Synthesis and antikinetoplastid activities of 3-substituted quinolinones derivatives
摘要:
A new family of quinolinone derivatives has been synthesized and evaluated for their antikinetoplastid activities against Leishmania donovani and Trypanosoma brucei brucei. Results from these structure activity relationship studies enabled identification of compounds 3a and 4g as the most active compounds against L. donovani promastigotes and amastigotes parasites (IC50 values in a range of 2-11 mu M). Additionally, compound 3b has emerged from this study as the most active compound in the series against T. b. brucei with a MEC value of 12 mu M. These three compounds are worth of further in vivo evaluation. (C) 2012 Elsevier Masson SAS. All rights reserved.
A facile and efficient Cu(I)‐catalyzedazide–alkynecycloadditionreaction for the synthesis of a series of 3‐triazolyl‐2(1H)‐quinolones 3 have been developed using 3‐azido‐quinolin‐2(1H)‐one as the coupling partner. The optimized reaction conditions involve the use of eco‐ friendly ethanol as the solvent in the presence of copper(I) thiophene‐2‐carboxylate as the catalyst, to afford good to excellent
