MedKoo CAT#: 565438

CAS#: 36011-19-5

Description: Cytochalasin E is a natural autophagy inhibitor which enhances chemotherapy-induced cell death. Cytochalasin E is an epoxide-containing analog of Cytochalasin B which potently and selectively inhibits the growth of endothelial cells, thereby impairing angiogenesis and tumor growth. Unlike Cytochalasin A and Cytochalasin B, it does not inhibit glucose transport.
