Description

[Technical Field]

[0001] The present invention relates to the field of medicinal chemistry, specifically to novel tricyclic heteroaryl group-containing derivatives, their synthesis methods and use as NLRP3 inhibitors in the manufacture of drugs for treating multiple related diseases, such as tumors. [Background technology]

[0002] NLRP3 (NOD-like receptor family, pyrin domain-containing protein 3) inflammatory bodies are multiprotein complexes containing the core member nucleotide-binding oligomerization domain-like receptor (NLRP3), the linker protein apoptosis-associated speck-like protein (ASC, apoptosis-associated speck-like protein containing a caspase activation and recruitment domain), and the aspartate-specific cysteine ​​protease (caspase-1) precursor, which are primarily involved in the inflammatory response process in the body. As an intracellular receptor protein, NLRP3 recognizes specific inflammatory signals. Upon stimulation, NLRP3 binds to the linker protein ASC to form the NLRP3-ASC complex. The multimerized NLRP3-ASC complex then forms a larger complex with the caspase-1 precursor, which is called the inflammatory body. The generation of inflammatory bodies leads to the activation of caspase-1, which further cleaves and processes the inflammatory factors IL-1β and IL-18 precursors to secrete active IL-1β and IL-18, promoting the development of inflammatory responses and leading to inflammatory cell death, i.e., pyroptosis. ASC can also recruit and activate caspase-8, which cleaves IL-1β and IL-18 precursors and induces apoptosis.

[0003] Caspase-1 cleaves IL-1β and IL-18 precursors to generate active IL-1β and IL-18, which are secreted extracellularly. Activated caspase-1 can also cleave GSDMD (gasdermin D) and induce cell pyroptosis. By regulating the pyroptotic cell death pathway, caspase-1 can also mediate the release of alarmins, such as IL-33 and HMGB1 (high mobility group box 1). Caspase-1 can also cleave the intracellular IL-1R2 receptor, leading to its degradation and the release of IL-1α. Other caspase-1 substrates, such as cytoskeletal proteins and proteins involved in the glycolytic signaling pathway, may also be involved in caspase-1-dependent inflammatory responses.

[0004] Cytokines activated by NLRP3 inflammatory bodies promote the development of inflammatory responses and, together with other cytokine signaling pathways, establish immune responses to infection and injury. For example, the IL-1β signaling pathway induces the release of the pro-inflammatory factors IL-6 and tumor necrosis factor (TNF). In the absence of T cell receptor (TCR) engagement, IL-1β and IL-18 cooperate with IL-23 to induce memory CD4+ Th17 cells and γδ T cells to produce IL-17. IL-18 and IL-12 also cooperate to induce memory T cells and natural killer cells to secrete IFN-γ, promoting Th1 immune responses.

[0005] Other intracellular pattern recognition receptors, such as the NLR (nod-like receptor) family members NLRP1 and NLRP4, as well as non-NLR family members such as the double-stranded DNA sensor AIM2 (absent in melanoma 2) and IFI16 (interferon gamma inducible protein 16), can also form inflammatory bodies. An indirect, atypical signaling pathway downstream of caspase-11 can also activate IL-1β, which is dependent on NLRP3.

[0006] Abnormal activation of NLRP3 leads to the development of many diseases, including comprehensive Muckle-Wells syndrome (MWS), familial cold autoinflammatory syndrome (FCAS), and neonatal-onset multisystem inflammatory disease (NEID). NLRP3 is also involved in mediating the development of many complex diseases, including multiple sclerosis, type 2 diabetes, obesity, Alzheimer's disease, gout, and atherosclerosis. Its role in diseases of the central nervous system, lungs, liver, and kidneys has also garnered significant attention. Therefore, the development of NLRP3 inhibitors holds great promise for broad clinical applications. Summary of the Invention [Problem to be solved by the invention]

[0052] Unless stated to the contrary, the terms used in the following specification and claims have the following meanings: "Aryl group" refers to an all-carbon monocyclic or fused polycyclic (i.e., rings that share adjacent pairs of carbon atoms) group having a conjugated π-electron system, such as a phenyl group or a naphthyl group. The ring of the aryl group may be fused to other cyclic groups (including saturated and unsaturated rings), but does not contain heteroatoms such as nitrogen, oxygen, or sulfur, and the point of attachment to the parent must be a carbon atom in the ring that has a conjugated π-electron system. Aryl groups may be substituted or unsubstituted. The following are some examples of aryl groups, and the present invention is not limited to these aryl groups: [ka]

[0053] A "heteroaryl group" refers to an aromatic monocyclic or polycyclic group containing one or more heteroatoms (optionally selected from nitrogen, oxygen, and sulfur), or a polycyclic group formed by condensing a heterocyclic group (optionally containing one or more heteroatoms selected from nitrogen, oxygen, and sulfur) with an aryl group, with the linking site being located on the aryl group. The heteroaryl group may be optionally substituted or unsubstituted. The following are some examples of heteroaryl groups, and the present invention is not limited to these heteroaryl groups. [ka]

[0054] A "heterocyclic group" refers to a saturated or partially saturated monocyclic or polycyclic hydrocarbon substituent in which one or more ring atoms are selected from nitrogen, oxygen, or sulfur, and the remaining ring atoms are carbon. Non-limiting examples of monocyclic heterocyclic groups include pyrrolidyl, piperidyl, piperazyl, morpholyl, thiomorpholyl, and homopiperazyl. Polycyclic heterocyclic groups include spirocyclic, fused-ring, and bridged-ring heterocyclic groups. A "spirocyclic heterocyclic group" refers to a polycyclic heterocyclic group in which each ring in the system shares an atom (called a spiro atom) with the other rings in the system, in which one or more ring atoms are selected from nitrogen, oxygen, or sulfur, and the remaining ring atoms are carbon. A "fused-ring heterocyclic group" refers to a polycyclic heterocyclic group in which each ring in the system shares an adjacent pair of atoms with another ring in the system, and one or more rings may contain one or more double bonds, but no ring has a completely conjugated π-electron system, and one or more ring atoms are selected from nitrogen, oxygen, or sulfur, with the remaining ring atoms being carbon.

When a heterocyclic group contains both saturated and aromatic rings (e.g., a saturated ring and an aromatic ring are fused together), the bond to the parent ring is always located on the saturated ring. Note: When the bond to the parent ring is located on the aromatic ring, the group is referred to as a heteroaryl group, not a heterocyclic group. The following are some examples of heterocyclic groups, and the present invention is not limited to these heterocyclic groups. [ka]

Unless otherwise specified, an optionally substituted group may have one substituent selected from a specified group at any substitutable position of the group, and the substituents may be the same or different at each position. A cyclic substituent, such as a heterocyclic group, may be linked to another ring, such as a cycloalkyl group, to form a spiro-bicyclic ring system, i.e., the two rings share one carbon atom. As will be appreciated by those skilled in the art, combinations of substituents envisioned by the present invention are those that are stable or chemically feasible. The substituents may be, for example, C 1-8 Alkyl group, C 2-8 Alkenyl group, C 2-8 Alkynyl group, C 3-8 Cycloalkyl groups, 3-12 membered heterocyclic groups, aryl groups, heteroaryl groups, halogens, hydroxy groups, carboxy groups (-COOH), C 1-8 Aldehyde group, C 2-10 Acyl group, C 2-10 Examples of the hydroxyl group include, but are not limited to, an ester group and an amino group.
