Definitions
- the present invention belongs to the field of pharmaceutical technology, and specifically relates to a pyridopyrimidine derivative and a pharmaceutical composition comprising these compounds, as well as their use in preparing drugs for treating diseases related to the PD-1/PD-L1 signaling pathway.
- PD-1 Programmed cell death receptor-1
- CD279 is a cell surface receptor expressed on activated T cells, natural killer T cells, B cells and macrophages (Greenwald et, Annu. Rev. Immunol 2005, 23: 515-548; Okazaki and Honjo, Trends Immunol 2006, (4): 195-201). It is a type I transmembrane protein composed of 268 amino acids and belongs to the CD28 family. PD-1 is mainly composed of three parts in structure: the extracellular immunoglobulin variable domain, the hydrophobic transmembrane region and the intracellular domain (Parry et al, Mol Cell Biol 2005, 9543-9553).
- the intracellular domain includes two phosphorylation sites located in the immunoreceptor tyrosine inhibitory motif (ITIM) and the immunoreceptor tyrosine conversion motif (ITSM), suggesting that PD-1 negatively regulates T cell receptor-mediated signals.
- ITIM immunoreceptor tyrosine inhibitory motif
- ITMS immunoreceptor tyrosine conversion motif
- PD-1 prevents the activation of T cells, thereby reducing autoimmunity and promoting self-tolerance.
- PD-1 is also believed to play a key role in inhibiting antigen-specific T cell responses in diseases such as cancer and viral infections (Sharpe et al, Nat Immunol 2007, 8, 239-245; Postow et al, J. Clinical Oncol 2015, 33, 1-9).
- the PD-1/PD-L1 signaling pathway can prevent excessive inflammation and autoimmune diseases induced by excessive attacks of the immune system on tissues.
- abnormal circumstances such as in tumor tissues and chronic HBV-infected tissues, there is overexpression of PD-L1.
- Overexpression of PD-1/PD-L1 and activation of the signaling pathway inhibit the activation and proliferation of functional T cells, inhibit anti-tumor immune responses, and cause the immune system to lose its inhibitory effect on the development of tumors, thereby accelerating the development and deterioration of tumors.
- a variety of drugs have been approved for this pathway.
- PD-L1 monoclonal antibodies such as Atezolizumab
- Atezolizumab have been approved for indications in urothelial carcinoma and non-small cell lung cancer, and more clinical studies are underway in tumor-related indications.
- macromolecular drugs compared with small molecules, macromolecular drugs have obvious disadvantages in aspects such as tissue penetration, pharmacokinetic properties, cost and usage. Therefore, the development of small molecule oral drugs on the PD-1/PD-L1 signaling pathway is still an unmet clinical need and has broad market prospects.
- BMS is one of the earliest drug development companies to conduct research on PD-L1 small molecule inhibitors.
- patent documents such as WO2017066227 and WO2018044963 and related academic articles, it has disclosed a series of small molecule compounds that can truly block the binding of PD-1 and PD-L1.
- the small molecule inhibitors currently reported to have entered the clinical stage include Incyte Corp’s oral PD-L1 inhibitor (INCB-086550), which was approved to enter clinical phase I in December 2018 for the treatment of advanced solid tumors.
- Gilead’s GS-4224 started clinical trials in the United States on August 8, 2019.
- MAX-10181 is the third small molecule PD-L1 inhibitor to enter clinical trials in the world, and started clinical phase I trials in Australia on October 10, 2019.
- Hongri Pharmaceuticals a domestic company, applied for clinical trials in China for the IMMH-010 molecule introduced from the Chinese Academy of Medical Sciences, and the IND was approved in April 2020.
- PD-1/PD-L1 blockers can be used for the clinical treatment of various tumors.
- antibody drugs have their own characteristics, such as high production cost, poor stability, injection and easy immunogenicity.
- Small molecule drugs have the advantages of good tissue permeability, convenient storage and transportation, low production cost, no immunogenicity and can usually be taken orally. Therefore, the development of small molecule inhibitors of PD-1/PD-L1 has significant application value and social value.
- the present invention provides a pyridopyrimidine derivative that inhibits the interaction between PD-1 and PD-L1, which can be used as a novel oral small molecule immunomodulator.
- the compound of the present invention has good in vivo exposure and sustained exposure time, and is targeted to tumor tissues, can be enriched in tumor tissues and form a higher tumor tissue exposure concentration, which helps to better exert anti-tumor activity during treatment, thereby achieving a better Excellent therapeutic effect.
- the present invention relates to a compound, which is a compound represented by formula (I), or a stereoisomer, tautomer, nitrogen oxide, hydrate, solvate, metabolite, pharmaceutically acceptable salt or prodrug thereof of the compound represented by formula (I),
