PP121 is a multitargeted dual receptor tyrosine kinases inhibitor. PP121 blocks the proliferation of tumor cells by direct inhibition of oncogenic tyrosine kinases and phosphatidylinositol-3-OH kinases. PP-121 is a multi-targeted inhibitor of PDGFR, Hck, mTOR, VEGFR2, Src and Abl with IC50 of 2 nM, 8 nM, 10 nM, 12 nM, 14 nM and 18 nM, also inhibits DNA-PK with IC50 of 60 nM. PP121 blocks the proliferation of tumor cells by direct inhibition of oncogenic tyrosine kinases and phosphatidylinositol-3-OH kinases.

In Vitro Use Guide

PP121 potently and dose-dependently (0.040 to 10 uM) blocked the phosphorylation of Akt, p70S6K and S6 in two glioblastoma cell lines, U87 and LN229. PP-121 at a low concentration of 40 nM inhibits Ret autophosphorylation in TT thyroid carcinoma cells that express the C634W oncogenic Ret mutant 35. PP-121 inhibits cell proliferation with IC50 of 50 nM in TT thyroid carcinoma cells. PP-121 inhibits cell proliferating stimulated only with VEGF with IC50 of 41 nM in human umbilical vein endothelial cells (HUVECs).
