high affinity and selectivity at the DA D3 receptor is reported here. Compounds endowed with high selectivity over the hERG channel were identified and their pharmacokinetic properties thoroughly analyzed. A few derivatives with appropriate developability characteristics were selected for further studies and progression along the screening cascade. In particular, derivative 60a, (DA D3 pKi = 8.4, DA D2
本文报道了一系列新的1,2,4-三唑基八氢吡咯并[2,3- b ]吡咯在DA D3受体上表现出高亲和力和选择性。鉴定了在hERG通道上具有高选择性的化合物,并对其药代动力学特性进行了全面分析。选择了一些具有适当可显影性的衍生物,以进一步研究并沿着筛选级联进行。特别地,衍生物60a(DA D3 p K i = 8.4,DA D2 p K i = 6.0和hERG fp K i = 5.2)显示出平衡的分布,并且围绕该分子进行进一步的改进。
