In our continuation of the structure-based design of anti-trypanosomatid drugs, parasite- selective adenosine analogues were identified as low micromolar inhibitors of glyceraldehyde-3-phosphate dehydrogenase (GAPDH). Crystal structures of Trypanosoma brucei, Trypanosoma cruzi, Leishmania mexicana, and human GAPDH's provided details of how the adenosyl moiety of NAD+ interacts with the proteins, and this facilitated the ...
