ABSTRACT
Diabetes mellitus (DM) is a chronic disorder and still a challenge throughout the world, and therefore the search for safe and effective inhibitors for α-amylase and α-glucosidase is increasing day by day. In this work, we try to carry out the synthesis, modification, and computer-aided results of and biological research on thiadiazole-based Schiff base derivatives and evaluate their in vitro α-amylase and α-glucosidase inhibitory potential (1-15). In the current series, all of the synthesized analogues were shown to have potential inhibitory effects on targeted enzymes. The IC50 values for α-amylase values ranged from 20.10 ± 0.40 to 0.80 ± 0.05 µM, compared with the standard drug acarbose having an IC50 value of 10.30 ± 0.20 µM, while for α-glucosidase, the IC50 values ranged from 20.10 ± 0.50 to 1.20 ± 0.10 µM, compared to acarbose with an IC50 value of 9.80 ± 0.20 µM. For better understanding, a SAR investigation was undertaken. In this series, nine scaffolds (1, 2, 3, 6, 9, 10, 11, 13, and 15) were more active than the reference drug and the docking parameter RMSD values for α-glucosidase and α-amylase were 1.766, 2.7746, 1.6025, 2.2112, 3.5860, 2.3360, 1.6178, 2.0254, and 2.0797 and 2.6020, 1.9509, 3.1642, 1.7547, 2.2130, 1.4221, and 1.1087, respectively. The toxicity of the selected analogues was calculated by using the OSIRIS tool, and the TPSA values were found to be lower than 140 to represent the drug-like properties; those from Molinspiration were studied as well. The following properties were studied and found to have better biological properties. The remaining analogues (4, 5, 7, 8, 12, and 14) were also identified as potential inhibitors of both enzymes, but they were less active than the reference due to the substituents attached to the aromatic parts. The structures of synthesized compounds were confirmed through different spectroscopic analyses.
