Description
The cytochalasins are cell-
permeable fungal metabolites which inhibit actin polymerization. This interferes with such diverse processes as cell movement, growth, phagocytosis, degranulation, and secretion. Cytochalasin E is an epoxide-
containing analog of cytochalasin B which potently and selectively inhibits the growth of endothelial cells (IC
50 < 1 nM), impairing angiogenesis and tumor growth. This cytochalasin does not inhibit glucose transport or HIV-
1 protease activity.
Chemical Properties
white powder
Uses
Cytochalasin E has been used as:
- a toxin to study its effects on avocado plants
- a component of the incubating medium in feline junctional adhesion molecule 1 (fJAM-1) expression assay
- an inhibitor of actin polymerization to study its effects on mitochondria uptake by mice endothelial cells
Uses
Cytochalasin E is a fungal metabolite which has been shown to exhibit antimicrobial and antibacterial effects. Cytochalasin E is a microfilament inhibitor enhancing the low-affinity Fc epsilon receptor (CD23) expression.
Uses
Cytochalasin E is one of a family of potent mycotoxins produced by a range of fungi. All members of the class exhibit profound effects on cytoskeletal proteins, resulting in pronounced morphogenic changes in animals and plants. Despite the common mode of action, there is evidence that individual members display diverse selectivity. Specifically, cytochalasin E acts as an angiogenesis inhibitor and, unlike other cytochalasins, does not inhibit glucose transport.

ChEBI: A natural product found in Arthrinium sacchari.
Biochem/physiol Actions
Cytochalasin E is an epoxide that exhibits anti-proliferative activity in endothelial cells in vitro. It also participates in inhibiting tumor growth and angiogenesis in vivo. Cytochalasin E also possesses antimicrobial and antiviral properties.
