2-Aminopyridine-3,5-dicarbonitrile compounds were previously identified as mimetics of dominant-negative prion protein mutants and inhibit prion replication in cultured cells. Here, we report findings from a comprehensive structure-activity relationship study of the 6-aminopyridine-3,5-dicarbonitrile scaffold. We identify compounds with significantly improved bioactivity (approximately 40-fold) against
2-氨基吡啶-3,5-二甲腈化合物以前被鉴定为显性负病毒蛋白突变体的模拟物,并抑制病毒在培养细胞中的复制。在这里,我们报告从6-氨基吡啶-3,5-二甲腈支架的全面的结构-活性关系研究中发现的结果。我们确定了具有明显改善的生物活性(约40倍)的抗感染性ion病毒同工型(PrPSc)复制和合适的药代动力学特征的化合物,以保证在病毒疾病的动物模型中进行评估。
