2,3-Dihydroxybenzoic acid was used to study the complexes of manganese with aliphatic and aromatic polyhydroxy ligands in basic media by electrochemical, spectrophotometric and magnetic methods. It was used in isolation of new siderophore named vulnibactin from low iron cultures of Vibrio vulnificus, a human pathogen. It was used as cocrystal former to study the influence of position isomerism on the co-crystals formation and physicochemical properties of piracetam.

During infection, the fungal pathogen Aspergillus fumigatus forms biofilms that enhance its resistance to antimicrobials and host defenses. An integral component of the biofilm matrix is galactosaminogalactan (GAG), a cationic polymer of α-1,4-linked galactose and partially deacetylated N-acetylgalactosamine (GalNAc). Recent

A new siderophore named vulnibactin has been isolated from low iron cultures of Vibrio vulnificus, a human pathogen. The structure was established as N-[3-(2,3-dihydroxybenzamido)propyl]-1,3-bis[2-(2-hydroxy-phenyl)- trans-5 - methyl-2-oxazoline-4-carboxamido]propane by a combination of acid hydrolysis, nuclear magnetic resonance spectroscopy and positive fast
