Application

Guaiazulene can be used as a starting material for the synthesis of:
  • Azulene-based dye molecules such as 3-(7-isopropyl-1,4-dimethylazulen-3-yl)-2-cyanoacrylic acid and 5-(7-isopropyl-1,4-dimethylazulen-3-yl)-2-cyanopenta-2,4-dienoic acid.
  • Stilbazulenyl nitrone, a second-generation azulenyl nitrone which can be used as a chain-breaking antioxidant.
  • Bis-azulenyl based near-infrared fluorescence quencher.

Radiation treatment may induce acute skin reactions. There are several methods of managing them. Validity of these methods, however, is not sufficiently studied. We therefore investigated, whether moist skin care with 3% urea lotion will reduce acute radiation skin toxicity.
