An irreversible competitive inhibitor hydroxynaphthaldehyde phosphate was synthesized that is highly selective against the glycolytic enzyme fructose 1,6-bisphosphate aldolase from Trypanosoma brucei (causative agent of sleeping sickness). Inhibition involves Schiff base formation by the inhibitor aldehyde with Lys 116 followed by reaction of the resultant Schiff base with a second residue. Molecular simulations indicate significantly greater molecular geometries conducive for nucleophilic attack in T. brucei aldolase than the mammalian isozyme and suggest Ser48 as the Schiff base modifying residue.
