Abstract:


Benzophenonehydrazone Schiff bases 1-25 were synthesized and their in vitro antiglycation potential has been studied. Out of twenty-five compounds, thirteen showed varying degrees of antiglycation activity with IC50 values ranging between 25.7 - 305 μM, if compared with the standard rutin (IC50 = 70.5 ± 0.50 μM). Compounds 21 (2,3- dihydroxybenzaldehyde N-(diphenylmethylene)hydrazine) IC50 = 25.7 ± 0.003 μM, 14 (diphenylmethanone N-[1-(2,4- dihydroxy-5-nitrophenyl)ethylidene]hydrazine) IC50 = 36.6 ± 0.004 μM, 6 (3,4-dihydroxybenzaldehyde N- (diphenylmethylene)hydrazine) IC50 = 49.5 ± 0.001 μM, 13 (diphenylmethanone N-[1-(2,5-dihydroxyphenyl)ethylidene] hydrazine) IC50 = 52.6 ± 0.023 μM, and 15 (diphenylmethanone N-[1-(3,4-dihydroxyphenyl)ethylidene]hydrazine) IC50 = 57 ± 0.002 μM, showed showed much better antiglycation potential superior to the standard rutin. The compounds 7 (2,5- dihydroxybenzaldehyde N-(diphenylmethylene)hydrazine) IC50 = 66 ± 0.002 μM, and 25 (diphenylmethanone N-[1-(2,5- dihydroxyphenyl)propylidene] hydrazine) IC50 = 67.9 ± 0.001 μM showed compareably good antiglycation activity to standard rutin. All compounds were characterized by spectroscopic techniques and gave satisfactory elemental analysis.
