SARS-CoV主要蛋白酶与HIV、精神病和寄生虫药物(洛匹那韦、利托那韦、硝氯胺和丙嗪)的结合分析表明,这些现有药物可作为设计SARS-CoV蛋白酶抑制剂的起点。sars相关冠状病毒(SARS-CoV)主蛋白酶是病毒多蛋白加工的关键酶。为了能够基于结构设计针对SARS-CoV主要蛋白酶的药物,我们预测了它与现有的HIV、精神病和寄生虫药物(洛匹那韦、利托那韦、硝氯胺和丙嗪)的结合口袋和亲和力,这些药物显示出抑制SARS-CoV复制的迹象。我们的研究结果表明,这些药物和另外两种HIV抑制剂(PNU和UC2)可以作为设计SARS-CoV蛋白酶抑制剂的模板。
The binding analysis of SARS-CoV main proteinase with HIV, psychotic and parasite drugs (lopinavir, ritonavir, niclosamide and promazine) suggests that these existing drugs can be used as starting points for designing SARS-CoV proteinase inhibitors. The SARS-associated coronavirus (SARS-CoV) main proteinase is a key enzyme in viral polyprotein processing. To allow structure-based design of drugs directed at SARS-CoV main proteinase, we predicted its binding pockets and affinities with existing HIV, psychotic and parasite drugs (lopinavir, ritonavir, niclosamide and promazine), which show signs of inhibiting the replication of SARS-CoV. Our results suggest that these drugs and another two HIV inhibitors (PNU and UC2) could be used as templates for designing SARS-CoV proteinase inhibitors.
