obtained from inhibitors to activators on GPCRs. Derivatives 2–5, 8, 15, 16 and 18–20 possessed moderate activation potency on GPCRs. Among them, derivatives 3–5, 16 and 19 presented significant activation potency on GPCRs with EC50 values in the range of 1.18–1.91 nM. Derivatives 6, 11, 14 and 18 showed significant inhibitory potency on GPCRs with IC50 values in the range of 1.26-1.38 nM. Moreover,
一系列瑞香素(7,8-二羟基香豆素)衍生物的1-22合成了包括16种新化合物(1-5,7-14,18,21和22)和6种已知的化合物(6,15-17,19和20)。它们对G蛋白偶联受体(GPCR)的药理学活性通过双抗体夹心ELISA(DAS-ELISA)评价体外。从GPCR的抑制剂到活化剂获得了具有各种取代模式/基团的树香素衍生物。衍生物2-5,8,15,16和18-20在GPCR上具有中等的激活潜能。其中,衍生物3-5,16和19呈现在与EC的GPCR激活显著效力50个在1.18-1.91纳米的范围内的值。衍生物6,11,14和18显示与IC的GPCR显著抑制效力50个在1.26-1.38纳米的范围内的值。此外,详细讨论了瑞香素衍生物的构效关系(SARs)。新的基于daphnetic的GPCRs激活剂和抑制剂具有潜在的潜力,可作为治疗代谢性疾病的未来候选药物。
