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 …
