Discovery of 8-(6-Methoxypyridin-3-yl)-1-(4-(piperazin-1-yl)-3-(trifluoromethyl)phenyl)-1,5-dihydro-4H-[1,2,3]triazolo[4,5-c]quinolin-4-one (CQ211) as a Highly Potent and Selective RIOK2 Inhibitor
摘要:
in both enzymatic and cellularstudies. It also exhibits potent proliferation inhibition activity against multiple cancer cell lines and demonstrates promising in vivo efficacy in mouse xenograft models. The crystal structure of RIOK2-CQ211 sheds light on the molecular mechanism of inhibition and informs the subsequent optimization. The study provides a cell-active chemicalprobe for verifying RIOK2
A CuAAC/Ullmann C–C Coupling Tandem Reaction: Copper-Catalyzed Reactions of Organic Azides with N-(2-Iodoaryl)propiolamides or 2-Iodo-N-(prop-2-ynyl)benzenamines
摘要:
A novel copper-catalyzed tandem reaction was developed by utilizing two famous copper-catalyzed reactions, CuAAC and Ullmann coupling. The trapping of the C-Cu intermediate produced in CuAAC led to further formation of an aryl C-C bond through intramolecular Ullmann C-C coupling.
