title: [Structure-activity relationships of analgesics].
abstract: With morphine or codeine derivatives and different classes of synthetic compounds (pethidine, methadone, morphinane, benzomorphinane, etc.) there are correlations between structure and analgesic effects on the basis of common structural elements. Such findings can be helpful in obtaining information about the effects of different receptors and help to explain their mode of action.
