| Description: |
JNJ-38877605 is an ATP-competitive inhibitor of c-Met with IC50 of 4 nM, 600-fold selective for c-Met than 200 other tyrosine and serine-threonine kinases. |
| In Vivo: |
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 [3]. |
| In Vitro: |
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. [1] 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 [2]. A recent study shows that JNJ-38877605 is involved in modulating secretion of IL-8, GROa, uPAR and IL-6 in GTL16 cells [3]. |
