Abstract
A series of 2'-benzamido-2'-deoxyadenosine analogues were synthesized in an effort to find new lead structures for the treatment of sleeping sickness. The 2'-deoxy-2'-(3-methoxybenzamido)adenosin (1h) was proved to be a selective inhibitor of the parasite glyceraldehyde 3-phosphate dehydrogenase which confirms the modeling studies. The solution-state conformation of 2'-(thiophene-2-carboxamido) analogue 1d demonstrates a 2'-endo conformation, an orientation of the thiophene ring under the ribose moiety, and the base part occupying a 'syn'/'anti' equilibrium.
