Biological Activity：
Cytochalasin H is used in actin polymerization studies. Cytochalasins are potent mycotoxins which bind to the barbed end of actin filaments resulting in inhibition of both the association and dissociation of subunits. Used as a tool for cytological research. These fungal toxins are related by their chemical structure characterized by a highly substituted hydrogenated isoindole ring to which is fused a macrocyclic ring. In vitro, cytochalasin H exhibits antibacterial, antifungal, nematocidal and antitumor activity.
The cytochalasins are cell-permeable fungal metabolites that inhibit actin polymerization. This interferes with such diverse processes as cell movement, growth, phagocytosis, degranulation, and secretion. Cytochalasin H is a potent inhibitor of actin incorporation into filaments. Like cytochalasin D , it also increases the steady-state diffusion coefficients of filaments, suggesting that it stimulates filament shortening.Cytochalasin H suppresses the production of reactive oxygen species by stimulated human neutrophils, blocks endocytosis of CD59 in lymphocytes, and shows anti-angiogenic activity both in vitro and in vivo.
