The effects of the aldehyde dehydrogenase inhibitors disulfiram, coprine and cyanamide on enzymes involved in the metabolism of biogenic aldehydes in rat liver and brain were studied.
None of the drugs caused any changes in the activities of aldehyde reductase and monoamine oxidase in brains in vivo.

Atherosclerosis. 2001 Oct;158(2):339-50.

The formation of HNA was inhibited by cyanamide, indicating that the acid is derived from an aldehyde dehydrogenase (ALDH)-catalyzed pathway.
The formation of GS-DHN appears to be due aldose reductase (AR)-catalyzed reduction of glutathionyl 4-hydroxynonanal (GS-HNE), since inhibitors of AR (tolrestat or sorbinil) prevented GS-DHN formation, and increased the fraction of the glutathione conjugate remaining as GS-HNE.

Sorbinil, an aldose reductase (AR) inhibitor, attenuated GS-DHN levels and cyanamide, an aldehyde dehydrogenase inhibitor, decreased formation of HNA.

Further metabolism of the GS-HNE conjugate involves aldose reductase-mediated reduction, a reaction catalyzed in vitro by homogenous cardiac aldose reductase.
When exposed to sorbinil, an inhibitor of aldose reductase, no GS-DHN was recovered in the coronary effluent, and treatment with cyanamide, an inhibitor of aldehyde dehydrogenase, attenuated 4-hydroxy-2-nonenoic acid formation.

Inhibitors of aldehyde or alcohol dehydrogenase, i.e., cyanamide and 4-methyl pyrazole, had no effect on the formation of HNA and GS-DHN, indicating that these enzymes are not significant participants in the erythrocyte HNE metabolism.
