Definitions

  • the present invention requires an invention patent application submitted in China on March 31, 2022, titled “A class of bifunctional chimeric heterocyclic compounds of interleukin-1 receptor-related kinases and their preparation methods and uses” and the application number is 202210334860.3 And priority is given to the invention patent application submitted in China on September 28, 2022, titled “A class of bifunctional chimeric heterocyclic compounds of interleukin-1 receptor-related kinases and their preparation methods and uses” with application number 202211214397.5 The entire contents of the above patent application are incorporated herein by reference.
  • the invention belongs to the field of medical technology. Specifically, the invention relates to a bifunctional chimeric heterocyclic compound of interleukin-1 receptor-associated kinase 4 (IRAK4) and its preparation method, pharmaceutical composition and use.
  • IRAK4 interleukin-1 receptor-associated kinase 4
  • Interleukin-1 receptor-associated kinase 4 belongs to the IRAK family (including IRAK1, IRAK2, IRAK3 and IRAK4). It is encoded by the IRAK4 gene and is located on chromosome 12. As a threonine/serine protein kinase, IRAK4 consists of 460 amino acids, contains a kinase domain and a death domain, and has high homology with IRAK1, IRAK2, IRAK3 (IRAKM) and Pelle kinase. IRAK4 is the most unique member of the family in that it lacks a C-terminal domain and functions upstream of other members. IRAK4 is expressed in multiple tissues of the human body, but is mainly distributed in liver and lung tissues.
  • IRAK4 is a key regulator downstream of the interleukin-1 receptor (IL-1R) and toll-like receptors (TLRs) signaling pathways. It causes the transcription and expression of pro-inflammatory cytokine genes through the IL-1R/TLRs signaling pathway, triggering the innate immune response. Abnormal IL-1R/TLRs conduction is involved in a variety of autoimmune diseases, so IRAK4 has become a target of autoimmune diseases. An effective target; and MyD88 serves as a key regulator of the IL-1R/TLRs signaling pathway, making IRAK4 play an important role in tumors with MyD88 mutations.
  • IL-1R interleukin-1 receptor
  • TLRs toll-like receptors
  • IL-1R/TLRs receptors In the innate immune response, both IL-1R/TLRs receptors rely on MyD88 as a regulator to activate downstream inflammatory signaling pathways.
  • MyD88 factor When IL-1R/TLRs and ligands recruit MyD88 factor, MyD88 factor forms a dimer and further recruits IRAK4 through its N-terminal death domain.
  • IRAK4 exerts kinase activity through autophosphorylation and activates the substrate IRAK1, and IRAK1 then It undergoes a conformational change and forms a complex with TNF receptor-associated factor 6 (TRAF6).
  • TNF receptor-associated factor 6 TNF receptor-associated factor 6
  • TRAF6 activates NF- ⁇ B through the adapter protein TAK1, etc., causing the activated NF- ⁇ B to enter the nucleus and cause the transcription and expression of pro-inflammatory cytokine genes.
  • TRAF6 can also activate p38 and JNK, thereby activating the AP1 pathway.
  • IRAK4 overexpression can enhance the activity of LPS-induced NADPH oxidase, thereby affecting downstream MAPK signaling. Therefore, IRAK4 can trigger inflammatory responses through multiple pathways such as IRAK1/TRAF6/NF- ⁇ B/AP1 and NADPH/MAPK/AP1.
  • IRAK4 as a degradation target can provide new treatment options for the treatment of autoimmune diseases, inflammation and tumor-related diseases.
  • IRAK4 protein degradation targeting chimeras
  • TPD target protein degradation
  • thalidomide derivatives, lenalidomide and pomalidomide can recruit protein substrates to a ubiquitin ligase complex called cereblon (CRBN) to degrade the protein substrates.
  • CRBN cereblon
  • KT-474 SAR444656
  • KT-413 PROTAC bifunctional small molecules developed by Kymera Therapeutics are in clinical phase I as oral and intravenous IRAK4 degraders respectively.
  • Some of the company's other PROTAC bifunctional small molecules see WO2020264499A1, WO2020113233A1 and WO2022027058A1 also showed good PK and PD in animal experiments.
  • IRAK4 inhibitor PF-06650833 (see WO2015150995A1) developed by Pfizer has a therapeutic effect on autoimmune diseases such as rheumatoid arthritis and lupus erythematosus, and is currently in clinical phase II.
  • the object of the present invention is to provide a bifunctional chimeric heterocyclic compound that acts as a degradation product of IRAK4 through the ubiquitin proteasome pathway, as well as its pharmaceutical composition, preparation method and use.
