Mycalolide B 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 mechanism distinct from that of the cytochalasins. Unlike cytochalasins, it inhibits actin-activated Mg2+-ATPase from rabbit skeletal muscle.
