Abstract
The application discloses a pyrrole [2,3-b ] pyridine derivative represented by a formula (I) or an isotopically-labeled compound thereof, or an optical isomer, a geometric isomer, a tautomer or an isomer mixture thereof, or a pharmaceutically acceptable salt thereof, or a prodrug thereof, or a metabolite thereof, a preparation method thereof and application of the pyrrole [2,3-b ] pyridine derivative serving as a RET kinase inhibitor, and a pharmaceutical composition containing the derivative. Experiments have shown that the compounds according to the application are better able to inhibit the activity of RET and its mutants compared to the prior art drugs.
Description
Technical Field
The application belongs to the field of medicines, and in particular relates to application of a pyrrole [2,3-b ] pyridine derivative or an isotopically-labeled compound thereof, or an optical isomer, a geometric isomer, a tautomer or an isomer mixture thereof, or pharmaceutically acceptable salt or prodrug thereof, or a metabolite thereof, a preparation method thereof and an application of the derivative serving as a RET kinase inhibitor, and a pharmaceutical composition containing the derivative.
Background
With the deep research of RET gene mutation, RET is becoming a target point for accurate treatment of various tumors. At present, small molecule inhibitors targeting RET are mainly divided into: non-specific multi-target inhibitors and specific RET inhibitors.
RET-related multi-target kinase inhibitors are successively developed and approved for marketing, such as Vandetanib (Vandetanib), cabatinib (Carbozantinib) and sunitinib (Sunitinib), but the targeting of the whole RET gene fusion mutation is not strong and the effectiveness is poor; subsequently, tenib drugs such as lenvatinib (Lenvatinib), ai Leti, argatrafinib (Agerafenib), motsemib (Motesanib), dortetinib (Dovitinib), plaitinib (Ponatinib) and the like have also been used to treat patients with RET gene fusion mutant NSCLC; besides RET activity, most of the RET nonspecific multi-target inhibitors inhibit platelet-derived growth factor receptor (platelet-derived growth factor receptors, PDGFR) and vascular endothelial growth factor receptor (vascular endothelial growth factor receptor, VEGFR) simultaneously, so that toxic and side effects are caused in clinical treatment, the response rate of the RET nonspecific multi-target inhibitors is generally less than 50%, and side effects such as hypertension are caused by simultaneously inhibiting VEGFR, most of the RET nonspecific multi-target inhibitors cannot penetrate through the blood brain barrier, and the RET nonspecific multi-target inhibitors have low applicability to patients with advanced brain metastasis of cancers and further limit the use of the patients.
The two new drugs of high-activity high-selectivity RET inhibitor Seapatinib (Selpercatinib, LOXO-292) and common Lei Xiti Ni (Pralsetinib, BLU-667) belong to first-generation selective RET small molecule inhibitors, have higher selectivity specificity than other multi-target inhibitors, have a certain inhibition effect on VEGFR-2, have tolerance, and clinically observe that with increasing dosage, the central nervous system symptoms related to cancer are relieved to a certain extent, and partial relief is realized on the basis of brain metastasis. LOXO-292 and BLU-667 have good therapeutic effects on RET and lower off-target toxicity.
Resistance develops with these two first generation RET inhibitors. Compared with EGFR, ALK and other targets, RET is not provided with a drug aiming at drug-resistant mutation.
It has been reported that RET kinase signal transduction plays an important role in various human cancers, and in which RET's gatekeeper residue RET V804 and solvent front residue G810 mutation in kinase ATP binding site are the main causes of lowering of ATP binding site by Seapatinib (Selpercatinib) and Pr Lei Xiti Ni (Pralsetinib), resulting in the occurrence of drug resistance, leading to the occurrence and progress of cancer, there is an urgent need to develop inhibitors effective for RET mutation, particularly solvent front mutation. The application aims to overcome the drug resistance mutation and develop a next generation RET inhibitor.

When the saturation of the cells is 80% -90% and the number reaches the requirement, the cells are collected, counted and inoculated. Animals: balb/c nude mice (athymic nude mice), females, 6-8 weeks old, weighing 18-22 grams, were offered by Jiangsu Jiuzhikang Biotechnology Co., ltd or Beijing Vitolith laboratory animal technology Co., ltd. Tumor inoculation: 0.2 ml (1X 106) Ba/F3 KIF5B-RET-G810R cells (matrigel added, volume ratio 1:1) were inoculated subcutaneously on the right back of each mouse and the group administration was started when the tumor average volume reached about 100-120 mm 3 (as close to 100 mm 3 as possible). Animal experiment grouping and dosing regimen: cell lines: ba/F3 KIF5B-RET-G810R, 6 animals in each group, vehicle group, positive control group and administration group; the dosage is 10 mg/kg or 25 mg/kg, the volume parameter is 10 μl/g, the administration route is gastric lavage, and the administration frequency is BID. Animal feeding: after animals arrive, the experiment can be started after 3-7 days of isolated quarantine feeding in the experimental environment. Animals were kept in SPF-class animal houses with independent air supply cages, no more than 5 animals per cage. Grouping animals: subcutaneous tumor states were observed daily after inoculation was completed, animals were weighed before grouping, tumor volumes were measured, and random groupings were made according to data. Tumor volume was measured by vernier calipers, with the formula tv=0.5 a ×b2, where a is the long diameter of the tumor and b is the short diameter of the tumor. The tumor-inhibiting effect of the compound was evaluated by TGI (%) or relative tumor proliferation rate T/C (%). TGI (%) reflects the tumor growth inhibition rate. Calculation of TGI (%): TGI (%) = [ (1- (mean tumor volume at the end of the treatment group administration-mean tumor volume at the beginning of the treatment group administration))/(mean tumor volume at the end of the treatment with solvent control group-mean tumor volume at the beginning of the treatment with solvent control group) ]x100%.
