RESUMO
In the present study, a new series of 1,2,3-triazole derivatives was synthesized via a click one-pot reaction. The synthesized compounds were found to be active during molecular docking studies against targeted protein 1T69 by using the Molecular Operating Environment (MOE) software. The designed and synthesized compounds were characterized by using FT-IR, 1H-NMR and LC-MS spectra. The synthesized triazole moieties were further screened for their α-amylase and α-glucosidase inhibitory activities. The preliminary activity analysis revealed that all the compounds showed good inhibition activity, ranging from moderate to high depending upon their structures and concentrations and compared to the standard drug acarbose. Both in silico and in vitro analysis indicated that the synthesized triazole molecules are potent for DM type-II. Out of all the compounds, compound K-1 showed the maximum antidiabetic activity with 87.01% and 99.17% inhibition at 800 µg/mL in the α-amylase and α-glucosidase inhibition assays, respectively. Therefore these triazoles may be further used as promising molecules for development of antidiabetic compounds.

Synthesis and characterization of novel copper complexes of metronidazole benzoate (MTZ Benz), metronidazole (MTZ) in the presence of another ligand; dichloroacetic acid (DCA) were compared and reported in the present work. Different bacterial and fungus strains were ascertained to evaluate the biological potency of the synthesized complexes, that is, Escherichia coli, Bordetella bronceptica, Staphylococcus epidermidis, Baccilus pumilus, Staphylococcus aureus and yeast strain Saccharomyces cerevisiae. Agar diffusion method was employed to investigate in vitro antibacterial activities of the synthesized metal complexes and the tested parent ligands. α-Amylase and α-glucosidase inhibition studies of the synthesized complexes were also carried out. The antibacterial potential and α-amylase and α-glucosidase inhibition studies of complexes were further investigated by molecular docking studies, which supported the experimental results. Significant α-amylase and α-glucosidase inhibition activities were shown by the synthesized complexes. S-1 and S-5 were found to be most inhibitors of α-amylase and α-glucosidase having IC50 42.50, 44.80 and 4.52 µg/mL, 4.80 µg/mL, respectively. The newly synthesized copper complexes showed overall better biological activities compared to each parent ligands used.Communicated by Ramaswamy H. Sarma.
