Abstract
Description
Technical Field
[0001] This invention relates to the field of small molecule compounds, specifically to a small molecule compound that can be used to treat, prevent and alleviate autoimmune diseases such as rheumatoid arthritis, ulcerative colitis, or related inflammatory skin diseases such as psoriasis, eczema, vitiligo, etc. Background Technology
[0002] Protein kinases catalyze the phosphorylation of amino acids at specific sites in proteins. Based on amino acid phosphorylation, they can be classified into tyrosine kinases, serine kinases, and arginine kinases. JAK is a family of intracellular non-receptor tyrosine kinases, including four members: JAK1, JAK2, JAK3, and Tyk2. JAKs are mainly expressed in hematopoietic cells, leukocytes, and intestinal epithelial cells, and are responsible for mediating the signal transduction of various cytokines involved in inflammatory responses. When cytokines bind to cell surface receptors, JAKs are activated through autophosphorylation. Activated JAKs then activate the intracellular portion of the receptor by phosphorylation and recruit members of the STAT protein family. Subsequently, STATs are activated by JAK phosphorylation to form dimers, which detach from the receptor and enter the cell nucleus to regulate gene transcription, thereby affecting the cell's biological functions. The JAK (Janus Kinase)-STAT (Signal Transducer and Activator of Transcription Proteins) signaling pathway is the main pathway for the intracellular transmission of signals triggered by the binding of inflammatory cytokines and receptors. Numerous studies have demonstrated the significant association between the JAK-STAT signaling pathway and numerous diseases, particularly autoimmune diseases such as rheumatoid arthritis, intestinal diseases, and allergic diseases. Therefore, these protein kinases have become crucial drug development targets for disease intervention. Currently, many pharmaceutical companies are developing new drugs targeting members of the JAK family, but most focus on inhibiting JAK1 and JAK3, with very few reports on inhibitors targeting Tyk2.
[0003] The JAK-STAT pathway can be activated by more than 50 different cytokines. Pro-inflammatory cytokines (IL6, TNF-α, IL12, IL23), anti-inflammatory cytokines (IL4, IL10), hematopoietic growth factors (g-CSF, EPO, TPO), and metabolic cytokines (leptin, GH) can activate this signaling pathway, thereby regulating cell proliferation, differentiation, and activation, as well as the transcriptional regulation of various genes involved in human metabolic homeostasis. The JAK / STAT cascade is a convergence point for many extracellular regulatory signals, making it a central communication node in the cell. Studies have shown that cytokine-mediated signal transduction systems activate JAK family members JAK1, JAK2, JAK3, and TYK2 tyrosine kinases, phosphorylate cytokine receptors, recruit STAT (signal transducer and activator of transcription proteins), and ultimately lead to intracellular gene expression. The pairing between JAK members is directly related to upstream cytokines. Depending on the specific cytokine stimulation, upstream cytokine signals may exhibit different pairings, such as JAK1 / JAK2, JAK1 / JAK3, JAK1 / TYK2, JAK2 / TYK2, and JAK2 / JAK2, with JAK1 pairing being the most common. TYK2 is crucial for the signal transduction of type I interferons (IFN-alpha, IFN-beta), IL-6, and IL-23. Immune cell differentiation and function associated with inflammatory and autoimmune diseases are significantly related to TYK2. Typically, TYK2 and its family members, upon activation by the signal transduction system, may appear in pairings such as TYK2 / JAK1, TYK2 / JAK2, and TYK2 / JAK1 / JAK2. TYK2 plays a vital role in mediating the signal transduction pathways of IL-12, IL-17, and IL-23. Biological antibody drugs targeting IL17 and IL23 have achieved good therapeutic effects on diseases such as psoriasis. It is conceivable that by using highly efficient small molecules to inhibit JAK kinase activity, especially TYK2 kinase activity, it is possible to block the signaling pathway mediated by inflammatory factors, control inflammation, effectively treat autoimmune diseases and / or inflammatory skin diseases, and reduce side effects.

[0685] Experiment to identify the inhibitory effect of compounds on JAK kinase
[0686] Janus kinases (JAKs) include JAK1, JAK2, JAK3, and Tyk2, which transduce cytokine-mediated signals via the JAK-STAT pathway. The kinases are 120-140 kDa in size and have seven defined homologous regions, JH1-JH7. JH1 is a crucial region for enzyme activity, containing typical tyrosine kinase characteristics. Phosphorylation of tyrosine residues leads to a conformational change in the JAK protein, thereby promoting substrate binding. The JAK-STAT system comprises three main parts: a receptor that crosses the cell membrane, a Janus kinase attached to the receptor, and a signal transducer and activator of transcription (STAT) that transmits signals to the nucleus and DNA. When a cytokine binds to its receptor, JAK phosphorylates the receptor, attracting STAT proteins. The STAT proteins are also phosphorylated and bind to each other to form a dimer. The dimer enters the nucleus and binds to DNA, leading to gene transcription.
[0687] PerkinElmer's EZ Reader can be used to detect phosphorylation of peptide substrates catalyzed by kinases. This device, based on microfluidic separation technology, can directly detect fluorescently labeled substrates and products. The separation step is achieved within a microfluidic chip by controlling pressure and electric field strength. Kinase assays are typically performed with a product conversion rate of 20-30%. This biological assay method is used to identify the inhibitory effect of compounds on JAK.
