Common Name3-benzyl-1,6,12-trihydroxy-4,10,12-trimethyl-5-methylidene-3h,3ah,4h,6h,6ah,9h,10h,11h,15h-cycloundeca[d]isoindol-15-yl acetate
DescriptionCytochalasin H belongs to the class of organic compounds known as cytochalasans. These are fungal metabolites structurally characterized by the presence of an isoindolone nucleus fused to a macrocyclic ring, which can either a lactone, as in cytochalasin B, a carbonate, as in cytochalasin E, or a carbocycle, as in cytochalasin D, H, and K. Cytochalasin H is an extremely weak basic (essentially neutral) compound (based on its pKa). Once bound, cytochalasin essentially caps the end of the new actin filament. By blocking the polymerization and elongation of actin, cytochalasins can change cellular morphology, inhibit cellular processes such as cell division, and cause cells to undergo apoptosis. Cytochalasin H is a potentially toxic compound. As a result, they can change cellular morphology, inhibit cellular processes such as cell division, and cause cells to undergo apoptosis. It also regulates plant growth and has shown CNS activity. Anticoagulant therapy with intravenous heparin is also recommended. Some cytochalasins have been shown to have developmental effects. Cytochalasin H is has been isolated from the fungus Phomopsis paspali. Cytochalasins are mycotoxins that have the ability to bind to actin filaments and block polymerization and the elongation of actin. Major biological effects of cytochalasins include inhibition of the division of cytoplasm, reversible inhibition of cell movement, induction of nuclear extrusion, inhibition of such processes as phagocytosis, platelet aggregation and clot retraction, glucose transport, thyroid secretion, and release of growth hormone. Cytochalasins also have the ability to permeate cell membranes, prevent cellular translocation, cause cells to enucleate, and affect other aspects of biological processes unrelated to actin polymerization. 3-benzyl-1,6,12-trihydroxy-4,10,12-trimethyl-5-methylidene-3h,3ah,4h,6h,6ah,9h,10h,11h,15h-cycloundeca[d]isoindol-15-yl acetate is found in Phaeohelotium epiphyllum. One cytochalasin will bind to one actin filament.
