ABSTRACT
A new series of N-aryl/aralkyl substitued-2"-[[phenylsulfonyl][piperidin-1-yl]amino]acetamide [7a-k] was synthesized. These derivatives were geared up by the pairing of benzenesulfonyl chloride [4] with 1-aminopiperidine [5] under dynamic pH control in aqueous media to afford parent compound N-[Piperidin-1-yl] benzenesulfonamide [6], followed by the substitution at nitrogen atom with different electrophiles N-aryl/aralkyl-substituted-2-bromoacetamides [3a-k] in the presence of sodium hydride [NaH] and N,N-Dimethylformamide [DMF] to give a new series of Nsubstituted derivatives of acetamide [7a-k] bearing piperidine moiety. All the synthesized compounds were confirmed on the basis of IR, EIMS and 1H-NMR spectral data. The synthesized compounds were evaluated against acetylcholinesterase and butyrylcholinesterase [AChE and BChE] respectively and lipoxygenase [LOX] enzymes. Almost all the synthesized compounds displayed promising activity but few of them remained inactive against lipoxygenase enzymes.
