Abstract
Description
[Technical Field]
[0001] The present invention relates to a pharmaceutical composition, a 4-aminoquinazoline compound that is useful as an inhibitor of G12D mutant KRAS, and is expected to be useful, for example, as an active ingredient in a pharmaceutical composition for treating pancreatic cancer. [Background technology]
[0002] Pancreatic cancer, which is primarily pancreatic ductal adenocarcinoma, has an extremely poor prognosis, with a 5-year survival rate of less than 10% (CA Cancer J. Clin., 2016, 66, pp. 7-30), and approximately 460,000 new cases are reported annually worldwide (CA Cancer J. Clin., 2018, 68, pp. 394-424). While surgery is the most effective treatment for pancreatic cancer, early detection is difficult, leading to frequent metastasis and often ineffective surgical treatment. If surgical treatment is not an option, chemotherapy and radiation therapy are used, but these have poor survival rates. Currently, FOLFRINOX therapy (a combination therapy of 5-FU, irinotecan, and oxaliplatin with the addition of levofolinate) is the standard treatment for pancreatic cancer. However, due to its high toxicity, careful patient selection is required, such as by limiting patients to those with an ECOG performance status of 1 or less (J. Clin. Oncol., 2018, 36, pp. 2545-2556). While the epidermal growth factor receptor (EGFR) inhibitor erlotinib has been approved for use in combination with gemcitabine, its overall survival benefit is only about two weeks compared to gemcitabine alone, indicating that a satisfactory therapeutic effect has not been achieved. Therefore, there is still a need for more effective treatments (J. Clin. Oncol., 2007, 25, pp. 1960-1966).
[0003] RAS proteins are small guanosine triphosphate (GTP)-binding proteins of approximately 21 kDa, consisting of 188–189 amino acids. There are four major RAS proteins (KRAS (KRAS4A and KRAS4B), NRAS, and HRAS) produced by three genes: KRAS, NRAS, and HRAS. RAS proteins exist in an active GTP-bound form and an inactive GDP-bound form. RAS proteins are activated by the exchange of guanosine diphosphate (GDP) for GTP upon ligand stimulation of cell membrane receptors such as EGFR. Active RAS binds to 20 effector proteins, including RAF, PI3K, and RALGDS, and activates downstream signaling cascades. On the other hand, active RAS becomes inactive by converting GTP to GDP through its intrinsic GTP hydrolysis (GTPase) activity. This GTPase activity is enhanced by GTPase-activating proteins (GAPs). This indicates that RAS functions as an important "molecular switch" in intracellular signaling pathways such as EGFR, and plays an important role in processes such as cell growth, proliferation, and angiogenesis (Nature Rev. Cancer, 2011, 11, pp. 761-774; Nature Rev. Drug Discov., 2014, 13, pp. 828-851; Nature Rev. Drug Discov., 2016, 15, pp. 771-785).
[0004] When RAS mutations result in amino acid substitutions, RAS becomes constitutively active due to impaired GTPase function and reduced response to GAPs, resulting in continuous downstream signaling. This excessive signaling leads to carcinogenesis and accelerated tumor proliferation. Pancreatic ductal adenocarcinoma (PDA) is thought to develop through a process of mild to severe dysplasia (PanIN), and KRAS mutations are already present in early-stage PanIN. Subsequently, abnormalities in the tumor suppressor genes INK4A, p53, and SMAD4 occur, leading to malignant progression (Nature Rev. Cancer, 2010, 10, pp. 683-695). Furthermore, KRAS mutations are found in over 90% of PDAs, with the majority of these mutations being point mutations at codon 12 in KRAS exon 2 (Cancer Cell, 2017, 32, pp. 185-203). This indicates that KRAS plays an important role in the oncogenesis and development of pancreatic cancer.
[0005] Recently, the presence of an allosteric pocket near the switch II region of G12C mutant KRAS has been demonstrated (Nature, 2013, 503, pp. 548-551). Several compounds have been reported that irreversibly bind to G12C mutant KRAS by forming covalent bonds with the cysteine residues of G12C mutant KRAS (Cancer Discov., 2016, 6, pp. 316-329; Cell, 2018, 172, pp. 578-589; Nature, 2019, 575, pp. 217-223). Selective inhibitors of G12C mutant KRAS bind covalently to G12C mutant KRAS, inhibiting its conversion from inactive to active form and blocking downstream signaling, thereby inducing cancer cell death.
[0006] While G12C mutations in KRAS are common in non-small cell lung cancer, they occur in only a few percent of pancreatic cancers (Cancer Cell 2014, 25, pp. 272-281), and therapeutic agents for other KRAS mutations are needed. G12D mutations in KRAS are reported to be the most common KRAS mutation, occurring in approximately 34% of pancreatic cancers (Nat. Rev. Cancer, 2018, 18, pp. 767-777).

[0092] The compound of formula (I) is isolated and purified as a free compound, a salt thereof, a hydrate, a solvate, or a crystalline polymorph or an amorphous solid substance. A salt of the compound of formula (I) can also be prepared by subjecting it to a conventional salt-forming reaction.

Washing was performed three times. After washing, 10 μL of IRDye 800CW Goat anti-Rabbit IgG (LI-COR Biosciences) diluted 1:1,000 in blocking solution was added to each well as the secondary antibody and incubated at room temperature for 1 hour. The plate was centrifuged to remove the supernatant, and each well was washed three times with PBS containing 0.05% Tween-20 in the same manner as after the primary antibody reaction. After the third wash, centrifugation was performed at 171 x g for 17 seconds. After removing the supernatant, the plate was air-dried at room temperature for 3 hours or more, and the fluorescent signal at 800 nm was measured using Aerius (LI-COR Biosciences). The signal value when DMSO was added was defined as 0% inhibition, and the signal value when 1 μM trametinib was added was defined as 100% inhibition.

Cell culture was carried out under the same conditions as in Test Example 2. The next day, test compounds (six concentrations ranging from 10 μM to 3.0 nM) and DMSO, the solvent for the test compounds, were diluted 100-fold with fresh medium and added at 4 μL per well. After incubation at 37°C in the presence of 5% CO for 6 days, 20 μL of CellTiter Glo 2.0 (Promega) was added to each well. After stirring at room temperature for 1 hour using a plate mixer (FINEPCR), luminescence signals were measured using an ARVO X3 (PerkinElmer). The signal value in DMSO treatment was defined as 0% inhibition, the signal value in the absence of cells and medium alone was defined as 100% inhibition, and the 50% inhibition value (IC 50 ) was calculated by Sigmoid-Emax model nonlinear regression analysis.

[0100] Test Example 4: Evaluation of antitumor activity in mice bearing the human KRAS G12D mutation-positive pancreatic cancer line PK-1 PK-1 cells (RIKEN BRC, RCB1972) were cultured in RPMI1640 medium (Sigma-Aldrich) containing 10% fetal bovine serum (GE Life Sciences) at 37°C in the presence of 5% CO2. PK-1 cells were harvested and suspended in PBS. An equal volume of Matrigel (Becton Dickinson) was added to the suspension, resulting in a 3.0x10 7 The cell suspension, adjusted to cells / mL, was then injected into 4-5 week old male nude mice (CAnN.Cg-Foxn1 nuA 100μL volume of 100μL ... [Tumor volume (mm 3 )] = [Tumor long diameter (mm)] x [Tumor short diameter (mm)] 2 x 0.5 The tumor growth inhibition rate (%) by the test compound was calculated by defining the tumor volume of the test compound administration group on the day before the start of administration as 100% inhibition and the tumor volume of the vehicle group on the final day of administration as 0% inhibition. When the tumor volume of the test compound administration group was lower than the tumor volume on the day before the start of administration, the tumor volume on the day before the start of administration was defined as 0% regression, and a tumor volume of 0 was defined as 100% regression, and the tumor regression rate (%) of the test compound was calculated.
[0101] As a result of the above tests, it was confirmed that some compounds of formula (I) have inhibitory activity against G12D mutant KRAS and antitumor activity.
