1,1,2-Triphenylbut-1-enes, which are substituted with acetoxy groups on one, two, or three aromatic rings in the para and/or meta positions, were synthesized.The identity of the occurring E and Z isomers were established by 1H NMR spectroscopy.A study on structure-activity relationships was carried out with regard to estradiol receptor affinity and to inhibiting effects on the growth of a postmenopausal human mammary carcinoma implanted in nude mice.The para-substituted compounds generally exhibited a higher receptor affinity and a better antitumor activity than the corresponding meta-substituted ones.The E isomers were superior to the respective Z isomers in those two properties.The tumor-inhibiting effect of the mono-and disubstituted compounds was better than that of the trisubstituted ones.Except for the trisubstituted compounds, they all showed a good correlation between estradiol receptor affinity and antitumor activity.One of the compounds was also tested on the 9,10-dimethylbenzanthracene-induced, hormone-dependent mammary carcinoma of the Spraque-Dawley rat, and the results corresponded to those obtained in the xenograft tumor.
