever ails you, from coughs and fever to insomnia and asthma. Flip the package of medicine, however, and you may be confused by the listed ingredients. Some claim to contain crushed bees, stinging nettles and even arsenic, as well as sugars such as lactose and sucrose. Americans alone spend some $3 billion a year on homeopathic medicines. What are they thinking?. The history of homeopathy - literally, similar suffering - dates back to the late 18th century. Samuel Hahnemann, a German doctor, was unimpressed by contemporary medicine, with good reason. Doctors used leeches to let blood and hot plasters to bring on blisters, which were then drained. In 1790, Hahnemann developed a fever that transformed his career. After swallowing powder from the bark of a cinchona tree, he saw his body temperature rise. Cinchona bark contains quinine, which was already known to treat malaria. Hahnemann ...

Cyclamen which is similar in many respects, differs from Pulsatilla in dreading the fresh air.

Special symptoms are heaviness of the head, loss of sight, fainting and ringing in the ears, sour belching, poor digestion and bloated abdomen. The patient is sensitive to draughts of air and yet wants to be fanned. Natrum muriaticum is also a remedy for ansemic and debilitated conditions due to loss of fluids, especially in women who suffer from menstrual disorders and in chronic cases with a dead, dirty-looking skin.

Good Afternoon -. I am not a doctor so please consider that. I will tell you what was recommended to us in the UN as a malarial prevention plan, and what was considered safe out of medical expert advice.. Please remember there are many types of chloroquine - that is quinine-based medicines - and there is also cinchona bark -one original source of quinine used for centuries by peoples living in malarial zones.. I speak here of HCQ hydroxychloroquine sulphate. This was developed to be softer on the liver mainly for people to use for Lupus and for Arthritis . Prior to that chloroquine phosphate was popular.. To prevent malaria and what I am now on as a prevention for COVID is 400 mg of HCQ per WEEK - so only once per week. I would consider myself of low exposure so this dose is maybe not right for a doctor or other front liner…I am 61 - ex light smoker..

The original recipe for this libation was created by Gaetan Picon around 1837. Picon was born in Genoa, Italy and moved to France as a young man. He apprenticed in a number of distilleries in southern France. His interest in chemistry and the botanical properties of plants came in handy while serving in the French foreign legion in Algiers, Algeria, when he and a number of other soldiers were stricken with malaria. He concocted what he called tisane or tea. The recipe was a mixture he remembered his grandmother preparing for him when he suffered from malaria as a young man. It was, in fact, a neutral alcohol infused with dried orange peel and steeped, to this he added dried gentian root, cinchona bark (quinine), sugar syrup, spices, herbs and caramel.

Bartenders find complexity in new aperitifs - SFGateBartenders find complexity in new aperitifs - SFGate
Smith says more bartenders are satisfying this desire by dipping into the little-known well of French aperitif wines known as quinquinas and their Italian counterparts, chinati. While vermouths subtle bitterness traditionally comes from wormwood, quinquinas and chinati acquire their bite from quinine, a substance found in cinchona bark that is also used to flavor tonic water. Along with the distinctive flavor, these wines share with tonic water a history as a pharmaceutical. In 1846, while vying for a government reward for creating a palatable quinine-delivery vehicle, Parisian chemist Joseph Dubonnet introduced the first successful quinquina, flavored with chamomile, green coffee beans, cinnamon and more. When combined with other ingredients in a base of mistelle - partially fermented grape juice mixed with higher-proof alcohol - its character is simultaneously juicy and bone dry. While Bonal is a new entry to the U.S. market, Cocchi Americano has been sporadically available in the Bay Area for

Quinine - Simple English Wikipedia, the free encyclopediaQuinine - Simple English Wikipedia, the free encyclopedia
Quinine [1] is an alkaloid which can reduce fever, work against malaria, pain and swelling. The bark of the Cinchona family of trees contains quinine. Quinine can be made artificially, but this is more expensive than extracting it from the bark of the tree. This tree is found in the Andes, South America, Indonesia, and Congo. Quinine was the first treatment for malaria, known from 1631 in Europe,[2][3] and probably much earlier to the native peoples of South America. Even today, quinine is used to treat certain forms of malaria, when other drugs fail or are unavailable. In that way, quinine is currently one of the best treatments for malaria tropica, which is caused by plasmodium falciparum. For the other forms of malaria, quinine is no longer used, as other drugs have replaced it. ...

In case you or your loved one is afflicted with malaria or certain other diseases or afflictions then you might have to start using quinine tablets for treatment of malaria or for those specific medical conditions. Quinine is in the forefront for fighting malaria in several countries although it has lost favor with the FDA in America.. Quinine is extracted from the bark of the cinchona tree and has been used since well over three centuries to fight malaria. Quinine is known to kill the P.Falciparum parasite that is responsible for spreading malaria into the body and causing death in case of inadequate treatment. There are different methods of administering quinine to patients such as by intravenous drips or injections or in the form of tablets. While quinine is extremely bitter and can easily induce vomiting if administered in its natural form, quinine tablets that contain quinine sulfate with other ingredients to make it palatable can be given to both adults and children.

If you need to go in for medical treatment that involves the use of quinine or wish to consume products that contain quinine then you should know all about what is quinine. It is certainly important to understand more about this potent drug as well as its side-effects.. Quinine is extracted from the bark of the cinchona tree. The malaria-fighting abilities of this bitter-tasting drug were discovered by the Quechua Indians several centuries ago and its popularity soon reached the shores of Europe, USA, and the rest of the world where malaria was rampant. While quinine was primarily used to treat malaria during the seventeenth century, it was also used to treat arthritis, lupus, as well as leg cramps since it also acted as a muscle relaxant while possessing anti-inflammatory properties too. Quinine was administered orally in the form of quinine sulfate tablets and also delivered in intravenous form to patients including children that had contacted malaria. Adults usually had to consume around 600 ...

Therapeutic effects of quinine in a mouse model of atopic dermatitisTherapeutic effects of quinine in a mouse model of atopic dermatitis
Quinine, an alkaloid derived from the bark of cinchona in the Andean forests, was the first effective treatment for malaria (32). Studies have reported that the TAS2R agonist can inhibit IgE secretion in a mouse model of asthma, thus relieving the clinical symptoms (12,13). Therefore, the present study aimed to evaluate the therapeutic effects of quinine on AD-like mice. The results demonstrated that quinine treatment effectively attenuated AD-like symptoms in mice, reducing the dermatitis severity score, serum IgE levels and the infiltration of inflammatory cells, as well as alleviating the pathological damage, inhibiting the expression of genes related to the NF-κB signaling pathway, reducing the inflammatory response and promoting the expression of the skin-protective protein FLG. It was also found that quinine reduced cytokine levels in the AD-like mice. These results suggested that the topical application of quinine may provide a novel therapeutic regimen for the treatment AD, as well as ...

Antimalarial drugs were first discovered in the seventeenth century [1], two and one-half centuries before the causative agent of malaria was identified. As no other drug before it, quinine, the first antimalarial agent derived from the cinchona tree, helped to shape todays world by enabling explorers and colonists from Europe to survive in tropical countries and to build their colonial empires despite lethal tropical malaria. When physicians were asked to choose the ten most important drugs being used in medicine in 1945, quinine and quinacrine were preceded only by penicillin, sulfonamides and blood derivatives [2]. The antimalarial activity of quinoline antimalarial drugs can be attributed to the interfering with hemoglobin digestion in the blood stages of the malaria parasites life cycle. The parasite degrades the host hemoglobin, in an acidic food vacuole, to generate amino acids for its own protein synthesis, and producing free heme and reactive oxygen species as toxic by-products. The ...

Fever Bark - Herbal EncyclopediaFever Bark - Herbal Encyclopedia
In the past the Alstonia tree, also known as Milkwood because of its milky sap, provided a popular fever tonic which was thought to rival quinine.. The bitter taste contributed to its nickname of Bitter Bark and which led to its reputation as a quinine alternative since that plant was equally bitter. It could not fully rival that of the cinchona (quinine) species, but it did eventually prove to be a useful medicine for other reasons, especially in lowering blood pressure.. The Aborigines collected the sap on a twig and put it on small sores. It was handled with great care, as eye contact could cause blindness. ...

Combating malaria in Solomon Islands | Global EducationCombating malaria in Solomon Islands | Global Education
Early treatment reduces the severity and length of the illness. Quinine harvested from the bark of the cinchona tree in present-day Peru and Ecuador was traditionally the main form of treatment. While quinine interrupts the parasites breeding cycle, it is short acting and can have serious side effects.. In the 1940s a synthetic medicine, chloroquine, was introduced. It was inexpensive, safe and provided long-lasting protection against all forms of malaria. However, poor usage led to the development of resistance.. Since the 1980s a new drug based on a traditional Chinese herb, qinghaosu, has been used. The active ingredient is artemisinin, and it has significantly contributed to the decline of malaria. Artemisinin is used in combination with other drugs to reduce the development of resistance. ...

Cattle will develop a taste for locoweed that can prove fatal; bighorn sheep will grind their teeth to useless nubs scraping a hallucinogenic lichen off ledge rock. Siegel suggests that some of these adventurous animals serves as our Virgils in the garden of psychoactive plants. Goats, who will try a little bit of anything, probably deserve credit for the discovery of coffee: Abyssinian herders in the tenth century observed that their animals would become particularly frisky after nibbling the shrubs bright red berries. Pigeons spacing out on cannabis seeds (a favorite food of many birds) may have tipped off the ancient Chinese (or Aryans or Scythians) to that plants special properties. Peruvian legend has it that the puma discovered quinine: Indians observed that sick cats were often restored to health after eating the bark of the cinchona tree. Tukano Indians in the Amazon noticed that jaguars, not ordinarily herbivorous, would eat the bark of the yaje vine and hallucinate; the Indians who ...

Lipase-catalyzed asymmetric synthesis of oxathiazinanones through dynamic covalent kinetic resolutionLipase-catalyzed asymmetric synthesis of oxathiazinanones through dynamic covalent kinetic resolution
This thesis is built on the concepts of constitutional dynamic chemistry and dynamic kinetic resolution, where reversible covalent reactions are used to generate dynamics and kinetically controlled reactions are employed for resolution. The thesis is divided into two parts:. The first section focuses on the study of dynamic systemic resolution, a concept derived from constitutional dynamic chemistry. Three projects are addressed in this section: 1) lipase-catalyzed resolution of a double parallel dynamic system involving both hemiacetal formation and nitroaldol reaction; 2) resolution of a dynamic α-iminonitrile system through a silver-catalyzed 1,3-dipolar cycloaddition process; 3) resolution of a dynamic imine system via organogelation. Both external and internal selection pressures are applied for the resolution of complex dynamic systems.. The second section explores the asymmetric synthesis of two types of heterocycles through dynamic kinetic resolution. In the first example, a series of ...

The first direct asymmetric synthetic preparation of trifluoro-1-(indol-3-yl)ethanols (TFIEs) is described by an enantioselective organocatalytic method from indoles and inexpensive trifluoroacetaldehyde methyl hemiacetal. The reaction is catalyzed by hydroquinine to produce TFIEs in an almost quantitative yield and with enantioselectivities up to 75% at room temperature. The enantioselectivity is strongly dependent on the concentration of substrates and catalyst due to the competitive noncatalyzed reaction. Chirality, 2011. © 2011 Wiley-Liss, Inc.

Di-tert-butyl azodicarboxylate is a reagent used in the preparation of acyl hydrazinedicarboxylates. It is also used in the electrophilic amination of beta-keto esters catalyzed by an axially chiral guanidine. It serves as a precursor in an enantioselective synthesis of 3,6-dihyropyridazines employing organocatalysts such as L-proline or (S)-2-pyrrolidinyl tetrazole. It is also utilized in the asymmetric Friedel-Crafts amination through a chiral organocatalyst. Further, it acts as a reactant for preparation of hexapeptide key fragments through stereo selective selenocyclization/oxidative deselenylation reactions. In addition to this, it is employed as a starting material in the synthesis of pyrroloisoquinoline template through stereoselective N-acyliminium-mediated cyclization and enolate amination for preparation of peptidomimetic compounds and Barbier-type propargylation reactions ...

Cinchonine1
Rubiaceae4
Calisaya3
Crystalline alkaloid1
Antimalarial Alkaloids1
Catalysts1
  • Bis-(cinchona alkaloid) ligands (which are generally the better catalysts) catalyze the formation of diols of high enantiopurity from a very broad range of olefins. (sigmaaldrich.com)
Malaria1
Cinchonidine2
  • A significant phylogenetic signal was found for the content of two out of four major Cinchona alkaloids (quinine and cinchonidine) and their total content. (frontiersin.org)
  • Cinchonidine sulphate, (C 19 H 22 N 2 O) 2 ,H 2 SO 4 ,3H 2 O, is the salt of a base found in cinchona bark. (henriettes-herb.com)
Bark of the cinchona tree1
Chiral3
  • Synthetically modified cinchona alkaloids are typical chiral organocatalysts used in asymmetric PTC. (sigmaaldrich.com)
  • Cinchona alkaloids and their derivatives have proven to catalyze an astonishing array of enantioselective transformations, providing access to chiral products of high enantiopurity. (sigmaaldrich.com)
  • In connection with our ongoing project that deals with the catalytic potential of the cinchona-alkaloid-derived amides,[17-19] we became interested in examining the reaction of allenoates with imines in the presence of a chiral tertiary amine catalyst. (docme.ru)
South America1
  • The medicinal value of Cinchona bark was first discovered in Loxa (now Loja, Ecuador) in the seventeenth century by Jesuit monks, and soon exports of different varieties of Cinchona pubescens Vahl (red bark) from South America to Europe were reaching half a million kilograms bark per year ( Roersch van der Hoogte and Pieters, 2015 ). (frontiersin.org)
Enantioselectivities2
  • In an attempt to further improve catalyst enantioselectivities, Jew and Park linked two cinchona alkaloid moieties via spacer units. (sigmaaldrich.com)
  • In particular, the cinchona alkaloids catalyze many useful processes with high enantioselectivities. (sigmaaldrich.com)
Succirubra2
Species2
  • Climatic and soil parameters were characterized and bark samples were analyzed for content of the four major alkaloids using HPLC-UV to explore the utility of evolutionary history (phylogeny) in determining variation within species of these compounds under natural conditions. (frontiersin.org)
  • At the present time (1917) thirty or forty more or less clearly defined species of Cinchona are recognized. (henriettes-herb.com)
Substrates1
  • Cinchona alkaloids can be used as bases to deprotonate substrates with relatively acidic protons forming a contact ion pair between the resulting anion and protonated amine. (sigmaaldrich.com)
Asymmetric1
  • Subsequently, these cinchona alkaloids were used for the osmium-catalyzed asymmetric aminohydroxylation of olefins. (sigmaaldrich.com)
Plants1
  • Cinchona is classified in the division Magnoliophyta Magnoliophyta , division of the plant kingdom consisting of those organisms commonly called the flowering plants, or angiosperms. (thefreedictionary.com)
Europeans1
  • Despite a ban on export, Europeans sent cinchona seeds and seedlings to Java and India, where plantations were established. (thefreedictionary.com)
Hybrids2
  • Of all of these probably but four with their cultivated hybrids yield the Cinchona Bark of commerce. (henriettes-herb.com)
  • The literature of the cinchona hybrids is hopelessly confused by the same name being frequently used by different authorities for the different hybrids and the one hybrid having various names. (henriettes-herb.com)
Plantations1
  • Import could not meet demand, and a quest began for the most productive source of Cinchona trees to establish plantations by the British, Dutch, and French empires. (frontiersin.org)
Trees1
  • A clade of high alkaloid producing trees was identified that spanned a narrow range of altitudes, from 1,100 to 1,350 m. (frontiersin.org)
Tree1
Dutch1
  • So successful were the Dutch and English in transplanting cinchona to Java and India that until World War II these countries, especially Java, grew practically the entire commercial supply. (thefreedictionary.com)
Europe1
  • Four years later, Linne proposed a new name, Cinchona , in honor of the Countess of Chinchon, who first made the bark known in Europe. (henriettes-herb.com)
Content1
  • As a result of selection, the alkaloid content in the bark was raised from 2-2.5 percent to 16 percent. (thefreedictionary.com)
