The present invention provides Immunosuppressive compounds capable of inhibiting the programmed cell death 1 (PD1) signalling pathway. The present invention further provides peptide based compositions for treatment of cancer or treatment of infections via immunopotentiation caused by inhibition of immunosuppressive signalling induced by PD-1, PD-L1, or PD-L2 and therapies using them, immunopotentiative substrates included as the active ingredient. Further, the invention provides pharmaceutical compositions comprising the Immunosuppressive peptide compounds or modified peptide moieties for preventive and/or therapeutic agents for cancer, cancer metastasis, immunodeficiency, an infectious disease or the like and an application of PD-1 or PD-L1 as a testing or diagnostic agent or a research agent for such a disease.
本发明提供了能够抑制程序性细胞死亡1(PD1)信号通路的免疫抑制化合物。本发明还提供了基于肽的组合物,通过抑制由PD-1,PD-L1或PD-L2诱导的免疫抑制信号而引起免疫增强,用于治疗癌症或感染的治疗方法,包括作为活性成分的免疫增强底物。此外,本发明提供了包含免疫抑制肽化合物或修饰肽基团的药物组合物,用于预防和/或治疗癌症,癌症转移,免疫缺陷,传染病或类似疾病的预防性和/或治疗性剂,并将PD-1或PD-L1应用为测试或诊断剂或用于此类疾病的研究剂。
