CHAETOGLOBOSIN A Usage And Synthesis

Description

Chaetoglobosin A (50335-03-0) is a cytochalasin analog which targets filamentous actin. Displays cytotoxic effects against human colorectal HCT116 cells, IC50=3.15 μM.1 Preferentially induces apoptosis in chronic lymphocytic leukemia cells via targeting the cytoskeleton.2 Enhances the fibrinolytic activity of vascular endothelial cells.3

Occurrence

A complex macrocyclic alkaloid, this base has been isolated from Diplodia rnacrospora. Chaetoglobosin A possesses the property of inhibiting growth in wheat coleoptiles.

Uses

Chaetoglobosin A is a mycotoxic cytochalasan compound.

Definition

ChEBI: A cytochalasan alkaloid isolated from Chaetomium globosum and Calonectria morganii.

storage

+4°C
