  8-Quinolinamines conjugated with amino acids are exhibiting potent blood-schizontocidal antimalarial activities

  摘要：

  Alanine, lysine, ornithine and valine conjugated to primaquine and other 8-quinolinamine antinialarials were prepared for blood-schizontocidal antimalarial activity evaluation. The analogues were examined in vivo against Plasmodium berghei (drug-sensitive strain) and Plasinodium yoelii nigeriensis (highly virulent multi-drug-resistant strain) infected mice models. N-1-[4-(5Butoxy-4-ethyl-6-methoxy-8-quinolylamino)pentyl]-(2S)-2,6-diaminohexanamide (20) which showed curative activity at 5 mg/kg in the P. berghei test emerged as the most effective compound. N-1-[4-(4-Ethyl-5-hexoxy-6-methoxy-8-quinolylamino)pentyl]-(2S)-2,6-diaminohexanamide (22) exhibited curative activity at 50 mg/kg against P. yoelii nigeriensis in mice and emerged as the most potent analogue against multi-drug resistant strain. The results of this study represent development of highly potent 8-quinolinamines for antimalarial drug development. (C) 2003 Elsevier Ltd. All rights reserved.

  8-Quinolinamines and Their pro prodrug conjugates as potent blood-Schizontocidal antimalarial agents

  摘要：

  Synthesis and antimalarial activities of N-8-(4-amino-1-methylbutyl)-5-alkoxy-4-ethyl-6-methoxy-8-quinolinamines (5) and their pro prodrug analogues (6-7) prepared by covalently linking 5 to the redox-sensitive (8) and esterase-sensitive (9) linkers through the amide linkage are reported. The most effective 8-quinolinamines [5c (R = C5H11) and 5f (R = C8H17)] A have exhibited in vitro and in vivo biological efficacy superior to that of the standard drug chloroquine against both drug-sensitive and drug-resistant malaria strains. Analogues 6-7 were evaluated for in vivo blood-schizontocidal activity as potential pro prodrug models for the primary amino group containing 8-quinolinamines (5). The most effective pro prodrug analogue (6c) has displayed promising activities against drug-sensitive and drug-resistant strains of Plasmodia in vivo. (C) 2003 Elsevier Ltd. All rights reserved.
