series of 37 benzolactam derivatives were synthesized, and their respective affinities for the dopamine D2 and D3 receptors evaluated. The relationships between structures and binding affinities were investigated using both ligand‐based (3D‐QSAR) and receptor‐based methods. The results revealed the importance of diverse structural features in explaining the differences in the observed affinities, such as
合成了一系列37种苯并内酰胺衍生物,并评估了它们各自对多巴胺D 2和D 3受体的亲和力。使用基于配体的方法(3D-QSAR)和基于受体的方法研究了结构与结合亲和力之间的关系。结果表明,在解释所观察到的亲和力方面的差异(例如苯并内酰胺羰基氧的位置或化合物的总长度)时,各种结构特征的重要性。对于D 2和D 3,此类配体性质的最佳值略有不同即使结合位点表现出非常高的同源性,受体也是如此。我们解释通过氢键网络的在d中存在这些差异2受体这是在d缺席3受体并限制了结合口袋的尺寸,造成在螺旋7个残基变得不那么访问。这些结果对设计更有效和选择性更高的苯并内酰胺衍生物的意义进行了介绍和讨论。
