Lenvatinib是一种多靶点抑制剂，无细胞试验中，作用于VEGFR2(KDR)/VEGFR3(Flt-4)最有效，IC50为4 nM/5.2 nM，对VEGFR1/Flt-1作用效果稍弱，作用于VEGFR2/3比作用于FGFR1， PDGFRα/β选择性高10倍左右。Lenvatinib (E7080) 也是FGFR1-4、PDGFR、Kit (c-Kit)和RET (c-RET)的抑制剂，并具有强效的抗肿瘤活性。Phase 3。

| 体内研究 | Lenvatinib (E7080) (100 mg/kg, p.o.) significantly inhibits local tumor growth at the m.f.p., and at the end of treatment, Lenvatinib mesylate also significantly inhibits metastasis to both regional lymph nodes and distant lung. Lenvatinib (E7080) inhibits the growth of H146 tumor at 30 and 100 mg/kg (BID, QDx21) in a dose-dependent manner and causes tumor regression at 100 mg/kg in H146 xenograft model. IHC analysis with anti-CD31 antibody shows that lenvatinib at 100 mg/kg decreases microvessel density more than anti-VEGF antibody and STI571 treatment. |
| 体外研究 | Lenvatinib (E7080) has IC50s of 4, 5.2, 22 nM for VEGFR2 (KDR), VEGFR3 (Flt-4), and VEGFR1 (Flt-1), respectively. Lenvatinib inhibits PDGFRα, PDGFRβ, FGFR1, and KIT with IC50s of 51, 39, 46, and 100 nM, respectively. |
