Abyssinones and related flavonoids as potential steroidogenesis modulators

Abyssinones and related flavonoids were screened against 3 enzymes (3βHSD, 17βHSD and Aromatase) of steroidogenesis pathway. The virtual screening experiment shows high affinity for flavonones than their respective chalcones. A 4'' ­OH blocked prenylated flavonone 2b (2­(2'', 2''­dimethyl chroman­6''­yl)­7­hydroxy chroman­4­one) had consistent binding affinity to all the three enzymes used in this study showing higher binding affinity to aromatase. A good correlation was observed between cytotoxic data (MCF­7, breast cancer cell line) and docking results indicating flavonone as a better steroidogenesis modulator in hormone dependent cancer.
