Descripción general

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.

Aplicación

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

Apatone™, a combination of menadione (2-methyl-1,4-naphthoquinone, VK3) and ascorbic acid (vitamin C, VC) is a new strategy for cancer treatment. Part of its effect on tumor cells is related to the cellular pro-oxidative imbalance provoked by the generation of hydrogen

The CAN-catalyzed three-component between reaction between primary amines, beta-dicarbonyl compounds and naphthoquinones or 2-bromonaphthoquinones afforded, respectively, 5-hydroxybenzo[g]indoles and benzo[f]indole-4,9-diones, the former of which were transformed into tetracyclic azepino[1,2-a]benzo[g]indole systems through a gamma-alkylation/ring-closing metathesis sequence.

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
