previously reported inhibitors. The most active compound reported here against the P. falciparum enzyme had a K(i) of 0.2 microM. Molecular modeling studies provided a good rationale for the observed activities. Preliminary ADME studies indicated that some of the lead compounds are drug-like molecules. These compounds are useful tools for further investigating P. falciparum dUTPase for the development
我们报告发现新型的基于尿嘧啶的无环化合物作为脱氧尿苷5'-三磷酸核苷酸水解酶(dUTPase)抑制剂的发现,脱氧尿苷5'-三磷酸核苷酸水解酶(dUTPase)参与核苷酸代谢,已被确定为抗疟药发展的有希望的目标。分析了针对恶性疟原虫dUTPase和完整寄生虫的化合物。在酶抑制和细胞测定之间观察到良好的相关性。鉴定出与先前报道的抑制剂相比,无环尿嘧啶衍生物显示出更大或更相似的效力,并且通常选择性提高。此处报道的针对恶性疟原虫酶的活性最高的化合物的K(i)为0.2 microM。分子模型研究为观察到的活动提供了很好的理由。初步的ADME研究表明,某些先导化合物是类药物分子。这些化合物是进一步研究恶性疟原虫dUTPase以开发急需的新型抗疟药的有用工具。
