DBU-assisted cyclorelease elimination: combinatorial synthesis and gamma-glutamyl cysteine synthetase and glutathione-S-transeferase modulatory effect of C-nucleoside analogs.
A combinatorial library of 60C- nucleoside analogs was synthesized by sequential coupling of building blocks followed by cyclative cleavage with DBU in an efficient manner. Only DMSO soluble compounds were tested for their modulatory effect against filarial gamma-glutamyl cysteine synthetase (gamma-GCase) and glutathione-S-transeferases (GSTs). Several compounds were found to be weak inhibitors of filarial gamma-GCase, whereas, most of them stimulated filarial GSTs.
