恶唑并[3,4-a]吡嗪衍生物的结构-活性关系研究导致发现具有强大体内活性的新型神经肽 S 受体拮抗剂
摘要:
Neuropeptide S 通过与其 G 蛋白偶联受体(称为神经肽 S 受体 (NPSR))相互作用来调节重要的神经生物学功能,包括运动、焦虑和药物滥用。 NPSR 拮抗剂可潜在用于治疗药物滥用疾病,迫切需要新的有效治疗方法。体外有效的 NPSR 拮抗剂已被发现,然而,需要进一步优化其体内药理学特性。这项工作描述了恶唑并[3,4- a ]吡嗪类的一系列新 NPSR 拮抗剂。与该领域的参考药理学工具SHA-68相比,胍衍生物16在体外表现出纳摩尔级活性,在体内效力提高了 5 倍。化合物16可以被认为是研究 NPSergic 系统转化潜力的新工具。还进行了深入的分子建模研究,以获得对观察到的结构-活性关系的新见解,并提供配体/NPSR相互作用的更新模型。

side-chain functionalities of peptidic alpha-helices. The synthesis of 1,4-dipiperazino benzenes, using stepwise transition metal-catalyzed N-arylation of chiral piperazines to a central benzene core is reported. The structure determination by X-ray crystallography reveals a geometrical arrangement of the hydrophobic side chains resembling the orientation of key i, i + 3, and i + 7 positions in a peptidic
Efficient one-pot synthesis of enantiomerically pure <i>N</i>-protected-α-substituted piperazines from readily available α-amino acids

日期:——
A new pathway towards enantiomerically pure 3-substituted piperazines, bearing a benzyl protectinggroup, has been developed in good overall yields (83–92%), starting from commercially available N-protected aminoacids. The methodology represents an efficient and simple one-pot procedure, employing a synthetic sequence consisting of an Ugi-4 component reaction, a Boc-deprotection, an intramolecular
