A series of substitute pyrazole compounds including azide, acetyl,
triazole, morpholine, piperidine, and pyrrolidine moieties were
synthesized and their structures were elucidated by NMR, HPLC and mass
spectroscopy. The inhibition efficiencies of all novel compounds against
acetylcholinesterase (AChE) and glutathione S-transferase (GST) enzymes
were investigated. In vitro studies revealed that the inhibitory activities of substitute pyrazole compounds were determined with Ki
values in the range of 0.11–0.49 µM for AChE, and 0.12–0.91 µM for GST,
respectively. Furthermore, the molecular docking studies of the
detailed interactions between the pyrazole compounds and AChE-GST
enzymes were identified with bonding type, distance, hydrophobic bonds
and hydrogen bonds. The binding energies of the AChE-pyrazole analogs’
complexes were found between –5.5 and –9.3 kcal/mol, and the binding
energies of the GST-pyrazole analogs’ complexes were found between –5.9
and –9.2 kcal/mol.
