Effect of aromatase inhibitor on oestrogen production in rabbit blastocysts.
J T Wu et al.
Journal of reproduction and fertility, 66(2), 655-662 (1982-11-01)
Aromatase enzyme catalysis is involved in the potent inhibition of estrogen biosynthesis caused by 4-acetoxy- and 4-hydroxy-4-androstene-3, 17-dione.
D F Covey et al.
Molecular pharmacology, 21(1), 173-180 (1982-01-01)

Cancer research, 42(8 Suppl), 3312s-3314s (1982-08-01)
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 indicate that these compounds cause rapid competitive inhibition of the enzyme. Aminoglutethimide binds
M Motta et al.
Journal of steroid biochemistry, 25(4), 593-600 (1986-10-01)
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 the in vitro metabolism of labelled testosterone (T), dihydrotestosterone (DHT) and androstenedione (delta-4-A)
J T Wu
Journal of reproduction and fertility, 72(2), 345-349 (1984-11-01)
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 mg 1,4,6-androstatriene-3,17-dione (ATD) or
