previously reported the synthesis, in vitro and in silico activities of new GABAanalogues as inhibitors of the GABA-AT enzyme from Pseudomonas fluorescens, where the nitrogen atom at the γ-position is embedded in heterocyclic scaffolds. With the goal of finding more potent inhibitors, we now report the synthesis of a new set of GABAanalogues with a broader variation of heterocyclic scaffolds at the
