     多維替尼(TKI258，CHIR-258)是一種針對(duì)FLT3、KIT、FGFR、VEGFR、PDGFRα和PDGFRβ的多靶點(diǎn)受體酪氨酸激酶抑制劑，其IC50分別為1納米、2納米、8-9納米、8-13納米、210納米和27納米[1]。

     TKI258以150 nM或90 nM的IC50值特異性抑制ZNF198-FGFR1或BCR-FGFR1細(xì)胞的生存力。TKI258以劑量依賴性方式抑制ERK和STAT5基因的磷酸化。TKI258還特異性抑制FGFR1OP2-FGFR1陽(yáng)性KG1和KG1A細(xì)胞系的增殖和存活，增加凋亡水平[2]。在肝細(xì)胞癌(HCC)細(xì)胞中，TKI258和替加珠單抗的組合恢復(fù)了HCC細(xì)胞對(duì)TRAIL和替加珠單抗誘導(dǎo)的凋亡的敏感性。TKI258抑制STAT3的磷酸化，并隨后降低Mcl-1、生存素和Cylcin D1的蛋白水平。TRAIL和TKI258的聯(lián)合治療增加了SHP-1的活性[3]。用TKI258抑制FGFR3降低了waldenstr m巨球蛋白血癥(WM)細(xì)胞存活率，增加了細(xì)胞凋亡，并誘導(dǎo)細(xì)胞周期停滯。TKI258減少WM與骨髓細(xì)胞的相互作用，逆轉(zhuǎn)其增殖。TKI258與其他藥物具有疊加效應(yīng)[4]。

在體內(nèi)，替加珠單抗和TKI258的組合抑制了Huh-7異種移植腫瘤的生長(zhǎng)[3]。TKI258減少了WM腫瘤的進(jìn)展[4]。
