Allenolic acid, or allenoic acid, is a synthetic,[1] nonsteroidal estrogen discovered in 1947 or 1948 that, although studied clinically,[2] was never marketed.[3][4][5] It is an open-ring or seco-analogue of steroidal estrogens like estrone and equilenin.[6][7][8] The compound was named after Edgar Allen, one of the pioneers in estrogen research.[9][10] Although described as an estrogen, allenolic acid probably is totally inactive at the receptor, whereas a derivative, allenestrol (α,α-dimethyl-β-ethylallenolic acid), is reported to be a potent estrogen.[11] Another derivative of allenolic acid (specifically 6-methoxy-allenestrol), methallenestril (brand name Vallestril), is also a potent estrogen and, in contrast to allenolic acid and allenestrol, has been marketed.[12][13][14][15]
