Midostaurin(pkc412) may suppress tumor growth by inhibiting tumor angiogenesis (via its effects on the VEGF receptor tyrosine kinases) in addition to directly inhibiting tumor cell proliferation (via its effects on PKCs). This anti-angiogenic action may contribute to the antimetastatic and broad antitumor activity displayed by midostaurin(pkc412), as well as the synergy with cytotoxic agents, including doxorubicin, cyclophosphamide, cisplatin and gemcitabine. When given orally, the maximally tolerated dose for midostaurin(pkc412) is >300 mg/kg. [1]

Midostaurin(pkc412) is a broad spectrum protein kinase inhibitor. Midostaurin(pkc412) interacts strongly with ATP binding sites of the conventional PKC-α, -β and -γ, PDGFRβ, VEGF-R2, VEGF-R1 and the cyclin-dependant kinase 1-cyclin B complex. Midostaurin(pkc412) inhibits the growth of various human and animal cell lines in vitro at similar submicromolar concentrations. Midostaurin(pkc412) also effectively inhibits the in vitro proliferation of glioblastoma and induced the accumulation of cells in G2/M and formation of giant nuclei with extensive fragmentation and apoptotic bodies. Midostaurin(pkc412) is able to reverse the p-glycoprotein-mediated multidrug resistance of tumor cells in vitro. [1]

DMSO:8.6 mg/mL (15 mM)

Each well is added with 5 mM WST-1 and 0.2 mM 1-methoxy PMS and the absorbance at 450 nm is measured by a Microplate Reader.(Only for Reference)
