CAMPOS, ANA M et al. LAÇASSE CATALYZED-SYNTHESIS OF 4,4'-BIPHENYLDIAMINE FROM P-CHLOROANILINE. EVALUATION OF ANTIFUNGAL AND ANTIOXIDANT ACTIVITIES. J. Chil. Chem. Soc. [online]. 2016, vol.61, n.3, pp.3031-3033. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072016000300004.

Laccase is a copper-containing oxidase that catalyzes reduction of molecular oxygen to water and the oxidation of a phenolic compound. In this paper, laccase was utilized to synthesize 4,4'-Biphenyldiamine using p-chloroaniline as substrate by means of a coupling reaction. The synthesized compound, 4,4'-Biphenyldiamine, presented low antifungal activity against the phytopathogenic fungus Botrytis cinerea, however the antioxidant ability, measurement by ORAC-PGR method, was higher than substrate. This work corresponds to the first report of synthesis 4,4'-Biphenyldiamine, from p-chloroaniline in a lacasse-catalyzed reaction.

Palavras-chave : p-chloroaniline; 4,4'-Biphenyldiamine; laccase; antioxidant activity; antifungal activity.
