conducting concise and high-yielding syntheses. The biological activity of obtained compounds was assessed in terms of potency (EC50) and efficacy (Emax) for arrestin recruitment. Finally, molecular modelling and simulation were used to explore binding characteristics of 5-oxo-ETE and derivatives with the aim to rationalize biological activity. Our data suggest that the tested 5-oxo-ETE derivatives (i) insert
氧杂二十烷酸受体1(OXER1)是G蛋白偶联受体(GPCR)家族的成员,并参与炎症过程和致癌作用。因此,它是药理学干预的有吸引力的靶标。本研究旨在使用与天然激动剂5-oxo-ETE相关的化学探针阐明OXER1调控的分子基础。第一步,通过进行简洁,高产的合成,获得了5-oxo-ETE及其密切相关的衍生物(5-oxo-EPE和4-oxo-DHA)。根据效力(EC 50)和功效(E max)进行逮捕。最后,通过分子建模和模拟研究了5-氧代-ETE及其衍生物的结合特性,以合理化生物活性。我们的数据表明,经过测试的5-oxo-ETE衍生物(i)快速插入膜中;(ii)通过跨膜螺旋(TMs)5和6从膜侧进入受体,并且(iii)通过差异来驱动药效和功效与TM5和7相互作用。最重要的是,我们发现5-氧-ETE(1a)的甲酯显示出比天然激动剂(1)更高的最大响应。相反,将5-oxo基团移至4位会导致非活性化合物(4-oxo
