A New Method for the Synthesis of New Derivatives of “1,3- diaryl-2-n-azaphenalene and n-acyl-1,3-diaryl-2-N-azephenylene” by Using Nano catalyst and Analyzing Antibacterial Activity of Structures

Abstract

In this research, synthesized well derivatives of 1,3-diaryl-2-N-azaphenalene and N-acyl-1.3-diaryl-2-N- azaphenalene as a macromolecule in the presence of nanoparticles (Fe3O4 coated with L-Arginine)as a magnetic Nano catalyst in a one-pot reaction of compounds 7.2-Naphthalene diol, aldehydes,ammonium derivatives (ammonium acetate or ammonium hydro phosphates) and solvent (waterand alcohol) with high yield and short reaction times, economical and simple workup. In this study,apart from the innovation in the synthesis of a macromolecule, the antibacterial activity of thesecompounds was evaluated for the first time. The reaction was doe under very moderate conditionsat room temperature. The chemical structures of all synthesized compounds were determined usinginfrared, 1H NMR and 13C NMR spectroscopies. After the production of nanoparticles, the structure ofthe obtained nanoparticles was characterized via Fourier transform infrared spectroscopy (IR) and fieldemission scanning electron microscopy (FE-SEM). The results demonstrated that the average size ofthe synthesized magnetite nanoparticles is about 21 nm. The heterogeneous catalyst used was easilyseparated magnetically and reused without any significant loss of catalytic activity and magnetism.Eventually, antibacterial activity of the synthesized compounds was investigated by Escherichia coli(ATCC: 25922) and Pseudomonas aeruginosa (ATCC: 27853) as gram negative bacteria, Staphylococcusepidermidis (ATCC: 14990) and Staphylococcus aureus (ATCC: 29213) as gram positive bacteria. Someof these products exhibit significant antibacterial activity.
