2. 1. The cyanobacterial pigments scytonemin and nostodione A - Synthesis, photophysicochemical behavior and biological studies

   Author : Andreas Ekebergh; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; UV-screeners; design of experiments; cascade reactions; palladium catalysis; nostodione A; ligand effect; gold catalysis; kinase inhibitor; Scytonemin; photo-stability;

   Abstract : The natural UV-screener scytonemin is found in a plethora of cyanobacterial species. Its UV-protective ability allows the bacteria to thrive in inhospitable locations exposed to intense solar radiation. Scytonemin has a dimeric structure consisting of two 1-1' linked 3-(4-hydroxybenzylidene)cyclopenta[b]indole-2-one moieties. READ MORE

4. 2. Chemical and Dermatological Aspects of UV-absorbing Compounds

   Author : Isabella Karlsson; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Contact Allergy; Photoallergy; Dibenzoylmethane; Octocrylene; Ketoprofen; Scytonemin;

   Abstract : ABSTRACT The sun’s UV radiation is necessary for the existence of life on earth. However, too much UV exposure can lead to the development of skin cancer. Therefore, sunscreens are often used by the general population as protection from excessive UV radiation. READ MORE
