from a neural network model published by our group. The synthesis and evaluation of this new class of trypanocidal agents are described. These compounds inhibit the growth of Trypanosoma cruzi, comparable with benznidazole or nifurtimox. In vitro assays were performed to study their effects on the growth of the epimastigote form of the Tulahuen 2 strain, as well as the epimastigote and amastigote forms
从我们小组发表的神经网络模型中鉴定出了具有抗增殖克氏锥虫特性的咪唑并[4,5- c ] [1,2,6]噻二嗪2,2-二氧化物新家族。描述了这种新型的杀锥虫剂的合成和评估。这些化合物抑制了克氏锥虫的生长,与苯硝唑或硝呋替莫相当。进行了体外测定,以研究它们对图拉胡恩2株的前鞭毛体形式,以及克氏锥虫CL克隆B5的前鞭毛体和鞭毛体形式的生长的影响。。为了验证对寄生虫细胞的选择性,在哺乳动物细胞(即J774鼠巨噬细胞和NCTC克隆929成纤维细胞)中研究了最相关化合物的非特异性细胞毒性。此外,测定了这些化合物对Cruzipain的抑制作用。体内研究表明,其中一种化合物19显示出有趣的锥虫杀虫活性,并且可能是治疗查加斯病的极有希望的候选者。
