Effects of 4-nitroestrone 3-methyl ether on dimethylbenz(a)anthracene-induced mammary tumors.

4-Nitroestrone 3-methyl ether has been shown to be an effective growth inhibitor of certain dimethylbenz(a)anthracene-induced rat mammary tumors in intact or ovariectomized rats. When administered at optimum levels (24 mg/kg daily), this A-ring-substituted estrone displayed no toxicity, slight estrogenicity, and an antitumor activity which was comparable to that of tamoxifen and nafoxidine and was surpassed only by ovariectomy or pharmacological doses of 17 beta-estradiol 3-benzoate. In addition, the appearance of mammary tumors was prevented when this estrogen derivative was administered to rats just prior to or after dimethylbenz(a)anthracene intubation. Unique to the action of the methyl ether of 4-nitroestrone on mammary tumors was the destruction of adenocarcinomas while permitting the appearance of fibroadenomas. Systemically, 4-nitroestrone 3-methyl ether brought about focal atrophy within the pituitary and ovaries while causing moderate hypertrophy of the uterus. Plasma prolactin was unaffected.[1]
