LARIZA ANDRADE-GUEL, Marlene; LOPEZ-LOPEZ, Lluvia Itzel  e  SAENZ-GALINDO, Aidé. Synthesis, IR characterization and preliminary antibacterial evaluation of 2-(amine)-l,4-naphthoquinone derivatives. TIP [online]. 2011, vol.14, n.2, pp.75-82. ISSN 1405-888X.

Naphthoquinones are compounds of natural or synthetic origin which have shown important biological activities, as antibacterial, antifungal, antimalarial and anticancer agents. This paper reports the 2-(amine)-1,4-naphthoquinone synthesis using different methods such as the room temperature synthesis (RTS), conventional heating synthesis (CCS) and ultrasound-assisted synthesis (UAS). Characterization was performed by infrared spectroscopy. in addition, antibacterial capacity was also determined against proteus sp. and Enterococcus faecalis strains. The 2-benzylamine-1,4-naphthoquinone derivative showed the highest activity.

Palavras-chave : 1,4-naphthoquinone; antibacterial agent; ultrasound.
