Description
Technical Field
The invention belongs to the field of pharmaceutical chemistry, and particularly relates to a piperidine condensed 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 signal was converted to percent inhibition using the following equation: % inhibition 100- [ (test compound signal-median minimum signal)/(median maximum signal-median minimum signal) x 100]. The maximum signal is the signal value for wells without inhibitor and the minimum signal is the signal value for wells containing a reference inhibitor sufficient to completely inhibit cell proliferation, a four-parameter non-linear regression fit curve was performed on the percent inhibition for each concentration of compound and the IC50 was calculated.
As a result: the example compounds provided herein have proliferation-inhibiting activity, IC, on NCI-H358 and MiaPaca-2 cells50Both less than 1000nM, some examples being examples 7,8,9, 11, 15, 16, etc. for NCI-H358 and MCell proliferation inhibitory Activity IC of iaPaca-250Less than 200 nM.
Test method three (ERK phosphorylation): miapaca-2 or H358 cells were seeded at a certain concentration in 96-well plates and placed at 37 ℃ in 5% CO2The next day the plate was incubated overnight with serial dilutions of test compounds (5 concentrations, 3 fold dilutions) for 24H (Miapaca-2) or 3H (H358), followed by lysis of the cells with lysis solutions containing protease and phosphatase inhibitors to extract the protein, and western blot to detect the level of p-ERK.
As a result: the example compounds provided by the invention have obvious inhibition effect on the level of phosphorylated ERK of NCI-H358 and MiaPaca-2 and IC (Integrated Circuit) as examples 7,8,9, 11, 15 and 1650Less than 500 nM.
