A facile synthesis of unsymmetrical N,N'-diarylureas is described. The utilization of the Pd-catalyzed arylation of ureas enables the synthesis of an array of diarylureas in good to excellent yields from benzylurea via a one-pot arylation-deprotection protocol, followed by a second arylation.
Design, synthesis and biological evaluation of urea-based benzamides derivatives as HDAC inhibitors
synthesized as histone deacetylases inhibitors. Biological evaluations of these compounds included the inhibitory activity of histone deacetylases1 and cytotoxicity against different cancer cell lines in vitro. Most compounds exhibited potential histone deacetylases inhibitory activity and antitumor activities. Compound 5h behaved as potent histone deacetylases1 inhibitor (IC50 = 0.182 μM) and showed comparable
