Description

Aryl or heteroaryl pyridone or pyrimidone derivative and preparation method and application thereof

Technical Field

The invention belongs to the field of medicines, and particularly relates to an aryl or heteroaryl pyridone or pyrimidone derivative, and a preparation method and application thereof.

Background

Lung cancer is one of the leading causes of death in human cancers. Lung cancer can be divided into Small Cell Lung Cancer (SCLC) and non-small cell lung cancer (NSCLC) according to cell type, with NSCLC accounting for 85% of all lung cancer patients. The global NSCLC market was statistically estimated to be $ 209 billion in 2016, with the U.S. market taking up half, followed by Japan, Germany, and China. From the current trend, the market for non-small cell lung cancer is continuing to grow, and the global market is expected to reach $ 540 billion in 2023 (Nature, 2018; 553(7689):446- > 454).

At present, the main therapeutic drugs of NSCLC include chemotherapeutic drugs, molecular targeted drugs, tumor immunotherapy and the like. The chemotherapy drugs mainly comprise gemcitabine, paclitaxel, platinum drugs and the like, but the drugs generally have poor selectivity and high toxicity, so that relatively strong toxic and side effects are caused. In recent years, molecular targeted drugs gradually become research hotspots due to the obvious advantages of high selectivity, relatively small toxic and side effects, accurate treatment and the like. Existing NSCLC molecular targeted drugs include EGFR inhibitors (e.g., afatinib, gefitinib, erlotinib, lapatinib, dacomitinib, icotinib, pyrroltinib, norcetitinib (Rociletinib), ocitinib, etc.), ALK inhibitors (e.g., ceritinib, idetinib, bocatinib, loratinib, ocatinib, etc.), and VEGFR inhibitors (sorafenib, regorafenib, cabozantinib, sunitinib, doranitinib, etc.).

Within lung cancer patients, KRAS mutations are frequently detected, accounting for approximately 32% of all oncogene mutations. Wherein KRAS^G12CMutations account for 44% of all oncogene mutations within NSCLC. So far, the market has not been directed to KRAS ^G12CMutated drugs are approved for marketing.

Due to KRAS^G12CThe target proteins are pathologically associated with a variety of diseases, and there is therefore a need for novel KRAS^G12CThe inhibitor is used for clinical treatment. KRAS with high selectivity and high activity^G12CThe inhibitor may be on KRAS^G12CCancer caused by mutationThese diseases are more effective treatments, and reduce the potential for off-target effects, thus having more urgent clinical needs.

The chiral center of the invention has two S or R configurations, and is defined by the International Union of theory and applied chemistry (IUPAC) proposed in 1974. The racemic forms can be resolved by physical methods such as fractional crystallization, or by separation of the crystals by derivatization into diastereomers, or by chiral column chromatography. The individual optical isomers can be obtained from the racemates by any suitable method, including, but not limited to, conventional methods such as salt formation with an optically active acid followed by crystallization.

For purposes of the present invention, the chemical Elements are compatible with the Periodic Table of the Elements, CAS version, Handbook of Chemistry and Physics,75^thD. as defined in. The definition of a particular functional group is also described herein. In addition, the basic principles of Organic Chemistry, as well as specific functional groups and reactivities are also described in "Organic Chemistry", Thomas Sorrell, University Science Books, Sausaltito: 1999, which is incorporated by reference in its entirety.

Certain compounds of the present invention may exist in specific geometric or stereoisomeric forms. The present invention encompasses all compounds, including cis and trans isomers, R and S enantiomers, diastereomers, (D) isomer, (L) isomer, racemic mixtures and other mixtures thereof. Further, the asymmetric carbon atom may represent a substituent such as an alkyl group. All isomers, as well as mixtures thereof, are encompassed by the present invention.

According to the present invention, the mixture of isomers may contain a variety of isomer ratios. For example, in a mixture of only two isomers, the following combinations are possible: 50:50, 60:40, 70:30, 80:20, 90:10, 95:5, 96:4, 97:3, 98:2, 99:1, or 100:0, all ratios of isomers are within the scope of the invention. Similar ratios, as well as ratios that are mixtures of more complex isomers, are also within the scope of the invention, as would be readily understood by one of ordinary skill in the art.

The invention also includes isotopically-labeled compounds, equivalent to those disclosed herein as the original compound. In practice, however, it will often occur that one or more atoms are replaced by an atom having a different atomic weight or mass number. Examples of isotopes that can be listed as compounds of the invention include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, fluorine and chlorine, respectively ²H、³H、¹³C、¹¹C、¹⁴C、¹⁵N、¹⁸O、¹⁷O、³¹P、³²P、³⁵S、¹⁸F and³⁶and (4) Cl.

Certain isotopically-labelled compounds of the invention, e.g.³H and¹⁴among these, the radioactive isotope of C is useful in tissue distribution experiments of drugs and substrates. Tritium, i.e.³H and carbon-14, i.e.¹⁴C, their preparation and detection are relatively easy. Is the first choice among isotopes. In addition, heavier isotopes such as deuterium, i.e.²H, due to its good metabolic stability, may be advantageous in certain therapies, such as increased half-life in vivo or reduced dose, and therefore, may be preferred in certain circumstances. Isotopically labeled compounds can be prepared by conventional methods by substituting a readily available isotopically labeled reagent for a non-isotopically labeled reagent using the protocols disclosed in the examples.

If it is desired to design the synthesis of a particular enantiomer of a compound of the invention, it may be prepared by asymmetric synthesis or by derivatization with chiral auxiliary agents, separation of the resulting diastereomeric mixture and removal of the chiral auxiliary agent to give the pure enantiomer. Alternatively, if the molecule contains a basic functional group, such as an amino acid, or an acidic functional group, such as a carboxyl group, diastereomeric salts can be formed therewith with an appropriate optically active acid or base, and the isolated enantiomers can be obtained in pure form by conventional means such as fractional crystallization or chromatography.

Metabolites of the compounds referred to herein and pharmaceutically acceptable salts thereof, as well as prodrugs that are convertible in vivo into the structures of the compounds referred to herein and pharmaceutically acceptable salts thereof, are also encompassed by the claims herein.
