Antibacterial and Acetylcholinesterase Inhibitory Potentials of Triazenes Containg Sulfonamide Moiety
Pharmaceutical Chemistry Journal(2021)
Abstract
The aim of this study was to investigate the antibacterial and acetylcholinesterase (AChE) inhibitory activities of 3-(3-(2/3/4-substituted phenyl)triaz-1-en-1-yl)benzenesulfonamides (compounds 1 – 12) and to find out new possible drug candidate molecules since the available agents in clinical use have some limitations. According to the results of antibacterial screening for compounds 1 – 12, most of the synthesized compounds were found to be effective against Gram-positive microorganisms while being ineffective (MIC > 1600 μg/mL) on Gram-negative microorganisms. According to the AChE inhibition results, Ki values of compounds 1 – 12 were in the range of 5 ± 1 – 34 ± 2 nMtoward AChE. Tacrine (TAC) used as a reference drug had Ki value of 4 ± 1 nM toward AChE. The non-substituted derivative compound 1 coluld be considered as a lead compound for this study in terms of AChE inhibitory activity, since its Ki value (5 ± 1 nM) was close to that of the reference drug (TAC). Thus, compound 1 was docked at the binding site of AChE and showed good interaction with the target enzyme, suggesting their possible mechanism of action.
