Nucleoside analogues that have 6-chloropurine as the nucleobase were synthesized and evaluated for anti-SARS-CoV activity by plaque reduction and yield reduction assays in order to develop novel anti-SARS-CoV agents. Among these analogues, two compounds, namely, 1 and 11, exhibited promising anti-SARS-CoV activity that was comparable to those of mizoribine and ribavirin, which are known anti-SARS-CoV
合成了具有6-氯嘌呤作为核碱基的核苷类似物,并通过噬斑减少和产量减少分析评估了其抗SARS-CoV活性,以开发新型抗SARS-CoV药物。在这些类似物中,两种化合物,即1和11,显示出有希望的抗SARS-CoV活性,与已知的抗SARS-CoV药物米索立滨和利巴韦林的活性相当。此外,我们观察到了几种SAR趋势,例如6-氯嘌呤部分的抗病毒作用,未保护的5'-羟基和苯甲酰化的5'-羟基。
