Cymegesolate (developmental code name Progestin No. 1), also known as cypionyl megestrol acetate or as megestrol acetate 3β-cypionate, is a progestin medication which was never marketed.[1][2][3][4][5][6] It was developed in China in the late 1970s and early to mid 1980s for use as a hormonal contraceptive.[1][2][3][4][5][6] The medication was formulated at a dose of 50–100 mg in combination with a "trace" dose of 0.25–0.5 mg quinestrol as a long-lasting, once-a-month combined oral contraceptive pill.[1][2] This combination has been studied in 1,213 women across a total of 9,651 menstrual cycles, with contraceptive effectiveness of over 99.13% and "very few side effects."[1] At the high dose (100 mg / 0.5 mg), it showed an anovulation rate of only about 60%, and instead mediated its contraceptive effects via a marked anti-implantation effect.[2]
Chemistry
Cymegesolate, also known as megestrol acetate 3β-cypionate, as well as 17α-acetoxy-6-dehydro-6-methylprogesterone 3β-cyclopentylpropionate or 17α-acetoxy-6-methylpregna-4,6-diene-3,20-dione 3β-cyclopentylpropionate, is a synthetic pregnane steroid and a derivative of progesterone and 17α-hydroxyprogesterone.[1][2] It is the C3β cypionate (cyclopentylpropionate) ester of megestrol acetate.[1][2] A closely related medication is acetomepregenol (mepregenol diacetate; also known as megestrol 3β,17α-diacetate), which, in contrast, has been marketed.[7][8][9][10]
