MK-8033 is a novel, potent, selective, ATP competitive small-molecule, dual inhibitor of c-Met/Ron (IC50=1 nM Wt c-Met) under investigation as a treatment for cancer. The goal of developing MK-8033 was to lessen the time-dependent inhibition of CYP3A4 (TDI) that individuals in this structural class exhibit. To obtain MK-8033 and its analogues, a unique two-step protocol for the synthesis of benzylic sulfonamides was created. Crucially, MK-8033 completely inhibits the growth of tumors in a c-Met amplified (GTL-16) subcutaneous tumor xenograft model. This is noteworthy because, unlike c-Met inhibitors that do not preferentially bind to the active kinase conformation, MK-8033 exhibits equal potency against a panel of oncogenic activating mutations of c-Met.

| ln Vitro |
MK-8033 (Compound 11r, 10 μM) showed a 31% CYP3A4 (cytochrome P450 3A4) inhibition[1].
MK-8033 (1 μM, 2 h) inhibits the c-Met-dependent gastric cancer cell line GTL-16's Y1349 phosphorylation (IC50: 0.03 μM)[1]. MK-8033 (1-10 μM, 72 h) suppresses the growth of GTL-16 cells (IC50: 0.58 μM)[1]. MK-8033 inhibits oncogenic c-Met activation loop mutants with IC50s ranging from 0.6 to 1 nM. It binds more tightly to phosphorylated c-Met (Kd: 3.2 nM) than to its unphosphorylated counterpart (Kd: 10.4 nM).[1] MK-8033 (0.1-10 μM, 2 h) decreases c-Met, ERK, and Akt phosphorylation in EBC-1 and H1993 cells[2]. MK-8033 (1 μM, 1 h) increases the radiation sensitivity of high c-Met-expressing H1993 and EBC-1 cells[2]. MK-8033 (10 μM, 6 h) reduces DNA repair and increases γ-H2Ax levels in comparison to double irradiation in A549 cells[2]. MK-8033 (2 μM, 72 h) causes G-alpha protein mutant UM (uveal melanoma) cells to proliferate less, but induces apoptosis somewhat[3]. |
| ln Vivo |
MK-8033 (Compound 11r, oral administration, 3-100 mg/kg, twice daily for 21 days) inhibits tumor growth in GTL-16 c-Met amplified gastric tumor xenografts[1].
MK-8033 shows good bioavailability (35% for rats, 33% for dogs) and moderate clearance (t1/2: 0.8 h for rats, 3.1 h for dogs)[1]. |

| Solubility (In Vitro) |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 1 mg/mL (2.12 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 10.0 mg/mL clear DMSO stock solution to 400 μL of PEG300 and mix evenly; then add 50 μL of Tween-80 to the above solution and mix evenly; then add 450 μL of normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 1 mg/mL (2.12 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 10.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. (Please use freshly prepared in vivo formulations for optimal results.) |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
