The effect of 1,2,3-triazole instead of 1,2,4-triazole has been examined in the letrozole structure. [31] It has shown that the position of the nitrogen atom in either position 3 or 4 of the 1,2,4 triazole is important for good inhibition of aromatase.
α-Naphthoflavone, also known as 7,8-benzoflavone and 2-phenyl-benzo[h]chromen-4-one, is a synthetic [1] [2] flavone derivative. It can be prepared from 2-naphthol and cinnamaldehyde. [3] α-Naphthoflavone is a potent inhibitor of the enzyme aromatase, the enzyme that converts testosterone to estrogen.
Aromatase inhibitors (AIs) are a class of drugs used in the treatment of breast cancer in postmenopausal women and in men, [1] [2] and gynecomastia in men. They may also be used off-label to reduce estrogen conversion when supplementing testosterone exogenously. They may also be used for chemoprevention in women at high risk for breast cancer.
Letrozole, sold under the brand name Femara among others, is an aromatase inhibitor medication that is used in the treatment of breast cancer for post-menopausal women. [1]It was patented in 1986 and approved for medical use in 1996. [4]

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 .
Exemestane is known chemically as 6-methylideneandrosta-1,4-diene-3,17-dione. Like the aromatase inhibitors formestane and atamestane, exemestane is a steroid that is structurally similar to 4-androstenedione, the natural substrate of aromatase. It is distinguished from the natural substance only by the methylidene group in position 6 and an ...
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]
