Abstract
Description
[Technical field]
[0001] The present disclosure is in the field of pharmaceutical technology and relates to quinazoline compounds, their compositions and applications. [Background technology]
[0002] Epidermal growth factor receptor (ErbB) tyrosine kinase can regulate cell proliferation, migration, differentiation, apoptosis, and cell motility through multiple pathways. ErbB family members and some of their ligands are commonly overexpressed, amplified, or mutated in many forms of malignant tumors, making them important therapeutic targets. This protein kinase family includes ErbB1 / EGFR / HER1, ErbB2 / HER2, ErbB3 / HER3, and ErbB4 / HER4, among which EGFR and HER2 are important targets for the development of drugs against non-small cell lung cancer and breast cancer (Non-Patent Document 1, Non-Patent Document 2). Currently, several generations of EGFR and HER2 kinase inhibitors are also commercially available.
[0003] However, the expression of EGFR and HER2 is not stable, and gene amplification and rearrangement occur frequently, which leads to changes in the antigen phenotype on the surface of tumor cells. The effectiveness of existing targeted drugs against various mutations of EGFR and HER2 varies greatly, with the weakest inhibitory ability against Ins20, which leads to drug-resistant mutations against which existing multi-generation targeted drugs are largely ineffective. Although the exon 20 mutations of the EGFR gene and the HER2 gene occur at similar positions, there are many types of EGFR exon 20 insertion mutations, of which 122 types have been found. In contrast, there are fewer types of exon 20 insertion mutations in the HER2 gene, the most common of which is the A775_G776insYVMA site, accounting for nearly 70% of the total number of mutations. Statistics also show that about 3% of NSCLC patients have HER2 mutations, and about 90% are patients with exon 20 mutation types of the HER2 gene. In these EGFR / HER2 exon 20 mutation patients, the effectiveness of existing targeted TKI drugs is very limited.
[0004] Meanwhile, there are a few research projects targeting EGFR / HER2 Ins20 mutations. Poziotinib is a broad-spectrum HER inhibitor developed by Hanmi. Clinical data shows that poziotinib has some efficacy against EGFR / HER2 exon 20 mutations, but has a high incidence of side effects. At the same time, the commercially available pyrotinib is also undergoing clinical studies for the relevant exon 20 mutations.
[0005] In addition, EGFRvIII, a mutant class of epidermal growth factor receptor EGFR that is expressed only on the surface of tumor cells and not on the cell surface of normal tissues, has also been identified in recent years, and is also a very common EGFR mutant. In contrast to the intact structure of EGFR, exons 2-7 encoding the extracellular ligand-binding region of EGFRvIII are deleted, resulting in a deletion of 801 base pairs that joins exons 1 and 8, and creates a new glycine at this binding site, causing a deletion of amino acids 6-273, which results in a loss of the ability to bind the ligand EGF. In the absence of ligand binding, EGFRvIII constitutively activates tyrosine kinases in a disordered manner by dimerization and autophosphorylation, inducing downstream signaling and stimulating tumor cell proliferation. Therefore, the development of new molecular targeted therapeutics against EGFRvIII would provide more effective and cost-effective treatment options for tumor patients, and there is a huge unmet clinical need.
[0006] From the viewpoint of chemical structure, many TKI drugs on the market, as well as the above-mentioned poziotinib and pyrotinib, are all derived from the structure of quinazoline or quinoline. As shown in the figure below, when constructing a TKI inhibitor via quinazoline or quinoline, an aniline-based group is usually introduced at the 4th position, and the 6th and 7th positions are substituted at the same time. Pyrotinib, neratinib, and poziotinib shown in the figure below are all substituted with an alkoxy group at the 7th position, and also have a substituent at the 6th position. However, there have been few attempts to construct a TKI inhibitor by substitution at the 5th position. In this application, a series of quinazoline compounds are synthesized by introducing a substituent at the 5th position and removing the substituent at the 7th position, which show excellent inhibitory activity against HER2 and its exon 20 mutation, and are expected to be used for the treatment of HER2 exon 20 mutation.
[0007] Of particular note is that none of the currently available small molecule HER2 inhibitors can effectively cross the blood-brain barrier, and approximately 50% of HER2-positive breast cancer patients develop brain metastasis. Considering that some compounds of the present application can effectively cross the blood-brain barrier and have extremely strong inhibitory effects on HER2-positive tumors, it is expected that the compounds of the present application can also be used to treat patients with brain metastasis from HER2-positive breast cancer.

[0080] The term "carbonyl" refers to the group -C(O)-. The terms "halogen" and "halo" refer to chlorine, fluorine, bromine, or iodine substituents. "Oxo" refers to an oxygen moiety containing a double bond, for example, "oxo" may be attached directly to a carbon atom to form a carbonyl moiety (C=O). "Hydroxy" is intended to refer to the radical -OH. As used herein, the term "cyano" refers to the group: -CN.
[0081] The term "deuterated derivatives" refers, in some cases, to derivatives obtained by deuteration of one or more hydrogen atoms in the compounds of the present application.
[0082] The term "independently" means that when multiple substituents are selected from a number of possible substituents, the substituents may be the same or different.
[0083] It is clear that the compound of formula I, or its stereoisomer, crystalline form, or prodrug, and its pharma- ceutically acceptable salt, may exist in solvated or non-solvated form.For example, the solvated form may be a water-soluble form.The present disclosure includes all solvated and non-solvated forms.
[0084] In this disclosure, the term "isomer" refers to different compounds having the same molecular formula and may include various isomeric forms such as stereoisomers and tautomers. "Stereoisomers" are isomers that differ only in the spatial arrangement of their atoms. Some compounds described herein contain one or more asymmetric centers and can therefore give rise to enantiomers, diastereomers, and other stereoisomeric forms that may be defined as (R) or (S) forms based on absolute stereochemistry. The chemical compounds, pharmaceutical compositions, and methods disclosed herein are intended to include all of these possible isomers, including racemic mixtures, optically pure forms, and mixtures therebetween. Optically active (R) and (S) isomers can be prepared using chiral synthons or chiral reagents or resolved using conventional techniques. The optical activity of a compound can be analyzed by any suitable method, including but not limited to chiral chromatography and polarimetry, to determine the predominance of one stereoisomer over the other.
[0085] Individual stereoisomers (or isomer-enriched mixtures) of the compounds of the present disclosure may be resolved using methods known to those of skill in the art. For example, such resolution may be carried out by (1) formation of a diastereoisomeric salt, complex, or other derivative; (2) selective reaction with a stereoisomer-specific reagent, such as by enzymatic oxidation or reduction; or (3) by gas-liquid or liquid chromatography in a chiral environment, such as on a chiral support such as silica bound to a chiral ligand, or in the presence of a chiral solvent. Those skilled in the art will recognize that when the desired stereoisomer is converted to another chemical entity by one of the above-mentioned separation procedures, an additional step is required to liberate the desired form. Alternatively, a particular stereoisomer may be synthesized by asymmetric synthesis using optically active reagents, substrates, catalysts, or solvents, or by converting one enantiomer to the other by asymmetric transformation.
[0086] When the compounds described herein contain olefinic double bonds, unless otherwise specified, the compounds are meant to include various cis and trans isomers.
[0087] "Tautomers" are structurally distinct isomers that are interconvertible by tautomerization. "Tautomerization" is a form of isomerization and includes prototropic change tautomerization or proton transfer tautomerization, which can be considered part of acid-base chemistry. "Prototropic change tautomerization" or "proton transfer tautomerization" involves the migration of a proton with a change in bond level, often the exchange of a single bond with an adjacent double bond. When tautomerization is possible (e.g., in solution), the tautomers may reach chemical equilibrium. One example of tautomerization is keto-enol tautomerization.
[0088] The compounds of the present disclosure as active ingredients and their preparation methods are both included in the present disclosure.In addition, the crystalline forms of some compounds may exist as crystalline polymorphs, and such forms are also included in the present disclosure.In addition, some compounds may form solvates with water (i.e., hydrates) or with common organic solvents, and such solvates are also included in the scope of the present disclosure.

Tables 8 to 11 show the values of each pharmacokinetic parameter of pyrotinib, neratinib, control compounds 1 and 2, and some compounds of the present application, both under intravenous injection and oral administration, respectively. The results show that control compounds 1 and 2 are hardly absorbed when orally administered, and effective pharmacokinetic data cannot be obtained because they are not measurable, but all of the compounds of the present application exhibit excellent pharmacokinetic properties and are superior to pyrotinib and neratinib in terms of bioavailability.
[0263] [Table 9]
[0264] [Table 10]
[0265] [Table 11]
[0266] [Table 12]
[0267] Meanwhile, as shown in Table 11-1 below, the compounds of the present application exhibit excellent ability to pass through the blood-brain barrier, and the brain / blood ratio is significantly increased compared with pyrotinib and neratinib. This further indicates that the compounds of the present application not only have excellent inhibitory activity against EGFR and HER2 kinase, but also have excellent ability to pass through the blood-brain barrier, and therefore the compounds of the present application are expected to be applied to related tumors mediated by EGFR and / or HER2 kinase, especially brain metastasis.

[0269] Assay Example 4. Assaying the efficacy of small molecule compounds in tumor-bearing mice In this assay, several compounds of the present application were orally administered to a Ba / F3 ERBB2 A775_G776insYVMA tumor-bearing nude mouse model to examine the effect of the compounds of the present application on tumor growth.
[0270] [Table 14]
[0271] [Table 15]
[0272] Reagents: RPMI1640 (ThermoFisher, Cat. No. C11875500BT); Fetal Bovine Serum (Hyclone, Cat. No. SV30087.03); 0.25% Trypsin-EDTA (ThermoFisher, Cat. No. 25200072); Penicillin-Streptomycin (Hyclone, Cat. No. SV30010); DSMO (Life Science, Cat. No. 0231-500ML); Solutol (Sigma, 70142-34-6-1kg)
[0273] Preparation of assay compounds: An appropriate amount of the compound to be assayed was weighed out and completely dissolved in an appropriate amount of vehicle (DMSO). The mixture was vortexed or sonicated. An appropriate amount of Solutol was then added and mixed thoroughly. Finally, sterile drinking water was added and the mixture was mixed by stirring or vortexing to obtain a homogenous solution or suspension.
[0274] Methods: All assays were approved and agreed to by the Animal Welfare Committee. Exponentially growing Ba / F3 ERBB2 A775_G776insYVMA were inoculated into the right back of immunodeficient nude mice (BALB / c nude, female, 6-7 weeks old, weighing 18 ± 2 g) at 4 × 10 6 Cells were inoculated subcutaneously per rat. Tumors were 150–200 mm 3 After the animals had grown to 100 mm Hg, they were randomly divided into treatment and control groups. The treatment groups received a solution of each assay compound, and the control group received a vehicle solution without the assay compound. Both treatment and control groups were dosed once a day for approximately 2 weeks. The dose of each assay product was 30 mg / kg (calculated as the effective compound concentration), and all assay compounds were freshly prepared. During the assay, the diameter of the tumor was measured twice a week, and the body weight of the mice was also measured. Tumor volume (TV) was calculated according to the formula: TV=1 / 2×a×b 2 (wherein a and b refer to length and width, respectively). Based on the measurement results, the relative tumor volume (RTV) was calculated by the formula: RTV=Vt / V0 (wherein V0 is the tumor volume measured at the time of grouping and administration, and Vt is the tumor volume at each measurement). The evaluation index of antitumor activity is the relative tumor growth rate T / C(%) calculated by the formula: T / C(%)=(TRTV / CRTV)×100% (TRTV: RTV of the administration group; CRTV: RTV of the control group). T and C refer to the average tumor volume at a certain time point in the administration group and the control group, respectively.
[0275] The assay results are shown in Table 14 and Figures 1 to 9 below. As shown in the table and figures, neratinib and pyrotinib have a certain tumor inhibitory effect at a dose of 30 mg / kg, and the T / C values on the 14th day are 45.9% and 38.3%, respectively. The compounds of Example 4, Example 8, Example 9, Example 11, Example 24, Example 29, and Example 33 of the present application have a remarkable tumor inhibitory effect at a dose of 30 mg / kg, and the T / C values on the 14th day of the compounds of Example 4 and Example 24 are 2.6% and 12.4%, respectively, the T / C values on the 15th day of the compounds of Example 8, Example 9, and Example 11 are 5.83%, 3.85%, and 5.71%, respectively, and the T / C values on the 11th day of the compounds of Example 29 and Example 33 are 18.7% and 12.4%, respectively. Combined with the results of the above-mentioned Ba / F3 HER2 A775-G776sYAMA cell proliferation activity assay, the compounds of the present application not only have better in vitro antitumor cell proliferation activity against HER2 exon 20 insertion mutation (HER2 A775_G776insYVMA) than pyrotinib and neratinib, but also have much better antitumor activity than neratinib and pyrotinib in Ba / F3 ERBB2 A775_G776insYVMA tumor-bearing nude mouse model. All assayed compounds achieve significant tumor shrinkage, but the tumors in the neratinib group and pyrotinib group still maintain significant growth at the same dose (30mg / kg).
[0276] [Table 16]
[0277] Taking all the assay results together, it can be seen that the present application synthesizes a series of compounds by introducing a substituent at the 5-position of quinazoline and removing the substituent at the 7-position. The compounds of the present application exhibit good to excellent inhibitory activity against HER2 and EGFR kinase, as well as good to excellent inhibitory activity against the proliferation of BT474, NCI-N87, Ba / F3-EGFR-VIII, Ba / F3 HER2 A775_G776insYVMA, and Ba / F3 EGFR D770_N771insSVD cells. In particular, all the compounds of the present application exhibited excellent inhibitory activity against the proliferation of Ba / F3 HER2 A775_G776insYVMA cell model. Vitro Cell proliferation inhibition assay and Bibo In tumor-bearing model assay, the compound of the present application exhibits significantly better effect than neratinib and pyrotinib.In addition, the compound of the present application also shows excellent pharmacokinetic properties in pharmacokinetic assay.The overall performance of the compound of the present application is significantly better than neratinib, pyrotinib, and control compounds 1 and 2, and the compound of the present application can be applied in the treatment of related diseases mediated by HER2, EGFR kinase, or its exon 20 mutation, or other mutations.
