Nucleoside hydrolase (NH) is a key enzyme in the purine salvage pathway. The purine specificity of the IAG-NH from Trypanosoma vivax is at least in part due to cation-π-stacking interactions. Guanidinium ions can be involved in cation-π-stacking interactions, therefore a series of guanidino-alkyl-ribitol derivatives were synthesized in order to examine the binding affinity of these compounds towards the target enzyme. The compounds show moderate to good inhibiting activity towards the IAG-NH from T. vivax.

A key enzyme within the purine salvage pathway of parasites, nucleoside hydrolase, is proposed as a good target for new antiparasitic drugs. We have developed N-arylmethyl-iminoribitol derivatives as a novel class of inhibitors against a purine specific nucleoside hydrolase from Trypanosoma vivax. Several of our inhibitors exhibited low nanomolar activity, with 1,4-dideoxy-1,4-imino-N-(8-quinolinyl)methyl-d-ribitol (UAMC-00115, Ki 10.8 nM), N-(9-deaza-adenin-9-yl)methyl-1,4-dideoxy-1,4-imino-d-ribitol (Ki 4.1 nM), and N-(9-deazahypoxanthin-9-yl)methyl-1,4-dideoxy-1,4-imino-d-ribitol (Ki 4.4 nM) being the three most active compounds. Docking studies of the most active inhibitors revealed several important interactions with the enzyme. Among these interactions are aromatic stacking of the nucleobase mimic with two Trp-residues, and hydrogen bonds between the hydroxyl groups of the inhibitors and amino acid residues in the active site. During the course of these docking studies we also identified a strong interaction between the Asp40 residue from the enzyme and the inhibitor. This is an interaction which has not previously been considered as being important.
