Midostaurin

Midostaurin (pkc412) is a multi-targeted kinase inhibitor, including PKCα/β/γ, Syk, Flk-1, Akt, PKA, c-Kit, c-Fgr, c-Src, FLT3, PDFRβ and VEGFR1/2 with IC50 ranging from 80-500 nM. PKC412 showed a broad antiproliferative activity against various tumor and normal cell lines in vitro, and was able to reverse the Pgp-mediated multidrug resistance of tumor cells in vitro. PKC412 displayed a potent antitumor activity as single agent and was able to potentiate the antitumor activity of some of the clinically used cytotoxins (Taxol and doxorubicin) in vivo. Orally administered PKC412 also strongly inhibited retinal neovascularization as well as laser-induced choroidal neovascularization in murine models.
