Various 2- and 3-haloallylamines were synthesized and evaluated as inhibitors of the quinone-dependent bovine plasma amine oxidase (BPAO). 3-Haloallylamines, which were previously found to be good inhibitors of the flavin-dependent mitochondrial monoamine oxidase (MAO), exhibited a time-dependent inactivation of BPAO, with the 2-phenyl analogs being more potent than the 2-methyl analogs. No plateau of enzyme activity loss was observed, suggestive of a lack of competitive partitioning to normal turnover. The (E)- and (Z)-2-phenyl-3-fluoro analogs were the most potent (low μM IC50s), with the corresponding 3-bromo and 3-chloro analogs being >10-fold less potent. In each case, the Z-isomers were more potent than the E-isomers, the reverse of the configurational inhibitory preference observed with MAO. In contrast to the 2-phenyl analogs, 3-phenyl-2(or 3)-chloroallylamines displayed a partitioning behavior, consistent with these being both substrates and inactivators of BPAO.
