  Structure-activity relationship of antiestrogens. Effect of the side chain and its position on activity of 2,3-diaryl-2H-1-benzopyrans

  摘要：

  A series of 2,3-diaryl-2H-1-benzopyrans carrying a tertiary aminoethoxy chain at the ortho, meta, or para position of 2-phenyl or an alkyl at position 4 of the pyran ring were synthesized and evaluated for their affinity for estrogen receptor (ER) and for microsomal antiestrogen specific binding site and for their uterotrophic-antiuterotrophic activities in rodents. The analogues bearing the side chain at the para position of 2-phenyl were found to be active while those substituted at the meta and ortho positions were inactive as ER ligands as well as estrogen agonists-antagonists. Among para-substituted ethers, the 2-piperidinoethoxy analogue 5 was found to be a more effective antiestrogen than the corresponding pyrrolidino, dimethylamino, and related analogues. Incorporation of a methyl or an ethyl at C4 in the pyran nucleus was found to increase receptor affinity of the prototypes. The ethyl was also found to potentiate agonist activity of the prototype while abolishing its antagonist activity. The piperidino analogue 5 was found to be a better antiestrogen than tamoxifen as well as LY-117018 in rats as well as mice. The prototypes were also found to have high affinity for the microsomal antiestrogen specific binding sites. The benzopyrans have thus emerged as a new group of potent antiestrogens.
