cytochalasin d

Cytochalasin D is an actin inhibitor, the removal of actin stress fibers is crucial for the chondrogenic differentiation. It may be an inhibitor of some fertilization processes such as sperm penetration or sperm head decondensation. Cytochalasin D inhibit

19,20-Epoxycytochalasin D is a fungal metabolite that has been found in the endophytic fungus Nemania sp. UM10M. It is active against the chloroquine-sensitive and -resistant strains of P. falciparum (MIC = 0.4 ng/ml for both) without inducing cytotoxicity in Vero cells. It is cytotoxic to BT-549, LLC-PK11, and P388 cells (IC50s = 7.84, 8.4, and 0.16 µM, respectively) but not SK-MEL, KB, or SKOV3 cells up to a concentration of 10 µM.

Cytochalasin C, a cell-permeable fungal toxin, induces the formation of nuclear sticks and is 10 times less toxic than cytochalasin D in mice.
