sulfonyloxy-5-arylidene thiazolidine-2,4-dione derivatives were synthesized and screened in vitro for PTP1B inhibitory activity and in vivo for anti-hyperglycemic activity. The introduction of aryl/alkyl sulfonate ester moiety was anticipated to yield PTP1B inhibitors with significant potency. Docking results revealed their bidentate nature of binding, and further helped in understanding the binding mode of ligands
