Biological Context

Neobavaisoflavone is a natural isoflavone that was first isolated from seeds of P. corylifolia, which are used in traditional herbal medicine to treat various skin diseases. Neobavaisoflavone has been found to have diverse effects in isolated mammalian cells, including inhibiting DNA polymerase and carboxylesterase 1 (Ki = 5.3 µM).1,2 It also displays antibiotic activity against Gram-negative multidrug resistant bacteria.3
