phenylacetylrinvanil phenylacetylrinvanil phenylacetylrinvanil (idn-5890) is a synthetic analogue of capsaicin which acts as a potent and selective agonist for the trpv1 receptor, with slightly lower potency than resiniferatoxin, though still around 300 times the potency of capsaicin. it is an amide of vanillylamine and ricinoleic acid, with the hydroxyl group on ricinoleic acid esterified with phenylacetic acid. it is used to study the function of the trpv1 receptor and its downstream actions, and has also shown anti-cancer effects in vitro. phenylacetylrinvanilidentifiers iupac name -18-oxooctadec-9-en-7-yl] 2-phenylacetate cas number849343-53-9pubchem cid25171466chemspider74098843chemical and physical dataformulac34h49no5molar mass551.768 g·mol−13d model (jsmol)interactive image smiles cccccc(c/c=c\cccccccc(=o)ncc1=cc(=c(c=c1)o)oc)oc(=o)cc2=cc=cc=c2 inchi inchi=1s/c34h49no5/c1-3-4-5-15-20-30(40-34(38)26-28-18-13-12-14-19-28)21-16-10-8-6-7-9-11-17-22-33(37)35-27-29-23-24-31(36)32(25-29)39-2/h10,12-14,16,18-19,23-25,30,36h,3-9,11,15,17,20-22,26-27h2,1-2h3,(h,35,37)/b16-10-/t30-/m1/s1key:lxlbuujanysiku-djvrbghssa-n
