The parasitic trypanosomal species of the genera Trypanosoma and Leishmania are the causative agents of a wide variety of severely destructive diseases. One of the deadliest of these diseases is African sleeping sickness, the causative agent of which is Trypanosoma bruccei. Compounds which selectively inhibit trypanosomal glycolytic enzymes over the equivalent human glycolytic enzymes would be an excellent starting point for the design of new drugs effective in attentuating trypanosomal diseases. We propose to employ a cyclic process of three-dimensional structure determination and molecular modelling in the search for such compounds. This proposal concerns the structural determination aspect of the drug design cycle pertaining to two of these trypanosomal glycolytic enzymes, glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and aldolase.

锥虫属的寄生锥虫种类和 利什曼原虫是多种严重疾病的病原体 破坏性疾病。 这些疾病中最致命的一种是 非洲昏睡病，其病原体是锥虫 布鲁切伊。 选择性抑制锥虫糖酵解的化合物 与等效的人类糖酵解酶相比，酶将是 设计有效的新药的绝佳起点 减轻锥虫病。 我们建议采用循环 三维结构测定和分子过程 寻找此类化合物的建模。 该提案涉及 药物设计周期的结构确定方面 与其中两种锥虫糖酵解酶有关， 3-磷酸​​甘油醛脱氢酶（GAPDH）和醛缩酶。
