Description

Pyrimidopyridone or pyridopyridone compound and application thereof

Technical Field

The invention relates to the field of chemical medicine, in particular to a pyrimidopyridone or pyridopyridone compound and application thereof.

Background

The tumor molecule targeted therapy is a therapeutic method based on selectively killing tumor cells by chemical or biological means through key molecules closely related to tumor growth. The targeted therapy is characterized in that: high specificity, strong selectivity and light toxic and side effects; when used in combination, it can enhance the curative effects of traditional chemotherapy and radiotherapy and reduce postoperative recurrence. Targeted drugs represented by imatinib mesylate (STI571) (Novartis,2001), gefitinib (ZD1839) (AstraZeneca,2003), erlotinib (OSI774) (Genentech and OSIP,2004), sorafenib p-toluenesulfonate (Bay 43-9006) (Bayer and Onyx,2005), sunitinib malate (SU11248) (Pfizer,2006) and dasatinib (BMS-354825) (Bristol-Myers Squibb,2006) opened a new era for tumor chemotherapy. Tumor-targeted therapy has developed rapidly in as few as a few years. The advent of tumor-targeted therapy has impacted traditional drug delivery concepts and modalities, e.g., targeted drugs often fail to reach dose-limiting toxicity and maximum tolerated dose in phase I clinical trials due to low toxic side effects; satisfactory efficacy can be achieved without the need for maximum tolerated doses with targeted therapeutic agents. Tumor-targeted therapy is a hotspot and development trend of tumor therapy.

Epidermal Growth Factor Receptor (EGFR), a receptor tyrosine protein kinase, regulates cell proliferation, survival, adhesion, migration and differentiation. EGFR is over-activated or persistently activated in a variety of tumor cells, such as lung cancer, breast cancer, prostate cancer, and the like. EGFR overexpression is present in about 62% of non-small cell lung cancer patients, and inhibition of EGFR significantly improves survival in a subset of patients. In addition, EGFR small-molecule inhibitor drugs Gefitinib and Erlotinib which are marketed in 2003-2004 are already used for treating advanced non-small cell lung cancer, and further define that EGFR is an effective target for treating non-small cell lung cancer.

The first generation of EGFR small molecule inhibitors have achieved significant clinical efficacy in patients carrying EGFR sensitive mutations, prolonging their survival. However, most of the benefited patients can develop drug resistance after using the drug for 10-12 months. Of these, more than 50% of drug resistant patients (carrying EGFR sensitive mutation) develop resistance due to the T790M secondary mutation in EGFR. The EGFR with the secondary mutation of L858R/T790M has stronger affinity to ATP than the EGFR with sensitive mutation of L858R, and the first generation drugs are ATP competitive inhibitors, thus causing drug resistance.

Second generation irreversible EGFR inhibitors, although better results were obtained in preclinical studies, lack selectivity for wild-type EGFR (egfrwt) and are more toxic. Gilotrif, an EGFR irreversible inhibitor approved by the FDA in 2013, is effective in advanced NSCLC patients carrying activating EGFR mutation (L858R, del E746-A750), but still fails to address clinical resistance caused by the EGFRT790M mutation at the maximum clinically tolerated dose (MTD).

The third generation of an irreversible inhibitor, Osimertinib (AZD9291), which overcomes the resistance to EGFR T790M, was marketed under FDA accelerated approval in the us 11 months of 2015 (Cancer discovery 2014,4(9),1046-1061), which is clinically effective in treating advanced non-small cell lung Cancer patients with Epidermal Growth Factor Receptor (EGFR) T790M mutation or resistance to other EGFR inhibitors. Although the clinical treatment of the EGFRT790M mutant non-small cell lung cancer by the Osimetinib has great success, part of beneficial patients have drug resistance after 9-14 months of treatment (Nature Medicine 2015,21(6), 560-2). It was found that up to 40% of resistant patients developed Osimertinib resistance due to the (EGFR) C797S point mutation. Further mechanistic studies have shown that point mutations in (EGFR) C797S convert the cysteine at position 797 to serine, resulting in the inability of Osimertinib to form covalent bonds with target proteins, ultimately leading to drug resistance. Currently, there is no clinically effective EGFR inhibitor against the new mutation (C797S) when administered alone. Therefore, a new type of highly selective EGFR inhibitor is urgently needed to solve the problems of drug resistance and the like caused by the point mutation of (EGFR) C797S.

Detailed Description

In the compounds of the invention, when any variable (e.g. R)₁R, etc.) occur more than one time in any constituent, then the definition of each occurrence is independent of the definition of each other occurrence. Also, combinations of substituents and variables are permissible only if such combinations result in stable compounds. The line drawn from a substituent into the ring system indicates that the indicated bond can be attached to any ring atom that can be substituted. If the ring system is polycyclic, it means that such a bond is only attached to any suitable carbon atom of the adjacent ring. It is to be understood that substituents and substitution patterns on the compounds of the present invention may be selected by one of ordinary skill in the art to provide compounds that are chemically stable and that can be readily synthesized by those skilled in the art and by the methods set forth below from readily available starting materials. If a substituent is itself substituted with more than one group, it is understood that these groups may be on the same carbon atom or on different carbon atoms, so long as the structure is stable. The phrase "optionally substituted with one or more substituents" is considered equivalent to the phrase "optionally substituted with at least one substituent" and preferred embodiments in this case will have from 0 to 3 substituents.

The terms "alkyl" and "alkylene" as used herein are intended to include both branched and straight chain saturated aliphatic hydrocarbon groups having the specified number of carbon atoms. For example, "C₁-C₅Alkyl radical "middle" C₁-C₅The definition of "includes groups having 1,2,3, 4, or 5 carbon atoms in a linear or branched arrangement. For example, "C₁-C₅Alkyl "specifically includes methyl, ethyl, n-propyl, isopropyl, n-butyl, tert-butyl, isobutyl, pentyl. The term "cycloalkyl" refers to a monocyclic saturated aliphatic hydrocarbon group having the specified number of carbon atoms. For example, "cycloalkyl" includes cyclopropyl, methyl-cyclopropyl, 2-dimethyl-cyclobutyl, 2-ethyl-cyclopentyl, cyclohexyl, and the like.

The term "heteroaryl" as used herein represents a stable monocyclic ring of up to 6 atoms in the ring or a bicyclic carbon ring of up to 6 atoms in each ring, wherein at least one ring is aromatic and contains 1-4 heteroatoms selected from O, N and S. Heteroaryl groups within the scope of this definition include, but are not limited to: imidazolyl, triazolyl, pyrazolyl, furyl, thienyl, oxazolyl, isoxazolyl, pyrazinyl, pyridazinyl, pyridyl, pyrimidinyl, pyrrolyl. For the following definition of heteroaryl, "heteroaryl" is also understood to include any N-oxide derivative of a nitrogen-containing heteroaryl group. In the case where the heteroaryl substituent is bicyclic and contains one ring that is non-aromatic or contains no heteroatoms, it is understood that each is attached via an aromatic ring or via a heteroatom-containing ring.

The term "heterocycle" or "heterocyclyl" as used herein refers to a 5-to 6-membered aromatic or nonaromatic heterocycle containing 1to 4 heteroatoms selected from O, N and S and includes bicyclic groups. "Heterocyclyl" thus includes the above-mentioned heteroaryl groups, as well as the dihydro and tetrahydro analogues thereof. Further examples of "heterocyclyl" include, but are not limited to: imidazolyl, indolyl, isothiazolyl, isoxazolyl, oxadiazolyl, oxazolyl, oxetanyl (oxyethanyl), pyranyl, pyrazinyl, pyrazolyl, pyridazinyl, pyridyl, pyrimidinyl, pyrrolyl, quinoxalinyl, tetrazolyl, thiadiazolyl, thiazolyl, thienyl, triazolyl, l, 4-dioxanyl, pyrrolidinyl, dihydroimidazolyl, dihydroisoxazolyl, dihydroisothiazolyl, dihydrooxadiazolyl, dihydrooxazolyl, dihydropyrazinyl, dihydropyrazolyl, dihydropyridinyl, dihydropyrimidinyl, dihydropyrrolyl, dihydrotetrazolyl, dihydrothiadiazolyl, dihydrothiazolyl, dihydrothienyl, dihydrotriazolyl, dihydroazetidinyl, tetrahydrofuryl and tetrahydrothienyl, and N-oxides thereof. Attachment of the heterocyclic substituent may be through a carbon atom or through a heteroatom. In one embodiment, the heterocycle is selected from the group consisting of imidazolyl, pyridyl, 1-pyrrolidone, 2-piperidone, 2-pyrimidone, 2-pyrrolidone, thienyl, oxazolyl, triazolyl, isoxazolyl.

As understood by those skilled in the art, "halo" or "halogen" as used herein is meant to include chloro, fluoro, bromo, and iodo.

Unless otherwise defined, alkyl, cycloalkyl, aryl, heteroaryl, and heterocyclyl substituents may be unsubstitutedOr substituted. For example, (C)₁-C₆) Alkyl groups may be substituted with one, two or three substituents selected from OH, halogen, alkoxy, dialkylamino or heterocyclyl, e.g. morpholinyl, piperidinyl and the like.

The invention includes the free forms of the compounds of formulae I-VI, as well as pharmaceutically acceptable salts and stereoisomers thereof. Some specific exemplary compounds herein are protonated salts of amine-based compounds. The term "free form" refers to the amine compound in a non-salt form. Included pharmaceutically acceptable salts include not only exemplary salts of the particular compounds described herein, but also all typical pharmaceutically acceptable salts of the free forms of the compounds of formulas I-VI. The free form of a particular salt of the compound may be isolated using techniques known in the art. For example, the free form can be regenerated by treating the salt with a dilute aqueous solution of a suitable base, such as a dilute aqueous NaOH solution, a dilute aqueous potassium carbonate solution, dilute aqueous ammonia, and a dilute aqueous sodium bicarbonate solution. The free forms differ somewhat from their respective salt forms in certain physical properties, such as solubility in polar solvents, but for the purposes of the invention such acid and base salts are otherwise pharmaceutically equivalent to their respective free forms.

Pharmaceutically acceptable salts of the invention can be synthesized from compounds of the invention containing a basic or acidic moiety by conventional chemical methods. In general, salts of basic compounds are prepared by ion exchange chromatography or by reaction of the free base with a stoichiometric amount or excess of an inorganic or organic acid in the form of the desired salt in an appropriate solvent or combination of solvents. Similarly, salts of acidic compounds are formed by reaction with suitable inorganic or organic bases.

Thus, pharmaceutically acceptable salts of the compounds of the present invention include the conventional non-toxic salts of the compounds of the present invention formed by the reaction of a basic compound of the present invention and an inorganic or organic acid. For example, conventional non-toxic salts include those derived from inorganic acids such as hydrochloric acid, hydrobromic acid, sulfuric acid, sulfamic acid, phosphoric acid, nitric acid, and the like, as well as those prepared from organic acids such as acetic acid, propionic acid, succinic acid, glycolic acid, stearic acid, lactic acid, malic acid, tartaric acid, citric acid, ascorbic acid, pamoic acid, maleic acid, hydroxymaleic acid, phenylacetic acid, glutamic acid, benzoic acid, salicylic acid, sulfanilic acid, 2-acetoxy-monobenzoic acid, fumaric acid, toluenesulfonic acid, methanesulfonic acid, ethane disulfonic acid, oxalic acid, isethionic acid, trifluoroacetic acid, and the like.

If a compound of the invention is acidic, an appropriate "pharmaceutically acceptable salt" refers to a salt prepared by a pharmaceutically acceptable non-toxic base including inorganic and organic bases. Salts derived from inorganic bases include aluminum, ammonium, calcium, copper, ferric, ferrous, lithium, magnesium, manganic, manganous, potassium, sodium, zinc, and the like. Particularly preferred are ammonium, calcium, magnesium, potassium and sodium salts. Salts derived from pharmaceutically acceptable organic non-toxic bases including salts of primary, secondary and tertiary amines, substituted amines including naturally occurring substituted amines, cyclic amines and basic ion exchange resins such as arginine, betaine, caffeine, choline, N' -dibenzylethylenediamine, diethylamine, 2-dimethylaminoethanol, aminoethanol, ethanolamine, ethylenediamine, N-ethylmorpholine, N-ethylpiperidine, glucosamine, histidine, hydroxycobalamin, isopropylamine, lysine, methylglucamine, morpholine, piperazine, piperidine, piperdine, polyamine resins, procaine, purines, theobromine, triethylamine, trimethylamine, tripropylamine, tromethamine and the like.

Berg et al, "Pharmaceutical Salts," j.pharm.sci.' 1977: 66: 1-19 describe in more detail the preparation of the pharmaceutically acceptable salts described above and other typical pharmaceutically acceptable salts.

Since acidic moieties such as carboxyl groups deprotonated in a compound under physiological conditions may be anionic and such charge may then be balanced out by a protonated or alkylated basic moiety such as a quaternary nitrogen atom bearing a cation internally, it should be noted that the compounds of the present invention are potential internal salts or zwitterions.

In addition to standard methods known in the literature or exemplified in experimental procedures, the compounds of the invention can be prepared using reactions as shown in the following schemes. The following illustrative schemes are therefore for illustrative purposes and are not limited to the compounds listed or any particular substituents. The number of substituents shown in the schemes does not necessarily correspond to the number used in the claims and for the sake of clarity a single substituent is shown attached to the compound allowing for multiple substituents under the definition of formula I above.

The compounds of the formulae I to VI according to the invention can be synthesized by the person skilled in the art, starting from 4-chloro-2-methylthiopyrimidine-5-carbonic acid ethyl ester or 2, 4-dichloro-5-bromopyrimidine, by means of several reaction steps, in accordance with the prior art and with the general knowledge available.
