The discovery of novel N-(2-pyrimidinylamino) benzamide derivatives as potent hedgehog signaling pathway inhibitors
摘要:
Hedgehog signaling pathway inhibitors are emerging as new therapeutic intervention against cancer. A novel series of N-(2-pyrimidinylamino) benzamide derivatives as hedgehog signaling pathway inhibitors were designed and synthesized. Most compounds presented significant inhibitory effect on hedgehog signaling pathway, among which 21 compounds exhibited more potent than vismodegib. Furthermore, compound 6a showed moderate pharmacokinetic properties in vivo, representing a promising lead compound for further exploration. (C) 2013 Elsevier Ltd. All rights reserved.

syntheses of diarylamines from a palladium-catalyzed reductive Buchwald-Hartwig amination of nitroarenes with aryl (pseudo)halides is developed. The use of upstream nitroarenes as arylamine surrogates, the judicious selection of bis(pinaco-lato)diboron (B2pin2) as a stoichiometric reducing agent, wide substrate scope including (hetero)arylhalides (Cl, Br and I) and aryl triflates, constitute the striking
