Synthesis of some new 1,2,4-triazole derivatives, investigation of their fluorescence properties and biological activities
Abstract
In this work, new heterocyclic compounds containing
1,2,4-triazole ring were synthesized
starting from iminoester hydrochlorides and benzhydrazide. The fluorescence
properties of the novel triazole compounds synthesized were determined in
organic solvents such as methanol and DMSO. The diimine derivatives among the
new triazoles show high fluorescence intensities in methanol. Reduced diimines
(8) have lower fluorescence
properties in methanol than diimine compounds (6). The compounds were also tested for their antioxidant and
carbonic anhydrase inhibitory (CAI) activities. Low CAI activity was observed.
Bis Schiff bases (6) showed better
activity with lower IC50 values of 200 and 330 μM. The compounds
showed moderate to high antioxidant activity in both DPPH and FRAP antioxidant
tests. The SC50 values in DPPH test were as low as 0.01 mg/mL, close
to that of standard antioxidants. Similarly, a high TEAC value as 8197 mM was
observed showing considerably high FRAP activity. Structural differences were
effective on the antioxidant activities of the new compounds. Benzoylhydrazones
(2), oxadiazoles (3) and amino-triazoles (4) showed higher activity in both
antioxidant tests as compared to compounds 5-8.
