Tesevatinib   中文名称: 特伐替尼

Tesevatinib (XL-647) 有效抑制 VEGF、肝配蛋白 RTK 和 EGF/ErbB2 家族。一种可逆 ATP 竞争性抑制剂是 tesevatinib (XL-647)。替塞瓦替尼的靶标是 10 种酪氨酸激酶（例如胰岛素和胰岛素样生长因子 1 受体）和 55 种丝氨酸-苏氨酸激酶（例如细胞周期蛋白依赖性激酶、应激激活蛋白激酶和蛋白激酶 C 亚型） （XL-647）。 Tesevatinib (XL-647) 可灭活 EGFR 通路并阻止携带两种 EGFR 双突变（L858R 和 T790M）的厄洛替尼耐药 H1975 细胞系的细胞分裂。 Tesevatinib (XL-647) 的 IC50 值为 13 nM，会降低 A431 细胞的细胞活力 [1]。

在体内，tesevatinib (XL-647) 对 WT EGFR 表现出强烈且持续的抑制作用。 Tesevatinib (XL-647) 可显着降低肿瘤 EGFR 信号传导、肿瘤血管密度和 H1975 异种移植肿瘤的发展 [1]。

Tesevatinib is a member of the class of quinazolines that is quinazoline substituted by (3,4-dichloro-2-fluorophenyl)amino, methoxy, and [(3aR,5r,6aS)-2-methyloctahydrocyclopenta[c]pyrrol-5-yl]methoxy groups at positions 4, 6 and 7, respectively. It is a multi-target tyrosine kinase inhibitor of EGFR, ErbB2, KDR, Flt4 and EphB4 and exhibits anti-cancer properties. It has a role as an antineoplastic agent, an EC 2.7.10.1 (receptor protein-tyrosine kinase) inhibitor and an epidermal growth factor receptor antagonist. It is a member of quinazolines, an aromatic ether, a member of monofluorobenzenes, a dichlorobenzene, a secondary amino compound, a diether and a tertiary amino compound.
Tesevatinib has been used in trials studying the treatment of Cancer, Stomach Cancer, Brain Metastases, Esophageal Cancer, and Leptomeningeal Metastases, among others. Tesevatinib is a potent inhibitor of multiple RTKs implicated in driving tumor cell proliferation and tumor vascularization (blood vessel formation). Tesevatinib inhibits the EGF, HER2, and VEGF RTKs, each of which is a target of currently approved cancer therapies. In addition, tesevatinib inhibits EphB4, an RTK that is highly expressed in many human tumors and plays a role in promoting angiogenesis. In a broad array of preclinical tumor models including breast, lung, colon and prostate cancer, XL647 demonstrated potent inhibition of tumor growth and causes tumor regression. In cell culture models, tesevatinib retains significant potency against mutant EGFRs that are resistant to current EGFR inhibitors.
Tesevatinib is an orally bioavailable small-molecule receptor tyrosine kinase (RTK) inhibitor with potential antineoplastic activity. Tesevatinib binds to and inhibits several tyrosine receptor kinases that play major roles in tumor cell proliferation and tumor vascularization, including epidermal growth factor receptor (EGFR; ERBB1), epidermal growth factor receptor 2 (HER2; ERBB2), vascular endothelial growth factor receptor (VEGFR), and ephrin B4 (EphB4). This may result in the inhibition of tumor growth and angiogenesis, and tumor regression.

Mechanism of Action
Tesevatinib inhibits the EGF, HER2, and VEGF RTKs, each of which is a target of currently approved cancer therapies. In addition, tesevatinib inhibits EphB4, an RTK that is highly expressed in many human tumors and plays a role in promoting angiogenesis. In a broad array of preclinical tumor models including breast, lung, colon and prostate cancer, XL647 demonstrated potent inhibition of tumor growth and causes tumor regression. In cell culture models, tesevatinib retains significant potency against mutant EGFRs that are resistant to current EGFR inhibitors.
