Nitrogen-Containing Heterocyclic Compound, Preparation Method Therefor and Use Thereof

TECHNICAL FIELD

The present disclosure relates to a nitrogen-containing heterocyclic compound, a preparation method therefor and use thereof.

BACKGROUND

Ras (Rat sarcoma viral oncogene) was first found in rat sarcoma. There are three members in the ras gene family of mammals, namely H-ras (HRAS), K-ras (KRAS) and N-ras (NRAS), where the fourth exon of K-ras has variants A and B. Ras gene is widely found in various eukaryotes such as mammals, fruit flies, fungi, nematodes and yeasts, and is expressed at various levels in different tissues, where H-Ras is mainly expressed in skin and skeletal muscle, K-Ras is mainly expressed in colon and thymus, and N-Ras is expressed at a high level in testis. Ras protein regulates and controls signal transduction by switching the binding to GTP/GDP as a molecular switch in cell signal transduction, thereby regulating the life processes such as proliferation, differentiation, senescence and apoptosis of cells.

The mutant RAS are closely associated with the occurrence and development of human tumors, and are present in about 30% of human tumors. KRAS mutation is most common and accounts for approximately 85% of cases, and NRAS and HRAS account for 12% and 3%, respectively. KRAS mutation is mainly found in pancreatic, colorectal and lung cancers, NRAS mutation is common in melanoma and acute myelogenous leukemia, and HRAS mutation is common in bladder and head and neck cancers. Ras proto-oncogene mutation occurs mainly by point mutation. More than 150 different Ras point mutations have been found, with mutations in the glycine at positions 12 and 13 and glutamine at position 61 being the most common.

For decades, efforts have been made to develop small molecule inhibitors targeting Ras. Scientists have been hoping to develop competitive inhibitors of GTP that act directly on the Ras protein. However, this has not been successful because of the strong affinity between GTP and Ras (pmol/L level), the high concentration of GTP in cells (0.5 mM), the lack of a pocket in the RAS protein structure that facilitates the binding of small molecules, and the like. In recent years, some advances have been made in drug development using the allosteric site of K-Ras G12C mutant. In 2013, a team of researchers reported the discovery about K-Ras G12C small molecule inhibitors (Nature, 2013, 503, 548-551). They identified a novel binding pocket located below the molecular switch II region from K-Ras G12C mutant. Those inhibitors bind to the allosteric pocket and covalently bind to nearby Cys12, thereby selectively inhibiting the activation of K-Ras G12C. Other researchers have reported KRAS inhibitors with cellular activity (Science, 2016, 351, 604-608). Compound AMG510 from Amgen, studied in a clinical trial began in 2018, is the first small molecule inhibitor directly targeting KRAS to enter clinical studies, and has received accelerated marketing approval from the U.S. FDA in May 2021.

In conclusion, after decades of unremitting efforts, the understanding of Ras has been gradually improved, but only drugs for KRAS G12C mutation have been marketed so far, and there is no particularly effective treatment for other different mutations. The search for compounds with better inhibitory effects on Ras remains a hot and difficult research area in new drug development.

Trimethyloxonium tetrafluoroborate (2.40 g, 16.30 mmol) was added at room temperature and the mixture was stirred for 2 hours under nitrogen atmosphere. The reaction was quenched by addition of saturated aqueous sodium bicarbonate (150 mL). Dichloromethane (150 mL×2) was added for extraction, and the organic phase was washed with brine (100 mL×2), and purified by column chromatography (mobile phase: ethyl acetate/petroleum ether=1/5) to obtain compound I-1-f (2.10 g, 46%). LC-MS (ESI): m/z 312.1 (M+H)⁺.

Synthesis of Compound I-1-e

Compound I-1-f (2.10 g, 6.75 mmol) was dissolved in ethyl acetate (50 mL) and 85% pure m-CPBA (3.42 g, 16.88 mmol) was added at room temperature. After the mixture was stirred at 0° C. for 3 hours, saturated sodium bicarbonate solution (180 mL) was added to quench the reaction. Ethyl acetate (500 mL×2) was added for extraction, and the organic phase was concentrated and purified by column chromatography (mobile phase: ethyl acetate/petroleum ether=1/3) to obtain compound I-1-e (2.10 g, 91%). LC-MS (ESI): m/z 328.1 (M+H)⁺, m/z 343.1 (M+H)⁺.

Effect Example 1 Proliferation Inhibition of Compounds on RAS Cell Lines Measured by CTG

NCI-H358 is a human non-small cell lung cancer cell line with KRAS G12C mutation; AGS is a gastric cancer cell line with KRAS G12D mutation; SW480 is a colon cancer cell lines with KRAS G12V mutation; A375 is a wild type malignant melanoma cell line. The proliferation inhibitory effect of the compounds on various mutations was evaluated by determining the proliferation inhibitory activity of the compounds on these cell lines.

The assay was conducted on either 384-well plates or 96-well plates. The procedures are as follows:

The cell suspensions were added to 384- or 96-well plates (384-well plate: 40 μL; 96-well plate: 100 μL) except for peripheral wells. The plates were incubated in a carbon dioxide incubator overnight. Prepared compounds (10 concentration gradients by serial 3-fold dilution) were added to the wells. The cell plates were incubated in a carbon dioxide incubator for 120 hours. CellTiter Glo reagent (384 well plate: 25 μL; 96 well plate: 100 μL) was added to the 384- or 96-well plates. The plates were shaken for 10 minutes away from light, and incubated for 10 minutes. The plates were read by EnVision system. Inhibition curves were plotted using XLFit and IC₅₀values were calculated. The activity results for representative compounds are shown in Tables 1 below. “IC₅₀>10 μM” is denoted by “*”, “10 μM≥IC₅₀>1 μM” is denoted by “*”, “IC₅₀≤1 μM” is denoted by “***”, “---” means no data.
