A series of 25 N,N′-substituted diamines were prepared by controlled reductive amination of free aliphaticdiamines with different substituted benzaldehydes. The library was screened in vitro for antiparasitic activity on the causative agents of human African trypanosomiasis, Chagas’ disease and visceral leishmaniasis. The most potent compounds were derived from a subset of diamines that contained
In order to identify novel anti-hepatitis C virus (HCV) agents we devised cell-based strategies and screened phenotypically small molecule chemical libraries with infectious HCV particles, and identified a hit compound (1) containing a hexahydropyrimidine (HHP) core. During our cell-based SAR study, we observed a conversion of HHP 1 into a linear diamine (6), which is the active component in inhibiting HCV and exhibited comparable antiviral activity to the cyclic HHP I. In addition, we engaged into the biological characterization of HHP and demonstrated that HHP does not interfere with HCV RNA replication, but with entry and release of viral particles. Here we report the results of the preliminary SAR and mechanism of action studies with HHP. (C) 2013 Elsevier Masson SAS. All rights reserved.

A series of aromatic substituted diamines was synthesized and characterized for their cytotoxic profiles against human breast and prostate tumor cell lines. Following a structure function analysis of the effects of changes of the benzyl substituents and the distance between amino groups the most potent analogues were analyzed biologically and were shown to induce apoptosis. These compounds do not induce the enzyme SSAT or deplete intracellular polyamine levels, mechanisms demonstrated by other cytotoxic polyamine analogues. (C) 2002 Elsevier Science Ltd.

The development of new chemical entities against the major diseases caused by parasites is highly desired. A library of thirty diamines analogs following a minimalist approach and supported by chemoinformatics tools have been prepared and evaluated against apicomplexan parasites. Different member of the series of N,N′-disubstituted aliphatic diamines shown in vitroactivities at submicromolar concentrations
迫切需要开发新的化学实体来对抗寄生虫引起的主要疾病。遵循极简主义方法并在化学信息学工具的支持下,已经制备了 30 个二胺类似物的文库,并针对 apicomplexan 寄生虫进行了评估。 N , N'-二取代脂肪族二胺系列的不同成员在亚微摩尔浓度下表现出体外活性,并且对弓形虫以及对氯喹敏感和耐药的恶性疟原虫菌株具有高选择性。为了证明仲胺的重要性,合成了十种N , N , N ', N'-四取代的脂肪族二胺衍生物,其活性比它们的二取代对应物低得多。进行理论研究以确定控制化合物活性的电子因素。
