Sugar derivatives mimicking compounds which take part in the catalysed reaction have been assayed as alternative substrates and/or competitive inhibitors of 6-phosphogluconate dehydrogenase from Trypanosoma brucei and sheep liver. Phosphonate analogues have been synthesised and the new compound 5-deoxy-5-phosphono-D-arabinonate shows good selectivity towards the parasite enzyme. A number of 4-carbon
已经测试了模仿参与催化反应的化合物的糖衍生物作为来自布鲁氏锥虫和绵羊肝的6-磷酸葡萄糖酸酯脱氢酶的替代底物和/或竞争性抑制剂。已合成了膦酸酯类似物,新的化合物5-deoxy-5-phosphono-D-arabinonate对寄生虫酶表现出良好的选择性。许多4碳和5碳链烷醛酸是寄生虫酶的强抑制剂,其K(i)值低于底物K(m),某些酰基衍生物也是有效的抑制剂。对寄生虫酶具有显着选择性的化合物中,至少有五种代表针对这一最近验证的靶标的锥虫病药物的线索。
