thiq thiq thiq is a drug used in scientific research, which is the first non-peptide agonist developed that is selective for the melanocortin receptor subtype mc4. in animal studies, thiq stimulated sexual activity in rats, but with little effect on appetite or inflammation. this supports possible application of mc4 selective agonists for the treatment of sexual dysfunction in humans, although thiq itself has poor oral bioavailability and a short duration of action so improved analogues will need to be developed. thiqidentifiers iupac name n--(1r)-1-(4-chlorobenzyl) -2--2-oxoethylamine cas number312637-48-2 ypubchem cid9938402iuphar/bps1338chemspider8114027comptox dashboard (epa)dtxsid00953320 chemical and physical dataformulac33h41cln6o2molar mass589.169 g·mol−13d model (jsmol)interactive image smiles c1ccc(cc1)c2(ccn(cc2)c(=o)(cc3=cc=c(c=c3)cl)nc(=o)4cc5=cc=cc=c5cn4)cn6c=nc=n6 inchi inchi=1s/c33h41cln6o2/c34-28-12-10-24(11-13-28)18-30(38-31(41)29-19-25-6-4-5-7-26(25)20-36-29)32(42)39-16-14-33(15-17-39,21-40-23-35-22-37-40)27-8-2-1-3-9-27/h4-7,10-13,22-23,27,29-30,36h,1-3,8-9,14-21h2,(h,38,41)/t29-,30-/m1/s1key:hlchesomjvgdsj-loyhvipdsa-n (verify)
