Description

[Technical Field]

[0001] The present invention relates to pyrimidine-2,4-diamine derivatives, methods for preparing the same, and pharmaceutical compositions for preventing or treating cancer, comprising the same as an active ingredient. [Background technology]

[0002] Cancer development is associated with various environmental factors, including chemicals, radiation, and viruses, as well as changes in oncogenes, tumor suppressor genes, and genes related to apoptosis and DNA repair. Recently, a better understanding of these molecular mechanisms of cancer has enabled new treatment methods and targeted anticancer therapies.

[0003] Targeted therapies are generally formulated to exert their effects by targeting molecules characteristic of cancer cells. Molecular targets include genes related to cancer cell signaling pathways, angiogenesis, the matrix, cell cycle regulators, and apoptosis. Currently, important targeted therapies used in treatment include "signaling pathway inhibitors," including tyrosine kinase inhibitors, and "angiogenesis inhibitors."

[0004] Protein tyrosine kinases have been found to play important roles in many malignant tumors. In particular, epidermal growth factor receptor (EGFR), a receptor tyrosine kinase of the erbB family, is abnormally activated in many epithelial cell tumors, including non-small cell lung cancer (NSCLC), breast cancer, glioma, head and neck squamous cell carcinoma, colorectal cancer, rectal adenocarcinoma, head and neck cancer, gastric cancer, and prostate cancer. Activation of EGFR-tyrosine kinase is known to induce sustained cell proliferation, invasion into surrounding tissues, distant metastasis, and angiogenesis, thereby increasing cell viability.

[0005] Specifically, EGFR is one of the ErbB tyrosine kinase receptor family (EGFR, HER2, ErbB3, ErbB4) and is a transmembrane tyrosine kinase having an intracellular domain containing an extracellular ligand-binding domain and a tyrosine kinase domain. When a ligand binds to the homodimeric or heterodimeric receptor, the intracellular tyrosine kinase is activated, and the signal stimulated by EGFR activates the phosphatidylinositol 3-kinase (PI3K) / AKT / mTOR, RAS / RAF / MAPK, and JAK / STAT signaling pathways (Nat Rev Cancer 2007;7:169-81).

[0006] In particular, EGFR is overexpressed in more than half of non-small cell lung cancers (NSCLCs), and many studies are being conducted on it as a treatment target. EGFR TKIs (tyrosine kinase inhibitors) that inhibit EGFR tyrosine kinase activity have been developed, and representative drugs include gefitinib (IRESSA®), erlotinib (TARCEVA®), and lapatinib (TYKERB®, TYVERB®).

[0007] Meanwhile, in 2004, it was reported that activating mutations in EGFR correlated with the response to gefitinib treatment in non-small cell lung cancer (NSCLC) (Science

[2004] Vol.304, 1497-500 and New England Journal of Medicine

[2004] ). (Vol.350, 2129-2139).

[0008] Specifically, EGFR mutations can be broadly divided into sensitizing mutations and resistance mutations. Exon 19 deletions and L858R point mutations in exon 21 are the most important sensitizing mutations, accounting for approximately 85-90%, and exon 19 deletion mutations are known to have better sensitization to TKIs. On the other hand, the T790M point mutation in exon 20 is the most important resistance mutation and is known to be found in more than 50% of patients with acquired resistance (Clin Cancer Res 2006;12:6494-6501).

[0009] Somatic mutations identified to date include point mutations in which a single nucleotide residue is modified within the expressed protein (e.g., L858R, G719S, G719C, G719A, L861Q), as well as in-frame deletions in exon 19 or insertions in exon 20 (Fukuoka et al., JCO 2003; Kris et al., JAMA 2003 and Shepherd et al., NEJM 2004).

[0010] Despite the initial clinical efficacy of gefitinib / erlotinib in NSCLC patients with EGFR mutations, most patients eventually develop advanced cancer while receiving treatment with these drugs. Early studies of recurrent specimens identified a secondary EGFR mutation, T790M, that renders gefitinib and erlotinib ineffective as inhibitors of EGFR kinase activity (Kobayashi et al., NEJM 2005 and Pao et al., PLOS Medicine 2005). Subsequent studies demonstrated that the EGFR T790M mutation was found in approximately 50% (24 / 48) of tumors originating from patients who had acquired resistance to gefitinib or erlotinib (Kosaka et al., CCR 2006; Balak et al., CCR 2006 and Engelman et al., Science 2007). These secondary gene modifications occur in patients treated with kinase inhibitors (e.g., T315I in ABL in imatinib-resistant CML) at positions similar to those of "gatekeeper" residues and their associated secondary resistance alleles.

[0011] EGFR mutations, specifically EGFR_del19 or EGFR_L858R, have long been known to be major causes of non-small cell lung cancer and head and neck cancer, leading to the development and clinical use of drugs like Iressa and Tarceva to treat them. However, when these drugs are used in patients, acquired resistance, resulting from secondary EGFR mutations based on the drug's structure, has been observed, and it has become clear that this is the primary cause of actual drug resistance. After an average of 10 months of use of first-generation EGFR inhibitors, acquired resistance called the T790M mutation, located in the gatekeeper of EGFR kinase, develops, rendering the first-generation EGFR inhibitors ineffective. In other words, a double mutation of EGFR_del19_T790M or EGFR_L858R_T790M develops, rendering conventional treatments ineffective.

[0012] Based on these facts, there is a need to develop second and third-generation drugs with superior efficacy and novel structures.

[0013] Over the past decade, various third-generation drugs demonstrating efficacy against the EGFR T790M double mutation include AZD9291 (osimertinib, Tagrisso) from the multinational pharmaceutical company AstraZeneca. However, resistance to AZD9291 has been reported to reappear after approximately 10 months, leading to a loss of its efficacy. In particular, resistance has been reported to arise from triple mutations including C797S (Thress et al., Nature Medicine 2015).

[0014] Therefore, there is a need to develop inhibitors that show relatively low inhibition of WT EGFR while simultaneously showing higher inhibition of specific EGFR activation or various resistance mutation forms.

[0015] Gefitinib, erlotinib, and afatinib, EGFR TKIs (tyrosine kinase inhibitors), are approved treatments for non-small cell lung cancer with activating mutations in EGFR kinase. However, resistance to these drugs develops rapidly, and T790M mutations in the receptor's ATP site are frequent. Therefore, while recently developed irreversible mutation-selective inhibitors show high activity against T790M mutations, their efficacy may be rendered ineffective by acquired mutations in C797, a cysteine ​​residue that forms a crucial covalent bond.

[0016] Intracellular human EGFR2, also known as HER2 / neu or ErbB2, is a tyrosine kinase receptor belonging to the human epidermal growth factor receptor (HER / EGFR / ERBB) family. It is typically involved in signaling pathways and induces cell growth and differentiation. HER2 exhibits very high structural similarity to the other three EGFR family members (EGFR, HER3, and HER4).

[0017] However, unlike other anti-cancer targets, in the case of HER2 (human epidermal growth factor 2), the ligand that binds to it is still unknown. It pairs with other HER receptors that bind to the ligand to form heterodimers and is involved in cell cycle progression, cell proliferation regulation, differentiation, and survival through various signaling pathways. In the case of antibodies targeting HER2, IgG2-type antibody therapies have been developed and are commercially available. The main therapeutic effect is not antibody-dependent cell-mediated cytotoxicity (ADCC) or complement-dependent cell-mediated cytotoxicity (CDC), but rather antibody-mediated neutralization activity.

[0018] Therefore, the inventors have been attempting to develop cancer treatment agents that inhibit multiple EGFR mutations. They found that the pyrimidine-2,4-diamine derivative according to the present invention exhibits relatively low inhibition of wild-type EGFR and high inhibitory activity against EGFR mutations and HER2 mutations, making it advantageous for the prevention or treatment of cancer. Based on the above, the inventors have completed the present invention. [Overview of the project]
