Abstract
A series of nonsteroidal, side-chain functionalized estrogens based on (3R*,4S*)-3,4-bis(4-hydroxyphenyl)hexane (hexestrol) and (2R*,3S*)-2,3-bis(4-hydroxyphenyl)pentane (norhexestrol) was prepared; thse include amide, diazo ketone, ester, alcohol, ketone, fluoro, bromo, iodo and saturated hydrocarbon derivatives. Analysis of the binding affinity of these compounds to the lamb uterine estrogen receptor, measured by competitive binding assay, reveals trends that can be related to the steric size, the hydrophobicity, and the hydrogen bond accepting character of the side-chain substituents. Comparison of binding affinities between norhexestrol and hexestrol derivatives indicates that, in general, the norhexestrols show significantly higher receptor binding affinities, making this series of compounds ideally suited as functional probes for the estrogen receptor.This publication has 10 references indexed in Scilit:
