1,4,6-Androstatriene-3,17-dione (ATD) is a potent irreversible aromatase inhibitor that inhibits estrogen biosynthesis by permanently binding and inactivating aromatase in adipose and peripheral tissue. [1] It is used to control estrogen synthesis. [2]
[13] [6] The medication was one of the first adrenal steroidogenesis inhibitors as well as the first aromatase inhibitor to be discovered and used clinically, and led to the development of other aromatase inhibitors. [18] [4] [30] [9] Along with testolactone, it is described as a "first-generation" aromatase inhibitor. [7]
Ovarian stimulation with the aromatase inhibitor letrozole has been proposed for ovulation induction in order to treat unexplained female infertility. In a multi-center study funded by the National Institute of Child Health and Development, ovarian stimulation with letrozole resulted in a significantly lower frequency of multiple gestation (i.e., twins or triplets) but also a lower frequency ...
Aromatase (EC 1.14.14.14), also called estrogen synthetase or estrogen synthase, is an enzyme responsible for a key step in the biosynthesis of estrogens.It is CYP19A1, a member of the cytochrome P450 superfamily, which are monooxygenases that catalyze many reactions involved in steroidogenesis.
Known in the field of prohormones Patrick Arnold (the one who introduced 1-AD and the first prohormones) is currently working on ursolic acid, on the other hand in Eastern Europe manufacturers launch supplements based on buteins, [11] - natural compounds considered as the strongest aromatase inhibitors.

Chemical structure of the endogenous androstenedione. In the human body, the enzyme aromatase converts androstenedione to estrogen. Aromatase is an enzyme that belongs to the cytochrome P450 family located on chromosome 15. In the human body, the aromatase consists of 10 β-strands (1 major sheet and 3 minor sheets) and 12 α-helixes.
Letrozole is an orally active, nonsteroidal, selective aromatase inhibitor and hence an antiestrogen. It prevents aromatase from producing estrogens by competitive, reversible binding to the heme of its cytochrome P450 unit. The action is specific, and letrozole does not reduce production of corticosteroids. [citation needed
