Cytochalasin A is a cell-permeable fungal toxin and is an oxidized derivative of cytochalasin B. Cytochalasin A is an inhibitor of HIV-1 protease (IC50 = 3 μM), inhibits actin polymerization and interferes with microtubule assembly by reacting with sulfhy
Cytochalasin C is a cell-permeable fungal toxin that can induce the formation of nuclear sticks. Cytochalasin C is 10 times less toxic than cytochalasin D in mice.
Cytochalasin E is a potent actin depolymerization agent and an epoxide containing Aspergillus-derived fungal metabolite. Cytochalasin E also inhibits angiogenesis and tumor growth. It binds and caps the barbed end of actin filaments to prevent actin elong
Cytochalasin H ((16-Benzyl-5,12-dihydroxy-5,7,14-trimethyl-13-methylidene-18-oxo-17-azatricyclo[9.7.0.01,15]octadeca-3,9-dien-2-yl) acetate) 是肌动蛋白掺入细丝的有效抑制剂。
Cytochalasin B is a mycotoxin binding to the barbed end of actin filaments. It can disrupt the formation of actin polymers (Kd: 1.4-2.2 nM for F-actin).
