Nine sulphur and selenium heterosubstituted isomers of N,N-diethylcarbamylcholine and carbaryl have been prepared and their inhibiting activity towards electric eel acetylcholinesterase (E.C. have been measured. The N,N-diethylcarbamylcholines acted only as reversible inhibitors, i.e. they could not carbamylate the enzyme. The reversible inhibition was of mixed type. Sulphur and selenium substitution had only marginal effects on Ki(0.2-0.3 mM) but reduced the value of K'i. The heterosubstituted carbaryl analogues were, with one exception, found to be irreversible inhibitors, about 100 times less potent than carbaryl.
