Patent Application
20220402948
The present invention is concerned with pharmaceutically active compounds, deuterated compounds (hydrogen substituted with deuterium) and pharmaceutically acceptable salts thereof, which can be used to treat or prevent diseases or medical conditions mediated by certain mutant forms of epidermal growth factor receptor (For example, L858R activating mutant, exon 19 deletion activating mutant, T790M resistant mutant and C797S resistant mutant). The present invention also relates to a pharmaceutical composition comprising the compound, and a method of using the compound, deuterated compound and their relating salts to treat diseases mediated by various forms of EGFR mutants.
Epidermal growth factor receptor (EGFR) is a kind of transmembrane glycoprotein belonging to the ErbB family of tyrosine kinase receptors. Activation of EGFR leads to autophosphorylation of receptor tyrosine kinases, which are involved in the cascade of downstream signal transduction pathway that regulate cell proliferation, differentiation, and survival. EGFR is abnormally activated by various mechanisms, such as receptor overexpression, mutation, ligand-dependent receptor dimerization, ligand-independent activation, and is related to the development of a variety of human cancers.
EGFR inhibition is one of the key targets of cancer therapy. Despite the rapid development of previous generations of EGFR-Tkis, the problem of drug resistance has also emerged with the development of drugs. Most drug resistance is due to the T790M mutation of the ATP receptor. Recently developed third-generation irreversible inhibitors for T790M, such as osimertinib, have good activity on inhibitory, but drug resistance will inevitably appear. Most drug resistance is due to the T790M mutation of the ATP receptor. Recently developed third-generation irreversible inhibitors for T790M, such as osimertinib, have good activity on inhibitory, but drug resistance will inevitably appear. C797S mutation is a kind of missense mutation in which serine replaces cysteine at site 797 of exon 20 of EGFR, and C797S is located in the tyrosine kinase region of EGFR. C797S mutation prevents osimertinib from forming covalent bonds in the ATP binding domain, thus losing its inhibitory effect on EGFR activation and resulting in drug resistance.
Early patent applications WO2018108064, WO2018115218, WO2018181777 disclosed a series of fourth-generation EGFR inhibitors, but there is still a need for EGFR C797S inhibitors with stronger activity. In the invention, the applicant discovers a kind of small molecules that can be used as the fourth-generation EGFR inhibitor, whose activity can be used to treat cancer and/or infectious diseases. These small molecules are expected to be used as drugs with stability, solubility, bioavailability, therapeutic indices and toxicity values, which are essential to develop effective drugs for human health.
The present invention relates to compounds capable of inhibiting EGFR which can be useful in the treatment of cancers and infectious diseases.
The first purpose of the invention is to provide a compound as shown in Formula I, or stereoisomer, tautomer, deuterated compound, pharmaceutically acceptable salt, prodrug, chelate, non-covalent complex or solvate thereof

In general, such methods include a step of bringing into association the active ingredient with the carrier that constitutes one or more necessary ingredients. In general, the compositions are prepared by uniformly and intimately admixing the active ingredient with liquid carriers or finely divided solid carriers or both. The product can then be conveniently prepared into the desired appearance.
Thus, the pharmaceutical compositions of this invention may include a pharmaceutically acceptable carrier compounds shown by Formula I or their tautomers, polymorphs, solvates, pharmaceutically acceptable salts and prodrugs.

Each tablet preferably contains from about 0.05 mg to about 5 g of the active ingredient and each cachet or capsule preferably containing from about 0.05 mg to about 5 g of the active ingredient. For example, a formulation intended for the oral administration to humans may contain from about 0.5 mg to about 5 g of active agent, compounded with an appropriate and convenient amount of carrier material which may vary from about 5 to about 95 percent of the total composition. Unit dosage forms will generally contain between from about 1 mg to about 2 g of the active ingredient, typically 25 mg, 50 mg, 100 mg, 200 mg, 300 mg, 400 mg, 500 mg, 600 mg, 800 mg or 1000 mg.
Pharmaceutical compositions of the present invention suitable for injectable use include sterile aqueous solutions or dispersions. Furthermore, the compositions can be in the form of sterile powders for the extemporaneous preparation of such sterile injectable solutions or dispersions. In all cases, the final injectable form must be sterile and must be effectively fluid for easy syringability. The pharmaceutical compositions must be stable under the conditions of manufacture and storage; thus, preferably should be preserved against the contaminating action of microorganisms such as bacteria and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyol (e.g., glycerol, propylene glycol and liquid polyethylene glycol), vegetable oils, and suitable mixtures thereof.
Pharmaceutical compositions of the present invention can be in a form suitable for topical use such as, for example, an aerosol, cream, ointment, lotion, dusting powder, or the like. Further, the compositions can be in a form suitable for use in transdermal devices. These formulations may be prepared, utilizing a compound represented by Formula I of this invention, or a pharmaceutically acceptable salt thereof, via conventional processing methods. As an example, a cream or ointment is prepared by admixing hydrophilic material and water, together with about 5 wt % to about 10 wt % of the compound, to produce a cream or ointment having a desired consistency.
Pharmaceutical compositions of this invention can be in a form suitable for rectal administration wherein the carrier is a solid. It is preferable that the mixture forms unit dose suppositories. Suitable carriers include cocoa butter and other materials commonly used in the art. The suppositories may be conveniently formed by first admixing the composition with the softened or melted carrier (s) followed by chilling and shaping in molds.
In addition to the aforementioned carrier ingredients, the pharmaceutical formulations described above may include, as appropriate, one or more additional carrier ingredients such as diluents, buffers, flavoring agents, binders, surface-active agents, thickeners, lubricants, preservatives (including antioxidants) and the like. Furthermore, other adjuvants can be included to render the formulation isotonic with the blood of the intended recipient. Compositions containing a compound described by Formula I, or pharmaceutically acceptable salts thereof, may also be prepared in powder or liquid concentrate form.
Generally, dosage levels on the order of from about 0.01 mg/kg to about 150 mg/kg of body weight per day are useful in the treatment of the above-indicated conditions, or alternatively about 0.5 mg to about 7 g per patient per day. For example, inflammation, cancer, psoriasis, allergy/asthma, diseases and discomforts of the immune system, and diseases and discomforts of the central nervous system (CNS), are effectively treated at the dosage levels of the drug ranging from about 0.01 to 50 mg of the compound per kilogram of body weight per day, or alternatively about 0.5 mg to about 3.5 g per patient per day.
It is understood, however, that lower or higher doses than those recited above may be required. Specific dose level and treatment regimens for any particular subject will depend upon a variety of factors, including the activity of the specific compound employed, the age, body weight, general health, sex, diet, time of administration, route of administration, rate of excretion, drug combination, the severity and course of the particular disease undergoing therapy.
