     Tivantinib (ARQ 197)是一種口服、非三磷酸腺苷競爭性、選擇性、小分子met原癌基因(c-MET)抑制劑。計算出的tivantinib抑制重組人c-MET的抑制常數(shù)(Ki)約為355 nmol/L c-MET是一種受體酪氨酸激酶，是肝細胞生長因子(HGF)的高親和力受體。HGF/c-MET信號通路失調經(jīng)常發(fā)生在人類癌癥中[1]。

     Tivantinib對VEGF受體-3 (Flt4)、p21活化激酶3、鈣調素依賴性激酶ⅱδ和Pim-1有微弱的抑制作用[1]。Tivantinib對多種人類腫瘤細胞系表現(xiàn)出細胞毒性活性，EC50范圍為300-600 nmol/L [4]。值得注意的是，A549、H3122、PC9 (Del E746_A750)、PC9 GR4 (Del E746_A750/T790M)、HCC827、HCC827 GR6、H1993和EBC-1細胞系顯示出對替伐替尼一定程度的敏感性，IC50s在0.36和0.8微米之間[5]。在腫瘤細胞系中，GTL-16、MKN-45、Hs746T、SNU-5、EBC-1、H1993、NCI-H441、A549、HCT-116、U87-MG、A2780和TOV-112D，tivantinib不依賴于c-MET基因擴增和MET蛋白表達而無差別地抑制細胞增殖，EC50范圍為60至600 nmol/L。進一步的研究表明，tivantinib促進有絲分裂停滯，防止細胞重新進入G1，并驅動。

     Tivantinib已在多種人類腫瘤細胞系和人類肺癌、結腸癌、前列腺癌、胰腺癌和乳腺癌的異種移植模型中顯示出抗腫瘤活性[1] [2] [3]。雌性4周齡無胸腺裸(nu/nu)小鼠用作實驗動物。從細胞注射后14至21天開始，與對照組相比，120 mg/kg劑量的Tivantinib顯著抑制了治療動物骨中的腫瘤負荷。增加tivantinib的劑量可減少溶骨性病變的數(shù)量和范圍[6]。
