Fibroblast growth factor receptor (FGFR) is a promising therapeutic target for cancer treatment. A series of 5-aminopyrazole and 5-amino-1,2,3-triazole derivatives were designed as FGFR inhibitors based on the docking mode of Debio1347 within the FGFR kinase domain. The inhibitory effects on FGFR2 kinase and the antitumor activities against human gastric cancer SNU16 cell lines were evaluated. Furthermore, the preliminary structure-activity relationships (SAR) was discussed. The results demonstrated that several compounds present good potency against FGFR2 kinase. 1-(5-Amino-1-(2-methyl-1H-benzo[d]imidazol-6-yl)-1H-pyrazol-4-yl)-1-(1H-thieno[3,2-b]pyrrol-2-yl)methanone (8) and 1-(5-amino-1-(2-methyl-1H-benzo[d]imidazol-6-yl)-1H-1,2,3-triazol-4-yl)-1-(1H-indol-2-yl)methanone (18) were the most potent with IC50 values of 3.3 and 2.3 nmol·L1, respectively, which are similar to that of Debio1347. Compounds 8 and 18 exhibited slightly weaker antitumor activity against SNU16 cell lines than Debio1347 with IC50 value of 77.3, 155.2 nmol·L1, respectively.
