New cyclotriphosphazenes with butylated oxyanisole motif; synthesis, characterization and biological properties

Abstract

In the present work, new cyclotriphosphazene derivatives containing butylated oxyanisole (BA) group (3, 4a/b, 6a/b, 7, 11a/b and 12) were synthesized and characterized with using elemental analysis, mass, and NMR (1H and 31P) spectroscopic techniques in detailed. The molecular and crystal structure of compound 3 was also determined by single-crystal X-ray crystallography. The antimicrobial activities of the compounds (3, 7 and 12) were evaluated against strains of Staphylococcus aureus ATCC 29213 as Gram positive cocci, Bacillus cereus DSMZ 4312 as Gram positive bacilli, Escherichia coli ATCC 8739 as Gram negative bacilli, and Candida albicans ATCC 10231, a dimorphic yeast species representing fungi as well as antioxidant activities of these compounds. In the biological and antioxidant activity tests carried out, compound 3 stood out with both antibacterial and antioxidant activity compared to other compounds.
