Cytochalasines
WebCytochalasins, a group of chemicals excreted by various molds, block cell movement. The cytochalasins bind to the plus end of microfilaments; block further polymerization; and inhibit cell motility, phagocytosis, microfilament-based trafficking of organelles and vesicles, and the production of lamellipodia and microspikes. WebCytochalasans are a group of fungal-derived natural products characterized by a perhydro-isoindolone core fused with a macrocyclic ring, and they exhibit a high structural diversity and a broad spectrum of bioactivities.
