Abstract: Tumor immunotherapy has made great progress in recent years. In the tumor microenvironment, the binding of PD-1 and its ligand PD-L1 can promote tumor immune escape and tumor survival. Clinical studies have indicated that antibodies blocking PD-1 and PD-L1 have reliable effects on many advanced malignant tumors. However, no small-molecule inhibitors have been approved so far, indicating that the development of marketable small-molecules PD-1/PD-L1 targeted therapy drugs is a challenging process. Small-molecule inhibitors can overcome the limitations of monoclonal antibodies, including poor oral bioavailability, high cost, poor tissue and tumor penetration and long half-life, which prompt researchers to turn their attention to the development of peptide molecules and small-molecule inhibitors modulating PD-1/PD-L1 to overcome some disadvantages of monoclonal antibodies or targeting PD-L1 protein degradation as potential alternatives or supplements. In this review, we will focus on the peptide-based and nonpeptidic molecules against PD-1/PD-L1 base on the structural classification. More importantly, we also focus on the latest research progress of small-molecules mediated PD-L1 degradation mechanism.
