Liu, Na;Wang, Yanfen;Huang, Gongchao;Ji, Conghui;Fan, Wei;Li, Haitao;Cheng, Ying;Tian, Hongqi research published 《 Design, synthesis and biological evaluation of 1H-pyrrolo[2,3-b]pyridine and 1H-pyrazolo[3,4-b]pyridine derivatives as c-Met inhibitors》, the research content is summarized as follows. Five novel 1H-pyrrolo[2,3-b]pyridine or 1H-pyrazolo[3,4-b]pyridine derivatives, with a methylene, sulfur, sulfoxide or cyclopropyl group as a linker, were designed, synthesized and biol. evaluated against c-Met and ALK. The development of these methods of compound synthesis may provide an important reference for the construction of novel 7-azaindole and 7-azaindazole derivatives with a single atom linker. The enzyme assay and cell assay in-vitro showed that 3-((2,6-dichloro-3-fluorophenyl)thio)-5-(1-(piperidin-4-yl)-1H-pyrazol-4-yl)-1H-pyrazolo[3,4-b]pyridine displayed strong c-Met kinase inhibition with IC50 of 22.8 nM, moderate ALK kinase inhibition, and strong cell inhibition with MKN-45 IC50 of 329 nM and EBC-1 IC50 of 479 nM. In order to find the better candidate compounds, 3-((2,6-dichloro-3-fluorophenyl)sulfide)-5-(1-(piperidin-4-yl)-1H-pyrazol-4-yl)-1H-pyrrolo[2,3-b]pyridine, 3-((2,6-dichloro-3-fluorophenyl)thio)-5-(1-(piperidin-4-yl)-1H-pyrazol-4-yl)-1H-pyrazolo[3,4-b]pyridine and 3-(1-(2,6-dichloro-3-fluorophenyl)cyclopropyl)-5-(1-(piperidin-4-yl)-1H-pyrazol-4-yl)1H-pyrazolo[3,4-b]pyridine were selected as tool compounds for further optimization.
