Synthetic derivatives of spiro[pyrrolidinyl-3,3'-oxindole] alkaloids (coerulescine analogues) were investigated as new ligands for aminergic G-protein coupled receptors (GPCRs). The chemical starting point 2'-phenylspiro[indoline-3,3'-pyrrolidin]-2-one scaffold was identified by virtual fragment screening utilizing ligand- and structure based methods. As a part of the hit-to-lead optimization a structure-activity
研究了螺[吡咯烷基-3,3'-羟吲哚]生物碱的合成衍生物(蓝藻碱类似物)作为胺能G蛋白偶联受体(GPCR)的新配体。通过基于基于配体和结构的方法的虚拟片段筛选,确定了化学起始点2'-苯基螺并[吲哚啉-3,3'-吡咯烷基] -2-one支架。作为从头至尾优化的一部分,进行了结构-活性关系分析,以探索不同取代的2'-苯基衍生物,引入苯基磺酰基药效团并检查相应的还原螺[吡咯烷-3,3'-二氢吲哚]脚手架。优化过程导致对5-HT 1受体具有亚微摩尔亲和力的配体,可以用作进一步优化的可行线索。
