lic (hetero)cycloalkanobenzene] analogs was designed, synthesized, and biologically evaluated in vitro to seek and identify potent and selective, small-molecules of nonpeptide NOP receptor antagonists, which resulted in the discovery of novel potent small-molecule 15 with high human NOP receptor selectivity over human mu receptor. The structure-activity relationship (SAR) of the potency and selectivity
Nociceptin / orphanin FQ(N / OFQ)和N / OFQ肽(NOP)受体在中枢神经系统(CNS),周围神经系统,免疫系统和周围组织等各个区域表达和分布。N / OFQ和NOP受体在生物体内的各种生理,病理生理,调节和失调机制中具有重要作用。NOP受体功能的激活和阻断都已显示出NOP受体激动剂和拮抗剂分别用于治疗各种疾病或病理生理状况的临床潜力。有效的和选择性的NOP受体激动剂/拮抗剂也是研究NOP受体N / OFQ系统介导的各种机制的有用工具。作为目前的研究,设计,合成了一系列(4-芳基哌啶取代的甲基)-[双环(杂)环烷烃苯]类似物,并在体外进行了生物学评估,以寻找和鉴定有效且选择性的非肽NOP受体拮抗剂小分子,从而得到了新型高效小分子15的发现,该分子具有比人类mu受体更高的人类NOP受体选择性。本发明类似物的hERG(人与人为相关的基因)钾离子通道结合亲和力的
