The compound is a compound shown in a formula (I), or an optical isomer or a pharmaceutically acceptable salt thereof. The invention also relates to the use of said compounds for the treatment or prevention of related diseases and disorders mediated by RIPK1 and to methods of using the same for the treatment of said diseases.

Description

Heterocyclic compounds as RIPK1 inhibitors
Technical Field
The present invention relates to heterocyclic compounds, pharmaceutical compositions containing them and their use as inhibitors of receptor-interacting protein kinase-1 (RIPKl). More particularly, the present invention provides novel heterocyclic compounds which are inhibitors of RIPK1, pharmaceutical compositions containing such compounds and methods of using the compounds in the treatment or prevention of related diseases and disorders mediated by RIPK 1. The invention also relates to a method for preparing said compounds.
Background
Receptor-interacting protein kinase 1 (Receptor-interacting protein kinase 1, RIPK 1) is a serine/threonine protein kinase involved in natural immune signaling. RIPK1 is a 76kDa protein with an N-terminal kinase domain, a C-terminal death domain and an intermediate domain with RHIM (receptor interacting protein homotypic interacting motif). Wherein the C-terminal death domain mediates homodimerization and heterodimerization with other death domain-containing proteins and the N-terminal kinase domain mediates trans-autophosphorylation to promote autoactivation.
RIPK1 has double immunoregulation function, and can be used as a bracket to promote MAPK and NF- κB signal channels to activate, thereby promoting inflammatory reaction and cell survival and inhibiting apoptosis; on the other hand, abnormally regulated RIPK1 activity will cause cell necrosis. RIPK1 is the primary regulator of cellular determinants of NF- κb signaling and death response in response to a wide range of inflammatory and pro-mortal stimuli in human disease (degerev, a., et. al PNAS, 2019, 116 (20), 9714-9722).
RIPK1 is widely expressed in various cell types, most abundantly in adipose, endothelial, perivascular cell clusters, and also in immune cell clusters (dendritic cells, macrophages and T cells). It was found that activation of RIPK1 kinase is present in pathological samples of neurodegenerative diseases such as autoimmune diseases, amyotrophic Lateral Sclerosis (ALS) and Alzheimer's Disease (AD). Anti-tumor necrosis factor-alpha (TNF-alpha) drugs have achieved significant clinical success in the treatment of human peri-inflammatory diseases such as rheumatoid arthritis, colitis, psoriasis, and the like. However, since tumor necrosis factor receptor 2 (TNFR 2) mediates nerve regeneration, treatment of central nervous system diseases is an unsafe factor. RIPK1 inhibitors safely ameliorate adverse TNF responses in the central nervous system without affecting TNFR 2. Thus, RIPK1 inhibitors may be a drug replacing TNF antibodies to compensate for the deficiencies of TNF antibodies.
Studies have shown that the RIPK1 small molecule inhibitor Necrostatin-1 (Nec-1), known in the art, can effectively block cell programmed necrosis (Degterev)et al. Nat. Chem. Biol.2005:112-119.), shows potent therapeutic effects in a variety of inflammatory diseases. GSK2982772 is being developed for use in peripheral autoimmune diseases such as psoriasis, rheumatoid Arthritis (RA) and ulcerative colitis. The brain penetration RIPK1 inhibitor DNL-788 is used for amyotrophic lateral sclerosis and the like. These experiments lay the foundation for advancing the clinical application of RIPK1 inhibitors.
RIPKl inhibitors are of great importance to the art, especially in inhibiting inflammatory diseases (e.g. Crohn's disease, ulcerative colitis etc.), sepsis and acute ischemic injury (e.g. sepsis, severe Covid-19, cerebral acute ischemic injury etc.), tumours, autoimmune system diseases (e.g. psoriasis, rheumatoid arthritis, systemic lupus erythematosus etc.) and neurodegenerative diseases (e.g. multiple sclerosis, huntington's disease, du's muscular dystrophy, frontotemporal dementia, alzheimer's disease, parkinson's disease etc.) and the like (Lauren M.etc. al.Nature Reviews Drug Discovery, 19(2020), 553–571）。
Thus, there remains a need to develop small molecule RIPK1 inhibitors with excellent activity.
