A series of cyclic and acyclic nucleoside analogues derived from 3-hydroxy-4-pyridinone were synthesized using the Vorbruggen reaction. Iron chelation studies, and antiviral evaluation against a broad panel of viruses, were performed. The pK(a) value of ligand 25 and the stability constant of the corresponding iron(III) complex were compared to those of deferiprone. The pFe(3+) values were found to
使用Vorbruggen反应合成了一系列衍生自3-羟基-4-吡啶酮的环状和无环核苷类似物。进行了铁螯合研究和针对多种病毒的抗病毒评估。将配体25的pK(a)值和相应的铁(III)配合物的稳定性常数与去铁酮进行了比较。发现pFe(3+)值相似。一些化合物对野生型HSV-1和HSV-2以及对胸腺嘧啶激酶缺陷的HSV-1菌株均显示中等活性。这些结果表明该组核苷类似物的新型作用方式。
