Trypanosomacruzi and Trypanosoma brucei are the parasitic causative agents of Chagasdisease and human African trypanosomiasis (HAT), respectively. The drugs currently used to treat these diseases are not efficacious against all stages and/or parasite sub-species, often displaying side effects. Herein, we report the SAR exploration of a novel hit, 2-(4-chlorophenyl)-N-(1-propyl-1H-benzimidazol-2-yl)acetamide
The present invention relates to novel benzimidazole derivatives, their preparation, their use as pharmaceuticals and pharmaceutical compositions containing them, wherein the compounds have the formula (I):

treatment regimens. A library of 1.8 million compounds, from which the hits reported here are publicly available, was screened against Leishmania infantum as part of an optimization program; a compound was found with a 2-aminobenzimidazole functionality presenting moderate potency, low metabolic stability and high lipophilicity. Several rounds of synthesis were performed to incorporate chemical groups

The present invention concerns a fluorescence resonance energy transfer based high throughput test system to measure the formation of the HIV gp41 six-helix bundle. In a first embodiment the current invention relates to a homogeneous time resolved fluorescence-based test system comprising a first helical polypeptide consisting essentially of the sequence of IQN36 (SEQ ID NO:1); a second helical polypeptide consisting essentially of the sequence of C34 (SEQ ID NO: 2) wherein said IQN36 is labeled with a light emitting fluorophore and said C34 is labeled with an ultra-violet excitable fluorophore.
该发明涉及一种基于荧光共振能量转移的高通量测试系统,用于测量HIV gp41六螺旋束的形成。在第一实施例中,当前发明涉及一种基于均匀时间分辨荧光的测试系统,包括基本上由IQN36序列(SEQ ID NO:1)组成的第一螺旋多肽;基本上由C34序列(SEQ ID NO:2)组成的第二螺旋多肽,其中所述的IQN36标记有发光荧光团,所述的C34标记有紫外激发荧光团。
