General description

2-Bromo-1,4-naphthoquinone (BrQ) is a 1,4-naphthoquinone derivative that can be prepared by the bromination of 1-naphthol using N-bromosuccinimide. Its efficacy as an antifeedant against the cabbage looper, Trichoplusia ni has been evaluated.2 The reaction of BrQ with xanthene under photochemical conditions has been investigated. A report suggests that the replacement of 2-methyl-1,4-naphthoquinone with BrQ enhances its ability to produce hydrogen peroxide which can be employed for cancer treatment.

Application

2-Bromo-1,4-naphthoquinone may be used in the preparation of:
  • benzo[f]indolequinones
  • 2-azido-1,4-naphthoquinone
  • 2-allyl-3-bromo-1,4-naphthoquinone
  • 2-(3-indolyl)-1,4-naphthoquinones

Continuing our screening program for novel anti-parasite compounds, we synthesized seven 1,4-naphthoquinones coupled to 1,2,3-triazoles, five nor-β-lapachone-based 1,2,3-triazoles and ten α-lapachone-based 1,2,3-triazoles. These and other naphthoquinonoid compounds were evaluated for their activity against promastigote forms of antimony-sensitive and -resistant strains
