[0002] The present disclosure claims priority to Chinese patent application No. 202410174951.4, filed with the Patent Office of China on February 7, 2024, entitled “A six-membered lactam compound and its application”, and Chinese patent application No. 202411185907.X, filed with the Patent Office of China on August 27, 2024, entitled “A six-membered lactam compound and its application”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates to the technical field of drug synthesis, and in particular to a six-membered lactam compound and applications thereof. Background Art

[0004] MEK is a member of the mitogen-activated protein kinase kinase family and participates in the Ras / Raf / MEK / ERK pathway (the classic MAPK signaling pathway), mediating physiological processes such as cell proliferation, survival, differentiation, migration, and apoptosis. MEK inhibitors (PD0325901, CH4987655, trametinib, cobimetinib, selumetinib, etc.) have shown clinical efficacy in cancers with RAF mutations (such as malignant melanoma with BRAF mutations) as a single agent or in combination with RAF inhibitors. Although several MEK inhibitors have been approved by regulators, these MEK inhibitors have not yet achieved the expected clinical efficacy. In many tumors carrying RAS or RAF mutations, abnormal activation often occurs when BRAF or MEK inhibitors are used alone. Therefore, existing MEK inhibitors generally have the problem of insufficient activity and incomplete inhibition.

[0066] Those skilled in the art will appreciate that, since nitrogen requires an available lone pair of electrons to be oxidized to oxides, not all nitrogen-containing heterocycles are capable of forming nitrogen oxides. Those skilled in the art will recognize nitrogen-containing heterocycles that are capable of forming nitrogen oxides. Those skilled in the art will also recognize that tertiary amines are capable of forming nitrogen oxides. Synthetic methods for preparing nitrogen oxides of heterocycles and tertiary amines are well known to those skilled in the art and include oxidizing heterocycles and tertiary amines with peroxyacids such as Peracetic Acid and Metachloroperbenzoic Acid (mCPBA), hydrogen peroxide, alkyl hydroperoxides such as tert-butyl hydroperoxide, sodium perborate, and dioxirane such as dimethyldioxirane. These methods for preparing nitrogen oxides have been extensively described and reviewed in the literature, see for example: TL Gilchrist, Comprehensive Organic Synthesis, vol. 7, pp 748-750 (AR Katritzky and AJ Boulton, Eds., Academic Press); and GWH Cheeseman and ESGWerstiuk, Advances in Heterocyclic Chemistry, vol. 22, pp 390-392 (AR Katritzky and AJ Boulton, Eds., Academic Press).

[0433] Biological activity test

[0434] 1. Inhibitory activity of compounds against HCT116

[0435] Human colorectal cancer cell line HCT116 was cultured in the corresponding culture medium containing 10% fetal bovine serum (FBS, Yeast, China) and penicillin / streptomycin (Thermo, USA) in an incubator with 5% CO2 and a temperature of 37°C. The cytotoxicity of the target compounds against HCT116 cells was investigated using CCK-8 (Meilune, CHN). Approximately 3,000 cells were seeded per well of a 96-well plate. After cell attachment, 200 μL of fresh culture medium containing various concentrations of the compounds was added. After incubation for 72 hours, 10 μL of CCK-8 was added to each well and incubated for an additional 2 hours. The plate was shaken for approximately 20 seconds, and the absorbance was measured at a wavelength of 450 nm using a microplate reader. Reference compounds binimetinib and avutometinib were purchased from Shanghai MedChemExpress. The experimental results are shown in Table 2.

[0436] Table 2 Test results of the inhibitory activity of compounds on HCT116 cells

[0437] Conclusion: The disclosed compounds significantly inhibit the anti-proliferative activity of HCT116 cells, and the anti-tumor activity of the preferred compounds is significantly better than that of the MEK1 / 2 inhibitor binimetinib and the MEK / RAF dual inhibitor avutometinib.

[0438] 2. Immunoblotting of Compound W2

[0439] Protein samples were extracted using RIPA lysis buffer (biosharp, China). Cellular proteins were separated by 10% SDS-PAGE and transferred to polyvinylidene difluoride membranes (Millipore, IRL). The membranes were blocked with 5% skim milk powder dissolved in PBST. The membranes were incubated overnight at 4°C with the following primary antibodies: rabbit monoclonal antibody against MEK1 / 2 (D1A5) (CST, USA), rabbit monoclonal antibody against phospho-MEK1 (S217 / 221) (41G9) (CST, USA), rabbit monoclonal antibody against ERK1 / 2 (ZENBIO, China), rabbit monoclonal antibody against phospho-Erk1 (T202 / Y204) and Erk2 (T185 / Y187) (Abways, China), GAPDH (Abways, China), and β-actin (Abways, China). Compound VS-6766 was purchased from MedChemExpress, Shanghai. The membrane was washed four times with PBST and then incubated with a horseradish peroxidase-conjugated secondary antibody (diluted in 5% milk) for 45 minutes. Specific bands were detected using SuperKine™ West Femto Highest Sensitivity Substrate (Abbkine, USA), and images were taken using a ChemiScope 6100 (Clinx, China).
