Abstract
There is provided a nitrogen-containing heterocyclic compound represented by formula (I), or a stereoisomer, solvate, pharmaceutically acceptable salt, co-crystal or pharmaceutical composition thereof, and use thereof in preparing a medicament for treating/preventing IL-17A mediated diseases, wherein each group is as defined in the specification.
Description
The present invention relates to an IL-17A inhibitor and its use in the preparation of a medicament for the treatment of psoriasis, arthritis and multiple sclerosis.
Immune function is critical for maintaining homeostasis and for effective response to disease, and aberrant immune responses are well-established contributors to the pathophysiology of autoimmune disease. In certain disease states, some key pathways leading to these aberrant autoimmune responses have been found to be effective methods of therapeutic intervention. A recent example is the development of Interleukin (IL) -17 inhibitors. IL-17A is a well-recognized pro-inflammatory cytokine that plays a key role in chronic inflammation and is a major driver of tissue damage. IL-17A induces normal immune and inflammatory responses to pathogens, but can also contribute to chronic autoimmune diseases including psoriasis, spondyloarthritis, rheumatoid arthritis, and multiple sclerosis.
The IL-17 family consists of six cytokines (IL-17A through IL-17F). IL-17 receptor (IL-17R) refers to heterodimers formed by IL-17RA and IL-17RC subunits. IL-17A is a major pathological cytokine secreted by Th17 cells, which can signal through IL-17R as either homodimers or heterodimers (Isono, F. Et al Inhibiting RORgt/Th17axis for autoimmune disorders, drug Discovery Today (2014) 19 (8) volumes 1205-1211). In the skin and joints, IL-17A acts on cellular targets, including keratinocytes, endothelial cells, fibroblasts, osteoclasts, chondrocytes, and osteoblasts to stimulate the production of various antimicrobial peptides, chemokines, and pro-inflammatory and proliferative cytokines, which in turn promote tissue inflammation and bone remodeling. The critical importance of the IL-23/IL-17A axis for psoriasis pathogenesis has led to a number of novel biotherapeutic approaches targeting these cytokines. These biological agents significantly improve skin and joint symptoms in patients with moderate to severe psoriasis and psoriatic arthritis.
There is currently no effective oral administration treatment for moderate to severe psoriasis. Small molecule IL-17A inhibitors may provide efficacy comparable to anti-IL-17A antibodies for psoriasis and/or other IL-17A dependent diseases, such as psoriatic arthritis. While inhibiting IL-17A may increase susceptibility to opportunistic infections in certain circumstances, orally available small molecule inhibitors with relatively short half-lives may provide improved agents for controlling such risks. Oral agents may enable a patient to stop taking the drug and quickly clear the inhibitor from the body, thereby enabling a faster recovery of the ability to respond to the infection. Furthermore, anti-drug antibodies against anti-IL-17A antibodies may be present in some patients and may decrease the efficacy of antibodies against IL-17A over time. This inactivation pathway does not work with small molecule IL-17A inhibitors.
Thus, there remains a need for small molecule inhibitors of IL-17A to provide improved and/or orally available treatments for IL-17 mediated diseases. The compounds of the present invention are potent modulators of human IL-17 activity and are therefore useful in the treatment and/or prevention of a variety of human diseases, including inflammatory and autoimmune disorders, and in the treatment of psoriasis, rheumatoid arthritis, multiple sclerosis, and the like.
