LATRUNCULIN A Chemical Properties,Usage,Production

Description

Actin disruption is used to study cell functions in vitro (e.g., migration, endocytosis) and in vivo (e.g., tumor cell invasion). Latrunculin A is a bioactive 2-thiazolidinone macrolide derived from sponges that sequesters G-actin and prevents F-actin assembly. It binds monomeric actin with 1:1 stoichiometry and can be used to block actin polymerization both in vitro (K_d = 0.2 μM) and in cells (0.5 μM, 30 min).{ Latrunculin A (1-10 μM) causes depolymerization of tumor cell cytoskeleton within ten minutes. Overnight treatment of cells with latrunculin A (10 μM) strongly suppresses actin synthesis. Prolonged cell treatment blocks dexamethasone-induced changes in actin cytoskeleton with no effect on cell viability.

Uses

Latrunculin A, Latrunculia magnifica is a stabilizer of monomeric G-actin and polymerization inhibitor.

Uses

Latrunculin A has been used as medium supplementation for A549 cells to determine the internalization mechanism of CAV9 in A549 human lung carcinoma cells.

Definition

ChEBI: A bicyclic macrolide natural product consisting of a 16-membered bicyclic lactone attached to the rare 2-thiazolidinone moiety. It is obtained from the Red Sea sponge Latrunculia magnifica and from the Fiji Islands sponge Cacospongia myc fijiensis. Latrunculin A inhibits actin polymerisation, microfilament organsation and microfilament-mediated processes.

General Description

Latrunculin A, a toxin extracted from the red sea sponge Latrunculia magnifica. It participates in vitro in the morphological alteration of the polymerization of pure actin. It forms a complex by binding with the nucleotide cleft of actin for actin filaments elongation.

Biochem/physiol Actions

Latrunculin A inhibits actin polymerization by a different mechanism than cytochalasins. Latrunculin A disrupts microfilament-mediated processes.
