Synthesis, Structure Elucidation and Antibacterial Activity of Ni(II)-2-Acetoxybenzoic Acid Complex

Abstract

2-acetoxybenzoic acid, also known as aspirin, is one of the most widespread and important pharmaceutical compound used in the treatment of pain, inflammation, and febrile conditions. In addition to its well-known therapeutic properties, 2-acetoxybenzoic acid is increasingly being investigated in the context of its interactions with metals, leading to new insights into potential applications in medicine, chemistry, and biotechnology. Among the metals that form complex compounds with 2-acetoxybenzoic acid, nickel is one of the most interesting due to its specific electrochemical properties and biological activity. The study of the 2-acetoxybenzoic acid-nickel complex plays a significant role in understanding the molecular mechanisms of interaction between drugs and metal ions, as well as the potential therapeutic benefits of these compounds. This research thoroughly examines the structural, chemical, and biological aspects of the 2-acetoxybenzoic acid-nickel complex, with particular emphasis on its potential application in the pharmaceutical industry and medicine. The structure of this complex was determined by various spectroscopic and analytical techniques, including Fourier transform infrared spectroscopy (FTIR), ultraviolet-visible spectroscopy (UV), mass spectrometry (MS), melting point methods, and optical microscopy. These methods contributed to the understanding of the interaction mechanisms between the ligand and the nickel ion center, opening the possibility for further investigation of the pharmacological properties and potential therapeutic applications of this complex. The antibacterial and antifungal activity of the synthesized Ni(II) complex with 2-acetoxybenzoic acid was investigated, and it was found that the metal complex exhibits varying degrees of inhibitory effects on bacteria.
