Lead Optimization Providing a Series of Flavone Derivatives as Potent Nonsteroidal Inhibitors of the Cytochrome P450 Aromatase Enzyme
摘要:
Following our SAR studies on aromatase inhibitors, new compounds were designed by appropriately modifying the structure of flavone 1 using our previously reported CoMFA model. While the introduction of substituents on the 2-phenyl ring alone did not cause improvement in potency, these modifications and the removal of the 7-methoxy group led to compounds showing inhibitory activity in the nanomolar range, comparable to the marketed drug fadrozole.

An attempt was made to synthesise newer 3-methylflavones with various substitution on the ring A and B of 2-phenylchromen-4-one. They were evaluated for antioxidant activity and antibacterial activity against the Gram-positive and Gram-negative bacteria. Five test compounds exhibited DPPH radical scavenging activity with IC50 below 100 mu g/ml, and the same test compounds exhibited 50-100% growth inhibition in Gram-positive bacteria against standard Amoxicillin.

A simple and efficient method for the synthesis of flavones was achieved by selective sulfide Liebeskind-Srogl cross-coupling reaction of 2-(methylthio)-4H-chromen-4-ones and 3-halo-2-(methylthio)-4H-chromen-4-ones with arylboronic acids. This method is the first example of employing Liebeskind-Srogl coupling for the synthesis of flavones. Various aryl groups can be directly installed to the chromone
