promising antiviral activity. In this manuscript, the structure-activity relationship study was expanded to synthesis of isothiazolo[4,3-b]pyridines with modifications of the pyridine moiety. This effort led to the discovery of an isothiazolo[4,3-b]pyridine derivative with a 3,4-dimethoxyphenyl residue at position 5 that displayed low nanomolar GAK binding affinity and antiviral activity against dengue
以前,我们报道了3,6-二取代异噻唑并[4,3-b]吡啶的发现,它是有效的和选择性的细胞周期蛋白G相关激酶(GAK)抑制剂,具有有希望的抗病毒活性。在该手稿中,结构-活性关系研究扩展到合成具有吡啶部分修饰的异噻唑并[4,3-b]吡啶。这项工作导致发现了在位置5具有3,4-二甲氧基苯基残基的异噻唑并[4,3-b]吡啶衍生物,该衍生物显示出低的纳摩尔GAK结合亲和力和抗登革热病毒的抗病毒活性。
