Urotensin-II was originally isolated from the goby urophysis in the 1960s as a vasoactive peptide with a prominent role in cardiovascular homeostasis. The identification of human isoform of urotensin-II and its specific UT receptor by Ames et al. in 1999 led to investigating the putative role of the interaction U-II/UT receptor in multiple pathophysiological effects in humans. Since urotensin-II is widely expressed in several peripheral tissues including cardiovascular system, the design and development of novel urotensin-II analogues can improve knowledge about structure-activity relationships (SAR). In particular, since the modulation of the U-II system offers a great potential for therapeutic strategies related to the treatment of several diseases, like cardiovascular diseases, the research of selective and potent ligands at UT receptor is more fascinating. In this paper, we review the developments of peptide and nonpeptide U-II structures so far developed in order to contribute also to a more rational and detectable design and synthesis of new molecules with high affinity at the UT receptor.
尾加压素II最初于20世纪60年代从虎鱼的尾垂体中分离出来,是一种血管活性肽,在心血管稳态中起重要作用。1999年,艾姆斯等人鉴定出人类尾加压素II同工型及其特异性UT受体,从而开始研究U-II/UT受体相互作用在人类多种病理生理效应中的假定作用。由于尾加压素II在包括心血管系统在内的多个外周组织中广泛表达,新型尾加压素II类似物的设计和开发可以增进对构效关系(SAR)的了解。特别是,由于U-II系统的调节为与多种疾病(如心血管疾病)治疗相关的治疗策略提供了巨大潜力,因此对UT受体选择性和强效配体的研究更具吸引力。在本文中,我们回顾了迄今为止已开发的肽类和非肽类U-II结构的进展,以便也有助于更合理和可检测地设计和合成对UT受体具有高亲和力的新分子。
