Cytochalasin

Cytochalasins are fungal metabolites that have the ability to bind to actin filaments and block polymerization and the elongation of actin. As a result of the inhibition of actin polymerization, cytochalasins can change cellular morphology, inhibit cellular processes such as cell division, and even cause cells to undergo apoptosis. Cytochalasins h...

cytochalasin

A group of fungal metabolites that inhibit the addition of G actin to a nucleation site and therefore perturb labile microfilament arrays. Cytochalasin B inhibits at around 1 microgram/ml but at about 5 _g/ml begins to inhibit glucose transport. Cytochalasin D affects only the microfilament system and is therefore preferable. ...
