  • D-Lysergic acid diethylamide and D-2-bromolysergic acid diethylamide are competitive antagonists of the histamine activation of adenylate cyclase [ATP pyrophosphate-lyase (cyclizing); E.C.] in broken cell preparations of the hippocampus and cortex of guinea pig brain. The adenylate cyclase is linked to the histamine H2-receptor. Both D-lysergic acid diethylamide and D-2-bromolysergic acid diethylamide show topological congruency with potent H2-antagonists. D-2-Bromolysergic acid diethylamide is 10 times more potent as an H2-antagonist than cimetidine, which has been the most potent H2-antagonist reported, and D-lysergic acid diethylamide is about equipotent to cimetidine. Blockade of H2-receptors could contribute to the behavioral effects of D-2-bromolysergic acid diethylamide and D-lysergic acid diethylamide.
