Assaying Antioxidant and Antimicrobial Activities of 1-phenyl-3-naphthoic acid Derivatives

Laboratory synthesized 1-phenyl naphthoic acid systems (substituted naphthalenes or lignans) were evaluated for their antioxidant and antimicrobial potential. All the phenyl naphthoic acids showed significant to moderate antioxidant activity in DPPH (2, 2-diphenyl- 1-picrylhydrazyl) and FeCl3 (ferric chloride) assay.

All the lignan compounds exhibited significant to moderate antimicrobial and antifungal activity except one of the compounds which showed no toxicity to the fungal species.
