Huperzine A is an alkaloid isolated from the plant Huperzia serrata. The plant is commonly called the toothed clubmoss, and is native to India and Southeast Asia. Evidence suggests that huperzine A is an acetylcholinesterase inhibitor. A number of studies suggest that huperzine A may improve memory and may be useful in the treatment of age-related memory deficit, Alzheimers disease, or simply as a nootropic to enhance learning and memory. However, huperzine A also shows the ability to protect neurones in the brain from damage caused by experimental stressors, and therefore may be considered a neuroprotective agent. It is thought that huperzine is neuroprotective because it acts as an antioxidant in tissues and this prevents oxidative stress, a major cause of neuronal damage. Huperzine A is used in traditional Chinese medicine as a memory enhancer and the alkaloid has become popular as a dietary supplement in the West where it is marketed as a nootropic.

The Stemona alkaloids are an expanding group of natural products that have significant potential as agricultural and pharmaceutical drugs. However many of these alkaloids are only available in small quantities which severely limits their application. A significant and innovative aspect of this project will be the development of new processes for the large scale production of Stemona alkaloids. The major alkaloids will be used as novel building blocks to prepare more structurally complex and less abundant Stemona alkaloids and their analogues. These studies will allow systematic structure-biological activity relationship studies to be performed ...

The isolated rat uterus contraction induced by oxytocin and Ca+ + after high-K depolarization were markedly inhibited by tetrandrine (Tet). The depression was immediately reversed by addition of Ca++ to the bath fluid. Tet and verapamil (Ver), which shifted the cumulative dose-response curves to the right and depressed the maximal responses to CaCl2 acted as non-competitive antagonists. The oxytocin-induced Ca++-dependent contractions were depressed by 4.8 and 30 μM Tet. Tet 30 μM also inhibited the Ca++ o-dependent component of the contraction. The effect of Ver on isolated rat uterus was stronger than that of Tet. But up to 0.05 μM, it showed no effect on Ca+ +-dependent oxytocin contraction. These results indicate that Tet is an effective Ca+ +-antagonist very similar to Ver on isolated rat uteri.

What is huperzine A? Huperzine A is a natural alkaloid extracted from Huperzia serrata, a variety of club moss cultivated in China and other Asian locales. The plant has long been used to create qian ceng ta, a health-enhancing extract that is considered a cornerstone of traditional Chinese wellness practices. The folk use of Huperzia serrata led to scientific investigations of its key compound, which was discovered during the 1980s and has been increasingly researched in recent decades.. Studies have shown that that huperzine A promotes multiple aspects of cognitive function, including sharp memory, clear focus, mental alertness and enhanced learning capacity. Additional evidence suggests it may help with age-related cognitive impairment, memory decline and other mental processing problems related to degenerative brain issues. It is considered a neuroprotective compound that helps to defend brain cells from oxidative stress and toxicity.. Research has indicated that huperzine A, unlike many ...

Azagthoth might have you think that the song is going to be nothing but five and a half minutes of Morbid Angel Solos. That is not the case and this track might be one of the most bizarre and experimental tracks on the record. Musically Azagthoth opens with what sounds like dueling classical guitars with a third distorted line following along. The third distorted line is for the most part, harmonic, chaotic dissonance. Moreans clean vocals return on this one. This is one of those projects that probably will never play live although I wish they did. It is one thing to sit here and listen to sounds arranged for three guitars and it is another to witness this live. Alkaloid are one of those groups that have such intricate arrangements that I would be interested to see if they could pull off these tunes live. So many Notes!. The title track Liquid Anatomy is the probably the closest thing to a ballad on the record. The track opens up with melodious acoustic twelve string guitars before ...

Isoliensinine, a natural phenolic bisbenzyltetrahydroisoquinoline alkaloid, has received considerable attention for its potential biological effects such as antioxidant and anti-HIV activities. From the dog hepatic microsomes of isoliensinine, three new N-demethylated and O-demethylated metabolites, 2-N-desmethyl-isoliensinine (M1), 2-N-desmethylisoliensinine (M2), and 2-N-6-O-didesmethylisoliensinine (M3), were identified by high-performance liquid chromatography and data-dependent electrospray ionization tandem mass spectrometry. Possible metabolic pathways for isoliensinine have been proposed. The result should prove very helpful for evaluation of the drug-like properties of isoliensinine and other bisbenzylisoquinoline alkaloids.

Alkaloid-containing plants have been used by humans since ancient times for therapeutic and recreational purposes. For example, medicinal plants have been known in the Mesopotamia at least around 2000 BC.[27] The Odyssey of Homer referred to a gift given to Helen by the Egyptian queen, a drug bringing oblivion. It is believed that the gift was an opium-containing drug.[28] A Chinese book on houseplants written in 1st-3rd centuries BC mentioned a medical use of Ephedra and opium poppies.[29] Also, coca leaves have been used by South American Indians since ancient times.[30] Extracts from plants containing toxic alkaloids, such as aconitine and tubocurarine, were used since antiquity for poisoning arrows.[27] Studies of alkaloids began in the 19th century. In 1804, the German chemist Friedrich Sertürner isolated from opium a soporific principle (Latin: principium somniferum), which he called morphium in honor of Morpheus, the Greek god of dreams; in German and some other Central-European ...

UV-B radiation has been widely documented as a stressor for plants that can cause decreased biomass, reduction in photosynthesis, and oxidative stress. Trigonelline is a secondary metabolite that is biosynthesized in some plants in response to abiotic stress such as UV-B irradiation. The objectives of this study were to examine biochemical stress responses for peanut plants (Arachis hypogaea L.) of four different genotypes (Spanish, Valencia, Virginia, and Runner) after exposure at various lengths to UV-B radiation and to examine the alteration of trigonelline biosynthesis due to the age of the plants. Peanut plants from the genotypes were exposed to UV-B radiation at three exposure times (60, 120, and 180 min); plants from two growth stages, the flowering (R1) and early maturity (R7), were used. Significant positive correlations (rs 0.29-0.74, P≤0.05) were found for trigonelline concentrations and UV-B exposure times. With longer exposure times of 180 min for plants at R7, trigonelline biosynthesis

How to make kratom extract? there are two main ways of making kratom extract - using water and an alcohol base. while both approaches can yield quality extract and can b performed at home, using an alcohol base is more effective as it will allow preserving alkaloids for a longer period of time. by adding the alkaloid extract, the final kratom product is significantly more potent. generally, kratom extracts tend to have up to 15x more alkaloid content than comparable, standard kratom powders near me. this means that you may be able to use extracts in much smaller quantities. for many, this trade- off is an appealing one. buy kratom resin here. kratom extraction recipe for kratom tea or kratom resin* 1.. grind 28 gm of leaf to a powder and put into a pot filled with 1 liter of water. extraction gently boil, stirring often. when about ½ liter is left, strain the leaves out, and place the liquid aside. she didn pure kratom alkaloid extract t pure kratom alkaloid extract drink at all and was drunk. ...

Ukranian Anti-cancer Institute, Matgaretenstrasse 7, A-1040 Vienna, Austria.. The discovery and development of drugs or agents that could induce either lethal damage to malignant cells directly or via the activation of immune effector cells are two of the major strategies in cancer therapy. Programmed cell death (PCD) or apoptosis is an active cell death process characterised by cell surface blebbing, changes in membrane permeability, nuclear DNA condensation and fragmentation. We have investigated whether Ukrain, an alkaloid thiophosphoric semisynthetic compound, would induce PCD selectively in malignant cells. For this purpose we utilized leukemia K562, HL-60 and THΡ-1 cells m our test panel. As controls, we used normal human PBLs, umbilical vein endothelial cells and human fibroblasts.

Recent research has shown that oxymatrine prevents cardiac fibrosis in rats.[8] The development of fibrotic tissue in the heart occurs when fibroblasts produce excessive amounts of collagen (particularly types I and III),[9] which accumulate and deposit in the heart. The excessive transformation to fibrotic tissue negatively affects the function and structure of the heart. Additionally, excessive amounts of collagen in the ventricles lead to alterations in gene expression, deposition of extracellular matrix, wall thickening, and ventricular remodeling in a manner that promotes dysfunction.[10] The mechanism by which oxymatrine may inhibit fibrosis is still unidentified. One theory that has been proposed is that oxymatrine inhibits a key signaling pathway involved in collagen production. One of the main signaling receptors involved in this pathway is the TGF-β1 co-receptor (complex of type I and type II receptors), which acts as a trans-membrane protein serine/threonine kinase.[11] A receptor ...

Lophocladine A (1) displayed affinity for NMDA receptors and was found to be a δ-opioid receptor antagonist, whereas lophocladine B (2) exhibited cytotoxicity to NCI-H460 human lung tumor and MDA-MB-435 breast cancer cell lines. Immunofluorescence studies indicated that the cytotoxicity of lophocladine B (2) was correlated with microtubule inhibition. This is the first reported occurrence of alkaloids based on a 2,7- ...

3-Pyridylacetic acid is a breakdown product of nicotine (and other tobacco alkaloids) and is part of the nicotine degradation pathway. It is formed from 4-(3-pyridyl)-butanoate. One alkaloid in particular, myosmine, appears to be a major source for 3-pyridylacetic acid. The alkaloid myosmine is present not only in tobacco products but also in various foods. Myosmine is easily nitrosated, yielding 4-hydroxy-1-(3-pyridyl)-1-butanone (HPB) and the esophageal tobacco carcinogen N-nitrosonornicotine. The two major metabolites of myosmine metabolism have been identified as 3-pyridylacetic acid (20-26%) and 4-oxo-4-(3-pyridyl)butyric acid (50-60%) (PMID: 16079272). 3-pyridylacetatic acid is an analog of nicotinic acid.

TY - JOUR. T1 - Molecular determinants of sensitivity or resistance of cancer cells toward sanguinarine. AU - Saeed, Mohamed E.M.. AU - Mahmoud, Nuha. AU - Sugimoto, Yoshikazu. AU - Efferth, Thomas. AU - Abdel-Aziz, Heba. PY - 2018/2/26. Y1 - 2018/2/26. N2 - For decades, natural products represented a significant source of diverse and unique bioactive lead compounds in drug discovery field. In Clinical oncology, complete tumors remission is hampered by the development of drug-resistance. Therefore, development of cytotoxic agents that may overcome drug resistance is urgently needed. Here, the natural benzophenanthridine alkaloid sanguinarine has been studied for its cytotoxic activity against multidrug resistance (MDR) cancer cells. We investigated the role of the ATP-binding cassette (ABC) transporters BCRP/ABCG2, P-glycoprotein/ABCB1 and its close relative ABCB5 in drug resistance. Further drug resistance mechanisms analyzed in this study were the tumor suppressor TP53 and the epidermal growth ...

Apoptosis is vital in maintaining homeostasis, and its deregulation can have dire pathological consequences. Recent years have seen a dramatic increase in interest in the biochemical mechanisms of this phenomenon.;During the later stages of apoptosis there is extensive internucleosomal cleavage of DNA. In the first part of the work, eighteen dinucleosomal fragments from apoptotic mouse thymocytes were sequenced to ascertain whether there were any trends in the sequence of the DNA which could influence its likelihood to be cleaved. No such patterns could be identified.;The second part of this thesis deals with the participation of Ca2+ in the signalling mechanisms that induce apoptosis in rat thymocytes. A comparison of apoptosis induced by thapsigargin, cyclopiazonic acid and 2,5-di-(t-butyl)-1, 4-benzohydroquinone, three inhibitors of the microsomal Ca2+-ATPase, with that caused by the steroid dexamethasone, the chemotherapeutic drug etoposide and the protein kinase inhibitor staurosporine ...

The formation of amyloid β-protein (1-42) (Aβ42) oligomers and Aβ42 oligomer cytotoxicity are two defining characteristics of the etiology of Alzheimers disease (AD). In this study, we found that matrine (Mat) could maintain or even enhance the cytotrophic effect of Aβ42 monomers by inhibiting their aggregation and by working in a manner similar to synergy with Aβ42 monomers. Moreover, Mat could also exert a cytoprotective effect by actively promoting the disaggregation of immature Aβ42 oligomers in a concentration-dependent manner. Although Mat at intermediate concentrations (1-50 μM) exhibited both cytotrophic and cytoprotective effects on SH-SY5Y cells, Mat at higher concentrations (100 μM) only exhibited a cytoprotective effect. Molecular docking studies reveal that these differences are a result of the different interactions between Mat and Aβ42 oligomers that occur at different molecular ratios. Our results support the hypothesis that there may be a Mat-like metabolite in the ...

Last week, Lab Land noticed similarities between two independent lines of research from the Escayg and Traynelis/Yuan labs at Emory. Both were published recently and deal with rare forms of genetic epilepsy, in which molecular understanding of the cause leads to individualized treatment, albeit with limited benefit.. Both conditions are linked to an excess of neuronal excitation, and both can be addressed using medications that have also been tested for Alzheimers. A critical difference is that memantine is FDA-approved for Alzheimers, but huperzine A is not.. ...
