                                    Phenyl thiazole hydrazone derivatives 1-21 have been synthesized and screened for their in vitro antiglycation activity. Hydrazones 1-21 displayed assorted antiglycation activities having IC50 values in the range of 187.61 +/- A 1.12-886.98 +/- A 5.29 A mu M as compared to standard rutin (IC50 = 269.07 +/- A 3.79 A mu M). Compounds 5 (IC50 = 187.61 +/- A 1.12 A mu M), 3 (IC50 = 191.92 +/- A 3.08 A mu M), 4 (IC50 = 193.77 +/- A 3.06 A mu M), 6 (IC50 = 217.90 +/- A 2.48 A mu M), 15 (IC50 = 221.98 +/- A 2.34 A mu M), 2 (IC50 = 226.59 +/- A 1.19 A mu M), 21 (IC50 = 229.67 +/- A 1.95 A mu M), 18 (IC50 = 231.09 +/- A 0.38 A mu M), 12 (IC50 = 242.94 +/- A 2.05 A mu M), and 1 (IC50 = 264.22 +/- A 5.60 A mu M), respectively, showed excellent antiglycation activities superior to standard rutin. Compound 17 (IC50 = 269.94 +/- A 1.11 A mu M) demonstrated a comparable activity to the standard. Compounds 7, 8, 9, 10, 11, 13, 14, and 16 exhibited weaker activities than standard. However, compounds 19 and 20 showed no activity. When evaluated for cytotoxicity against rat fibroblast cell line (3T3 cell line), all compounds were found to be non-toxic in cellular model.
