Allenolic acid
Chemical compound
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]
