It has been used as an antihypertensive and an antipsychotic as well as a research tool, but its adverse effects limit its clinical use. The FDA withdrew its approval for the use of all oral dosage form drug products containing more than 1 mg of reserpine. Reserpine is a Catecholamine-depleting Sympatholytic. The physiologic effect of reserpine is by means of Decreased Sympathetic Activity. Reserpine is an oral antihypertensive medication that acts through inhibitor of alpha-adrenergic transmission and was one of the first antihypertensive agents introduced into clinical practice. Despite widescale use for many years, reserpine has not been shown to cause clinically apparent liver injury. Reserpine is a natural product found in Rauvolfia yunnanensis, Alstonia constricta, and other organisms with data available. Reserpine is an alkaloid, derived from the roots of Rauwolfia serpentine and vomitoria, and an adrenergic uptake inhibitor with antihypertensive effects. Reserpine is lipid soluble and can penetrate blood-brain barrier. This agent binds and inhibits catecholamine pump on the storage vesicles in central and peripheral adrenergic neurons, thereby inhibiting the uptake of norepinephrine, dopamine serotonin into presynaptic storage vesicles. This results in catecholamines and serotonin lingering in the cytoplasm where they are destroyed by intraneuronal monoamine oxidase, thereby causing the depletion of catecholamine and serotonin stores in central and peripheral nerve terminals. Depletion results in a lack of active transmitter discharge from nerve endings upon nerve depolarization, and consequently leads to a decreased heart rate and decreased arterial blood pressure as well as sedative effects.

Quercetin

C15H10O7 (302.0427)

Quercetin appears as yellow needles or yellow powder. Converts to anhydrous form at 203-207 °F. Alcoholic solutions taste very bitter. (NTP, 1992) Quercetin is a pentahydroxyflavone having the five hydroxy groups placed at the 3-, 3-, 4-, 5- and 7-positions. It is one of the most abundant flavonoids in edible vegetables, fruit and wine. It has a role as an antibacterial agent, an antioxidant, a protein kinase inhibitor, an antineoplastic agent, an EC 1.10.99.2 [ribosyldihydronicotinamide dehydrogenase (quinone)] inhibitor, a plant metabolite, a phytoestrogen, a radical scavenger, a chelator, an Aurora kinase inhibitor and a geroprotector. It is a pentahydroxyflavone and a 7-hydroxyflavonol. It is a conjugate acid of a quercetin-7-olate. Quercetin is a flavonol widely distributed in plants. It is an antioxidant, like many other phenolic heterocyclic compounds. Glycosylated forms include RUTIN and quercetrin. Quercetin is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Quercetin is a flavonoid found in many foods and herbs and is a regular component of a normal diet. Extracts of quercetin have been used to treat or prevent diverse conditions including cardiovascular disease, hypercholesterolemia, rheumatic diseases, infections and cancer but have not been shown to be effective in clinical trials for any medical condition. Quercetin as a nutritional supplement is well tolerated and has not been linked to serum enzyme elevations or to episodes of clinically apparent liver injury. Quercetin is a natural product found in Lotus ucrainicus, Visnea mocanera, and other organisms with data available. Quercetin is a polyphenolic flavonoid with potential chemopreventive activity. Quercetin, ubiquitous in plant food sources and a major bioflavonoid in the human diet, may produce antiproliferative effects resulting from the modulation of either EGFR or estrogen-receptor mediated signal transduction pathways. Although the mechanism of action of action is not fully known, the following effects have been described with this agent in vitro: decreased expression of mutant p53 protein and p21-ras oncogene, induction of cell cycle arrest at the G1 phase and inhibition of heat shock protein synthesis. This compound also demonstrates synergy and reversal of the multidrug resistance phenotype, when combined with chemotherapeutic drugs, in vitro. Quercetin also produces anti-inflammatory and anti-allergy effects mediated through the inhibition of the lipoxygenase and cyclooxygenase pathways, thereby preventing the production of pro-inflammatory mediators. Quercetin is a flavonoid widely distributed in many plants and fruits including red grapes, citrus fruit, tomato, broccoli and other leafy green vegetables, and a number of berries, including raspberries and cranberries. Quercetin itself (aglycone quercetin), as opposed to quercetin glycosides, is not a normal dietary component. Quercitin glycosides are converted to phenolic acids as they pass through the gastrointestinal tract. Quercetin has neither been confirmed scientifically as a specific therapeutic for any condition nor been approved by any regulatory agency. The U.S. Food and Drug Administration has not approved any health claims for quercetin. Nevertheless, the interest in dietary flavonoids has grown after the publication of several epidemiological studies showing an inverse correlation between dietary consumption of flavonols and flavones and reduced incidence and mortality from cardiovascular disease and cancer. In recent years, a large amount of experimental and some clinical data have accumulated regarding the effects of flavonoids on the endothelium under physiological and pathological conditions. The meta-analysis of seven prospective cohort studies concluded that the individuals in the top third of dietary flavonol intake are associated with a reduced risk of mortality from coronary heart disease as compared with those in the bottom third, after adju...

Palmitic acid

C16H32O2 (256.2402)

Palmitic acid, also known as palmitate or hexadecanoic acid, is a member of the class of compounds known as long-chain fatty acids. Long-chain fatty acids are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Thus, palmitic acid is considered to be a fatty acid lipid molecule. Palmitic acid is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Palmitic acid can be found in a number of food items such as sacred lotus, spinach, shallot, and corn salad, which makes palmitic acid a potential biomarker for the consumption of these food products. Palmitic acid can be found primarily in most biofluids, including feces, sweat, cerebrospinal fluid (CSF), and urine, as well as throughout most human tissues. Palmitic acid exists in all living species, ranging from bacteria to humans. In humans, palmitic acid is involved in several metabolic pathways, some of which include alendronate action pathway, rosuvastatin action pathway, simvastatin action pathway, and cerivastatin action pathway. Palmitic acid is also involved in several metabolic disorders, some of which include hypercholesterolemia, familial lipoprotein lipase deficiency, ethylmalonic encephalopathy, and carnitine palmitoyl transferase deficiency (I). Moreover, palmitic acid is found to be associated with schizophrenia. Palmitic acid is a non-carcinogenic (not listed by IARC) potentially toxic compound. Palmitic acid, or hexadecanoic acid in IUPAC nomenclature, is the most common saturated fatty acid found in animals, plants and microorganisms. Its chemical formula is CH3(CH2)14COOH, and its C:D is 16:0. As its name indicates, it is a major component of the oil from the fruit of oil palms (palm oil). Palmitic acid can also be found in meats, cheeses, butter, and dairy products. Palmitate is the salts and esters of palmitic acid. The palmitate anion is the observed form of palmitic acid at physiologic pH (7.4) . Palmitic acid is the first fatty acid produced during lipogenesis (fatty acid synthesis) and from which longer fatty acids can be produced. Palmitate negatively feeds back on acetyl-CoA carboxylase (ACC) which is responsible for converting acetyl-ACP to malonyl-ACP on the growing acyl chain, thus preventing further palmitate generation (DrugBank). Palmitic acid, or hexadecanoic acid, is one of the most common saturated fatty acids found in animals, plants, and microorganisms. As its name indicates, it is a major component of the oil from the fruit of oil palms (palm oil). Excess carbohydrates in the body are converted to palmitic acid. Palmitic acid is the first fatty acid produced during fatty acid synthesis and is the precursor to longer fatty acids. As a consequence, palmitic acid is a major body component of animals. In humans, one analysis found it to make up 21–30\\\% (molar) of human depot fat (PMID: 13756126), and it is a major, but highly variable, lipid component of human breast milk (PMID: 352132). Palmitic acid is used to produce soaps, cosmetics, and industrial mould release agents. These applications use sodium palmitate, which is commonly obtained by saponification of palm oil. To this end, palm oil, rendered from palm tree (species Elaeis guineensis), is treated with sodium hydroxide (in the form of caustic soda or lye), which causes hydrolysis of the ester groups, yielding glycerol and sodium palmitate. Aluminium salts of palmitic acid and naphthenic acid were combined during World War II to produce napalm. The word "napalm" is derived from the words naphthenic acid and palmitic acid (Wikipedia). Palmitic acid is also used in the determination of water hardness and is a surfactant of Levovist, an intravenous ultrasonic contrast agent. Hexadecanoic acid is a straight-chain, sixteen-carbon, saturated long-chain fatty acid. It has a role as an EC 1.1.1.189 (prostaglandin-E2 9-reductase) inhibitor, a plant metabolite, a Daphnia magna metabolite and an algal metabolite. It is a long-chain fatty acid and a straight-chain saturated fatty acid. It is a conjugate acid of a hexadecanoate. A common saturated fatty acid found in fats and waxes including olive oil, palm oil, and body lipids. Palmitic acid is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Palmitic Acid is a saturated long-chain fatty acid with a 16-carbon backbone. Palmitic acid is found naturally in palm oil and palm kernel oil, as well as in butter, cheese, milk and meat. Palmitic acid, or hexadecanoic acid is one of the most common saturated fatty acids found in animals and plants, a saturated fatty acid found in fats and waxes including olive oil, palm oil, and body lipids. It occurs in the form of esters (glycerides) in oils and fats of vegetable and animal origin and is usually obtained from palm oil, which is widely distributed in plants. Palmitic acid is used in determination of water hardness and is an active ingredient of *Levovist*TM, used in echo enhancement in sonographic Doppler B-mode imaging and as an ultrasound contrast medium.

Stigmasterol

C29H48O (412.3705)

Stigmasterol is a phytosterol, meaning it is steroid derived from plants. As a food additive, phytosterols have cholesterol-lowering properties (reducing cholesterol absorption in intestines), and may act in cancer prevention. Phytosterols naturally occur in small amount in vegetable oils, especially soybean oil. One such phytosterol complex, isolated from vegetable oil, is cholestatin, composed of campesterol, stigmasterol, and brassicasterol, and is marketed as a dietary supplement. Sterols can reduce cholesterol in human subjects by up to 15\\%. The mechanism behind phytosterols and the lowering of cholesterol occurs as follows : the incorporation of cholesterol into micelles in the gastrointestinal tract is inhibited, decreasing the overall amount of cholesterol absorbed. This may in turn help to control body total cholesterol levels, as well as modify HDL, LDL and TAG levels. Many margarines, butters, breakfast cereals and spreads are now enriched with phytosterols and marketed towards people with high cholesterol and a wish to lower it. Stigmasterol is found to be associated with phytosterolemia, which is an inborn error of metabolism. Stigmasterol is a 3beta-sterol that consists of 3beta-hydroxystigmastane having double bonds at the 5,6- and 22,23-positions. It has a role as a plant metabolite. It is a 3beta-sterol, a stigmastane sterol, a 3beta-hydroxy-Delta(5)-steroid and a member of phytosterols. It derives from a hydride of a stigmastane. Stigmasterol is a natural product found in Ficus auriculata, Xylopia aromatica, and other organisms with data available. Stigmasterol is a steroid derivative characterized by the hydroxyl group in position C-3 of the steroid skeleton, and unsaturated bonds in position 5-6 of the B ring, and position 22-23 in the alkyl substituent. Stigmasterol is found in the fats and oils of soybean, calabar bean and rape seed, as well as several other vegetables, legumes, nuts, seeds, and unpasteurized milk. See also: Comfrey Root (part of); Saw Palmetto (part of); Plantago ovata seed (part of). Stigmasterol is an unsaturated plant sterol occurring in the plant fats or oils of soybean, calabar bean, and rape seed, and in a number of medicinal herbs, including the Chinese herbs Ophiopogon japonicus (Mai men dong) and American Ginseng.

beta-Sitosterol

C29H50O (414.3861)

beta-Sitosterol, a main dietary phytosterol found in plants, may have the potential for prevention and therapy for human cancer. Phytosterols are plant sterols found in foods such as oils, nuts, and vegetables. Phytosterols, in the same way as cholesterol, contain a double bond and are susceptible to oxidation, and are characterized by anti-carcinogenic and anti-atherogenic properties (PMID:13129445, 11432711). beta-Sitosterol is a phytopharmacological extract containing a mixture of phytosterols, with smaller amounts of other sterols, bonded with glucosides. These phytosterols are commonly derived from the South African star grass, Hypoxis rooperi, or from species of Pinus and Picea. The purported active constituent is termed beta-sitosterol. Additionally, the quantity of beta-sitosterol-beta-D-glucoside is often reported. Although the exact mechanism of action of beta-sitosterols is unknown, it may be related to cholesterol metabolism or anti-inflammatory effects (via interference with prostaglandin metabolism). Compared with placebo, beta-sitosterol improved urinary symptom scores and flow measures (PMID:10368239). A plant food-based diet modifies the serum beta-sitosterol concentration in hyperandrogenic postmenopausal women. This finding indicates that beta-sitosterol can be used as a biomarker of exposure in observational studies or as a compliance indicator in dietary intervention studies of cancer prevention (PMID:14652381). beta-Sitosterol induces apoptosis and activates key caspases in MDA-MB-231 human breast cancer cells (PMID:12579296). Sitosterol is a member of the class of phytosterols that is stigmast-5-ene substituted by a beta-hydroxy group at position 3. It has a role as a sterol methyltransferase inhibitor, an anticholesteremic drug, an antioxidant, a plant metabolite and a mouse metabolite. It is a 3beta-sterol, a stigmastane sterol, a 3beta-hydroxy-Delta(5)-steroid, a C29-steroid and a member of phytosterols. It derives from a hydride of a stigmastane. Active fraction of Solanum trilobatum; reduces side-effects of radiation-induced toxicity. Beta-Sitosterol is a natural product found in Elodea canadensis, Ophiopogon intermedius, and other organisms with data available. beta-Sitosterol is one of several phytosterols (plant sterols) with chemical structures similar to that of cholesterol. Sitosterols are white, waxy powders with a characteristic odor. They are hydrophobic and soluble in alcohols. beta-Sitosterol is found in many foods, some of which are ginseng, globe artichoke, sesbania flower, and common oregano.

Betulinic acid is a naturally occurring pentacyclic triterpenoid which has anti-retroviral, anti-malarial, and anti-inflammatory properties, as well as a more recently discovered potential as an anticancer agent, by inhibition of topoisomerase. It is found in the bark of several species of plants, principally the white birch (Betula pubescens) from which it gets its name, but also the Ber tree (Ziziphus mauritiana), the tropical carnivorous plants Triphyophyllum peltatum and Ancistrocladus heyneanus, Diospyros leucomelas a member of the persimmon family, Tetracera boiviniana, the jambul (Syzygium formosanum), flowering quince (Chaenomeles sinensis), Rosemary, and Pulsatilla chinensis. Controversial is a role of p53 in betulinic acid-induced apoptosis. Fulda suggested p53-independent mechanism of the apoptosis, basing on fact of no accumulation of wild-type p53 detected upon treatment with the betulinic acid, whereas wild-type p53 protein strongly increased after treatment with doxorubicin. The suggestion is supported by study of Raisova. On the other hand Rieber suggested that betulinic acid exerts its inhibitory effect on human metastatic melanoma partly by increasing p53 A pentacyclic triterpenoid that is lupane having a double bond at position 20(29) as well as 3beta-hydroxy and 28-carboxy substituents.

Rescinnamine

C35H42N2O9 (634.289)

Rescinnamine is only found in individuals that have used or taken this drug. It is an angiotensin-converting enzyme inhibitor used as an antihypertensive drug. It is an alkaloid obtained from Rauwolfia serpentina and other species of Rauwolfia. [Wikipedia]Rescinnamine Binds to and inhibits the angiotensin converting enzyme. Rescinnamine competes with angiotensin I for binding at the angiotensin-converting enzyme, blocking the conversion of angiotensin I to angiotensin II. Inhibition of ACE results in decreased plasma angiotensin II. As angiotensin II is a vasoconstrictor and a negative-feedback mediator for renin activity, lower concentrations result in a decrease in blood pressure and stimulation of baroreceptor reflex mechanisms, which leads to decreased vasopressor activity and to decreased aldosterone secretion.

Ajmaline

C20H26N2O2 (326.1994)

Ajmaline, also known as (+)-ajmaline, is a member of the class of compounds known as ajmaline-sarpagine alkaloids. Ajmaline-sarpagine alkaloids are organic compounds containing either of the ajmalan, sarpagan skeleton, or derivative thereof. The Sarpagine (Akuammidine) group, based on the sarpagan nucleus, arises from bond formation between C-16 and C-5 of the corynantheine precursor. Ajmaline alkaloids are based on a 17,19-secoyohimban skeleton (oxayohimban) which is invariably present as an ether. Ajmaline is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Ajmaline can be synthesized from ajmalan. Ajmaline is also a parent compound for other transformation products, including but not limited to, vinorine, norajmaline, and 17-O-acetylajmaline. Ajmaline can be found in a number of food items such as soursop, jews ear, small-leaf linden, and soft-necked garlic, which makes ajmaline a potential biomarker for the consumption of these food products. Ajmaline can be found primarily in blood and urine. Ajmaline is a drug which is used for use as an antiarrhythmic agent. The compound was first isolated by Salimuzzaman Siddiqui in 1931 from the roots of Rauvolfia serpentina. He named it ajmaline, after Hakim Ajmal Khan, one of the most illustrious practitioners of Unani medicine in South Asia. Ajmaline can be found in most species of the Rauvolfia genus as well as Catharanthus roseus. In addition to Southeast Asia, Rauvolfia species have also been found in tropical regions of India, Africa, South America, and some oceanic islands. Other indole alkaloids found in Rauvolfia include reserpine, ajmalicine, serpentine, corynanthine, and yohimbine. While 86 alkaloids have been discovered throughout Rauvolfia vomitoria, ajmaline is mainly isolated from the stem bark and roots of the plant . The class I antiarrhythmic agents interfere with the sodium channel. A class IA agent lengthens the action potential (right shift) which brings about improvement in abnormal heart rhythms. This drug in particular has a high affinity for the Nav 1.5 sodium channel (DrugBank). An alkaloid found in the root of Rauwolfia serpentina, among other plant sources. It is a class Ia antiarrhythmic agent that apparently acts by changing the shape and threshold of cardiac action potentials. Ajmaline produces potent sodium channel blocking effects and a very short half-life which makes it a very useful drug for acute intravenous treatments. The drug has been very popular in some countries for the treatment of atrial fibrillation in patients with the Wolff Parkinson White syndrome and in well tolerated monomorphic ventricular tachycardias. It has also been used for many years as a drug to challenge the conduction system of the heart in cases of bundle branch block and syncope. In these cases, abnormal prolongation of the HV interval has been taken as a proof for infrahisian conduction defects tributary for permanent pacemaker implantation.

Cholesterol

C27H46O (386.3548)

Cholesterol is a sterol (a combination steroid and alcohol) and a lipid found in the cell membranes of all body tissues and transported in the blood plasma of all animals. The name originates from the Greek chole- (bile) and stereos (solid), and the chemical suffix -ol for an alcohol. This is because researchers first identified cholesterol in solid form in gallstones in 1784. In the body, cholesterol can exist in either the free form or as an ester with a single fatty acid (of 10-20 carbons in length) covalently attached to the hydroxyl group at position 3 of the cholesterol ring. Due to the mechanism of synthesis, plasma cholesterol esters tend to contain relatively high proportions of polyunsaturated fatty acids. Most of the cholesterol consumed as a dietary lipid exists as cholesterol esters. Cholesterol esters have a lower solubility in water than cholesterol and are more hydrophobic. They are hydrolyzed by the pancreatic enzyme cholesterol esterase to produce cholesterol and free fatty acids. Cholesterol has vital structural roles in membranes and in lipid metabolism in general. It is a biosynthetic precursor of bile acids, vitamin D, and steroid hormones (glucocorticoids, estrogens, progesterones, androgens and aldosterone). In addition, it contributes to the development and functioning of the central nervous system, and it has major functions in signal transduction and sperm development. Cholesterol is a ubiquitous component of all animal tissues where much of it is located in the membranes, although it is not evenly distributed. The highest proportion of unesterified cholesterol is in the plasma membrane (roughly 30-50\\\\% of the lipid in the membrane or 60-80\\\\% of the cholesterol in the cell), while mitochondria and the endoplasmic reticulum have very low cholesterol contents. Cholesterol is also enriched in early and recycling endosomes, but not in late endosomes. The brain contains more cholesterol than any other organ where it comprises roughly a quarter of the total free cholesterol in the human body. Of all the organic constituents of blood, only glucose is present in a higher molar concentration than cholesterol. Cholesterol esters appear to be the preferred form for transport in plasma and as a biologically inert storage (de-toxified) form. They do not contribute to membranes but are packed into intracellular lipid particles. Cholesterol molecules (i.e. cholesterol esters) are transported throughout the body via lipoprotein particles. The largest lipoproteins, which primarily transport fats from the intestinal mucosa to the liver, are called chylomicrons. They carry mostly triglyceride fats and cholesterol that are from food, especially internal cholesterol secreted by the liver into the bile. In the liver, chylomicron particles give up triglycerides and some cholesterol. They are then converted into low-density lipoprotein (LDL) particles, which carry triglycerides and cholesterol on to other body cells. In healthy individuals, the LDL particles are large and relatively few in number. In contrast, large numbers of small LDL particles are strongly associated with promoting atheromatous disease within the arteries. (Lack of information on LDL particle number and size is one of the major problems of conventional lipid tests.). In conditions with elevated concentrations of oxidized LDL particles, especially small LDL particles, cholesterol promotes atheroma plaque deposits in the walls of arteries, a condition known as atherosclerosis, which is a major contributor to coronary heart disease and other forms of cardiovascular disease. There is a worldwide trend to believe that lower total cholesterol levels tend to correlate with lower atherosclerosis event rates (though some studies refute this idea). As a result, cholesterol has become a very large focus for the scientific community trying to determine the proper amount of cholesterol needed in a healthy diet. However, the primary association of atherosclerosis with c... Constituent either free or as esters, of fish liver oils, lard, dairy fats, egg yolk and bran Cholesterol is the major sterol in mammals. It is making up 20-25\\% of structural component of the plasma membrane. Plasma membranes are highly permeable to water but relatively impermeable to ions and protons. Cholesterol plays an important role in determining the fluidity and permeability characteristics of the membrane as well as the function of both the transporters and signaling proteins[1][2]. Cholesterol is also an endogenous estrogen-related receptor α (ERRα) agonist[3]. Cholesterol is the major sterol in mammals. It is making up 20-25\% of structural component of the plasma membrane.
