  摘要：

  阿片类激动剂是公认的镇痛剂，广泛用于治疗急性和慢性疼痛。然而，它们的效率伴随着极大影响副作用的代价，这些副作用与其长期使用有着内在的联系。为了解决这些问题，设计的多配体 (DML) 通过共同靶向涉及伤害感受的阿片类和非阿片类信号通路提供了一种有前景的策略。尽管与物质 P (SP)/神经激肽 1 (NK1) 系统密切相关，该系统被广泛用于疼痛治疗，但神经激肽受体 NK2 和 NK3 迄今为止在此类 DML 中被忽视。在此，报道了一系列新设计的阿片类激动剂-NK2 或-NK3 拮抗剂。一系列报道的肽、假肽、d -Arg-Phe-Lys-NH 2 ) 和双重 μ/δ 阿片类激动剂 H-Dmt- d -Arg-Aba-βAla-NH 2 (KGOP01)。阿片类药物结合测定明确表明，只有SBL-OPNK-5、SBL-OPNK-7和SBL-OPNK-9 的杂交体，带有 KGOP01 支架，保守的纳摩尔范围

  Discovery of a Novel Class of Selective Non-Peptide Antagonists for the Human Neurokinin-3 Receptor. 2. Identification of (S)-N-(1-Phenylpropyl)-3-hydroxy-2- phenylquinoline-4-carboxamide (SB 223412)

  摘要：

  Optimization of the previously reported 2-phenyl-4-quinolinecarboxamide NK-3 receptor antagonist 14, with regard to potential metabolic instability of the ester moiety and affinity and selectivity for the human neurokinin-3 (hNK-3) receptor, is described. The ester functionality could be successfully replaced by the ketone (31) or by lower alkyl groups (Et, 21, or n-Pr, 24). Investigation of the substitution pattern of the quinoline ring resulted in the identification of position 3 as a key position to enhance hNK-3 binding affinity and selectivity for the hNK-3 versus the hNK-2 receptor. All of the chemical groups introduced at this position, with the exception of halogens, increased the hNK-3 binding affinity, and compounds 53 (3-OH, SE 223412, hNK-3-CHO binding K-i = 1.4 nM) and 55 (3-NHz, hNK-3-CHO binding K-i = 1.2 nM) were the most potent compounds of this series. Selectivity studies versus the other neurokinin receptors (hNK-8-CHO and hNK-1-CHO) revealed that 53 is about 100-fold selective for the hNK-3 versus hNK-2 receptor, with no affinity for the hNK-1 at concentrations up to 100 mu M. In vitro studies demonstrated that 53 is a potent functional antagonist of the hNK-3 receptor (reversal of senktide-induced contractions in rabbit isolated iris sphincter muscles and reversal of NKB-induced Ca2+ mobilization in CHO cells stably expressing the hNK-3 receptor), while in vivo this compound showed oral and intravenous activity in NK-3 receptor-driven models (senktide-induced behavioral responses in mice and senktide-induced miosis in rabbits). Overall, the biological data indicate that (S)-N-(1-phenylpropyl)-3-hydroxy-2-phenylquinoline-4-carboxamide (53, SE 223412) may serve as a pharmacological tool in animal models of disease to assess the functional and pathophysiological role of the NK-3 receptor and to establish therapeutic indications for non-peptide NK-3 receptor antagonists.
