2023年1月31日 · 食欲素(Orexins)可分为食欲素A (OXA,也可称下丘脑分泌素-1)和食欲素B (OXB,也可称下丘脑分泌素-2)两种神经肽。 OXA和OXB由同一个前食欲素在下丘脑外侧和后丘脑的神经元内切割形成,并分布整个大脑。 食欲素与其受体结合后,可促促进食欲,使机体从 睡眠 到清醒,调节奖赏机制和情绪等生理过程。 02、受体. 食欲素受体有两种,分别为食欲素1型受体(OX1R)和食欲素2型受体(OX2R)。 这两种受体与食欲素的亲和力有所不同。 OXA与两 …
Orexin Receptor Antagonists as Emerging Treatments for …
We discuss the actions of orexin receptor antagonists, including selective OX1R antagonists (SORA1s), selective OX2R antagonists (SORA2s), and dual OX1/2R antagonists (DORAs), in the treatment of these disorders based on both preclinical and clinical evidence.

2015年9月16日 · OX 1 R has been shown to drive apoptosis in human colon cancer cells, and treatment with orexins dramatically slowed the growth and even reversed the development of established tumors. OX 1 R agonists are therefore also …
Orexin Receptor Antagonists | Current Sleep Medicine Reports
2017年11月13日 · Based on rodent studies, it is clear that the OX2R is the primary target mediating sleep promotion by DORAs. We briefly review preclinical and clinical data of OXR antagonists in situations of unperturbed and perturbed sleep, e.g., insomnia and various neurological diseases.
Regulatory effect of orexin system on various diseases through …
2023年3月16日 · Like most GPCR-mediated pathways, orexins first bind to OXR, activating at least three G protein subtypes (Gq/11, Gi/o, and Gs) or other proteins (beta-repressor). These effectors subsequently regulate phospholipases, ion channels, and protein kinases, ultimately triggering the activation of various downstream signaling pathways [ 14 ].
