Abstract
Description
Technical Field
[0001] This invention belongs to the field of pharmaceutical technology and relates to a quinazoline compound, a composition, and its application. Background Technology
[0002] Epidermal growth factor receptor (ErbB) tyrosine kinases regulate cell proliferation, migration, differentiation, apoptosis, and cell movement through multiple pathways. In various forms of malignant tumors, ErbB family members and some of their ligands are often overexpressed, amplified, or mutated, making them important targets for cancer therapy. This family of protein kinases includes ErbB1 / EGFR / HER1, ErbB2 / HER2, ErbB3 / HER3, and ErbB4 / HER4. Among these, several kinase inhibitors based on EGFR and HER2 have been successfully developed for the treatment of non-small cell lung cancer and breast cancer. (Dienstmann R.,et.al.,(2001)PersonalizingTherapy with Targeted Agents in Non-Small Cell Lung Cancer.ONCOTARGET.2(3),165.;Mitri Z.,et.al.(2012)The HER2 Receptor in Breast Cancer: Pathophysiology,Clinical Use,and New Advances in Therapy.,Chemotherapy Research&Practice.,Volum 2012(23),743193.).
[0003] EGFR is widely expressed and plays a vital role in growth, development, and normal physiological functions. Furthermore, EGFR and its mediated signaling pathways also play a crucial role in tumorigenesis and development. However, EGFR expression is highly unstable, frequently exhibiting gene amplification and rearrangement, leading to alterations in the antigenic phenotype of tumor cells. The most common of these alterations is the epidermal growth factor receptor variant III (EGFRvIII).
[0004] EGFRvIII is a class of mutants of the epidermal growth factor receptor (EGFR) discovered in recent years that are expressed only on the surface of tumor cells, not normal tissue cells. Aberrant expression of EGFR is associated with the development of many malignant tumors, including glioma, small cell lung cancer, breast cancer, bladder cancer, and ovarian cancer.
[0005] Compared to the intact EGFR structure, exons 2-7 encoding the extracellular ligand-binding region of EGFRvIII are deleted, resulting in an 801-base pair loss. This causes exons 1 and 8 to connect, and a new glycine residue is created at this binding site, leading to the deletion of amino acids 6-273, thus losing the ability to bind to the ligand EGF. Without ligand binding, EGFRvIII induces unregulated structural activation of tyrosine kinases via dimerization and autophosphorylation, triggering downstream signaling and stimulating tumor cell proliferation.
[0006] Previous studies have shown that EGFRvIII can influence tumorigenesis and development by regulating multiple signaling pathways, including Ras / Raf / MEK / ERK, PI3 / AKT / mTOR, JAK / STAT, and PLC / PKC. EGFRvIII-positive tumor cells exhibit significantly increased tumorigenicity, primarily through inhibiting apoptosis, promoting tumor angiogenesis, and increasing invasiveness and migration, leading to uncontrolled spontaneous proliferation and metastasis of tumor cells. Furthermore, EGFRvIII plays a similar escape-like role during radiotherapy and chemotherapy for tumors.
[0007] Gliomas are common and highly aggressive malignant tumors, with glioblastoma (GBM) being the most malignant type. The effects of radiotherapy and chemotherapy are not ideal, and recurrence is common after surgery. Domestic and international studies have found that 40%–60% of GBMs significantly express EGFR, with the EGFRvIII mutant form being the predominant one. EGFRvIII, through receptor-independent autophosphorylation and tyrosine kinase activity, establishes a signaling pathway regulatory network, playing a crucial role in regulating GBM growth, metastasis, and angiogenesis.
[0008] Recent studies have shown that molecularly targeted therapies against EGFRvIII have demonstrated promising anti-tumor effects in both in vitro cell culture and in vivo animal models. Therefore, developing new molecularly targeted therapies against EGFRvIII will provide cancer patients, especially those with gliomas, with more effective and cost-effective treatment options, representing a significant unmet clinical need.
[0009] Drugs targeting EGFRvIII for the treatment of gliomas need to not only effectively cross the blood-brain barrier but also effectively inhibit EGFRvIII. Currently, there are no reports of compounds that can both cross the blood-brain barrier and inhibit EGFRvIII; therefore, research on EGFRvIII-driven gliomas has significant clinical value. Furthermore, most marketed EGFR and HER2 kinase inhibitors cannot cross the blood-brain barrier, and patients with EGFR-driven lung cancer and HER2-driven breast cancer generally have poor prognoses and a high risk of brain metastases. Currently, there are no approved effective drugs for the treatment of brain metastases; therefore, there is an urgent need to develop an EGFR inhibitor and / or HER2 inhibitor that can cross the blood-brain barrier.

In this application, unless otherwise stated, the use of “or” or “and” means “and / or”. Furthermore, the use of the term “comprising” and other forms such as “including,” “containing,” and “having” is not restrictive. Section headings used herein are for organizational purposes only and should not be construed as limiting the subject matter.
[0036] Unless otherwise specified, alkyl refers to a saturated straight-chain or branched hydrocarbon group having a specified number of carbon atoms. The terms C1-C6 alkyl refer to alkyl moieties containing 1 to 6 carbon atoms, and similarly, C1-C3 alkyl refer to alkyl moieties containing 1 to 3 carbon atoms.

[0046] The term "independently" means that when more than one substituent is selected from many possible substituents, those substituents may be the same or different.
[0047] It is clear that compounds, isomers, crystal forms, or prodrugs of Formula I, and their pharmaceutically acceptable salts, can exist in solvated and unsolvated forms. For example, the solvated form can be a water-soluble form. This invention includes all such solvated and unsolvated forms.
[0048] In this application, 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 atoms. Some compounds described herein contain one or more asymmetric centers, and therefore can produce enantiomers, diastereomers, and other stereoisomers that, according to absolute stereochemistry, can be defined as (R)- or (S)-. The chemical entities, pharmaceutical compositions, and methods of this invention are intended to include all such possible isomers, including racemic mixtures, optically pure forms, and intermediate mixtures. Optically active (R)- and (S)- isomers can be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques. The optical activity of the compounds can be analyzed by any suitable method, including but not limited to chiral chromatography and optical rotation determination, and the extent to which one stereoisomer outperforms the others can be determined.
[0049] Individual isomers (or mixtures enriched with isomers) of the present invention can be separated using methods known to those skilled in the art. For example, the separation can be performed as follows: (1) by forming diastereomer salts, complexes, or other derivatives; (2) by selective reaction with stereoisomer-specific reagents, such as by enzymatic oxidation or reduction; or (3) by gas-liquid chromatography or liquid chromatography in a chiral environment, such as on a chiral support (e.g., silica gel with chiral ligands) or in the presence of a chiral solvent. Those skilled in the art will understand that when a desired stereoisomer is converted into another chemical entity using one of the above separation methods, additional steps are required to release the desired form. Alternatively, specific stereoisomers can be synthesized by asymmetric synthesis using optically active reagents, substrates, catalysts, or solvents, or by asymmetric conversion of one enantiomer into another.
[0050] When the compounds described herein contain olefin double bonds, unless otherwise stated, it means that the compounds include various cis-trans isomers.
[0051] "Tautomers" are structurally different isomers that can interconvert through tautomerization. Tautomerization is a form of isomerization and includes proton shift or proton transfer tautomerization, which can be considered a subset of acid-base chemistry. Proton shift or proton transfer tautomerization involves proton migration accompanied by bond order changes, often involving the exchange of a single bond with an adjacent double bond. When tautomerization is possible (e.g., in solution), chemical equilibrium of the tautomers can be achieved. An example of tautomerization is keto-enol tautomerization.
[0052] The compounds of this invention, which are active ingredients, and the methods for preparing these compounds are also part of this invention. Furthermore, some compounds can exist in polycrystalline form, and this form is also included in the present invention. Additionally, some compounds can form solvates with water (i.e., hydrates) or common organic solvents, and these solvates are also included within the scope of this invention.
[0053] The compounds of the present invention can be used for treatment in their free form or, where appropriate, in the form of pharmaceutically acceptable salts or other derivatives. As used herein, the term "pharmaceutically acceptable salt" refers to organic and inorganic salts of the compounds of the present invention that are suitable for human and lower animal use, without excessive toxicity, irritation, allergic reactions, etc., and have a reasonable benefit / risk ratio. Pharmaceutically acceptable salts of amines, carboxylic acids, phosphonates, and other types of compounds are well known in the art. These salts can be formed by reacting the compounds of the present invention with a suitable free base or acid. This includes, but is not limited to, salts formed with inorganic acids such as hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid, perchloric acid, or with organic acids such as acetic acid, oxalic acid, maleic acid, tartaric acid, citric acid, succinic acid, malonic acid, or by using methods well known in the art, such as ion exchange.

[0054] Furthermore, the term "prodrug" as used herein refers to a compound that can be converted into the compound described in this invention in vivo. This conversion is influenced by the hydrolysis of the prodrug in the blood or its enzymatic conversion into the parent compound in the blood or tissues.
[0055] The pharmaceutical compositions of the present invention comprise additional active agents of the compounds described herein or pharmaceutically acceptable salts thereof, kinase inhibitors (small molecules, peptides, antibodies, etc.), immunosuppressants, anticancer drugs, antiviral agents, anti-inflammatory agents, antifungal agents, antibiotics, or antiangiogenic compounds; and any pharmaceutically acceptable carrier, adjuvant, or excipient.
[0056] The compounds of the present invention can be used alone or in combination with one or more other compounds of the present invention or with one or more other pharmaceutical agents. When administered in combination, the therapeutic agents can be formulated for simultaneous or sequential administration at different times, or the therapeutic agents can be administered as a single composition. The term "combination therapy" refers to the use of the compounds of the present invention in conjunction with another pharmaceutical agent, administered either simultaneously or sequentially, with the aim of achieving optimal drug efficacy. Co-administration includes simultaneous delivery formulations as well as separate formulations for each compound. Therefore, the administration of the compounds of the present invention can be used concurrently with other known therapies in the art, such as in cancer treatment using radiotherapy or adjunctive therapies such as cell growth inhibitors, cytotoxic agents, or other anticancer agents to improve cancer symptoms. The present invention is not limited to the order of administration; the compounds of the present invention can be administered prior to, concurrently with, or after other anticancer agents or cytotoxic agents.
