Definitions
- the invention relates to an anti-inflammatory drug for external use, in particular to a coupled compound drug and its application.
- JAK-STAT signaling pathway is a signal transduction pathway stimulated by cytokines discovered in recent years, which is involved in many important biological processes such as cell proliferation, differentiation, apoptosis and immune regulation. Many cytokines and growth factors transmit signals through the JAK-STAT signaling pathway, including IL (interleukin), GM-CSF (granulocyte/macrophage colony-stimulating factor), GH (growth hormone), EGF (epidermal growth factor), PDGF (platelet-derived factor) and IFN (interferon) and so on.
- IL interleukin
- GM-CSF granulocyte/macrophage colony-stimulating factor
- GH growth hormone
- EGF epidermal growth factor
- PDGF platelet-derived factor
- IFN interferon
- the JAK-STAT signaling pathway consists of three components, namely tyrosine kinase-associated receptors, tyrosine kinases (JAKs) and transcription factors (STATs). After the tyrosine kinase-associated receptor binds to the ligand, the JAK bound to it is activated. The activated JAK further activates the corresponding STAT protein. The activated STAT protein enters the nucleus and binds to the target gene to regulate the transcription of the gene.
- the JAK family includes JAK1, JAK2, JAK3, and TYK2. These kinases control seven different STATs, STAT1, STAT2, STAT3, STAT4, STAT5A, STAT5B, and STAT6. It is by controlling these STATs that cytokines and growth factors can control cell proliferation, differentiation, apoptosis, and immune regulation. Many diseases are caused by JAK and STAT mutations. These diseases can be effectively treated by modulating and selectively inhibiting certain JAKs.
- JAK-STAT is a relatively simple signaling pathway, it is involved in many cellular functions.
- JAK inhibitors There are dozens of JAK inhibitors currently on the market and under research.
- the vast majority of JAK inhibitor projects aim to maximize efficacy and minimize side effects by selectively inhibiting a certain JAK-STAT conduction.
- systemic administration systematic administration
- local administration of JAK inhibitors can reduce systemic side effects while enhancing efficacy.
- Many JAK inhibitor projects under research also use organ selectivity as the ultimate goal to maximize efficacy/risk.
- the purpose of the present invention is also to maximize the curative effect of skin administration and minimize systemic toxicity through external (skin) administration, combined with the optimization of compound structure.
- Many skin diseases including psoriasis, vitiligo, alopecia areata, etc., their causes and disease treatment mechanisms have been very clear.
- the regulation and control mechanism of various JAK-STATs by JAK inhibitors on the market and under research have also been very clear.
- By modifying the chemical structure of the existing known JAK inhibitors so that they can penetrate more through the protective layer of the skin the purpose of skin selective drug delivery can also be achieved.
- the structure-optimized product of a known compound has a relatively shorter development cycle, lower risk of efficacy failure, less possibility of unknown toxicity, and lower research and development costs. to be low.
- Compound structure optimization to increase compound skin penetration can change the physicochemical properties of the compound by adding non-functional groups to the structure of the known compound so that it can penetrate the protective layer of the skin more.
- This approach is also called prodrug technology. It is widely used in drug development.
- the present invention aims at the technical problem that the existing known JAK inhibitors still have high doses and side effects, and optimizes the structure of the known JAK compounds so that it can effectively achieve skin-selective drug delivery, thereby increasing the efficacy of skin diseases. Effectiveness and lower systemic dosage and side effects. That is to say, by coupling known JAK inhibitors with other small molecule compounds, structure optimization and skin-selective drug delivery can be achieved.
- the present invention provides the following technical solutions.
- the chemical bond between the linker and the JAK inhibitor is unstable in human skin, thus hydrolyzing and releasing the active ingredient, JAK inhibitor.
- the bond between the linker and the coupling small molecule is also unstable, thereby releasing the coupling small molecule.
- the linker itself has a known simple chemical structure and is non-toxic.
