Synthesis, characterization and biological relevance of some metal (II) complexes with oxygen, nitrogen and oxygen (ONO) donor Schiff base ligand derived from thiazole and 2-hydroxy-1-naphthaldehyde

Synthesis, characterization, mass spectral fragmentation, thermal study and biological evaluation of new Schiff base ligand and its metal(II) complexes derived from 4-(diethylamino)salicylaldehyde and thiazole moiety

“…This activity found to be improved on coordination of the hetero atoms of the L with various metal ions. This enhancement in the antimicrobial activity of the complexes over the free ligand can be explained on the basis of chelation theory [36,37]. It is known that chelation enhances the ligand to act as more powerful and potent bactericidal/fungicidal agents by inhibiting the growth of bacteria/fungi, thus a zone of inhibition of metal complexes was found to be higher compared to the ligand [23].…”

Schiff Bases Derived from 2-Hydroxynaphthalene-1-carbaldehyde and their Metal Complexes

“…The in vitro cytotoxicity behaviour against Artemia salina carried out. The ligand displayed more in vitro antioxidant potential than its metal complexes [81]. In recent years, more interest is shown with the synthesis of novel biologically active compounds.…”

Solid Phase Extraction of Trace Al(III), Fe(II), Co(II), Cu(II), Cd(II) and Pb(II) Ions in Beverages on Functionalized Polymer Microspheres Prior to Flame Atomic Absorption Spectrometric Determinations

“…21,[34][35][36][37][38][39] N and S donor centers in the thiazole ring exhibit excellent sorption selectivity for some metal ions including divalent transition metal ions and noble metals because of their strong affinity to form complexes with these types of metal ions, and also thiazoles show interesting physicochemical properties and remarkable biological and pharmacological activities, and have applications in different fields. [40][41][42][43][44][45] This study focuses on the effectiveness of 2-aminobenzothiazole (ABTAL) functionalized polymeric microspheres consisting of poly(glycidyl methacrylate-methyl methacrylate-divinylbenzene), poly(GMA-MMA-DVB) used as solid phase adsorbent for selective preconcentration/separation and sensitive determination of Al(III), Fe(II), Co(II), Cu(II), Cd(II) and Pb(II) ions in different beverages by using flame atomic absorption spectrometry (FAAS). For this purpose, crosslinked porous GMA-MMA-DVB terpolymer was synthesized in the form of microsphere by suspension polymerization, and then functionalized with ABTAL via ring opening reactions of epoxide groups belonging to GMA.…”
