Tyrphostin AG1296 (Tyrphostin AG 1296) is an inhibitor of PDGFR with IC50 of 0.3-0.5 μM, no activity to EGFR.

SKLB610, a novel multi-targeted inhibitor, inhibits angiogenesis-related tyrosine kinase VEGFR2, FGFR2, and PDGFR at a rate of 97%, 65%, and 55%, respectively, at the concentration of 10 μM in biochemical kinase assays.

Amlexanox (AA673) is an anti-aphthous ulcer drug. Amlexanox inhibits the synthesis and release of inflammatory mediators, including leukotrienes and histamine, from mast cells, neutrophils, and mononuclear cells. Amlexanox also acts as a leukotriene D4 antagonist and a phosphodiesterase inhibitor. Amlexanox decreases the time ulcers take to heal as well as the pain associated with the ulcers.

S49076 HCl (S-49076 Hydrochloride) is an effective inhibitor of MET, AXL/MER, and FGFR1/2/3. S49076 HCl potently blocked cellular phosphorylation of MET, AXL, and FGFRs and inhibited downstream signaling in vitro and in vivo. In cell models, S49076 HCl inhibited the proliferation of MET- and FGFR2-dependent gastric cancer cells blocked MET-driven migration of lung carcinoma cells, and inhibited colony formation of hepatocarcinoma cells expressing FGFR1/2 and AXL. In tumor xenograft models, a good pharmacokinetic/pharmacodynamic relationship for MET and FGFR2 inhibition following oral administration of S49076 HCl was established and correlated well with impact on tumor growth.

ZM323881 hydrochloride (ZM 323881 HCl) is a potent and selective VEGFR2 inhibitor.
