Destruxin B, isolated from entomopathogenic fungus Metarhizium anisopliae , is one of the cyclodepsipeptides with insecticidal and anticancer activities. Destruxin B induces apoptosis via a Bcl-2 Family -dependent mitochondrial pathway in human nonsmall cell lung cancer cells [1] . Destruxin B significantly activates caspase-3 and reduces tumor cell proliferation through caspase-mediated apoptosis , not only in vitro but also in vivo [2] .

Destruxin B (1-30 μM; 48 hours) inhibits cell proliferation of H1299 cells and A549 cells, with IC
50
s of 4.1 μM and 4.9 μM, respectively
[1]
.
Activation of mitochondria-dependent caspase cascade plays an important role in Destruxin B (1-30 μM; 48 hours) induced apoptotic cell death in A549 cells
[1]
.
Destruxin B (1.25-20.00 μM; 72 hours) treatment significantly inhibits HT-29 human colorectal cancer cells viability in time- and dose-dependent manners
[2]
.
Destruxin B (10 or 20 μM; 12 and 24 hours) treatment markedly increases levels of the proapoptotic protein PUMA and reduces levels of antiapoptotic proteins Mcl-1 of A549 cells in a concentration- and time-dependent manner
