Pamufetinib (TAS-115) mesylate is a potent VEGFRand hepatocyte growth factor receptor (c-Met/HGFR)-targeted kinase inhibitor, with IC₅₀s of 30 and 32 nM for rVEGFR2 and rMET, respectively.

IC50: 30 nM (rVEGFR2), 32 nM (rMET)^[1]

Pamufetinib mesylate powerfully suppresses the VEGF-dependent proliferation of HUVECs (IC₅₀=0.019 μM) as a VEGFR-targeted inhibitor and powerfully suppresses the proliferation of MET-amplified cancer cells (GI₅₀=0.032-0.362 μM) as a MET-targeted inhibitor. Pamufetinib mesylate has much less toxicity in various normal cell lines when compared with other VEGFR-targeted kinase inhibitors^[1]. Crizotinib and Pamufetinib mesylate inhibit Met phosphorylation and reverse erlotinib resistance and VEGF production triggered by HGF in PC-9 and HCC827 cells^[2].

Pamufetinib mesylate completely suppresses the progression of MET-inactivated tumor by blocking angiogenesis without toxicity when given every day for 6 weeks, even at a serum-saturating dose of Pamufetinib mesylate. Pamufetinib mesylate induces marked tumor shrinkage and prolonges survival in MET-amplified human cancer–bearing mice^[1].

Tumor cells (8000 cells/800 mL) with or without TAS-115 (1.0 μM) or erlotinib (0.3 μM) in the lower Transwell collagen–coated chambers are cocultured with MRC-5 (1000 cells/300 μL) cells in the upper chamber for 72 hours. The upper chamber is then removed. Cell viability is measured using the MTT assay^[2].

Mice^[1]

The TAS-115 dose levels are set at 12.5, 50, and 200 mg/kg/d. The dose level for sunitinib is set at 40 mg/kg/d. Oral drug treatment is continued for 14 or 42 consecutive days for the chronic dosing in the SC-9 xenograft model. During the treatment period, TV and body weight are measured twice per week. The antitumor efficacy is assessed at the end of each study period^[1].
