acetoxolutamide acetoxolutamide acetoxolutamide is a nonsteroidal androgen and selective androgen receptor modulator (sarm) which was described in 2000 and was never developed or marketed for medical use. it was derived from structural modification of the nonsteroidal antiandrogen bicalutamide and the nonsteroidal sarm acetothiolutamide. acetoxolutamide shows greatly improved pharmacokinetic properties and anabolic and androgenic potency relative to acetothiolutamide in animals. it is the (2r) enantiomer of andarine (also known as acetamidoxolutamide or androxolutamide). acetoxolutamideclinical datadrug classnonsteroidal androgen; selective androgen receptor modulatoridentifiers iupac name (2r)-3-(4-acetamidophenoxy)-2-hydroxy-2-methyl-n-propanamide cas number885324-25-4pubchem cid10181786chemspider8357288chemblchembl511130comptox dashboard (epa)dtxsid10436497 chemical and physical dataformulac19h18f3n3o6molar mass441.363 g·mol−13d model (jsmol)interactive image smiles cc(=o)nc1=cc=c(c=c1)oc(c)(c(=o)nc2=cc(=c(c=c2)(=o))c(f)(f)f)o inchi inchi=1s/c19h18f3n3o6/c1-11(26)23-12-3-6-14(7-4-12)31-10-18(2,28)17(27)24-13-5-8-16(25(29)30)15(9-13)19(20,21)22/h3-9,28h,10h2,1-2h3,(h,23,26)(h,24,27)/t18-/m1/s1key:yvxvtlgidoacbj-gosisdbhsa-n
