Yeni Piridin Bazlı N-Açil Hidrazon Türevlerinin Sentezi ve Spektroskopik Karakterizasyonu ve Glukozamin-6-Fosfat Üzerine Moleküler Yerleştirme Çalışmaları

Abstract

Antimicrobial resistance in infectious diseases caused by organisms such as bacteria, fungi, viruses, and parasites has led to an increase in studies and demands for new antimicrobial drug development. The compounds including pyridine and N-acylhydrazone skeletons in their structures have a large application area in drug discovery due to their anticancer, anti-tubercular, anti-bacterial and anti-fungal activities. Here, the novel N-acyl-hydrazone derivatives, (E)-2-oxo-N'-(2,3,4-trimethoxybenzylidene)-1,2-dihydropyridine-3-carbohydrazide and (E)-N'-(1-(4-bromophenyl) ethylidene)-2-oxo-1,2-dihydropyridine-3-carbohydrazide were synthesized through a multistep reaction sequence. The structures of newly synthesized compounds were established on the basis of IR, 1D and 2D NMR spectra and mass spectral data. The theoretical electronic structure analysis was performed by density functional theory (DFT) at the B3LYP level with the 6-311++G(d,p) basis set in the gas phase of synthesized compounds. The newly synthesized compounds were docked on glucosamine-6 phosphate synthase to determine potential interactions between the analyzed compounds and its active site due to its role in microbial cell wall synthesis. The possibilities of these compounds to being active for antimycobacterial and antituberculosis have been found as quite high, and their interactions in the binding site have been determined with the range of binding affinity, [-7.1, -7.3] kcal/mol, respectively.
