Abstract
PREVIOUS investigators have shown that human plasma cholinesterase is strongly inhibited by both lysergic acid diethylamide (LSD) and its 2-bromo derivative (BOL). The cholinesterases of other species were less sensitive to the effects of both these substances1–3. Recent reports described certain newer choline esters, namely, imidazoleacrylylcholine4 5 (murexine), imidazoleacetylcholine6 and imidazolepropionylcholine (dihydromurexine) which are hydrolysed most readily by human plasma cholinesterase7–10. These observations have led us to evaluate the possible relationship between cholinesterase inhibition by lysergic acid diethylamide and BOL and cholinesterase hydrolysis of dihydromurexine. Dihydromurexine was chosen as the model substrate because it is the most active of the three esters.
