Abstract

3,4-di(3'-hydroxyphenyl)-hexane (I) [68266-24-0], 3,3'-dihydroxy-alpha ,beta -diethylstilbene (II) [80149-87-7], 3,4-epoxy-3,4-di(4'-hydroxyphenyl)-hexane (III) [6052-82-0], and 3,4-epoxy-3,4-di(3'-hydroxyphenyl)-hexane (IV) [80149-95-7] all inhibited DMBA [57-97-6]-induced, hormone-dependent, mammary carcinoma in rats. I was also prophylactic against DMBA induction of mammary carcinoma. estradiol [50-28-2] Antagonized the effect of I on a human breast cancer cell line (MCF-7), indicating that I acts as an antiestrogen in inhibiting mammary tumors. The marked superiority of IV over that of II as an antitumor agent suggests a contribution to the antitumor action of the epoxide group.
