Benomyl (a non-thio fungicide) inhibits hepatic mitochondrial low-Km aldehyde dehydrogenase (mALDH or ALDH2) in ip-treated mice by 50% (IC50) at 7.0 mg/kg, which is surprisingly the same potency range as that for several dithiocarbamate fungicides (and the related alcohol abuse drug disulfiram) and thiocarbamate herbicides previously known for their alcohol-sensitizing action.

J Am Coll Cardiol. 2007 Dec 4;50(23):2226-32. Epub 2007 Nov 19.

In vivo GTN tolerance was mimicked in vitro by incubation of nontolerant vessels with the ALDH-2 inhibitor benomyl.

Liver mitochondrial low-Km aldehyde dehydrogenase (ALDH2, EC 1.2.1.3), the isoform responsible for the conversion of acetaldehyde to acetate, is inhibited by the sulfoxide bioactivation products of Et2NC (O) SMe (from the alcohol aversion drug disulfiram), Pr2NC (O) SEt (the herbicide S-ethyl N,N-dipropylthiocarbamate), and BuNHC (O) SMe (from the fungicide benomyl).

Mol Pharmacol. 2004 Dec;66(6):1372-82. Epub 2004 Aug 26.

The bioactivation-related metabolism of GTN to glyceryl-1,2-dinitrate by isolated RAW macrophages was reduced by the ALDH-2 inhibitors benomyl and daidzin, as well as by GTN at concentrations > 1 microM.

Two possible ALDH enzymes which might oxidize HNE in CNS mitochondria are ALDH2 and succinic semialdehyde dehydrogenase (SSADH/ALDH5A).
