analogues were pure opioid receptor antagonists with no agonist activity. Compounds 1, 8, 9, 13, and 14 (Ke values 0.058–0.64 nM) are highly potent and highly selective for the κ relative to the μ and δ opioid receptors. Favorable calculated physiochemical properties were confirmed in rat PK studies, demonstrating brain penetration for selected compounds 1, 9, and 13. High κ opioid receptor potency and selectivity
动物药理研究表明,强效和选择性κ阿片受体拮抗剂有可能作为针对抑郁症,焦虑症和药物滥用(鸦片,酒精,尼古丁,可卡因)的药物治疗。我们最近报道了仅含一个碱性胺基团的铅化合物1是一类新型的κ阿片受体拮抗剂。合成类似物,并使用[ 35 S]GTPγS结合试验评估其体外阿片受体拮抗剂特性。所有类似物均为纯阿片受体拮抗剂,无激动剂活性。化合物1,8,9,13,和14(ķ Ë相对于μ和δ阿片受体,κ值为0.058–0.64 nM)对κ是高度有效和高度选择性的。有利计算物理化学性质在大鼠PK研究证实,这表明所选择的化合物的脑渗透1,9和13。高κ阿片受体的效能和选择性,以及对脑部渗透的高度有利的经计算的理化和PK特性,建议应考虑将这些化合物用于进一步开发。
