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
Design, synthesis and biological evaluation of novel acridine and quinoline derivatives as tubulin polymerization inhibitors with anticancer activities
A series of acridine and quinoline derivatives were designed and synthesized based on our previous work as noveltubulin inhibitors targeting the colchicine binding site. Among them, compound 3b exhibited the highest antiproliferativeactivity with an IC50 of 261 nM against HepG-2 cells (the most sensitive cell line). In addition, compound 3b was able to suppress the formation of HepG-2 colonies. Mechanism
