| Product Description | 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 Destruxin B significantly activates caspase-3 and reduces tumor cell proliferation through caspase-mediated apoptosis , not only in vitro but also in vivo . In Vitro 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. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Cell Proliferation AssayCell Line: H1299 cells Concentration: 1, 5, 10, 20, 30 μM Incubation Time: 48 hours Result: Inhibited H1299 cells proliferation of H1299 cells with an IC 50 of 4.1 μM. Apoptosis AnalysisCell Line: Lung adenocarcinoma A549 cells Concentration: 1, 5, 10, 20, 30 μM Incubation Time: 48 hours Result: Induces caspase-dependent Lung adenocarcinoma A549 cells death. Cell Viability AssayCell Line: HT-29 human colorectal cancer cells Concentration: 1.25, 2.50, 5.00, 10.00 and 20.00 μM Incubation Time: 72 hours Result: The IC 50 s at 24 h, 48 h and 72h were determined as 14.97, 2.00 and 0.67 μM, respectively. Western Blot AnalysisCell Line: A549 cells Concentration: 10 or 20 μM Incubation Time: 12 and 24 hours Result: Regulates Mcl-1 and PUMA. In Vivo Destruxin B (DB) ( injection; 0.6-15 mg/kg/day for 6 weeks) attenuates the tumor growth in time- and dose-dependent manners. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Animal Model: Athymic female nude mice (BALB/cAnN.Cg-Foxn1nu/CrlNarl), approximately 4-5 weeks old on arrivalDosage: Low dose (0.6 mg/kg), medium dose (3 mg/kg), high dose (15 mg/kg) Administration: Injection; daily; for 6 weeks Result: Low dose, medium dose and high dose indicated a reduction of 23.9%, 33.4% and 55.8% in mean tumor size, respectively. Form:Solid IC50& Target:Bcl-2 Caspase-3 |
