Overview

Rhapontigenin is a natural analog of resveratrol with anticancer, antioxidant, antifungal and antibacterial activities. Rhapontigenin is amechanism-based, potent and selective cytochrome P450 1A1 inactivator (IC50  = 400 nM). Rhapontigenin exhibits 400-fold and 23-fold selectivity for P450 1A1 over P450 1A2 and P450 1B1, respectively

• Description: This compound belongs to the class of organic compounds known as stilbenes. These are organic compounds containing a 1,2-diphenylethylene moiety. Stilbenes (C6-C2-C6 ) are derived from the common phenylpropene (C6-C3) skeleton building block. The introduction of one or more hydroxyl groups to a phenyl ring lead to stilbenoids.
