  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.

  In continuing our search of potent antimalarials based on 8-aminoquinoline structural framework, three series of novel bis(8-aminoquinolines) using convenient one to four steps synthetic procedures were synthesized. The bisquinolines were evaluated for in vitro antimalarial (Plasmodium falciparum), antileishmanial (Leishmania donovani), antimicrobial (a panel of pathogenic bacteria and fungi), cytotoxicity

  在继续研究基于 8-氨基喹啉结构框架的有效抗疟药的过程中，使用方便的一到四步合成程序合成了三个系列的新型双（8-氨基喹啉）。对双喹啉类药物的体外抗疟（恶性 疟原虫）、抗利什曼 原虫（多诺瓦尼利什曼原虫）、抗微生物剂（一组致病细菌和真菌）、细胞毒性、β-血红素抑制和高铁血红蛋白 (MetHb) 形成活性进行了评估。与母体药物伯氨喹相比，几种化合物表现出优异的抗疟活性。选择的化合物（44，61和79时在体内血液裂殖抗疟疾活性测试）（Plasmodium berghei ) 显示出有效的血液裂殖体活动。双喹啉的 MetHb 形成可以忽略不计（0.2-1.2%），这突显了它们在治疗葡萄糖-6-磷酸脱氢酶缺乏症患者中的潜力。所述双喹啉类似物（36，73和79）也表现出体外活性antileishmanial看好，和抗菌活性（43，44和76对致病细菌和真菌的面板）。这项研究的结果提供了证据，证明双（8

  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.
