Synthesis and estrogen receptor selectivity of 1,1-bis(4-hydroxyphenyl)-2-(p-halophenyl)ethylenes
Ruenitz,Bagley,Nanavati
, p. 1471 - 1475 (1988)
A series of triarylethylenes (1a-e) were synthesized and evaluated for their ability to compete with [3H]estradiol for high-affinity estrogen receptors (ER) in immature rat uterine cytosol. All compounds showed affinity comparable to that of es
