The use of natural product scaffolds as leads in the search for trypanothione reductase inhibitors. Bioorganic & medicinal chemistry, 2008, Jul-15, Volume: 16, Issue:14 Twenty-three heterocyclic compounds were evaluated for their potential as trypanothione reductase inhibitors. As a result, the harmaline, 10-thiaisoalloxazine, and aspidospermine frameworks were identified as the basis of inhibitors of Trypanosoma cruzi trypanothione reductase. Two new compounds showed moderately strong, linear competitive inhibition, namely N,N-dimethyl-N-[3-(7-methoxy-1-methyl-3,4-dihydro-9H-beta-carbolin-9-yl)propyl]amine (15) and 1,3-bis[3-(dimethylamino)propyl]-1,5-dihydro-2H-pyrimido[4,5-b][1,4]benzothiazine-2,4(3H)-dione (21), with K(i) values of 35.1+/-3.5microM and 26.9+/-1.9microM, respectively. Aspidospermine (25) inhibited T. cruzi TryR with a K(i) of 64.6+/-6.2microM. None of the compounds inhibited glutathione reductase. Their toxicity toward promastigotes of Leishmania amazonensis was assessed.
