Easson and steadman hypothesis

WebIn 1933, Easson and Stedman suggested “three of the groups linked to the asymmetric carbon atom in an optically active (chiral) drug are concerned in its attachment to its specific receptor in the tissue.” 1 According to this oversimplified model, the substituents of the active or more potent enantiomer are oriented in a way that is complementary … WebAccording to Easson–Stedman hypothesis, if binding ions are specific for one enantiomer, then a threepoint attachment must occur between the enantiomer and the asymmetric surface of the receptor, since only one of the entantiomers will fit, and the other one is only capable of a two-point attachment as shown in Figure 8.1.
