BMS-1001 is a novel and potent small molecule inhibitor of the PD-1/PD-L1 protein protein interaction with IC50 value of 2.25 nM in cell free assays. By Bristol-Myers Squibb, it was first uncovered. Significant advancements in the treatment of cancer have been made possible by blocking the PD-1/PD-L1 immune checkpoint pathway with monoclonal antibodies. Numerous drawbacks of antibody-based immunotherapies include their immunogenicity, short half-lives, and high cost of the antibodies. Due to the lack of complete structural knowledge for this pathway, small-molecule PD-1/PD-L1 inhibitor development is slow and may not be able to address these issues. BMS-1001 and its analogs, the first chemically derived PD-1/PD-L1 inhibitors, were recently made public by Bristol-Myers Squibb.

Enzyme Assay |
BMS disclosed recently the first nonpeptidic small molecule inhibitors against the PD-1/PD-L1 pathway that showed the activity in a homogeneous time-resolved fluorescence (HTRF) binding assay; however no further data supporting their activity were provided.

Cell Assay |
BMS-1001 reduces the inhibition of T-cell receptor-mediated activation of T lymphocytes by soluble PD-L1. The cell surface-associated PD-L1 inhibitory effect is successfully reduced by BMS-1001. [1] The ECs are stimulated with the anti-CD3 antibody in the presence of the recombinant human sPD-L1 in order to assess the effect of the BMS on the inhibition of T cells by soluble PD-L1. For this, 5 g/ml of the anti-CD3 antibody or the isotype control solution in PBS are coated onto the 96-well white flat bottom plates overnight at 4°C. After the plates have been dried and three PBS washes, the antibody solution is removed. In the presence of BMS-1001 or a corresponding volume of DMSO, PBS is supplemented with penicillin/streptomycin solution (100 U/ml final concentration each) and diluted with sPD-L1 (aa 18–134). The solution is then poured into each well of the antibody-coated plate in a volume of 15 μl. Before adding 60 μl of the cell solution to each well, ECs are centrifuged and diluted to 50 000 per ml. In its final state, sPD-L1 had a concentration of 10 μg/ml (0.6 μM). The final BMS-1001 concentrations are 0.12, 0.3, 1.2, and 3 μM, corresponding to the molar ratios of 1:5, 1:2, 2:1, and 5:1 between BMS and sPD-L1. Utilizing the Bio-Glo Luciferase Assay System, the cells are cultured for 24 hours before the luciferase activity assay is carried out.

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80: Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 :Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).
