Abstract
Methyl groups of 6-methylnicotinic acid and 2,6-dimethylnicotinic acid were deuterated by an H-D exchange reaction under conditions of 1% NaOD/D(2)O on heating. With a condensation reaction between the D-labeled nicotinic acid derivative and N-hydroxysuccinimide with 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride, the nicotinoylating agents, 1-(6-methyl[D(3)]nicotinoyloxy)succinimide (2c) and 1-(2,6-dimethyl[D(6)]nicotinoyloxy)succinimide (2f) were prepared. Both D-labeled nicotinoylating agents and their unlabeled counterparts quantitatively modified the N-terminal of protein.
