Studies on the effects of pyrogallol and the structurally related dopa decarboxylase inhibitor RO4-4602 on acetaldehyde metabolism.

Microanalytic procedures for the determination of AcH in whole blood from EtOH-intoxicated animals given PG or related drugs should utilize a hemolysis step in 0.5 N PCA in order to inhibit PG-dependent AcH production in vitro. Thiourea may also be included as an added protective measure. RO4-4602, a clinically important drug that contains a PG ring structure, is a moderate in vitro inhibitor of AldDH activity, comparable in potency to PG, chloral hydrate, or diethyldithiocarbamate.
