The purpose of this study was to evaluate the effect of GP inhibitor as a potential pharmaceutical target on MI/R injury. Four different structural types of novel compounds (I, II, III, and IV) were designed and synthesized, obtaining 31 novel GP inhibitors. SAR studies revealed that the conjugates of 5-chloroindole with benzo six-membered heterocyclic were found to elevate the activity. In particular
本研究的目的是评估 GP 抑制剂作为潜在药物靶点对 MI/R 损伤的影响。设计并合成了四种不同结构类型的新型化合物(Ⅰ、Ⅱ、Ⅲ、 Ⅳ ),获得了31种新型GP抑制剂。SAR 研究表明,发现 5-氯吲哚与苯并六元杂环的缀合物可提高活性。特别是,化合物IIIh (IC 50 = 0.21 ± 0.03 µM) 作为一种有效的 RMGPa 衍生物出现,其效力比 PSN-357 低约 2 倍。为了筛选出一种化合物用于体内活性测试后,我们进一步进行了对三种不同GPa亚型(HLGPa、HMGPa和HBGPa)的抑制实验和相应的亲和实验。因此,化合物IIIh对上述三种 GP 亚型均表现出较强的抑制活性,尤其是对 HBGPa(IC 50 = 0.09 ± 0.002 µM),与阳性对照 ingliforib(IC 50 = 0.16 ± 0.02 µM)比较接近. 化合物IIIh对HBGPa的亲和力比HLGPa高4
