Methallenestril (INN) (brand names Cur-men, Ercostrol, Geklimon, Novestrine, Vallestril), also known as methallenoestril (BAN) and as methallenestrol, as well as Horeau's acid and dimethylethylallenolic acid,^[1][2] is a synthetic, non-steroidal estrogen derived from allenolic acid that was formerly used to treat menstrual issues but is now no longer marketed.^[3][4][5][6] It is a seco-analogue of bisdehydrodoisynolic acid, and although methallenestril is potently estrogenic in rats, in humans it is only weakly so in comparison.^[7] Vallestril was a brand of methallenestril issued by G. D. Searle & Company in the 1950s.^[8]
