BMS-777607 (also called as BMS817378; ASLAN002) is an orally bioavailable inhibitor of the tyrosine kinase c-Met with potential antitumor activity. It exhibits 40-fold higher selectivity for inhibiting Met over Lck, VEGFR-2, and TrkA/B. In cell-free assays, it inhibits c-Met, Axl, Ron, and Tyro3 with IC50s of 3.9 nM, 1.1 nM, 1.8 nM, and 4.3 nM.
| Targets |
c-Met (IC50 = 3.9 nM); Axl (IC50 = 1.1 nM); Ron (IC50 = 1.8 nM); Tyro3 (IC50 = 4.3 nM)

| ln Vitro |
BMS-777607 is an ATP-competitive, selective Met kinase inhibitor that exhibits selective inhibition of proliferation in Met-driven tumor cell lines, including GTL-16 cell line, H1993, and U87. It also potently blocks the autophosphorylation of c-Met with an IC50 of 20 nM in GTL-16 cell lysates.[1] In PC-3 and DU145 prostate cancer cells, BMS-777607 inhibits c-Met autophosphorylation triggered by hepatocyte growth factor (HGF) with an IC50 of less than 1 nM. While BMS 777607 shows little effect on tumor cell growth, it does show almost complete inhibition at 0.5 μM on HGF-induced cell scattering in PC-3 and DU145 cells. In both cell lines, BMS 777607 also inhibits stimulated cell migration and invasion in a dose-dependent manner (IC50 < 0.1 μM).[2] BMS 777607 (~10 μM) applied for two hours to highly metastatic murine KHT cells potently eliminates basal levels of autophosphorylated c-Met with an IC50 of 10 nM without affecting the total amount of c-Met. This results in a dose-dependent inhibition of downstream signaling molecules such as Akt, p70S6K, S6, ERK, and others through phosphorylation. Applied at doses in the nanomolar range, which includes MET gene knockdown, BMS-777607 (~1 μM) treatment for 24 hours significantly suppresses KHT cell motility, invasion, and scatter while having a minimal impact on colony formation and cell proliferation.[3]

| ln Vivo |
BMS 777607 (6.25–50 mg/kg) given orally to athymic mice dramatically reduces the tumor volumes of GTL-16 human tumor xenografts without causing any apparent toxicity.[1] When injected with rodent fibrosarcoma KHT cells into 6-to 8-week-old female C3H/HeJ mice, BMS 777607 (25 mg/kg/day) significantly reduces the number of KHT lung tumor nodules (28.3%), improves the morphological hemorrhage, and significantly reduces the metastatic phenotype without apparent systemic toxicity when compared to the control treatment. In comparison to the vehicle control, a low dose of BMS 777607 (10 mg/kg) also provides a slight but insignificant inhibition of lung nodule formation.[3]

| Enzyme Assay |
The kinase reaction comprises 30 μL of kinase buffer (20 mM Tris-Cl, 5 mM MnCl2, 0.1 mg/mL BSA, 0.5 mM DTT), 3 μg of poly(Glu/Tyr), 0.12 μCi 33P γ-ATP, and 1 μM ATP expressed by the baculovirus. Cold trichloroacetic acid (TCA), added to a final concentration of 8%, ends the reaction after an hour of incubation at 30 °C. A Filtermate universal harvester is used to gather TCA precipitates onto GF/C unifilter plates, and a TopCount 96-well liquid scintillation counter is used to quantify the filters. To find the concentration needed to prevent 50% of substrate phosphorylation, dose response curves are created (IC50). In duplicate, BMS 777607 is dissolved at a concentration of 10 mM in dimethylsulfoxide (DMSO) and assessed at ten concentrations.

| Cell Assay |
The MTT assay and trypan blue exclusion are used to determine the proliferation and death of KHT cells after they are subjected to serial dilution of BMS 777607 for 96 hours. The BMS 777607 is added to KHT cell colonies, and after a 24-hour incubation period, the colonies are stained with crystal violet (0.1%) and captured on camera to measure the scattering of the cells. A sterile 1-milliliter pipette tip is used to make a 2-millimeter incision on the confluent KHT cell monolayer. The cell monolayer is then treated with BMS-777607 for a full day. To assess cell migration, the number of cells that have moved into the denuded area is counted on four adjacent fields at random. Commercial transwell inserts (8 μm pore membrane) pre-loaded with Matrigel are incubated with serum-free medium at 37 °C for two hours to allow Matrigel to rehydrate, whether or not BMS 777607 is present. This allows for the examination of cell invasion. Subsequently, cells suspended in serum-free medium are inserted into the upper chamber (5 × 103/insert), while the lower chamber is utilized as a chemoattractant for complete medium containing 10% FBS. The Matrigel is taken off and the inserts are stained with crystal violet after a 24-hour incubation period. The invaded cells on the filter's underside are counted and photographed.

| Animal Protocol |
Male Balb/C mice are used to study the pharmacokinetics of BMS 777607. After an overnight fast, two groups of animals (N = 6 per group; 20–25 g) receive BMS 777607 either by gavage (10 mg/kg) or as an intravenous (IV) bolus dose (5 mg/kg) through the tail vein. Six hours after the dose, the mice are fed. Retro-orbital bleeding is used to collect blood samples (about 0.2 mL) at 0.05 (or 0.25 for oral), 0.5, 1, 3, 6, 8, and 24 hours after the dose. A composite pharmacokinetic profile is produced by blenching half of the animals in each group at 0.05 (or 0.25 for oral), 1, 6, and 24 hours, and the other half at 0.5, 3, and 8 hours (3 mice per time point). Serum is obtained by allowing blood samples to coagulate and centrifuging them at 4°C (1500–2000 ×g). Before being analyzed by LC/MS/MS, serum samples are kept at about 20°C.
