N 1-{4-[(10S)-Dihydroartemisinin-10-oxyl]}phenylmethylene-N 2-(2-methylquinoline-4-yl)hydrazine derivatives as antiplasmodial falcipain-2 inhibitors
摘要:
A series of N (1)-{4-[(10S)-dihydroartemisinin-10-oxyl]}phenylmethylene-N (2)-(2-methylquinoline-4-yl) hydrazine derivatives 9a-9n possessing 4-quinolylhydrazone and artemisinin cores were herein synthesized and evaluated for their activities against cysteine protease falcipain-2 of Plasmodium falciparum. The structures were clearly confirmed by elemental analysis, H-1 NMR, and mass spectra. The pharmacological results indicated that all compounds showed excellent activity against recombinant falcipain-2 (IC50 = 0.15-2.28 mu M). The best one of this series was compound 9d (IC50 = 0.15 mu M). The molecular docking results showed that the compound 9d made close contact with the key active site of cysteine protease falcipain-2.
