Description
Aspochalasin D is a co-metabolite originally isolated from
A. microcysticus with aspochalasins A, B, and C, that was initially thought to be inactive. It has antibacterial activity against Gram-positive and Gram-negative bacteria at a concentration of 1 mg/ml. Aspochalasin D is more cytotoxic,
via apoptosis, to Ba/F3-V12 cells in an IL-3-free medium than in an IL-3-containing medium (IC
50s = 0.49 and 1.9 μg/ml, respectively).
