The invention belongs to the field of medicinal chemistry and pharmacology, and relates to application of a novel glycolipid TLR2 agonist 13-C in preparation of vaccine adjuvants and anti-tumor treatment. The compound is excellent in human TLR2 agonist activity, EC50 reaches 2.2 nM, and the compound is simple in structure, easy to prepare and excellent in solubility and has industrial application potential. In a B16-OVA tumor model, the antibody induction capacity of the compound is superior to that of a positive control drug Diprovocim, and the anti-tumor activity of the compound is more remarkable; in addition, PD-L1 expression of tumor tissue can be effectively down-regulated, and a synergistic anti-tumor effect is generated with a PD-L1 monoclonal antibody Atezolizumab. Besides, 13-C and a vaccine adjuvant QS-21 are combined for use, so that a synergistic enhancement effect is achieved, the antibody titer induced by a vaccine can be remarkably improved, antibody subtypes are enriched, meanwhile, cellular immunity and humoral immunity response of an organism are stimulated, and the effect of dual immune activation is achieved.

Liquid pharmaceutical formulations comprising anti-PD-L1 antibodies for subcutaneous administration are provided.SOLUTION: Provided is a liquid pharmaceutical formulation comprising atezolizumab in a concentration of 100g / L to 150g / L, histidine-acetate in a concentration of 15mM to 25mM, sucrose in a concentration of 200mM to 280mM, polysorbate in a concentration of 0.04% (w / v) to 0.08% (w / v), methionine in a concentration of 5mM to 15mM, hyaluronidase in a concentration of 1000U / ml to / ml, and a pH of 5.6 to 6.0, wherein the liquid pharmaceutical formulation is for subcutaneous administration. 3000U.SELECTED DRAWING: Figure 9B

The present application relates to pyrazole derivatives as inhibitors of the PD-1 / PD-L1 interaction. The applicants have designed compounds of general formula (I) wherein R ', R2, y3, R3, R4, R5, R6 and R7 are as defined herein, which are effective in blocking PD-1 / PD-L1 interactions to restore an anti-tumor immune response in a subject and eradicate any tumors in which dormant tumor cells and PD-L1 participate in immune escape. The inventor verifies that these compounds block the PD-1 / PD-L1 interaction by performing physical and chemical tests (MST, NanoDSF) and in vitro biological tests (FRET assay, Pralomig block assay, T cell assay). These compounds have affinity (Kd) in the order of pM, which Kd is higher than the Kd of the antibody Atezumab used in clinical use, and have IC50 comparable to or higher than that observed using Atezumab. Therefore, the invention also relates to a pharmaceutical composition containing the compound and application of the pharmaceutical composition in treatment of PD-1-PD-L1 interaction related diseases (cancers, chronic inflammatory diseases, neurological diseases and chronic infections).

The present application belongs to the technical field of biological medicine and immunology, and particularly relates to a single-domain antibody targeting human and cynomolgus monkey PD-L1 cross-binding and application thereof. The single-domain antibody has specificity against human and cynomolgus monkey PD-L1, and shows strong binding efficiency in the binding detection with a PD-L1 target protein or a PD-L1 overexpression cell. In the detection of blocking PD-1 / PD-L1 function, part of the single-domain antibodies even show a blocking effect significantly better than Atezolizumab, which confirms that the single-domain antibody prepared by the present application can be used for the diagnosis, treatment and prognosis detection of PD-L1 positive tumors. Meanwhile, the single-domain antibody has cross-binding ability across species, and can be directly used for preclinical pharmacodynamics and safety evaluation, without the need to develop species-specific alternative antibodies, so as to achieve "one target with double effect".
