Alcohols are a common form of functionality in organic chemistry, and are often present in biologically active molecules. The protection of hydroxy groups is crucial in long multi-step synthetic routes, as the unprotected alcohol is typically not compatible with many reagents. Alcohols are often protected as corresponding benzyl ether, which can then be removed when desired to reveal the alcohol functional group. Classic methodology for protection of alcohols as benzyl ethers requires harsh conditions utilizing strong acids and bases, which functions well for simple substrates. In more complex multifunctional molecules this can lead to degradation and side products. Therefore, there is a need for the development of milder conditions for the protection of alcohols. Recently a number of reagents have been developed to form benzyl ethers under mild, neutral conditions that and do not disturb the sensitive functionality in complex molecules. Many of these reagents have been based on imidate-type systems.
Benzyl ethers and derivatives are among the most widely used protecting groups in organic synthesis. Cleavage can be effected under a variety of conditions including hydrogenolysis, oxidation, and acid decomposition. Typically, protection of alcohols in the form of a benzyl ether requires harsh reaction conditions. Williamson ether synthesis necessitates strongly basic conditions to generate an alkoxide nucleophile (Figure 1). Alternatively, trichloroacetimidate reagents can be employed in the presence of triflic acid (HOTf) as a promoter. Many complex alcohols are incompatible with these strongly basic or acidic conditions. For example, b-hydroxy esters are prone to elimination, epimerization at the a-carbon, or retro-aldol reactions under acid or base catalysis. Additionally, resident protecting groups on the alcohol substrate may be incompatible with non-pH-neutral reactions. Under acidic conditions, trimethylsilyl (TMS) ethers are easily cleaved, while acetals can undergo migration in polyol ...

Detection of suitable biomarkers of disease is critical for medical diagnosis. However, detection becomes a paradoxical challenge when the biomarker is naturally found in healthy individuals. This is the case for the biomarker hypochlorous acid (HClO), a reactive oxygen species that plays an essential role in maintaining a healthy immune system under normal conditions. Yet, when optimal levels of HClO cannot be maintained by the body, cellular functions become disrupted and this can result in diseases such as atherosclerosis, arthritis, and cancer. Consequently, HClO requires medical monitoring, particularly in the mitochondria where a high concentration tends to reside. To help distinguish between healthy and diseased states, the ideal biosensor must provide fast response, high selectivity, high sensitivity and mitochondrial permeability.. To address this challenge, Xiaojun Peng and colleagues from the Dalian University of Technology in China have created a fluorescent imaging probe to detect ...
Disease Mechanism III: Abnormalities in Energy Metabolism. An Energy Buffer. ---------------------------. Drug Summary: Dichloroacetate stimulates an enzyme called PDC that is essential for the production of energy in cells. Because inefficient energy production is believed to contribute to the progression of HD, dichloroacetate therapy could result in increased energy production, and could possibly help delay HD progression.. The altered huntingtin protein seen in the nerve cells of people with HD has been known to cause a decrease in the amount of energy available in cells by disrupting energy metabolism. (For more on metabolism, click here.) The mitochondria of HD cells appear to be damaged by the altered huntingtin and are unable to perform aerobic respiration, a form of energy metabolism. The mitochondrial damage forces cells to resort to anaerobic respiration, a less efficient form of energy metabolism. The inability to perform efficient aerobic respiration leads to decreased energy ...

An open, prospective evaluation of the effects of dichloroacetate on morbidity and survival time was done in 29 pediatric and adult patients with lactic acidosis. Dichloroacetate was administered intravenously over 30 minutes as two 50 mg/kg body weight doses separated by 2 hours. Five patients underwent retreatment with two additional drug doses and were considered new cases when analyzing for treatment response. Survival, however, was determined from the time of initial entry into the study. Patients were considered to respond to treatment if arterial lactate concentration decreased at least 20% from the pretreatment level within 6 hours of beginning the first dichloroacetate infusion. Using this criterion, 26 cases responded to therapy with dichloroacetate. For all cases, patients mean arterial lactate concentration decreased 52% (P = 0.0009), arterial bicarbonate concentration increased 35% (P = 0.0003), and arterial pH increased (P = 0.024) to normal, defined as the range 7.35 to 7.45. ...

Two dimeric chiral (pyrrolidine salen)Mn(III) complexes 3 and 4 were prepared, in which the two (pyrrolidine salen)Mn(III) units are linked either by a p-xylylene or by ap-phthalyl bridge. High yields were attained for asymmetric epoxidation of styrene and substituted chromenes at 0.5-4.0 mol% catalyst loading of 3 and 4 using NaClO/PPNO and m-CPBA/NMO as oxidant systems, with 37-39% ee for styrene and 86-95% ee for substituted chromenes. Dimeric complexes 3 and 4 displayed higher activities than their parent monomeric complexes 1 and 2 of double equiv for epoxidation of substituted chromenes. Complex 3 bearing two tertiary amine units displayed considerably higher activity than analogous dimeric complex 4 containing two carboxamide units in the aforementioned reaction. The effect of excess CH3I on the epoxidation of 6-nitro-2,2-dimethylchromene catalysed by 3 in the aqueous/organic biphasic medium was explored. The recovery and recycling possibilities of the dimeric complexes 3 and 4 were ...
LaVonne (K6LAV) reported on the June 24th EVAC drill at the Woodland Memorial Hospital. ARES resources were utilized. Crews from the Woodland, Davis, UC Davis, Willow Oak, West Sacramento and Yocha Dehe Fire Departments responded to Woodland Memorial Hospital to participate in the Emergency Victims Assistance Collaboration, an exercise scenario depicting a hospital fire and calling for a large-scale patient evacuation. Red Cross was activated to send Disaster Assistance Teams (DAT) to set up a Rehabilitation tent with water and food for the fire crews. Yolo County Red Cross called up Yolo County ARES to provide communications between the staging area and the Rehabilitation sites. Ken (K6WLS) James (W6JSC), and Greg (KG6SJT), supported Red Cross at the E.V.A.C. Exercise. Radio communications included several ICS-213 messages requisitioning additional resources and tactical messages between Net Control, The Red Cross Rehabilitation sites, and the staging area.

In 2007 it was discovered that the drug DCA (dichloroacetate sodium) induced the death of human breast, lung and brain cancer cells that were implanted into rats, while being non-toxic to healthy cells. This research was published in Cancer Cell, 11, 37-51, January 2007. DCA has been found to kill cancer cells by a newly discovered mechanism that appears to be common to several types of cancer. DCA works by turning on the natural cell suicide system (called apoptosis) which is suppressed in cancerous cells, thus allowing them to die on their own. DCA does not poison the cells like cytotoxic chemotherapy drugs. DCA also interferes with the cancer cells use of glucose, starving the cell of energy. At the same time, it does not starve healthy cells in the body of glucose.. DCA research has accelerated in the last 2 years. The latest research shows that DCA also kills many types of cancer cells, and can boost the cancer-killing effects of radiation. The first formal human cancer research using DCA ...
Oh but they do IF you handle Kh right. The hydrolysis constant = Kh = Kb = (Kw/Ka) or in the case of acids, Kh = Ka = (Kw/Kb). Said another way, the hydrolysis constant, Kh, for ClO^- is just Kb for ClO^-. What the author of the problem has done is s/he has already divided Kw/Ka and given you the answer of 2.86E-7 = Kh. Look in you text for Ka for HClO. My old book gives 3.5E-8 so ...
XPhos is a phosphine ligand derived from biphenyl. Its palladium complexes exhibit high activity for Buchwald-Hartwig amination reactions involving aryl chlorides and aryl tosylates. Both palladium and copper complexes of the compound exhibit high activity for the coupling of aryl halides and aryl tosylates with various amides.[1] It is also an efficient ligand for several commonly used C-C bond-forming cross-coupling reactions, including the Negishi, Suzuki, and the copper-free Sonogashira coupling reactions. It is especially efficient and general when employed as a (2-aminobiphenyl)-cyclometalated palladium mesylate precatalyst complex (Buchwalds third generation precatalyst system), XPhos-G3-Pd, which is commercially available and stable to bench storage.[2][3][4] The ligand itself also has convenient handling characteristics as a crystalline, air-stable solid.[5] ...
between the reactants and products, specifically, between the protonated (HA) and deprotonated (A−) forms of the substance. Paulings second rule[1] states that the value of the first pK for acids of the formula XOm(OH) n is approximately independent of n and X and is approximately 8 for m=0, 2 for m=1, -3 for m=2 and ,-10 for m=3. This correlates with the oxidation state of the central atom, X: the higher the oxidation state the stronger the oxyacid. For example, pKa for HClO is 7.2, for HClO2 is 2.0, for HClO3 is -1 and HClO4 is a strong acid. With organic acids inductive effects and mesomeric effects affect the pKs. The effects are summarised in the Hammett equation and subsequent extensions. Structural effects can also be important. The difference between fumaric acid and maleic acid is a classic example. Fumaric acid is (E)-1,4-but-2-enedioic acid, a trans isomer, whereas maleic acid is the corresponding cis isomer, i.e. (Z)-1,4-but-2-enedioic acid (see cis-trans isomerism). Fumaric acid ...

all about? We live in a society. Each of us is dependant in one way or another on each other and nothing could be truer than in protecting society on the whole from as many dangers as possible. When people can do anything they want regardless of the situation it can affect a great many. The use of DCA off label is Not going to help the Researcher at all, it will hinder him if not in fact prevent him from from finding out whether his trial drug is of any real use. Why? Because It Is about money! It takes money to do clinical trials. Now when people act outside of this even thru certain unethical doctors say in Toronto vicinity who "dont care that they are wrecking a clinical trial" ,Dont care? About who? the Reaseacher or Us? This spreads bad news when they get piss poor results. This means it gets out that there is no sense in supporting a clinical trial. Now how Much Money do you all have to pay for all this unfounded cure or the next one you Will try? This again is the source of of the real ...

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

The trisubstituted enolate is considered the kinetic enolate, while the tetrasubstituted enolate is considered the thermodynamic enolate. The alpha hydrogen deprotonated to form the kinetic enolate is less hindered, and therefore deprotonated more quickly. In general, tetrasubstituted olefins are more stable than trisubstituted olefins due to hyperconjugative stabilization. The ratio of enolate regioisomers is heavily influenced by the choice of base. For the above example, kinetic control may be established with LDA at −78 °C, giving 99:1 selectivity of kinetic: thermodynamic enolate, while thermodynamic control may be established with triphenylmethyllithium at room temperature, giving 10:90 selectivity. In general, kinetic enolates are favored by cold temperatures, conditions that give relatively ionic metal-oxygen bonding, and rapid deprotonation using a slight excess of a strong, sterically hindered base. The large base only deprotonates the more accessible hydrogen, and the low ...
More than 30 alkaloids are known from the bark of this genus. 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. In 1839, William Dawson Hooker, son of ...
