enzyme, which is a target for inhibition of the conversion of glycogen to glucose-1-phosphate. In this study we report the design and synthesis of 14 new pyridone derivatives, and seek to extend the SAR analysis of these compounds. The SAR revealed the minor influence of the amide group, importance of the pyridone ring both spatially around the pyridine ring and for possible π-stacking, and confirmed
糖原磷酸化酶(GP)是一种功能活跃的二聚酶,是抑制糖原向1磷酸葡萄糖的转化的靶标。在这项研究中,我们报告了14种新的吡啶酮衍生物的设计和合成,并寻求扩展这些化合物的SAR分析。SAR揭示了酰胺基的较小影响,吡啶环在空间上在吡啶环周围以及对于可能的π堆积的重要性,并证实了优先选择包含3,4-二氯苄基部分作为吡啶酮支架的书端。在探索二聚体策略作为SAR分析的一部分后,确定了第一个扩展的基于2-氧代-二氢吡啶基-3-基酰胺纳米摩尔的GPa抑制剂(IC 50 = 230和260 nM)。
