Abstract:
:Hydroxy-2-phenylindoles carrying substituted benzyl groups and similar substituents at the nitrogen were synthesized and tested for their ability to displace estradiol from its receptor. All of the derivatives tested exhibited high binding affinities for the calf uterine estrogen receptor, with RBA values ranging from 0.55 to 16 (estradiol 100). The mouse uterine weight tested revealed only low estrogenicity for this class of compounds. Several derivatives showed antiestrogenic activity with a maximum inhibition of estrone-stimulated uterine growth of 40%. Two of the compounds (6c, 21c) were tested for antitumor activity in dimethylbenanthracene- (DMBA-) induced estrogen-dependent rat mammary tumors. Only the 4-cyanobenzyl derivative 21c was active. After 4 weeks of treatment with 12 mg/kg (6 times/week), the average tumor area was decreased by 57% (control +204%). In vitro, an inhibitory effect of 21b was only observed with hormone-sensitive MCF-7 breast cancer cells but not with hormone-independent MDA-MB 231 cells. These results make a mode of action involving the estrogen receptor system likely.
