神经肽S受体的拮抗剂被认为是治疗呼吸、睡眠、焦虑和成瘾性疾病的有前景的治疗剂。在这里,我们提出了一个新的系列的正构拮抗剂的SAR。神经肽S受体信号传导与Gq和Gs蛋白偶联,我们观察到该结构系列中的不同类似物可以选择性地拮抗这两种途径。许多G蛋白偶联受体通过多种途径传递信号。这些途径的选择性拮抗作用可能会导致更有针对性的药理学特征和治疗方法的发展。
Antagonists of the Neuropeptide S Receptor have been postulated as promising therapeutics in the treatment of respiratory, sleep, anxiety, and addictive disorders. Here we present the SAR of a new series of orthosteric antagonists. Neuropeptide S Receptor signaling is coupled to both Gq and Gs proteins, and we observe that different analogues in this structural series can selectively antagonize these two pathways. Many G-protein coupled receptors transduce signals through multiple pathways. Selective antagonism of these pathways may lead the way to the development of more targeted pharmacological profiles and therapies.
