synthesised as mimics of an R2/2(8) motif, which occurs in one crystal polymorph of sulfathiazole and in several polymorphs of sulfapyridine. When present in crystallisations of sulfathiazole and sulfapyridine, these mimics were found to have little or no effect under crystallisation conditions that favour the formation of polymorphs not containing R2/2(8) motifs. However, the mimics were found to completely

relative or absolute insulin hormone deficiency. Dipeptidyl peptidase- IV (DPP-IV) inhibitors are hypoglycemic agents augmenting the action of the incretin hormones that stimulate insulin secretion from the pancreatic beta cells. Objective: In this study, synthesis and biological evaluation of seven piperazinederivatives 3a-g was carried out. Methods: The synthesized molecules were characterized using
