描述：

JNJ-38877605是一种ATP竞争性的c-Met抑制剂，IC50为4 nM，作用于c-Met比作用于200种其他酪氨酸和丝-苏氨酸激酶选择性高600倍。JNJ-38877605是小分子ATP竞争性c-Met抑制剂，IC50为4 nM。而且, JNJ-38877605作用于c-Met选择性比作用于其他200多种不同酪氨酸和丝苏氨酸激酶高600多倍，也有效抑制HGF刺激的和组成型激活的c-Met磷酸化。 JNJ-38877605按 500 nM 剂量作用于EBC1,GTL16,NCI-H1993,和MKN45细胞，明显降低Met和 RON磷酸化,是侵袭性生长中另外一种关键因素。

溶解性：DMSO ：35 mg/mL (92.8 mM)

体外研究：

JNJ-38877605 shows more than 600-fold selectivity for c-Met compared with more than 200 other diverse tyrosine and serine-threonine kinases and also potently inhibits HGF-stimulated and constitutively activated c-Met phosphorylation in vitro. In EBC1, GTL16, NCI-H1993, and MKN45 cells, JNJ-38877605 (500 nM) leads to a significant reduction of phosphorylation of Met and RON, another key player in invasive growth. A recent study shows that JNJ-38877605 is involved in modulating secretion of IL-8, GROa, uPAR and IL-6 in GTL16 cells.

体内研究：In mice bearing established GTL16 xenografts, JNJ-38877605, dosed orally with 40 mg/kg/day for 72 hours, results in a statistically significant decrease in the plasma levels of human IL-8 (from 0.150 ng/mL to 0.050 ng/mL) and GROα (from 0.080 ng/mL to 0.030 ng/mL). While concentrations of uPAR in the blood become reduced to more than 50% at the same dose.
