N-deacetylated BMS-202, the deacetylated product of BMS-202 (also known as PD1-PDL1 inhibitor 2, BMS 202, BMS202), is a inhibitor of the PD-1 (Programmed death- 1)/PD-Ll (Programmed death-ligand 1) protein/protein interaction with potential anticancer activities. BMS-202 inhibits the interaction between PD-1/PD-Ll and may improve the therapeutic immune response to a variety of tumors with different histologies. Antibodies against PD-Ll have been shown to restore and enhance T cell activation in numerous systems by blocking the PD-1/PD-Ll ligation. The compound BMS-202, which binds to and causes the dimerization of PD-L1, serves as an example of the structural basis for small molecules' ability to block the PD-1/PD-L1 interaction.

| Enzyme Assay |
In an HTRF assay buffer, which consists of dPBS supplemented with 0.1% (with v) bovine serum albumin and 0.05% (v/v) Tween-20, all binding studies are carried out. In the PD-l-Ig/PD-Ll-His binding assay, the inhibitors are first pre-incubated with PD-Ll-His (10 nM final) for 15 m in 4 μL of assay buffer, and then PD-l-Ig (20 nM final) is added in 1 L of assay buffer and further incubated for 15 m. It is possible to use PD-L1 from mice, cyno, or humans. Allophycocyanin (APC) labeled anti-His (20 nM final) and anti-Ig (1 nM final) labeled with europium crypate are used to detect HTRF. HTRF detection buffer is used to dilute the antibodies, and 5 μL is dispensed on top of the binding reaction. After 30 minutes of equilibration, the reaction mixture is given another chance to settle, and an En Vision fluorometer is used to measure the signal (665 nm/620 nm ratio). Additional binding assays have been established between CD80-His/PD-Ll-Ig (100, 10 nM, respectively), CD80-His/CTLA4-Ig (10, 5 nM, respectively), and PD-1-Ig/PD-L2-His (20, 5 nM, respectively).

| Cell Assay |
Particularly in a tumor microenvironment, the programmed death-1/programmed death-ligand 1 (PD-1/PD-L1) interaction dominates the suppression of T cell responses, preventing tumor cells from being lysed. With an IC50 value of 18 nM, PD-1/PD-L1 inhibitor 2 is said to prevent PD-L1 and PD-1 interaction.

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (6.62 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 (6.62 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 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. View More

*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.
