animals. Inspired by the observation that N(5)-substituted paullones inhibit the trypanothione synthetase from the related parasite Leishmania infantum, we designed and synthesized a series of new derivatives. Although none of the new compounds displayed strong inhibition of Trypanosoma brucei trypanothione synthetase, several of them caused a remarkable growth inhibition of cultivated Trypanosoma brucei
锥虫硫醇合成酶是动素体寄生虫的必不可少的酶,它会在人类和动物中导致高度致残和致命的疾病。受到N(5)取代的paullones抑制来自相关寄生虫婴儿利什曼原虫的锥虫硫醇合成酶的观察的启发,我们设计并合成了一系列新的衍生物。尽管这些新化合物均未显示出对布鲁氏锥虫Trypanothione合成酶的强抑制作用,但其中有几种化合物对培养的布鲁氏锥虫血流形式产生了显着的生长抑制作用。最强大的同类产品3a 在鼠类巨噬细胞中显示出两位数纳摩尔浓度的抗锥虫活性和三个数量级的选择性指数。
