Ring buckling and C=N isomerization pathways for efficient photoprotection in two nature‐inspired UVA sunscreens revealed through ultrafast dynamics and high‐level calculations

Photochemistry and Photobiology, Volume 100, Issue 2, Page 298-313, March/April 2024.
The UV filters in sunscreens are our frontline defense against the harms of ultraviolet radiation. In this paper, we continue the industry's shift toward nature‐inspired, particularly microbial, UV filters by unraveling the fundamental mechanisms of photoprotection in two synthetic analogs of mycosporine‐like amino acids.

Biosynthetic Mechanism for Sunscreens of the Biocontrol Agent Lysobacter enzymogenes

PLoS ONE, 2013
Lysobacter are ubiquitous environmental bacteria emerging as novel biocontrol agents and new sources of anti-infectives. So far, very little effort has been invested in the study of the biology of these Gram-negative gliding bacteria. Many Lysobacter species are characterized by their yellow-orange appearance.
