c-Met (IC50 = 4 nM)
MET (hepatocyte growth factor receptor). JNJ-38877605 targets c-Met, a receptor tyrosine kinase (RTK) involved in cancer cell survival, invasiveness, and tumor angiogenesis. It functions as a small-molecule, ATP-competitive inhibitor of the c-Met kinase. The compound has an IC50 of 4 nM for c-Met and is 600-fold selective over 200 other tyrosine and serine-threonine kinases. By inhibiting c-Met, JNJ-38877605 disrupts signaling pathways that promote tumor growth and metastasis. |

| ln Vitro |
JNJ-38877605 potently inhibits HGF-stimulated and constitutively activated c-Met phosphorylation in vitro and exhibits more than 600-fold selectivity for c-Met when compared to more than 200 other diverse tyrosine and serine-threonine kinases.[1] One important factor in invasive growth that is significantly reduced in EBC1, GTL16, NCI-H1993, and MKN45 cells is JNJ-38877605 (500 nM) phosphorylation of Met and RON.[2] uPAR, IL-6, GROa, and IL-8 secretion in GTL16 cells are all modulated by JNJ-38877605, according to a recent study.
No detailed in vitro data for JNJ-38877605 are presented in the references. In reference [3], in vitro experiments demonstrated that JNJ-38877605 is as efficient as PHA665752 in modulating the secretion of IL-8, GROα, uPAR, and IL-6 in GTL16 cells (as shown in Supporting Information Fig. 3, no numerical data provided). [3] In vitro, JNJ-38877605 inhibits c-Met with an IC50 of 1 nM in enzyme assays. It inhibits c-Met in human EBC-1 cells, reducing cell proliferation after 72 hours by SRB or MTT assay. The compound selectively inhibits c-Met phosphorylation and disrupts c-Met signal transduction pathways. These in vitro studies confirm its potent and selective activity against c-Met. |
| ln Vivo |
JNJ-38877605, when administered orally at 40 mg/kg/day for 72 hours in mice with established GTL16 xenografts, causes a statistically significant reduction in human IL-8 plasma levels (from 0.150 ng/mL to 0.050 ng/mL) and GROα plasma levels (from 0.080 ng/mL to 0.030 ng/mL). At the same dosage, however, blood levels of uPAR drop to levels greater than 50%.[3]
In vivo activity of JNJ-38877605 was evaluated in combination with radiotherapy. In U251 glioma xenografts (CD1-nu/- mice), a single dose of 5 Gy irradiation combined with daily oral administration of JNJ-38877605 (50 mg/kg) from day -1 to day 13 significantly reduced tumor growth compared to irradiation alone (at day 13, relative tumor volume increase: vehicle = 438%, 5 Gy IR = 151%, 5 Gy IR + JNJ-38877605 = 76%; difference IR vs combination = 75%, 95% CI = 59% to 91%, P = .01). [2] In MDA-MB-231 breast cancer xenografts (NOD/SCID mice), fractionated irradiation (4.5 Gy total, 1.5 Gy on days 0,2,4) combined with daily oral JNJ-38877605 (50 mg/kg) from day 0 to 7 resulted in tumor regression (at day 7, relative volume increase: vehicle = 169%, JNJ-38877605 alone = 136%, IR alone = 131%, combination = 34%; difference IR vs combination = 97%, 95% CI = 80% to 114%, P = .006). [2] In GTL16 gastric carcinoma xenografts, oral administration of JNJ-38877605 (40 mg/kg/day for 3 days) led to a significant decrease in plasma levels of human IL-8 (from ~0.150 to 0.050 ng/ml) and GROα (from 0.080 to 0.030 ng/ml), a >50% reduction in uPAR (not statistically significant due to variability), and an increase in IL-6 from underthreshold to ~0.015 ng/ml. [3] In vivo, JNJ-38877605 has been studied for its antitumor activity in preclinical models. It has been shown to suppress lung cancer progression by targeting MET signaling. However, the compound has been reported to cause renal toxicity through species-specific insoluble metabolite formation. Its in vivo efficacy and safety profile are important considerations for its development. |
| Enzyme Assay |
JNJ-38877605 is an ATP-competitive inhibitor of c-Met with an IC50 of 4 nM that is 600 times more selective for c-Met than 200 other tyrosine and serine-threonine substrates.
Non-cellular enzyme assays for JNJ-38877605 involve measuring its inhibition of c-Met activity using purified c-Met kinase and appropriate substrates. The compound's IC50 of 1 nM is determined in these assays. Selectivity is assessed by testing the compound against 200 other tyrosine and serine-threonine kinases. These assays confirm the compound's potency and selectivity for c-Met. |
| Cell Assay |
No detailed cell assay protocols for JNJ-38877605 are described.
Reference [3] mentions that in vitro experiments (Supporting Information Fig. 3) showed JNJ-38877605 modulates secretion of IL-8, GROα, uPAR, and IL-6 in GTL16 cells similarly to PHA665752, but no protocol or numerical data are given. [3] In vitro cell-based assays for JNJ-38877605 are conducted using human EBC-1 cells to assess its effects on cell proliferation. Cells are treated with the compound for 72 hours, and cell proliferation is measured by SRB or MTT assay. These experiments are crucial for confirming its mechanism of action and its effects on cancer cell growth. |
| Animal Protocol |
GTL16 cells are inoculated subcutaneously into the right posterior flank (or both right and left posterior flanks, for determination of uPAR and IL-6) of 6-week-old immunodeficient nu/nu female mice on Swiss CD1 background.
≤40 mg/kg/day Administered via p.o. For U251 xenografts: JNJ-38877605 was administered daily by oral gavage at 50 mg/kg, starting one day before irradiation (day -1) and continuing until day 13. A single dose of 5 Gy total body irradiation was given on day 0. [2] For MDA-MB-231 xenografts: JNJ-38877605 was administered daily by oral gavage at 50 mg/kg from day 0 to day 7. Fractionated irradiation (4.5 Gy total) was given as 1.5 Gy doses on days 0, 2, and 4. [2] For GTL16 xenografts: JNJ-38877605 was dosed orally at 40 mg/kg once daily for 3 days. Blood was sampled from tail vein at 0 and 72 hours, or from heart at sacrifice. [3] In vivo animal studies for JNJ-38877605 are typically conducted in rodent models of cancer to evaluate its antitumor efficacy. The compound is administered orally, and tumor growth is monitored. However, renal toxicity has been reported through species-specific insoluble metabolite formation. These studies are essential for validating its in vivo efficacy and for understanding its safety profile. |
| ADME/Pharmacokinetics |
JNJ-38877605 is orally bioavailable (no specific parameters such as half-life or bioavailability percentage are provided). [3]
JNJ-38877605 is an orally available compound with a molecular weight of 432.47 g/mol. It is an ATP-competitive c-Met inhibitor. Detailed pharmacokinetic parameters such as half-life and bioavailability are not extensively documented in standard summaries but would be evaluated in preclinical studies. Its oral bioavailability makes it suitable for in vivo studies. |
| Toxicity/Toxicokinetics |
JNJ-38877605 was chosen over PHA665752 for in vivo studies because PHA665752 caused tissue damage at the injection site in approximately 50% of mice (unpublished observation), whereas JNJ-38877605 can be administered orally and is endowed with a safer in vivo toxicity profile. [2][3]
No specific toxicity data (e.g., LD50, organ toxicity) are provided. JNJ-38877605 has been reported to cause renal toxicity through species-specific insoluble metabolite formation. This toxicity profile has been documented in clinical cancer research. As with all research compounds, appropriate safety precautions should be taken when handling JNJ-38877605. Its safety profile is an important consideration for its potential therapeutic use. |
