摘要: The present application relates to novel compounds able to absorb UV radiation and comprise antimicrobial properties as well. The compounds herein described are novel and undisclosed scytonemin analogs, able to absorb up to 90% of UV-A radiation and can cover a broader UV to blue light absorption range from 293 nm to 500 nm. When mixtures of more than one compound are used, their synergetic absorption properties can cover an even broader spectrum within 293 nm to 500 nm. The compounds described present faint coloration, and some are even colorless, therefor the present compounds can be easily incorporated in formulations to be used in cosmetic products, sunscreens or lenses for sunglasses.
