Novel co-aminoacyl and -alkyl derivatives of 7-chloroquinolin-4-amine were prepared and their structures confirmed by NMR spectroscopy. Their antiprotozoal activities were examined in vitro against the sensitive NF54 strain as well as against the multiresistant K-1 strain of Plasmodium falciparum and against Trypanosoma brucei rhodesiense (STIB 900). The results were compared with the activities of clinically used drugs. Their antitypanosomal activities were only moderate whereas their antiplasmodial activities looked very promising. Some were equal or slightly more active than chloroquine against the sensitive strain. However, in comparison to chloroquine, the activity of the new compounds was decreased much less in the resistant strain. Several possessed activity against both strains in low nanomolar concentration. (C) 2016 Elsevier Ltd. All rights reserved.

visualized as valuable tool in cancer management. In the current study, the synthesis of novel 1‐4‐(7‐chloroquinolin‐4‐yl)piperazin‐1‐yl)‐2‐(N‐substituted‐amino)‐ethanone derivatives (4a–t) was achieved through the amination of 2‐chloro‐1‐(4‐(7‐chloroquinolin‐4‐yl)piperazin‐1‐yl)ethanone (3) with different secondary amines. The structures of the target compounds were confirmed by IR, 1H‐NMR, 13C‐NMR
