Photoprotection from harmful ultraviolet (UV) radiation exposure is a key problem in modern society. Mycosporine-like amino acids found in fungi, cyanobacteria, macroalgae, phytoplankton, and animals are already presenting a promising form of natural photoprotection in sunscreen formulations. Using time-resolved transient electronic absorption spectroscopy and guided by complementary ab initio calculations, we help to unravel how the core structures of these molecules perform under UV irradiation. Through such detailed insight into the relaxation mechanisms of these ubiquitous molecules, we hope to inspire new thinking in developing next-generation photoprotective molecules.

揭示霉菌素氨基酸基序的光保护特性

免受有害的紫外线(UV)辐射的光保护是现代社会中的一个关键问题。在真菌,蓝细菌,大型藻类,浮游植物和动物中发现的类霉菌素样氨基酸已经在防晒配方中呈现出一种有希望的天然光保护形式。使用时间分辨的瞬态电子吸收光谱法,并辅以从头算起的计算,我们有助于揭示这些分子的核心结构在紫外线照射下的性能。通过对这些无处不在的分子的松弛机理的如此详尽的洞察,我们希望激发开发下一代光保护分子的新思路。
