  Antimalarials. 14. 5-(Aryloxy)-4-methylprimaquine analogs. A highly effective series of blood and tissue schizonticidal agents

  摘要：

  A series of five 5-(aryloxy)-4-methylprimaquine analogues has been prepared and evaluated for antimalarial activity. The compounds were tested for suppressive activity against Plasmodium berghei in mice and for radical curative activity against Plasmodium cynomolgi in the rhesus monkey. The compounds were not only significantly superior to primaquine as radical curative agents but also were suprisingly highly effective as suppressive agents.

  本类化合物包括4-甲基-5-（未取代和取代的苯氧基）-6-甲氧基-8-（氨基烷基氨基）喹啉作为游离碱和药学上可接受的酸胺盐。这些化合物是高效的抗疟药物，令人惊讶的是，它们既具有组织无性红体杀灭（根治）作用，又具有血液无性红体杀灭（抑制）作用。此外，这些药物的治疗指数显著优于目前组织无性红体杀灭药物首选的前奎宁。在可耐受的剂量水平下，前奎宁没有有用的血液无性红体杀灭作用。

  Compounds of the class including 4-methyl-5-(unsubstituted and substituted phenoxy)-2,6-dimethoxy-8-(aminoalkylamino)quinolines as the free bases and pharmaceutically acceptable acid amine salts are described. The compounds are highly effective antimalarial agents which possess both tissue schizonticidal (radical curative) and blood schizonticidal (suppressive) acitivity. In addition, these drugs have significantly better therapeutic indices than primaquine which is the current tissue schizonticidal drug of choice. Primaquine possesses no useful blood schizonticidal activity at tolerated dose levels. The new 2-methoxy substituted compounds produce markedly less methemoglobin at effective dose levels and thus permit a higher degree of safety than analogs which are unsubstituted in the 2-position.

  本类化合物包括4-甲基-5-（未取代和取代的苯氧基）-2,6-二甲氧基-8-（氨基烷基氨基）喹啉作为自由碱和药学上可接受的酸胺盐。这些化合物是高效的抗疟疾药物，具有组织无性繁殖体杀灭（根治）和血液无性繁殖体杀灭（抑制）活性。此外，这些药物的治疗指数显著优于目前选择的组织无性繁殖体杀灭药物-盐酸伯氨喹。在可耐受的剂量水平下，盐酸伯氨喹没有有用的血液无性繁殖体杀灭活性。新的2-甲氧基取代化合物在有效剂量水平下产生的甲血红蛋白明显较少，因此比2-位未取代的类似物具有更高的安全性。

  Improved means for the chemotherapy of malaria have been achieved with 5-oxy-primaquine analogues having the formula: ##STR1## wherein R.sub.4 represents hydrogen or a methyl grouping, and R represents an alkyl group containing 3 to 12 carbon atoms and pharmaceutically acceptable salts thereof, wherein the salt-forming acid may be organic or inorganic in nature. These primaquine-related compounds afford improvement in the chemotherapy of malaria by exerting plasmodicidal action on malaria parasites which may be present in either the blood, formed tissues, or blood and formed tissues of the mammalian host. Such broad and practical spectrum of effectiveness distinguishes the said primaquine analogues, which may be administered parenterally or perorally to infected animals.

  已经通过具有以下式子的5-氧基-前胡碱类似物实现了改进的疟疾化疗方法：##STR1## 其中R.sub.4代表氢或甲基基团，R代表含有3至12个碳原子的烷基基团及其药物可接受的盐，其中形成盐的酸可以是有机或无机的。这些前胡碱相关化合物通过对哺乳动物寄主的血液、形成组织或血液和形成组织中可能存在的疟原虫发挥疟原虫杀灭作用，从而改善了疟疾的化疗效果。这种广泛而实用的效果谱区别于所述的前胡碱类似物，可以通过注射或口服给感染的动物。

  专利倾向于定义由马库什结构的组合性质描述的巨大化学空间。然而，新主要活性成分的优化通常是由简单的 Free Wilson 方法驱动的。这一过程导致对命中化合物附近的化学空间进行高度集中的研究，留下许多可能存在高度生物活性储层的未探索区域。这项研究旨在证明，这种公开的化学空间可以隐藏具有值得研究的有趣潜在生物活性的化合物。这强调了拓宽传统策略之外的方法的价值和必要性。因此，我们主张采用一种在早期药物发现阶段可能更有效的替代方法。我们选择2018年FDA批准的单剂量根治疟疾药物他非诺喹的案例来说明这一过程。通过对他非诺喹化学空间的深入探索，合理鉴定并合成了七种具有潜在抗疟活性的化合物。这一小组代表了迄今为止报道的 58 种类似物尚未探索的化学多样性。经过生物学评估，结果证明我们的合理设计方法已被证明是一种非常有效的探索性方法，适合早期药物发现阶段。
