Aromatase inhibitors and the treatment of breast cancer.
J. Steroid Biochem. 24 , 91, (1986) Inhibition of aromatase to reduce estrogen production by peripheral and ovarian tissue could be a useful approach to treating hormone-dependent breast cancer. Several C19, 17 keto steroids have been identified as aromatase inhibitors. The most potent of these... |

Overview of recent development of aromatase inhibitors.
Cancer Res. 42(8 Suppl) , 3312s-3314s, (1982) Since the first publication in 1973 concerning aromatase inhibitors, several effective compounds have been reported by a number of investigators. Our studies with 4-hydroxyandrostene-3,17-dione, 4-acetoxyandrostene-3,17-dione, and 1,-4,6-androstatrienedione i... |

Effects of aromatase inhibitor 4-hydroxyandrostenedione and other compounds in the 7, 12-dimethylbenz(a)anthracene-induced breast carcinoma model.
Cancer Res. 42(8 Suppl) , 3360s-3364s, (1982) Aromatase inhibitor, 4-hydroxyandrostene-3,17-dione (4-OHA), is a highly effective treatment in rats with 7,12-dimethylbenz(a) anthracene-induced hormone-dependent mammary tumors. Over 90% of tumors regress to less than one-half of their original size, and a ... |

Effect of 1,4,6-androstatriene-3,17-dione (ATD), 4-hydroxy-4-androstene-3,17-dione (4-OH-A) and 4-acetoxy-4-androstene-3,17-dione (4-Ac-A) on the 5 alpha-reduction of androgens in the rat prostate.
J. Steroid Biochem. 25(4) , 593-600, (1986) The present study reports the effects exerted by 1,4,6-androstatriene-3,17-dione (ATD), 4-hydroxy-4-androstene-3,17-dione (4-OH-A) and 4-acetoxy-4-androstene-3,17-dione (4-Ac-A), three steroids known to inhibit the aromatization of androgens to estrogens, on ... |

Inactivation of aromatase in vitro by 4-hydroxy-4-androstene-3,17-dione and 4-acetoxy-4-androstene-3,17-dione and sustained effects in vivo.
Steroids 38(6) , 693-702, (1981) 4-Hydroxy-4-androstene-3,17-dione (4-OHA) and 4-acetoxy-4-androstene-3,17-dione (4-AcA), in addition to being competitive inhibitors of aromatase, cause time-dependent, irreversible, loss of enzyme activity in both human placental and rat ovarian microsomes. ... |

Induction of implantation by aromatase inhibitors in ovariectomized mice.
J. Reprod. Fertil. 72(2) , 345-9, (1984) The ability of aromatase inhibitors to induce implantation in mice was tested in animals in which implantation was delayed by ovariectomy and progesterone treatment. Implantation was consistently induced by 7 mg 4-hydroxyandrostene-3,17-dione (4-OH-A), 7 X 5 ... |
