Okadaic acid
Okadaic acid is found in mollusks. Okadaic acid is found in the marine sponges Halichondria okadai and Halichondria melanodocia and shellfish. It is a metabolite of Prorocentrum lima. It is a diarrhetic shellfish toxin. Okadaic acid is a toxin that accumulates in bivalves and causes diarrhetic shellfish poisoning. The molecular formula of okadaic acid, which is a derivative of a C38 fatty acid, is C44H68O13. The IUPAC name of okadaic acid is (2R)-2-hydroxy-3-{(2S,5R,6R,8S)-5-hydroxy-[(1R,2E)-3-((2R,5R,6S,8R,8aS)-8-hydroxy-6-{(1S,3S)-1-hydroxy-3-[(3R,6S)-3-methyl-1,7-dioxaspiro[5.5]undec-2-yl]butyl}-7-methyleneoctahydro-3H,3H-spiro[furan-2,2-pyrano[3,2-b]pyran]-5-yl)-1-methylprop-2-en-1-yl]-10-methyl-1,7-dioxaspiro[5.5]undec-10-en-2-yl}-2-methylpropanoic acid. Okadaic acid was named from the marine sponge Halichondria okadai, from which okadaic acid was isolated for the first time. It has also been isolated from another marine sponge, H. malanodocia, as a cytotoxin. The real producer of okadaic acid is a marine dinoflagellate D009676 - Noxae > D011042 - Poisons > D008387 - Marine Toxins D009676 - Noxae > D002273 - Carcinogens D049990 - Membrane Transport Modulators D004791 - Enzyme Inhibitors D007476 - Ionophores
Guanadrel
Guanadrel is a postganglionic sympathetic adrenergic antagonist that is administered orally to treat hypertension (high blood pressure). It was used in the form of its sulfate (trade name: Hylorel) but has been largely superseded by other antihypertensive agents due to its unpleasant side effect of orthostatic hypotension (i.e. dizziness when standing) (PMID: 6143629). Guanadrel both prevents noradrenaline (norepinephrine) release and depletes noradrenaline stores which effectively creates a peripheral sympathetic blockade. This serves to reduce vasoconstriction which subsequently lowers blood pressure (PMID: 3896742). C78274 - Agent Affecting Cardiovascular System > C270 - Antihypertensive Agent D002317 - Cardiovascular Agents > D000959 - Antihypertensive Agents Guanadrel is an orally active postganglionic adrenergic inhibitor of spiroketal. Guanadre can be used in anti-hypertensive studies[1].

4-Deoxy-2,3-dihydromycosinol
4-deoxy-2,3-dihydromycosinol is a member of the class of compounds known as ketals. Ketals are acetals derived from ketones by replacement of the oxo group by two hydrocarbyloxy groups R2C(OR)2 ( R not Hydrogen ). This term, once abandoned, has been reinstated as a subclass of acetals. 4-deoxy-2,3-dihydromycosinol is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). 4-deoxy-2,3-dihydromycosinol can be found in roman camomile, which makes 4-deoxy-2,3-dihydromycosinol a potential biomarker for the consumption of this food product.
