enantioselective synthesis of (4aR,5S,8aS)-configured decahydroquinoxalines 5–8 was developed. Physicochemical and pharmacological properties were fine-tuned by structural modifications in the arylacetamide and amine part of the pharmacophore as well as in the amine part outside the pharmacophore. The decahydroquinoxalines 5–8 show single-digit nanomolar to subnanomolar κ-opioid receptor affinity, full
为了发展限制到周边新颖κ激动剂,(4a的diastereo-和对映选择性合成- [R,5小号,8α小号)构型decahydroquinoxalines 5 - 8被开发。通过对药效基团的芳基乙酰胺和胺部分以及药效基团外的胺部分进行结构修饰,可以对生理化学和药理特性进行微调。所述decahydroquinoxalines 5 - 8示出的个位数纳摩尔至亚纳摩尔κ阿片受体的亲和力,完全κ激动活性在[ 35 S]GTPγS测定法,并用μ高选择性,δ,σ 1,σ 2受体以及NMDA受体的PCP结合位点。几种类似物对外周具有选择性。在两种皮炎小鼠模型中研究了局部应用后5 – 8的抗炎活性。含有(S)构型的羟基吡咯烷环的甲磺酰胺8a被确定为对外周有选择性的强效(K i = 0.63 nM)和高度选择性的κ激动剂(EC 50 = 1.8 nM),具有急性剂量依赖性的抗炎活性和慢性皮肤发炎。
