Description

Spirochroman compounds

[0001] The present invention relates to a spirochroman compound useful as a pharmaceutical. More specifically, the present invention relates to a spirochroman compound or a pharmacologically acceptable salt thereof that has an IL-17 modulatory activity and is useful as a therapeutic agent for diseases associated with IL-17.

[0002] Psoriasis is a chronic inflammatory skin disease caused by a complex interaction of genetic, environmental, and immune factors. Psoriasis is classified into five disease types: plaque psoriasis, guttate psoriasis, erythrodermic psoriasis, pustular psoriasis, and psoriatic arthritis. Psoriasis is characterized by multiple, scaly, infiltrative erythema covering the entire body, significantly impairing patients' quality of life (QOL). Histologically, psoriasis manifests as epidermal cell proliferation and hyperkeratosis, along with inflammatory cell infiltration and vascular proliferation. Proinflammatory cytokines are thought to be deeply involved in the pathogenesis of psoriasis. Excessive cytokine production due to activated inflammatory and immune responses leads to reduced epidermal cell turnover, hyperproliferation, and abnormal keratinization. IL-17A, secreted by Th17 cells, is known to play a central role in the pathogenesis and exacerbation of psoriasis. IL-17A, a member of the IL-17 family of molecules, forms homodimers or heterodimers with other IL-17 family molecules and transmits signals through binding to the IL-17 receptor (IL-17RA / IL-17RC complex). IL-17A contributes to homeostasis by inducing the production of inflammatory mediators from various cells, including epithelial cells, and by promoting neutrophil migration, thereby contributing to infection defense, tissue repair, and inflammation induction. However, excessive activation of Th17 cells and increased IL-17A production can lead to immune abnormalities. Increased Th17 cell activity and increased IL-17A production have been observed in the blood and skin lesions of psoriasis patients. IL-17A, in cooperation with other inflammatory cytokines, activates epidermal cells and induces the secretion of antimicrobial peptides, inflammatory cytokines, and chemokines, which are thought to contribute to the chronic skin inflammation of psoriasis.

[0003] Given this relationship between IL-17A and psoriasis, many biologics that target IL-17 or the IL-17 receptor and inhibit IL-17 signaling have been developed and marketed for the treatment of moderate to severe psoriasis, demonstrating excellent clinical efficacy. However, no small molecule compounds with IL-17 modulatory activity have been marketed to date. Therefore, there is a need for orally available small molecule compounds (e.g., inhibitors) with IL-17 modulatory activity that are useful for the treatment of IL-17-mediated diseases.

[0004] Spirocyclic compounds having IL-17 modulatory activity are described in Patent Documents 1 to 5 and Non-Patent Document 1. However, the spirochroman compound of the present invention is not described in any of these documents.

When formulated separately, these preparations can be administered separately or simultaneously. In addition, the dosage of the compound represented by formula (I) or its pharmacologically acceptable salt may be appropriately reduced depending on the dosage of the other drug used in combination.

[0168] The compound represented by formula (I) may be appropriately converted into a prodrug for use. For example, a prodrug of the compound represented by formula (I) can be produced by introducing a prodrug-constituting group using a prodrug-converting reagent such as a corresponding halide, followed by purification. Examples of the prodrug-constituting group include those described in "Development of Pharmaceuticals" (Hirokawa Shoten, 1990), Vol. 7, pp. 163-198.
