Description

Amide derivatives and use thereof Technical Field
the present application relates to amide derivatives or pharmaceutically acceptable salts thereof or all stereoisomers, tautomers and deuterated forms thereof, pharmaceutical compositions comprising the same and use thereof in the preparation of NLRP3 inhibitors.
Background
The NOD-Like Receptors (NLRs) of the nucleotide binding oligomerization domain (nucleotide-binding oligomerization domain, NOD) are a cytoplasmic located class of pattern recognition Receptors (Pattern Recognition Receptors, PRRs) within cells of mammals that play a very important role in the innate immune response. NLRs are a group of cytoplasmic proteins with signal transduction function, which are widely involved in the inflammatory response of the body. The NLRs family includes NODs, NALPs (NLRPs), CIITA (NLRA) and IPAF (NLRC), where NLRPs and NLRC subfamilies are the major two types of NOD-like receptors (NLRs), and NLRPs can be divided into inflammatory small members of NLRP1, NLRP3, NLRP6, NLRP7 and NLRP 12. NLRP3 inflammatory corpuscles are a polyprotein complex consisting of NLRP3 protein itself, caspase-1 and apoptosis-related plaque-specific-like protein containing CARD (ASC) capable of recognizing a variety of pathogenic microorganisms and stress-related endogenous signaling molecules. Classical NLRP3 inflammatory small body activation is stimulated and activated by two signals together, wherein the first signal activates a TLR4 (Toll like receptor) signal path, promotes nuclear transcription factor kB to enter the nucleus, and induces the generation of precursors such as IL-1 beta, IL-18 and the like. The second signal promotes the formation of the NLRP3/ASC/pro-caspase-1 complex, i.e., when activated, polymerizes with Apoptosis-related spot-like proteins (ASC, apoptisis-Associated Specklike Protein containing a CARD) containing caspase activation and recruitment domains, which in turn interact with cysteine protease caspase-1 to form a complex called an inflammatory body, and the precursor form of caspase (pro-caspase-1) self-cleaves into the activated form, (Wen, H., miao, E.A.) and Ting, J.P.message of NOD-like receptor-associated inflammasome activation 39,432-441 (2013)), cleaves the precursor form of pro-inflammatory cytokines IL-1 beta and IL-18, causing them to be converted into the active forms IL-1 beta and IL-18 and release to the extracellular, recruiting inflammatory cell aggregation, inflammatory response. ASC spot-like proteins can also recruit and activate caspase-8 (caspase-8), cleaving precursor forms of IL-I beta and IL-18 to convert to mature forms and initiate apoptosis. Non-classical NLRP3 inflammatory body activation does not depend on TLR4 signaling pathway activation, it is that caspase-11 directly recognizes intracellular LPS, initiates NLRP3 inflammatory body activation, and promotes activation and release of Gasderm D to mediate cell death. (Lamkanfi, M. & Dixit, v.m. mechanisms and functions of inprimmas.cell 157,1013-1022 (2014)).
Abnormal activation of NLRP3 inflammatory bodies is closely related to the occurrence of genetic CAPS disease Mu Keer-wels syndrome (mWS), familial cold autoinflammatory syndrome, neonatal onset multisystem inflammatory disease, alzheimer's disease, parkinson's disease, nonalcoholic fatty liver, atherosclerosis, asthma, kidney disease, enteritis, tumor, gout, neurodegenerative disease, diabetes, and obesity.
Current drugs for the treatment of NLRP3 related diseases include the recombinant IL-1 receptor antagonist anakinra, the neutralizing IL-1 beta antibody canakinumab, and the soluble IL-1 receptor trap rilonacept, all of which are biologicals. In recent years, rebecca C col et al report that a novel sulfonylurea small molecule NLRP3 inhibitor compound MCC950 inhibits NLRP3 inflammatory body activity in nanomolar scale, and other small molecule compounds have been shown to inhibit NLRP3 inflammatory bodies, such as: glibenclamide, parthenolide, 3, 4-Methylenedioxy-beta-nitrostyrene (He, Y.et al 3, 4-methylendioxy-beta-nitrostyrene inhibits NLRP3 inflammasome activation by blocking assembly of the inflammasiome.J.biol. Chem.289,1142-1150 (2014)) and dimethyl sulfoxide (DMSO). However, the above drugs or small molecules have problems of low specificity or poor activity. Therefore, there is a need to develop a new generation of small molecule NLRP3 inhibitors with high specificity and high activity for the treatment of autoimmune diseases caused by NLRP3 mutations.
