“…On the other hand, amino acid Schiff bases and their first-row transition metal complexes exhibit fungicidal, bactericidal, antiviral, and antitubercular activity [13][14][15][16][17]. Furthermore, oxovanadium complexes, especially with phenanthroline ligands, exhibit potent antitumor activity [18,19], DNA binding and DNA-photocleavage activities [20][21][22][23][24].In our previous work, we have synthesized and structurally characterized some oxovanadium complexes with multidentate Schiff base ligand and 1, 10-phenanthroline [25][26][27][28][29][30]. To continue our research in this project, we designed a new aminophenol-based multifunctional Schiff base ligand K 2 HL 1 (K 2 HL 1 = potassium 2-(((2-hydroxynaphthalen-1-yl)methylene)amino)pentanedioate) to construct potential oxovanadium-based material and drug.…”
