生物活性
Destruxin B 是从昆虫病原真菌中分离的绿僵菌 (Metarhizium anisopliae),是一种具有杀虫和抗癌活性的环肽。 Destruxin B 通过 Bcl-2 家族依赖的线粒体途径在人类非小细胞肺癌细胞中诱导细胞凋亡。Destruxin B 显著激活 caspase-3,并在体外和体内通过 caspase 介导的细胞凋亡减少肿瘤细胞增殖。
体外研究
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.
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.
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.
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 .
