Synthesis, characterization and antimalarial activity of quinoline–pyrimidine hybrids
摘要:
The aim of this study was to synthesize a series of quinoline-pyrimidine hybrids and to evaluate their in vitro antimalarial activity as well as cytotoxicity. The hybrids were brought about in a two-step nucleophilic substitution process involving quinoline and pyrimidine moieties. They were screened alongside chloroquine (CQ), pyrimethamine (PM) and fixed combinations thereof against the D10 and Dd2 strains of Plasmodium falciparum. The cytotoxicity was determined against the mammalian Chinese Hamster Ovarian cell line. The compounds were all active against both strains. However, hybrid (21) featuring piperazine linker stood as the most active of all. It was found as potent as CQ and PM against the D10 strain, and possessed a moderately superior potency over CQ against the Dd2 strain (IC50: 0.157 vs 0.417 mu M, similar to threefold), and also displayed activity comparable to that of the equimolar fixed combination of CQ and PM against both strains.

A series of 33 quinolinederivatives have been synthesized and evaluated for their in vitro antibacterial activity against Mycobacterium tuberculosis H37Rv using the Alamar Blue susceptibility test and the activity expressed as the minimum inhibitory concentration (MIC) in μg/mL. Compounds 5e and 5f exhibited a significant activity at 6.25 and 3.12 μg/mL, respectively, when compared with first line
