Mammary tumor inhibiting effect of 3,3'-diacetoxy-.alpha.,.beta.-dialkylstilbenes and of related stilbene oxides
摘要:
3,3'-Diacetoxy-alpha, beta-dialkylstilbenes (alkyl = CH3 to C4H9, 1-4) 3,3'-dihydroxy-alpha, beta-diethylstilbene (5), and their corresponding stilbene oxides (6-10) were synthesized. Compounds 1-10 competitively antagonized in vitro the interaction of [3H]estradiol with its receptor. 3,3'-Diacetoxy-alpha, beta-diethylstilbene (2), 3,3'-diacetoxy-alpha, beta-diethylstilbene oxide (7), and their phenolic analogues (5 and 10) were most effective. Shortening or lengthening the alkyl side chains led to a decrease in receptor affinity. Among the stilbenes and epoxides, those with C2H5 and C3H7 groups (2, 3, 5 and 7, 8, 10) caused the strongest inhibition of the growth of a hormone-dependent postmenopausal human mammary carcinoma serially implanted in nude mice. The strong antitumor activity of 5 and 10 was confirmed by experiments on the 9,10-dimethyl-1,2-benzanthracene-induced, hormone-dependent mammary carcinoma of the Sprague-Dawley rat.
