Abstract
The invention discloses a nitrogen-containing fused ring compound, a preparation method and application thereof, in particular to a nitrogen-containing fused ring compound shown as a general formula I, or pharmaceutically acceptable salt thereof, or enantiomer, diastereomer, tautomer, torsional isomer, solvate, polymorph or prodrug thereof, a preparation method and application thereof in pharmacy, wherein the definition of each group is described in the specification.
Description
Technical Field
The invention belongs to the field of pharmaceutical chemistry, and particularly relates to a nitrogen-containing fused ring compound, a compound with Ras mutein inhibition activity, a preparation method and application.
Background
RAS is the first oncogene identified in human tumors and was first found in two murine sarcoma viruses. There are three members of the RAS gene family, Hras, Kras, Nras. In human tumors, Kras mutations are most common, accounting for approximately 85%. Previous studies have shown that Kras mutations are carcinogenic because codon 12 is missense mutated, altering the structure of the Kras protein and keeping it activated at all times. Ras plays a major role in signal pathway transmission, mainly activating kinases controlling gene transcription, thereby regulating cell differentiation and proliferation, and is closely related to survival, proliferation, migration, metastasis and angiogenesis of tumor cells. According to statistics, Kras G12C mutation exists in 11% -16% of lung adenocarcinoma cases, and part of pancreatic cancer, colorectal cancer, ovarian cancer and bile duct cancer is caused by Kras mutation. However, over thirty years ago since the first discovery of Kras oncogene, the targeting drugs for EGFR, BCL and other common protooncogenes have been developed for several generations, and the targeting drugs for Kras have not been successfully developed. Historically, targeted drugs against KRas pathway mutant tumors have focused primarily on farnesyl transferase inhibitors and Raf-MEK pathway inhibitors, but with little success. In recent years, inhibitors aiming at KRas specific gene mutation are developed into hot spots, and part of inhibitors gradually go from preclinical hatching to clinical research, such as KRas G12C inhibitors AMG510, MRTX1257 and the like, and show certain curative effect in early clinical experiments. The first clinical data of the first global KRASG12C inhibitor AMG510 was finally promulgated by the american clinical oncology institute held in 6 months 2019, in which clinical studies the installed drug AMG510 was shown to prevent tumor growth in most non-small cell lung and colorectal cancer patients with KRas mutations. Therefore, finding and searching for a target drug against KRas specific mutant gene with high specificity and excellent drug availability is a major hotspot in the industry.

The following compounds of examples were prepared and synthesized in the same manner as in example 1 and example 2.
Test example 1 KrasG12C functional analysis
All enzyme and substrate solutions were prepared with reaction buffer (20mM HEPES (pH7.5), 5mM MgCl2,150mM NaCl and 0.01% tween 20). The experimental procedure was as follows: using reaction buffer configuration of 10nM GDP loaded biotinylated KRASG12C and 37.5ng/ml streptavidin europium cryptate, 384 well HiBase micro polystyrene microwell plates were loaded with 5 μ L of the above protein reaction per well, along with test sample or control compound configured with DMSO and incubated for 4 hours. Separately, 20nM GST-Raf Ras binding domain (GST-Raf RBD) and 4. mu.g/ml anti-GST XL665 antibody (Cisbio) in reaction buffer (50mM potassium fluoride and 0.05mg/ml BSA) were mixed, and after 4 hours of equilibration, 0.6. mu.M GTP. gamma.S (Sigma) and 0.08. mu.M SOS were added. Mu.l of GST-RAF RBD mixture was added to each well of the plate. Addition of this mixture at this stage initiates a nucleotide exchange reaction which facilitates conversion of the non-activated GDP-loaded KRasG12C to activated GTP γ S KRasG 12C. The specific binding between activated GTP γ S KRasG12C and GST-RAF RBD draws the distance between europium and XL665 to enhance the FRET signal, which is detected using a Pherastar (BMG) plate reader equipped with an HTRF filter module. Any compound that inhibits nucleotide exchange or inhibits the binding of activated KRAS to RAF RBD will result in a decrease in FRET signal, and the FRET dose-response data is curve-fitted using Genedata Screener and the IC50 is calculated.
Test example 2 KRASG12C mass spectrometric addition analysis
All enzyme and substrate solutions were prepared with reaction buffer (20mM HEPES (pH7.5), 5mM MgCl2,150mM NaCl and 0.01% tween 20). mu.L of GDP-loaded biotinylated KRAS G12C (4. mu.M) and 1mM test compound (final concentration: 10. mu.M) in a reaction buffer (4. mu.M) were added to each well of a 96-well polypropylene microplate, and the reaction was terminated by adding 50. mu.L of 1% formic acid after 4 hours of reaction. The plates were sealed and then read by Xevo G2 QTOF (Waters) and Acquity LC system (Waters). 10 μ L of the sample was injected into Xbridge BEH 300; c4; 3.5 μm; gradient analysis was performed for 3min on 2.1X 50mm columns (Waters). A blank sample needs to be run between each test sample. Data analysis was performed using Mass Lynx Software (Waters) using total ion number (TIC) and combining the eluted protein peak data. Apo-protein KRASG12C (Apo) and KRAS + relative compound masses (sums) were tested and the percentage of sums calculated using the following formula: sum percentage is 100x (sum of sum peak area/APO and sum peak).

NCI-H358 (lung cancer) and MiaPaca-2 (pancreatic cancer) cells (100. mu.L/well, 20000 cells/mL) were seeded in 96-well culture plates, respectively, and supplemented with 10% fetal bovine serum and 1% penicillin/streptomycin sulfate. Cells were treated with a 0.5% dimethyl sulfoxide blank, diluted with an initial 10 μ M solution of test compound diluted three times with an eight gradient, and incubated in a 5% CO2 incubator for a period of time (3-7 days). At the end of the incubation, 10. mu.L of MTT stock solution (5mg/mL) was added to each well. The plates were incubated at 37 ℃ for 4 hours and then the medium was removed. Dimethylsulfoxide (100 μ L) was added to each well, followed by sufficient shaking. The absorbance of the formazan product was measured at 570nm on a thermoscientific varioska nflash multi-mode reader. IC was obtained by fitting dose response data to a three parameter nonlinear regression model using graphpadprism6.0 software50The value is obtained.
