Sunitinib ^New

Sunitinib (SU11248) is a multi-targeted RTK inhibitor targeting VEGFR2 (Flk-1) and PDGFRβ with IC50 of 80 nM and 2 nM, and also inhibits c-Kit. Sunitinib is also a dose-dependent inhibitor of the autophosphorylation activity of IRE1α. Sunitinib induces autophagy and apoptosis.

Erlotinib ^New

Erlotinib (CP358774, NSC 718781, OSI-774) is an EGFR inhibitor with IC50 of 2 nM, >1000-fold more sensitive for EGFR than human c-Src or v-Abl. Erlotinib induces autophagy.

Sunitinib Malate

Sunitinib Malate (SU 11248) is a multi-targeted RTK inhibitor targeting VEGFR2 (Flk-1) and PDGFRβ with IC50 of 80 nM and 2 nM in cell-free assays, and also inhibits c-Kit. Sunitinib Malate effectively inhibits autophosphorylation of Ire1α. Sunitinib Malate increases both death receptor and mitochondrial-dependent apoptosis.

CP-673451

CP-673451 is a selective inhibitor of PDGFRα/β with IC50 of 10 nM/1 nM in cell-free assays, exhibits >450-fold selectivity over other angiogenic receptors, has antiangiogenic and antitumor activity.

Imatinib (STI571)

Imatinib (STI571, CGP057148B, Gleevec) is a multi-target inhibitor of tyrosine kinase with inhibition for v-Abl, c-Kit and PDGFR, IC50 values are 0.6 μM, 0.1 μM and 0.1 μM in cell-free or cell-based assays, respectively. Imatinib (STI571) induces autophagy.

PP121

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.

Tyrphostin AG 1296

Tyrphostin AG 1296 is an inhibitor of PDGFR with IC50 of 0.3-0.5 μM, no activity to EGFR. Tyrphostin AG1296 inhibits FGFR and c-Kit with IC50 of 12.3 μM and 1.8 μM in Swiss 3T3 cells. Tyrphostin AG1296 induces dramatic apoptosis in A375R cells.

Sennoside B

Sennoside B, a kind of irritant laxative isolated from rhei rhizome, inhibits PDGF-stimulated cell proliferation.

Gefitinib (ZD1839)

Gefitinib (ZD-1839, Iressa) is an EGFR inhibitor for Tyr1173, Tyr992, Tyr1173 and Tyr992 in the NR6wtEGFR and NR6W cells with IC50 of 37 nM, 37nM, 26 nM and 57 nM, respectively. Gefitinib promotes autophagy and apoptosis of lung cancer cells via blockade of the PI3K/AKT/mTOR pathway.
