Dopamine sensitive adenylate-cyclase was studied in rat striatal homogenate after incubation with several analgesic drugs. The compounds we studied are 3 to 100 times more effective than morphine in producing analgesia or catalepsy. These results suggest that the inhibitory effect of these compounds on DA-sensitive adenylate-cyclase roughly parallels their capacity to produce catalepsy and reflects their analgesic potency in rats.
