OHPC, also known as 17α-hydroxyprogesterone<unk>  or as 17α-hydroxypregn-4-ene-3,20-dione 17α-hexanoate, is a synthetic pregnane steroid and a derivative of progesterone. It is specifically a derivative of 17α-hydroxyprogesterone with a hexanoate<unk>  ester at the C17α position. Analogues of OHPC include other 17α-hydroxyprogesterone derivatives such as algestone acetophenide (dihydroxyprogesterone acetophenide), chlormadinone acetate, cyproterone acetate, hydroxyprogesterone acetate, hydroxyprogesterone heptanoate, medroxyprogesterone acetate, and megestrol acetate, as well as the<unk>  esters chlormadinone<unk> , gestonorone<unk>  (norhydroxyprogesterone<unk> , medroxyprogesterone<unk> , megestrol<unk> , and methenmadinone<unk> . Synthesis Chemical syntheses of OHPC have been described.
