pyridine analogue of 1a revealed no intramolecular stacking interaction. The theoretical studies were evaluated in light of the observed receptor affinities, and the relevance of the solid-state geometry of 1a to the receptor-bound geometry was assessed. It is suggested that the stacked geometry found in the X-ray structure of 1a does not represent a conformation that is relevant to that bound at the histamine
组胺H 2受体拮抗剂的呋喃环3-氨基-4-[[2-[[[5-[([二甲基氨基)甲基] -2-呋喃基]-甲基]硫代]乙基]氨基] -1,2,5用噻吩,吡啶,苯和吡咯代替1-噻二唑一氧化物(1a)。这些类似物的相对受体亲和力通过体外和体内技术估算。建立了通过1a的单晶X射线分析观察到的堆叠相互作用的理论模型,并评估了进入这种相互作用的能力。对1a的吡啶类似物的X射线分析表明没有分子内堆积相互作用。根据观察到的受体亲和力对理论研究进行了评估,并评估了1a固态几何形状与受体结合几何形状的相关性。
