New derivatives, 14α-hydroxy-1-methylandrosta-1,4-diene-3,17-dione ((2) (IC50, 9.7±0.72 nM) of 1 (IC50, 13.8±0.2 nM), and 2-methylandrosta-12β,17β-dihydroxy-1,4-diene-3-one (4) (IC50, 4.23±0.133 nM) of 3 (IC50, 6.4±0.06 nM) showed a potent inhibition against human aromatase enzyme and thus have the potential to treat ER+ breast-cancers and other related diseases. New metabolites, 2α-methyl-9α,17β-dihydroxy-5α-androstan-3-one ((5) (IC50=793.0±29.9 nM) of 3, 6-methylene-3α,7β,17β-trihydroxy-5β-androstane (7) (IC50, 46.1±0.81 nM), and 11α,17β-dihydroxy-6-methylene-androsta-1,4-diene-3-one (8) (IC5O=12797.0±844 nM) of exemestane (6) (IC50=232.0±31 nM) also showed a remarkable anti-aromatase activity. Aromatase is an enzyme, involves in the synthesis of estrogen (ER). Increased amount of ER due to overexpression of aromatase in the body, promotes cancerous cells growth in breast. Therefore, aromatase enzyme is a key target for the discovery of chemotherapeutic agents against ER+ breast-cancers.
