Estrogenic estra-1,3,5(10)-trienes with differential effects on the alpha and beta estrogen receptors, having a linear hydrocarbon chain of from 5-9 carbon atoms in position 11

摘要

Disclosed is a novel class of steroid compounds based on estradiol, and carrying an 11beta-substitution. Said substitution is a hydrocarbon group which may be linear or branched, provided that it comprises, as the longest chain on carbon atom no. 11 of the steroid skeleton, one single linear chain having a length of from 5 to 9 carbon atoms, wherein said chain may be saturated or unsaturated. The resulting compounds have a desirable mixed agonist/antagonist profile for estrogen receptor alpha and estrogen receptor beta.
