Description
The technical field is as follows:
the invention relates to an acetylenic heterocyclic compound or a pharmaceutically acceptable salt thereof as an FGFR inhibitor; a pharmaceutical composition containing the alkynylated heterocyclic compound or a pharmaceutically acceptable salt thereof; a process for producing the alkynylated heterocyclic compound or a pharmaceutically acceptable salt thereof; the application of the alkynylated heterocyclic compound or pharmaceutically acceptable salt thereof or a pharmaceutical composition containing the alkynylated heterocyclic compound or pharmaceutically acceptable salt thereof in preparing medicaments for treating and/or preventing FGFR related diseases, particularly tumors.
Background art:
fibroblast Growth Factor Receptors (FGFR) are Receptor Tyrosine Kinases (RTK), and the FGFR family mainly comprises four subtypes of FGFR1-, FGFR2, FGFR3 and FGFR 4. FGFR1 is a transmembrane protein belonging to the receptor tyrosine kinase, consisting of three major components: namely an extracellular domain, a transmembrane domain and a cell domain, the extracellular domain is a binding domain of the ligand Fibroblast Growth Factors (FGFs). FGFs are also a polygenic family, and there are 19 members, namely FGF1 also known as acidic fibroblast growth factor (aFGF), FGF2 also known as basic fibroblast growth-related document factor (basic FGF, bFGF), which have biological activities of stimulating the growth of fibroblasts, vascular endothelial cells, smooth muscle cells and nerve cells, and FGFR1, which is a high affinity receptor. After FGF is combined with an extracellular segment of FGFR1, a tyrosine kinase active region of an inner segment of a receptor cell firstly generates autophosphorylation, then receptor target protein generates transphosphorylation, and a signal of a ligand is transmitted to a cell nucleus through a family structure and family relation of a protein cascade reaction, so that the effects of promoting damage repair, embryonic development and skeleton formation are achieved.
However, when FGFR is mutated or overexpressed, it causes excessive activation of the FGFR signaling pathway and further induces normal cell carcinogenesis. Wherein, over-activation of RAS-RAF-MAPK stimulates cell proliferation and differentiation; over-activation of PI3K-AKT results in inhibition of apoptosis; SATA is closely related to promoting tumor invasion and metastasis and enhancing tumor immune escape capacity; the PLC gamma signal channel is an important way for regulating and controlling the metastasis of tumor cells. Next Generation Sequencing (NGS) on 4853 solid tumor types showed, according to a study published in Clinical Cancer Research in 2015, FGFR aberrations (abortions) and abnormal activation were found in approximately 7.1% of cancers, mostly gene amplification (66%), followed by mutations (26%) and rearrangements (8%). FGFR distortion exists in almost all detected malignant tumors, and the cancers with high incidence rate include urothelial carcinoma, cholangiocarcinoma, breast cancer, endometrial carcinoma, squamous epithelial carcinoma and the like; meanwhile, the abnormal activation of FGFR is also found in tumors such as lung cancer, liver cancer, breast cancer and the like.
There are currently some non-FGFR specific drugs on the market, such as Sunitinib from pfizer, lentitini from Eisai, and nintedanib from Boehringer ingelheimer. Whereas the only FGFR inhibitors approved by the FDA to be marketed are balversa (erdafitinib) and pemazyre (pemigatinib). Small molecule inhibitors of FGFR1/2/3 entering the clinic are: infigrtinib (BGJ398) and AZD4547, fisogatinib (BLU-554), Roblitiniib (FGF401), H3B6527, lucitanib (E-3810), Futibatinib (TAS-120), RPN1371, ICP-192, derazatinib, 3D185, BPI-17509, HMPL-453.
Although the development of FGFR inhibitors has attracted the deployment of numerous companies both at home and abroad, and although 2 FGFR inhibitors are already on the market, there is still a need to develop new compounds due to the prospects they show in the treatment of various malignancies. Through continuous efforts, the invention designs an irreversible inhibitor which has proprietary intellectual property rights and shows excellent activity on FGFR-1-4 protein kinase.

Example 31: in vitro activity inhibition assay for kinases FGFR1, FGFR2, FGFR3 and FGFR4
FGFR1, FGFR2, FGFR3 and FGFR4 protein kinase activities were determined by using a Caliper mobility shift assay (Caliper mobility shift assay). Compounds were dissolved in DMSO and diluted with kinase buffer, and 5 μ L of compound (10% DMS0) at 5-fold final reaction concentration was added to the 384-well plate. After adding 10. mu.L of a 2.5-fold enzyme solution (FGFR 1, FGFR2, FGFR3 and FGFR4, respectively), the mixture was incubated at room temperature for 10 minutes, and then 10. mu.L of a 2.5-fold substrate (FAM-labeled peptide and dATP) solution was added.

Conversion data were read on a Caliper EZ Reader II (Caliper Life Sciences). The conversion was converted to inhibition data (% inhibition ═ max-sample conversion)/(max-min) × 100). Where max refers to DMSO control transferConversion rate, min, refers to the conversion rate of the enzyme-inactive control. The concentration and the inhibition rate of the compound are used as horizontal and vertical coordinates to draw a curve, XLFit excel add-in version4.3.1 software is used for fitting the curve and calculating IC50.

Example 32: human hepatoma cell Hep3B survival assay
The human liver cancer Hep3B cell line is derived from ATCC. The cells were cultured in DMEM liquid medium, and fetal bovine serum (10% FBS) and penicillin-streptomycin (100,000U/L) were additionally added. The cells were maintained in culture at 37 ℃, 95% humidity and 5% carbon dioxide. For the experiments Hep3B cells were plated at a density of 3000 cells per well in 96-well plates at a cell suspension volume of 100PL per well and cells were cultured overnight to allow cell attachment. The following day, each compound was diluted in DMSO in a three-fold gradient, and a 1PL compound DMSO solution was added to the cell culture medium, with IM DMSO as a control, with three parallel side wells for each compound concentration. Cells were then placed in a 37 ℃ incubator and after 72 consecutive hours of compound treatment, 50 μ L of CellTiter-Glo (Promega, Madison Wis.) was added to the cell culture medium and the Relative Luminescence Units (RLU) of each well were determined and cell viability and compound activity (IC) were calculated50) Wherein "A" represents IC50Less than or equal to 10 nM; "B" means 10<IC50Less than or equal to 100 nM; "C" means 100<IC50Less than or equal to 500 nM; 'D' tableDisplay 500<IC50Less than or equal to 2000 nM.
