-adrenoceptor (AR) antagonists, a novel class of coumarin (=2H-1-benzopyran-2-one) derivatives have been successfully designed and synthesized with high efficacies for α(1) -AR. These synthesized coumarin derivatives exhibited high efficacies towards α(1) -AR in in vitro pharmacological assays. Compared with prazosin (pK(i) value of 8.77), among those coumarins, tolylpiperazine-substituted derivatives, 7 and 8
根据一些尿液选择性α(1)肾上腺素能受体(AR)拮抗剂的三点药效基团,已经成功设计并合成了新型香豆素(= 2H-1-苯并吡喃-2-酮)衍生物。对于α(1)-AR。这些合成的香豆素衍生物在体外药理试验中显示出对α(1)-AR的高效率。与哌唑嗪相比(pK(i)值为8.77),在这些香豆素中,甲苯基哌嗪取代的衍生物7和8的pK(i)值分别为8.81和8.77。这些香豆素衍生物对α(1A)-肾上腺素受体的功效趋势通过密集的分子对接进一步合理化。我们的工作表明,设计的香豆素衍生物可以在体外抑制α(1)-AR。
