Background:

Benastatin B is a polyketide synthase-derived benastatin that has been found inStreptomycesand has diverse biological activities.^1,2,3It inhibits glutathione S-transferase (GST; K_i= 3.7 µM for the rat liver enzyme).²Benastatin B also inhibits the transglycosylase activity ofA. baumannii,C. difficile,E. coli, andS. aureusrecombinant penicillin-binding proteins (PBPs; IC₅₀s = 16, 53.3, 30.7, and 31.6 µM, respectively).³It is active against several bacteria, including methicillin-resistantS. aureus(MRSA; MIC = 3.12 µg/ml).²
