A new series of substituted aryl-4- thiazolidinones were prepared by cyclocondensation of ketoazomethines and thioglycolic acid. Ketoazomethines were synthesized by condensation of phenyl glyoxal (prepared by partial oxidation of acetophenone) and various Para-substituted anilines. The synthesized compounds were identified by elemental, spectral studies and screened for analgesic activity. https://biomedpharmajournal.org/vol2no2/synthesis-and-analgesic-activity-of-some-new-substituted-aryl-4-thiazolidinones/ Synthesis Ketoazomethines 4-thiazolidinones analgesic activity
