hydrophobic requirements for recognition forces of the receptor site. According to the clues provided by this 3D-QSAR analysis, we designed and synthesized a series of new analogues of methanesulfonamido phenylethylamine (VIa-i). Pharmacological assay indicated that the effective concentrations of delaying the functional refractory period (FRP) 10ms of these new compounds have a good correlation with
III类抗心律不齐药物选择性地延迟了有效不应期(ERP),并增加了跨膜动作电位持续时间(APD)。根据我们以前的研究,通过CoMFA和CoMSIA的3D-QSAR技术研究了17种甲磺酰胺基苯乙胺类似物。3D-QSAR模型具有良好的预测能力,可以描述受体位点识别力的空间,静电和疏水性要求。根据此3D-QSAR分析提供的线索,我们设计并合成了一系列新的甲磺酰胺基苯乙胺(VIa-i)类似物。药理分析表明,这些新化合物的功能性不应期(FRP)延迟10毫秒的有效浓度与3D-QSAR预测值具有良好的相关性。值得注意的是,在化合物VIc的microM中,延迟FRP的最大变化百分比远高于多芬替利。结果表明3D-QSAR模型是可靠的。
