naturally occurring

Pristane (2,6,10,14-tetramethylpentadecane) is a natural product from shark liver oil and a non-antigenic adjuvant.

Cyclosporin A is a naturally occurring cyclic polypeptide that is the active metabolite of a fungus. Cyclosporin A is an immunosuppressant that binds to procyclins and inhibits calcineurin (IC50=7 nM).

Tauroursodeoxycholate (UR 906), also known as ursodoxicoltaurine, is a highly hydrophilic tertiary bile acid that is produced in humans at a low concentration. Tauroursodeoxycholate is the more hydrophilic form of ursodeoxycholic acid, which is the more abundant naturally produced bile acid in humans.Tauroursodeoxycholate is being investigated for use in several conditions such as Primary Biliary Cirrhosis (PBC), insulin resistance, amyloidosis, Cystic Fibrosis, Cholestasis, and Amyotrophic Lateral Sclerosis.

Prostaglandin E2 (PGE2) is a naturally occurring hormone involved in various physiological processes, such as smooth muscle contraction and relaxation, vasodilation and constriction, blood pressure regulation, and inflammatory regulation.

Arachidonic acid (Immunocytophyte) is an unsaturated, essential fatty acid. It is found in animal and human fat as well as in the liver, brain, and glandular organs, and is a constituent of animal phosphatides. It is formed by the synthesis from dietary linoleic acid and is a precursor in the biosynthesis of prostaglandins, thromboxanes, and leukotrienes.

Docosahexaenoic Acid (DHA) is an essential omega-3 fatty acid prevalent in the brain and retina.

Ursodeoxycholic acid sodium (Sodium Ursodeoxycholate) is a naturally occurring secondary bile acid with anti-inflammatory and cytoprotective activities. Ursodeoxycholic acid sodium acts as signaling molecule, exerting its effects by interacting with bile acid activated receptors,

Cis-N-Feruloyltyramine is a naturally occurring compound found in various plants that shows cytotoxicity against the P-388 cancer cell line. Cis-N-Feruloyltyramine is an inhibitor of in vitro prostaglandin (PG) synthesis.

Coenzyme Q10 (CoQ10) (ubiquinone) is a naturally occurring compound, acting as the electron carrier in the mitochondrial respiratory chain.

Hyaluronidase (Hyaluronate 4-glycanohydrolase), a naturally occurring enzyme, depolymerizes hyaluronic acid through glycosidic bond cleavage and is utilized in ophthalmic surgery.

Perillyl Alcohol is a naturally occurring monoterpene related to limonene with antineoplastic activity. Perillyl alcohol (Isocarveol) inhibits farnesyl transferase and geranylgeranyl transferase, thereby preventing post-translational protein farnesylation and isoprenylation and activation of oncoproteins such as p21-ras, and arresting tumor cells in the G1 phase of the cell cycle.

Emodin (Frangula emodin) is a naturally occurring anthraquinone present in the roots and barks of numerous plants; exerts antiproliferative effects in Y cells that are regulated by different signaling pathways.

Biotin (Vitamin H) is a water-soluble B-vitamin and is necessary for cell growth, the production of fatty acids, and the metabolism of fats and amino acids.

D-Sorbitol (Sorbitol) is a polyhydric alcohol with about half the sweetness of sucrose, occurring naturally and also produced synthetically from glucose. Formerly used as a diuretic, it may still be used as a laxative and in irrigating solutions for certain surgical procedures. It is also utilized in various manufacturing processes, as a pharmaceutical aid, and in several research applications.

p-Hydroxymandelic acid (4-Hydroxymandelic acid) is an acidic metabolite of p-octopamine and p-synephrine (p-phenylephrine). It is also a naturally occurring metabolite of tyramine.

Dopamine hydrochloride (ASL279), a naturally occurring catecholamine formed by decarboxylation of dihydroxyphenylalanine and a precursor of norepinephrine and epinephrine, binds to alpha-1- and beta-1- adrenergic receptors.

Spinosad is a naturally-occurring insecticide found in the the soil bacterium S. spinosa. It is a mixture of the macrocyclic lactones spinosyn A and spinosyn D, which act as agonists of insect nicotinic acetylcholinesterase receptors (nAChRs).

Hypoxanthine (Purin-6-ol), also known as purine-6-ol or Hyp. Hypoxanthine is a naturally occurring purine derivative and a reaction intermediate in the metabolism of adenosine and in the formation of nucleic acids by the nucleotide salvage pathway. Under normal circumstances hypoxanthine is readily converted to uric acid.hypoxanthine is first oxidized to xanthine, which is further oxidized to uric acid by xanthine oxidase.

Biochanin A (4-Methylgenistein) is an isoflavone derivative isolated from red clover Trifolium pratense with anticarcinogenic properties. Biochanin A is a naturally occurring fatty acid amide hydrolase (FAAH) inhibitor.

2-Hydroxy-3-methylbutyric acid is a structural analog of GHB, a naturally occurring substance found in the central nervous system, and a nootropic.

Tetrandrine (Sinomenine A) is a naturally occurring biphenylisoquinoline alkaloid, a calcium channel inhibitor. Tetrandrine inhibits voltage-gated calcium channels (ICa) and Ca2+-activated potassium channels.

DL-Adrenaline Hydrochloride is the hydrochloride salt of the naturally occurring sympathomimetic amine with vasoconstricting, intraocular pressure-reducing activities.

Isovaleric acid (Delphinic acid) is a naturally occurring aroma compound found in Bartlett pear brandies, vanilla beans, rape-honey, and banana.

Spermidine (N-(3-Aminopropyl)-1,4-diaminobutane) inhibits NOS1 (nNOS). Spermidine binds and precipitates DNA and may be used for purification of DNA binding proteins. Spermidine activates PNK (polynucleotide kinase T4). Spermidine binds to and activates NMDA and has been shown to potentiate NMDA-induced currents in a concentration-dependent manner.
