NVP-CGM097 (also called CGM-097; CGM097; NVP-CGM-097; NVP CGM097) is a novel, highly potent, orally bioavailable and selective MDM2 ( (human homolog of double minute 2) inhibitor with antitumor activity. With an IC50 of 1.7±0.1 nM, it blocks MDM2-p53. The Mdm2 protein's p53 binding site is where it binds, breaking up the interaction between the two proteins and activating the p53 pathway. CGM097, a p53/HDM2 interaction inhibitor, prevents the HDM2 protein from attaching to the p53 transcriptional activation domain when taken orally. By preventing this HDM2-p53 interaction, p53's enzymatic degradation by proteosomes is slowed down. This could lead to the restoration of p53 signaling and, consequently, the p53-mediated induction of tumor cell apoptosis.

NVP-CGM097 binding to MDM2 is species dependent. It was shown to be selective for the p53:MDM2 interaction compared to the p53:MDM4 interaction (1176-fold selectivity) and the Ras:Raf interaction (3000-fold selectivity). Additionally, NVP-CGM097 exhibited no discernible activity against Bcl-2:Bak, Bcl-2:Bad, Mcl-1:Bak, Mcl-1:NOXA, XIAP:BIR3, and c-IAP:BIR3 protein-protein interactions. With an IC50 of 0.224 μM, NVP-CGM097 showed its capacity to block the p53:MDM2 interaction in living cells by significantly redistributing wild-type p53 into the cell nucleus. Treatment with NVP-CGM097 results in nuclear translocation of p53, which inhibits cell growth in a way that is p53-dependent[1].

| ln Vivo |
After iv administration, the total blood clearance (CL) of NVP-CGM097 was 5 mL/min/kg for mouse, 7 mL/min/kg for rat, 3 mL/min/kg for dog, and 4 mL/min/kg for monkey. NVP-CGM097 demonstrated a consistent low total blood CL in all species (5–10% of hepatic blood flow) based on the corresponding hepatic blood flows. In rodents and monkeys, the apparent terminal half-life (t1/2) was long (6–12 h), but in dogs, it was significantly longer (20 h). The drug was effectively absorbed after oral administration, with Tmax lasting between 1 and 4.5 h in each of the tested species. In mice, rats, and dogs, the oral bioavailability (%F) was high; in monkeys, it was moderate.

| Cell Assay |
In 96-well plates, cells were seeded at the proper densities (Bon1 cells: 1500 cells/well, NCI-H727 cells: 2000 cells/well, and Got1 cells: 50000 cells/well) and grown for 24 hours in complete medium containing serum and antibiotic. The next day, the cells were incubated with various concentrations of NVP-CGM097 (0.1 nM-2500 nM), 5-fluorouracil (100 nM-100 µM), streptozotocin (1 nM-100 µM), temozolomide (1 µM-1 mM), everolimus (10 nM) or octreotide (100 nM-10 µM) in 10% FBS medium (antibiotic-free). The metabolic activity was assessed using the "Cell Titer 96 Aqueous One Solution" cell proliferation assay after 48 hours, 96 hours, 144 hours, or 216 hours. Using an ELISA plate reader, the measurement was carried out at 492 nm.

| Animal Protocol |
Rats: Female athymic rats bearing subcutaneous xenotransplants of SJSA-1 tumors (n=5-12) are treated at 5, 10, 20, or 30 mg/kg or three times a week on Monday, Wednesday, and Friday (3qw M, W, F) at 30 or 70 mg/kg po for 14 days. Plasma AUCs are determined at the end of the study. Positive numbers indicate the percentage of tumor growth inhibition (T/C); negative numbers indicate the percentage of tumor regression.

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (3.79 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 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL 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: 2.5 mg/mL (3.79 mM) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 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.
