The anti and syn isomers of tolvaptan-type compounds, N-benzoyl-5-hydroxy-1-benzazepines (5ac), were prepared in a stereocontrolled manner by biasing the conformation with a methyl group at C9 and C6, respectively, and the enantiomeric forms were separated. Examination of the affinity at the human vasopressin receptors revealed that the axial chirality (aS) plays a more important role than the central chirality at C5 in receptor recognition, and the most preferable form was shown to be (E,aS,5S).

托伐普坦型加压素受体配体:活性形式的轴向手性的重要作用。

所述顺式的托伐普坦类化合物的异构体,ñ -苯甲酰基-5-羟基-1-苯并吖庚因(5A - Ç),是在一个立体控制的方式通过偏压与在分别C9和C6,甲基构象制备,并且对映体形式被分离。对人血管加压素受体的亲和力研究表明,在受体识别中,轴向手性(a S)比C 5的中心手性更重要,并且最优选的形式为(E,a S,5 S)。
