Description
Technical Field
The invention belongs to the technical field of medicinal chemistry, and particularly relates to a biphenyl sulphathiadiazoles derivative, a preparation method thereof, and application of the biphenyl sulphathiadiazoles derivative as a PD1/PD-L1 inhibitor in antitumor drugs.
Background
Although we hope that the immune system will automatically treat cancer cells as "foreign", due to the unique and widely variable nature of tumor cells, a balance between the immune system and the tumor is often reached-tumor tolerance, and immune checkpoint dysregulation becomes one of the major causes of tumor tolerance. Immune checkpoints are a class of immunosuppressive molecules that can modulate the intensity and strength of immunity. The signaling pathway regulated by programmed cell death protein 1(PD-1) and its cognate ligand Programmed Death Ligand (PDLS) is of great interest in the development of anti-cancer drugs. Over-expression of the PD1 ligand in tumor cells suppresses the body's immune system, preventing the immune system from killing tumor cells. One of the basic ideas of tumor antibody therapy is to block PD1/PD-L1 protein-protein interaction (PPI), thereby activating the anti-tumor immune response of T cells and eliminating tumor cells. One of the basic ideas of tumor antibody therapy is to block PD1-PDL protein-protein interaction (PPI), thereby activating T cell anti-tumor immune response and eliminating tumor cells. One of the basic ideas of tumor antibody therapy is to block PD1/PD-L1 protein-protein interaction (PPI), thereby activating the anti-tumor immune response of T cells and eliminating tumor cells. Research shows that the application of monoclonal antibodies to the treatment of the advanced melanoma, the cell lung cancer (NSCLC) and the Renal Cell Carcinoma (RCC) causes lasting objective reaction, and compared with the traditional treatment, the survival time of the patient is obviously prolonged.
In conclusion, the research on novel PD1/PD-L1 inhibitor with stronger specificity is important for the clinical immunotherapy of tumor drug patients.

First, HTRF homogeneous time-resolved fluorescence technique.
The test principle is as follows: the HTRF PD-1/PD-L1 binding assay kit developed by Cisbio, Inc., the PD-1/PD-L1 binding assay was intended to measure the interaction between PD-1 and PD-L1 proteins. The interaction between Tag1-PD-L1 and Tag2-PD-1 was examined by using anti-Tag1-Europium (HTRF donor) and anti-Tag2-XL665 (HTRF acceptor). When the donor and acceptor antibodies are brought into proximity due to the close binding of PD-L1 and PD-1, excitation of the donor antibody induces a fluorescence resonance energy transfer ((FRET) towards the acceptor antibody, which in turn emits specifically at 665 nm. this specific signal is proportional to the extent of the PD-1/PD-L1 interaction.
The test method comprises the following steps: the compounds of the invention were tested for their inhibitory effect on PD-1/PD-L1, in accordance with the instructions. Dosing, control and negative control groups were preplaced in 384-well plates, with triplicate wells per group. Sequentially adding 4 mu L of LTag1-PD-L1 working solution and 4 mu L of Tag1-PD-1 working solution into each hole, and uniformly blowing and beating; then 2. mu.L of compound diluent is added into each well, mixed evenly and incubated for 15min at room temperature, Anti-Tag1-Europium and Anti-Tag2-XL665 are added into each well in sequence, the membrane is sealed and incubated for 2 h in dark, a Tecan microplate reader is used to read fluorescence values (Ex:320 nM; Em:620 and 665nM), and then the inhibition rate and the fitting IC are calculated50See table 1.
The compounds of Table 1 were tested for their inhibitory activity against PD-1/PD-L1 (IC 50).
