To validate PDE4 inhibitors as novel therapeutic agents against vascular dementia (VaD), twenty-five derivatives were discovered from the natural inhibitor α-mangostin (IC50=1.31 μM). Hit-to-lead optimization identified a novel and selective PDE4 inhibitor 4e (IC50 = 17 nM), which adopted a different binding pattern from PDE4 inhibitors roflumilast and rolipram. Oral administration of 4e at a dose
为了验证PDE4抑制剂是抗血管性痴呆(VaD)的新型治疗剂,从天然抑制剂α-Mangostin(IC50 = 1.31μM)中发现了25种衍生物。逐项优化确定了一种新型的选择性PDE4抑制剂4e(IC50 = 17 nM),它采用了与PDE4抑制剂roflumilast和rolipram不同的结合方式。以10 mg / kg的剂量口服4e在VaD模型中显示出显着的治疗效果,并且不会对比格犬造成呕吐,表明其作为新型抗VaD剂的潜力。
