Sumrra, Sajjad Hussain published the artcileComputational investigation of molecular structures, spectroscopic properties, cholinesterase inhibition and antibacterial activities of triazole Schiff bases endowed metal chelates, SDS of cas: 1455-77-2, the main research area is triazoldiamine salicylaldehyde derivative electronic structure antibacterial enzyme inhibition activity; transition metal triazole Schiff base preparation antibacterial enzyme inhibition.
The aim of this project was to introduce novel bioactive compounds through the design and synthesis of two mono-Schiff bases, 4- [(5-amino-1H-1,2,4-triazol-3-yl)imino]methylbenzene-1,3-diol (L1) and 2-[(5-amino-1H-1,2,4-triazol-3-yl)imino]methyl-6-methoxyphenol (L2) and one bis-Schiff base, 2,2′-{1H-1,2,4-triazole-3,5-diylbis[nitrilomethylylidene]}bis(6-methoxyphenol) (L3) together with their complexes of transition metals [VO(IV), Cr(III), Mn(II), Fe(II), Co(II), Ni(II), Cu(II), and Zn(II)]. The mol. structures of as-synthesized Schiff bases were explicitly confirmed by phys., spectral, anal. and computational studies. Quantum chem. calculations based on d. functional theory (DFT) were performed at B3LYP/6-311+G(d.p) level to explore the optimized geometrical structures, mol. electrostatic potential (MEP), Mulliken at. charges (MAC) and frontier MO (FMO) anal. of the as-synthesized ligands. The FMO energy gaps were rationalized to be 0.162, 0.158 and 0.138 eV for ligands (L1), (L2) and (L3), resp. which can efficiently polarize their chem. structures. As-synthesized metal complexes have good agreement with their purposed structures with octahedral geometry except V complexes, which have square pyramidal geometry. As-synthesized compounds were also evaluated through TG and fluorescence anal. Addnl., the compounds were also scrutinized for antibacterial activity against five bacterial strains (Halomonas halophila, Chromohalobacter israelensis, Escherichia coli, Chromohalobacter salexigens and Halomonas salina) and enzyme inhibition bioassay against butyrylcholinesterase (BChE) and acetylcholinesterase (AChE). The complexes (15) and (1) were the most active inhibitors of BChE and AChE enzymes with 94.60% and 90.90% activity, resp. Also, all the compounds also exhibited significant antibacterial activity. The metal complexes displayed more biol. activity in contrary to parent ligands as a result of chelation.
