  Parallel synthesis of 9-aminoacridines and their evaluation against chloroquine-resistant Plasmodium falciparum

  摘要：

  A parallel synthetic strategy to the 9-aminoacridine scaffold of the classical anti-malarial drug quinacrine (2) is presented. The method features a new route to 9-chloroacridines that utilizes triflates of salicylic acid derivatives, which are commercially available in a variety of substitution patterns. The route allows ready variation of the two diversity elements present in this class of molecules: the tricyclic aromatic heterocyclic core, and the disubstituted diamine sidechain. In this study, a library of 175 compounds was designed, although only 93 of the final products had purities acceptable for screening. Impurity was generally due to incomplete removal of 9-acridones (18), a degradation product of the 9-chloroacridine synthetic intermediates. The library was screened against two strains of Plasmodium falciparum, including a model of the drug-resistant parasite, and six novel compounds were found to have IC50 values in the low nanomolar range.

  work was to establish quantitative relationships between the biological activity of thiosemicarbazides of substituted phenylanthranyl acids and their physicochemical parameters. For that purpose, we have synthesized 18 thiosemicarbazides ( I -XVII I ) using the reaction of acylation [3] of thiosemicarbazide by chloroanhydrides of the corresponding phenylanthranyl acids [4]. The resulting thiosemicarbazides

  苯蒽酸衍生物作为抗炎、镇痛、解热药物广泛应用于实用医学，并作为寻找新的有效药物制剂的起始物质[1, 2]。然而，文献中没有报道对这些化合物的生物活性与其理化性质之间的关系进行系统研究。这项工作的目的是建立取代苯蒽基酸缩氨基硫脲的生物活性与其理化参数之间的定量关系。为此，我们使用相应苯蒽基酸的氯酸酐酰化氨基硫脲 [3] 的反应合成了 18 种氨基硫脲 (I -XVII I)。所得氨基硫脲I-XVII I表现为结晶物质，可溶于二恶烷、乙醇、苯和DMF，不溶于水。合成的化合物 I XVIII 的建议结构通过 IR 和 UV 光谱数据确认，并通过 TLC 在适当的溶剂系统中检查其纯度（表 I）。化合物 I XVIII 的 IR 光谱在 1587 1573 cmi（NH 基团的弯曲振动，酰胺 II）、16531620 cm -I（拉伸振动，酰胺 I）和 1253 1220 cml（C 的振动）区域包含吸收带=S

  Microwave irradiation was applied to a sequence of condensation reactions from readily available 9-chloroacridines to provide a range of novel acridine-isoalloxazine conjugates. The combination of these two moieties, both of biological interest, was achieved by a chromatography-free route. (C) 2014 Elsevier Ltd. All rights reserved.
