A series of fourteen novel thiazolidine-2,4-dione derivatives clubbed with pyrazole moiety were synthesized via four step reaction procedure. Reactions were monitored by thin layer chromatography and were characterized by physicochemical and spectrophotometric (IR, Mass, ¹HNMR and ¹³CNMR) analysis. The spectral data were in good agreement with their structures. The title compounds were docked against peroxisome proliferated activated receptors (PPAR-γ) and alpha-amylase and further evaluated for in vivo and in vitro antidiabetic, in vitro anti-inflammatory and antioxidant activities. Compound GB14 exhibited significant blood glucose lowering activity and was also found to be active inhibitor of alpha-amylase. Compound GB7 was found to be potent anti-inflammatory agent in terms of reducing inflammatory markers (TNF-α, IL-β, MDA) and also showed antioxidant activity to good extent. Therefore, these compounds may be considered as promising candidates for the development of new antidiabetic agents.
