Hybrid Pyrazole‐Tetrazole Derivatives with High α‐Amylase Inhibition Activity: Synthesis, Biological Evaluation and Docking Study.

The elaboration of some N‐alkylated pyrazole‐tetrazole derivatives is reported. The structures of the newly ones are verified using NMR and FTIR spectroscopies, mass spectrometry as well as elemental analysis. Their potencies to inhibit the α‐amylase enzyme were evaluated using spectrophotometric method and the obtained results showed that some of them were extremely potent with respect to the used positive control. The structure activity relationship showed that the α‐amylase inhibition activity depends on the alkylation position as well as the nature of the alkyl moiety and the alkylation at the N1 position with a donor group improves the α‐amylase inhibition activity. Docking study was also performed and the obtained results support the experimental results in the case of the alkylation position effect. These findings suggest that the molecules reported in this study may be used as good drug candidate to treat Type 2 diabetes. [ABSTRACT FROM AUTHOR]
