Description

[0001] This application claims priority to PCT / CN2024 / 141170 filed December 20, 2024 and CN2025103733553 filed March 26, 2025, the entire contents of which are incorporated herein. TECHNICAL FIELD

[0002] The present application relates to macrocyclic compounds, pharmaceutical compositions thereof, and uses thereof. PRIOR ART

[0003] Tumor necrosis factor alpha (TNFa) is a homotrimeric protein composed of 157 amino acids. TNFa is initially expressed as a trimeric type II transmembrane protein, which can be cleaved by the metalloprotease TNF-converting enzyme to form soluble extracellular TNF. Both the transmembrane and soluble forms of TNFa can form biologically active trimeric complexes and transmit signals through TNF receptor 1 and TNF receptor 2. Binding of TNF to TNFR1 or TNFR2 can ultimately activate the transcription factor nuclear factor-kappa B (NF-kB), but there are significant differences in the signaling cascades mediated by each receptor to activate NF-kB. These complexities are compounded by multiple regulatory mechanisms of TNF expression itself, which allow cells to produce finely tuned, cell type-specific responses to TNF. Inappropriate or excessive activation of TNFa signaling is associated with chronic inflammation and ultimately leads to the development of pathological complications such as autoimmune diseases. (Brenner D., et al., Nat. Rev. Immunol., 2015, 15, 362-374; Kalliolias, G.D., et al., Nat. Rev. Rheumatol., 2016, 12, 49-62.).

[0004] As TNFa is an important regulator of inflammatory responses, a variety of TNFa modulators have been developed, including adalimumab, golimumab, certolizumab pegol, infliximab, and etanercept. Infliximab is a chimeric antibody whose Fab region contains a mouse amino acid sequence. Adalimumab and golimumab contain a human amino acid sequence. Certolizumab pegol is a humanized Fab fragment chemically coupled to polyethylene glycol. Etanercept is a fusion protein composed of the extracellular domain of a TNF receptor combined with the Fc fragment of human IgG1. (Jang, D.I., et al., Int. J. Mol. Sci., 2021, 22, 1-16; Willrich, M.A., et al., Transl. Res., 2015, 165, 270-282).

[0005] The disclosed compounds are modulators of human TNFα activity, which are beneficial for treating and / or preventing a variety of human diseases. Among them are inflammatory and autoimmune diseases, neurological and neurodegenerative diseases, pain and nociceptive sensory disorders, cardiovascular diseases, metabolic diseases, ocular diseases, and neoplastic diseases. As small molecules, they can have advantages over biologies. There is still a need for small molecule compounds with good biological activity. SUMMARY

[0006] The present invention relates to macrocyclic compounds, pharmaceutical compositions thereof, and uses thereof. The compounds of the present disclosure are useful as TNFα inhibitors and can be used in the treatment of inflammatory and autoimmune diseases.

[0007] The present disclosure provides a compound represented by Formula (I), a solvate thereof, a pharmaceutically acceptable salt thereof, or a solvate of a pharmaceutically acceptable salt thereof;
