Notes: The cytochalasins are cell-permeable fungal metabolites which inhibit actin polymerization.{21305,21310,21312,21316} This interferes with such diverse processes as cell movement, growth, phagocytosis, degranulation, and secretion.{21307,21313,21306,21315} Cytochalasin A is an oxidized analog of cytochalasin B that uniquely inhibits HIV-1 protease (IC50 = 3 μM).{21311} Cytochalasins A and B differ from other cytochalasins in being able to rapidly and reversibly inhibit glucose transport by competitively binding glucose transporters (Ki = 4.0 and 0.6 μM, respectively).{21309,21308} Cytochalasin A also induces the phosphorylation of the tyrosine phosphatase PTP3 of Dictyostelium, activating STATc.{21304}
