                                    Novel pyrazolyl-2,4-thiazolidinediones were prepared via the reaction of appropriate pyrazolecarboxaldehydes with 2,4-thiazolidinediones and substituted benzyl-2,4-thiazolidinediones. The resultant compounds were first evaluated for their anti-inflammatory and neuroprotective properties in vitro. The active compounds were further studied in vivo by using the formalin-induced paw edema and the turpentine oil-induced granuloma pouch bioassays. We identified four novel compounds that showed protective effects in vitro at non-toxic concentrations, and were also effective in the animal models of acute and sub-acute inflammation.
