Mycalolide B (122752-21-0) is a novel marine natural product which binds to actin in a 1:1 molar ratio (Kd=13-20 nM)· It selectively and completely depolymerizes F-actin to G-actin via a novel mechanism different from that of the cytochalasin D· It is a novel and specific inhibitor of actomyosin ATPase
