  氨基酸作为选择性酰化剂：抗疟药伯氨喹的咪唑啉丁-4-酮衍生物的区域选择性N 1-酰化

  摘要：

  使用的生物活性基于伯-咪唑烷-4-酮的酰化进行了研究Ñ α -Boc保护的甘氨酸作为酰化剂。比较了两种合成路线，八种不同的偶联方法和七种不同的溶剂。在高介电常数溶剂（例如DMF或MeCN）上基于碳二亚胺的轻度偶联提高了酰化收率，而醇类则抑制了碳二亚胺介导的酰化反应。合成目标的实现受限于咪唑烷基-4-酮环取代基R 1，R 2和R 3的大小，但诉诸于MW辅助合成可以克服此类障碍，尽管反应收率非常适中。涉及所用Boc保护的氨基酸的所有反应均具有区域选择性，而与所采用的反应条件无关。相比之下，咪唑烷丁-4-酮的区域选择性乙酰化只能通过非常温和的偶联程序来实现。

  The acylation of bioactive primaquine-based imidazolidin-4-ones was studied using Nα-Boc-protected glycine as acylating agent. Two synthesis routes, eight different coupling methods and seven distinct solvents were compared. Mild carbodiimide-based couplings on high dielectric constant solvents such as DMF or MeCN increased acylation yields, whereas alcohols inhibited carbodiimide-mediated acylations

  Peptidomimetic imidazolidin-4-one derivatives of primaquine (imidazoquines) recently displayed in vitro activity against blood schizonts of a chloroquine-resistant strain of Plasmodium falciparum. Preliminary studies with a subset of such imidazoquines showed them to both block transmission of P. berghei malaria front mouse to mosquito and be highly stable toward hydrolysis at physiological conditions. This prompted Lis to have deeper insight into the activity of imidazoquines against both Plasmodia and Pneumocystis carinii, on which primaquine is also active. Full assessment of the in vivo transmission-blocking activity of imidazoquines, in vitro tissue-schizontocidal activity on P. berghei-infected hepatocytes, and in vitro anti-P. carinii activity is now reported. All compounds were active in these biological assays, with generally lower activity than the parent drug. However, imidazoquines' stability against both oxidative deamination and proteolytic degradation suggest that they will probably have higher oral bioavailability and lower hematotoxicity than primaquine, which might translate into higher therapeutic indexes.
