fluoromedroxyprogesterone acetate fluoromedroxyprogesterone acetate fluoromedroxyprogesterone acetate (fmpa, 9α-fluoromedroxyprogesterone acetate, or 9α-fmpa) is a synthetic steroid medication which was under development by meiji dairies corporation in the 1990s and 2000s for the potential treatment of cancers but was never marketed. it is described as an antiangiogenic agent, with about two orders of magnitude greater potency for inhibition of angiogenesis than its parent compound medroxyprogesterone acetate. fmpa showed about the same affinities for the progesterone and glucocorticoid receptors as mpa. it reached the preclinical phase of research prior to the discontinuation of its development. fluoromedroxyprogesterone acetateclinical dataother namesfmpa; 9α-fluoromedroxyprogesterone acetate; 9α-fmpa; 9α-fluoro-6α-methyl-17α-hydroxyprogesterone acetate; 17α-acetoxy-9α-fluoro-6α-methylpregn-4-ene-3,20-dione; 9α-fluoro-6α-methyl-3,20-dioxopregn-4-en-17-yl acetateroutes ofadministrationby mouthdrug classangiogenesis inhibitor; progestogen; progestogen ester; progestin; glucocorticoididentifiers iupac name phenanthren-17-yl] acetate cas number171611-77-1 ypubchem cid9865941chemspider8041632unii8q7rbx3vsuchemical and physical dataformulac24h33fo4molar mass404.522 g·mol−13d model (jsmol)interactive image smiles c1c23cc(3(cc2(4(c1=cc(=o)cc4)c)f)c)(c(=o)c)oc(=o)c inchi inchi=1s/c24h33fo4/c1-14-12-20-18-7-9-24(15(2)26,29-16(3)27)22(18,5)10-11-23(20,25)21(4)8-6-17(28)13-19(14)21/h13-14,18,20h,6-12h2,1-5h3/t14-,18-,20-,21-,22-,23+,24-/m0/s1key:oitytglrwmevsq-xdbmovbssa-n
