Abstract
Description
Detailed Description of the Invention
[0001] [Technical field] The present invention relates to the field of small drug molecules, and specifically, the present invention provides prodrug compounds as kinase inhibitors, and pharmaceutically acceptable salts, hydrates, or solvates thereof, as well as pharmaceutical compositions (preferably topical formulations) containing the above components.
[0002] [Background technology] The JAK-STAT signaling pathway is a recently discovered cytokine-stimulated signaling pathway. JAKs play an important role in cytokine signaling, and downstream substrates of the JAK kinase family include signal transducers and activators of transcription (STAT) proteins. JAK proteins are important members of this pathway, and abnormally elevated activity often leads to the development of diseases. Many diseases are associated with abnormal cellular responses of the JAK-STAT signaling pathway, including autoimmune diseases, inflammatory diseases, bone diseases, metabolic diseases, neurological and neurodegenerative diseases, cancer, cardiovascular diseases, allergic reactions and asthma, and Alzheimer's disease.
[0003] Rheumatoid arthritis (RA) is a common chronic autoimmune disease characterized by joint swelling, pain, stiffness, deformity, and severe functional impairment. Its human incidence rate is 0.5%–1.0%. Because the pathogenesis of RA remains unclear, its pathological process is difficult to control, resulting in a high disability rate, severely damaging patients' physical and mental health, and reducing their quality of life. Currently, medications used to treat RA primarily include nonsteroidal anti-inflammatory drugs (NSAIDs), disease-modifying antirheumatic drugs (DMARDs), and antibody-based drugs. DMARDs have long been the first-line treatment for RA. In 1988, the first DMARD, methotrexate (MTX), was approved by the FDA for the treatment of RA, marking a significant milestone in RA treatment. While these drugs are widely used due to their efficacy, tolerability, and safety, they also have side effects such as nausea, vomiting, gastric discomfort, and hepatotoxicity. On the other hand, recently developed antibody-based drugs have good therapeutic effects and safety indicators for moderate to severe RA, but because they target specific cytokines, the number of people who can benefit is clearly limited. In addition, the treatment costs and the injection-based drug administration method also limit the widespread use of these drugs.
[0004] Over the past 20 years, RA treatment has made considerable progress, and existing treatments have been able to effectively control patients' symptoms. Nevertheless, RA patients still suffer from problems such as disease recurrence, less than ideal treatment efficacy, poor long-term tolerance, and adverse reactions. More importantly, the quality of life of RA patients, including organ function such as joints, has not been truly improved by current treatments, so focusing on restoring patients' normal functions remains a huge unmet clinical need in this field.
[0005] Research has shown that the core role in the development of RA is played by the autocrine production of large amounts of cytokines by monocytes / macrophages and lymphocytes that infiltrate into RA synovial tissue and cells, and these cytokines interact with each other and activate the JAK / STAT signaling pathway (Janus kinase / Signal transducer and activators of transcription signaling pathway) through different pathways. Specific inhibition of the JAK / STAT signaling pathway can block the cascade amplification of the above cytokines, thereby improving the damaged joint symptoms of RA patients. Therefore, the JAK / STAT signaling pathway is a potential target for RA treatment.
[0006] Because JAK kinases are involved in various important physiological processes in the body, broad inhibition of various subtypes may produce adverse reactions. Tofacitinib has been used in patients with moderate to severe RA who are intolerant or lack a sufficient response to MTX. Clinical trials have shown that certain adverse reactions, including infection, tuberculosis, tumors, anemia, liver damage, and elevated cholesterol, are associated with this treatment. Tofacitinib exhibits significant inhibitory activity against all JAK1, JAK2, and JAK3 subtypes. Since JAK2 activity is involved in erythrocyte differentiation and lipid metabolism, some of these side effects may be related to the drug's nonselective inhibition. Therefore, the search for selective inhibitors of JAK1 and / or JAK3 represents a new direction in RA drug research. Currently, JAK inhibitors have been demonstrated to be useful as treatments for blood disorders, tumors, rheumatoid arthritis, and psoriasis. However, JAK inhibitor compositions available for topical administration are still very limited in this field.

[0127] Pharmaceutical compositions and methods of administration The compounds of the present invention can be metabolized in vivo after topical administration to form therapeutically active ingredients, and therefore the compounds of the present invention and their various crystalline forms, pharmaceutically acceptable inorganic or organic salts, hydrates or solvates, as well as pharmaceutical compositions containing the compounds of the present invention as a major active ingredient, are useful for the prevention and / or treatment (stabilization, alleviation or cure) of various autoimmune and inflammation-related diseases, including cancer, myeloproliferative disorders, inflammation, immune disorders, organ transplants, viral diseases, cardiovascular diseases or metabolic disorders, etc.
[0128] The pharmaceutical composition of the present invention contains a compound of the present invention in a safe and effective amount and a pharmaceutically acceptable excipient or carrier. Here, "safe and effective amount" refers to an amount of the compound sufficient to clearly improve the condition without causing serious side effects. Typically, the pharmaceutical composition contains 1 to 2000 mg, more preferably 1 to 200 mg, of the compound of the present invention per agent. Preferably, the "agent" is one capsule or tablet.
[0129] "Pharmaceutically acceptable carrier" refers to one or more compatible solid or liquid fillers or gel-like substances that must be of sufficient purity and sufficiently low toxicity to be suitable for human use. "Compatibility" means that the components in the composition are miscible with the compound of the present invention and with each other without significantly reducing the efficacy of the compound. Some examples of pharmaceutically acceptable carriers include cellulose and its derivatives (e.g., sodium carboxymethylcellulose, sodium ethylcellulose, cellulose acetate, etc.), gelatin, talc, solid lubricants (e.g., stearic acid, magnesium stearate, etc.), calcium sulfate, vegetable oils (e.g., soybean oil, sesame oil, peanut oil, olive oil, etc.), polyhydric alcohols (e.g., propylene glycol, glycerin, mannitol, sorbitol, etc.), emulsifiers (e.g., Twen®, etc.), wetting agents (e.g., sodium dodecyl sulfate, etc.), colorants, flavoring agents, stabilizers, antioxidants, preservatives, pyrogen-free water, etc.
[0130] The prodrug compounds of the present invention can be easily prepared into pharmaceutical compositions containing one or more compounds of the present invention and a pharmaceutical carrier.Remington: The Science and Practice of Pharmacy, 19th Edition (Easton, PA, Mack Publishing Co., 1995), which discloses typical carriers and general methods for preparing pharmaceutical compositions, can be referenced, and the methods can be used or modified as described to produce medicaments containing the compounds of the present invention.As mentioned above, the compounds of the present invention can also be administered in the form of pharmaceutical salts, etc.
[0131] The compounds of the present invention may be administered orally, parenterally, topically, rectally, nasally, buccally, or vaginally in the form of pharmaceutical formulations containing common non-toxic pharmaceutical carriers, adjuvants, and vehicles, or via implanted reservoirs. Preferably, the compounds of the present invention may be administered via the skin or mucosal tissue in a common topical administration system, in which the drug is contained in a multilayer structure that is immobilized on the skin and functions as an administration device. In such a configuration, the pharmaceutical composition is contained in a layer beneath an upper backing layer, i.e., a "reservoir" layer. The multilayer structure may contain a single reservoir or multiple reservoirs. In one example, the reservoir comprises a polymeric matrix of a pharmaceutical adhesive material that serves to secure the system to the skin during administration. Suitable skin adhesive materials include, but are not limited to, polyethylene, polysiloxane, polyisobutylene, polyacrylate, polyurethane, and the like. Alternatively, the drug-containing reservoir and the skin-pressure adhesive can be present as separate, distinct layers, with the adhesive underlying the reservoir, which may be a polymeric matrix as described above, a liquid or hydrogel reservoir, or other form.
[0132] Of these multiple layers, the backing layer, which is the top surface of the device, functions as the main component of the multi-layer structure and provides considerable flexibility to the device. The material selected for use as the backing material should be substantially impermeable to the active substance and other substances present. The backing preferably comprises a sheet or film of a flexible, elastic material. Examples of polymers suitable for use as the backing layer include polyethylene, polypropylene, polyester, etc.
[0133] The multilayer structure includes a release layer during storage and before use. Before use, this layer is removed from the device, exposing the bottom surface or drug reservoir or another pressure-sensitive adhesive layer, allowing the system to be secured to the skin. The release layer should be made of a material that is impermeable to the drug / excipients.
[0134] The topical administration device can be manufactured by common techniques known to those skilled in the art, such as by pouring a fluid mixture of adhesive, drug, and excipients onto a backing layer, followed by lamination of a release layer. Similarly, an adhesive mixture can be poured onto a release layer, followed by lamination of a backing layer. Alternatively, a drug substance can be made without drug or excipients and then filled with a drug / excipient mixture by dipping.
[0135] The multi-layered topical administration system of the present invention may further comprise a skin penetration enhancer. That is, the inherent permeability of skin to certain drugs may be too low to allow therapeutic levels of the drug to penetrate significant areas of intact skin, and therefore a skin penetration enhancer must be administered along with these drugs. Suitable enhancers are known in the art, including, for example, dimethyl sulfoxide (DMSO), dimethylformamide (DMF), N,N-dimethylacetamide (DMA), decylmethyl sulfoxide (C10MSO), C2-C6 alkanediols, and 1-substituted azepan-2-ones, alcohols, and the like.
[0136] The compounds of the present invention can be administered alone or in combination with other pharmaceutically acceptable therapeutic agents. The pharmaceutical compositions of the invention, when administered in combination, may further comprise one or more (two, three, four or more) other pharmaceutically acceptable therapeutic agents, which may be used simultaneously, separately or sequentially with the compounds of the invention for the prevention and / or treatment of cytokine and / or interferon-mediated diseases.
[0137] When using the pharmaceutical composition, a safe and effective amount of the compound of the present invention is administered to a mammal (e.g., human) in need of treatment, and the dosage at the time of administration is a dosage considered to be pharmaceutically effective, and the daily dosage for a human weighing 60 kg is usually 1 to 2000 mg, preferably 1 to 500 mg. Of course, the specific dosage should also take into account factors such as the route of administration and the patient's health condition, all of which are within the skill of a skilled physician.
[0138] The present invention will be further described below with reference to specific examples. It should be understood that these examples are only used to illustrate the present invention and are not used to limit the scope of the present invention. Experimental methods for which specific conditions are not described in the following examples generally follow standard conditions or conditions suggested by manufacturers. Unless otherwise specified, percentages and parts are by weight.
