Mechanistic Insights Into the Photosensitizing Properties of the Topical Retinoid Tazarotene

ChemMedChem, Volume 21, Issue 8, 28 April 2026.
Light‐activated retinoids: Tazarotene and its active metabolite tazarotenic acid form long‐lived triplet excited states upon UVA irradiation, generating singlet oxygen and promoting photochemical reactions. These processes correlate with reduced fibroblast viability under light exposure, revealing potential phototoxicity and implications for combined ...

Cytotoxic polyprenylated xanthones from the resin of Garcinia hanburyi

, 2006
Thirteen xanthones (1-13) were isolated from the resin of Garcinia hanburyi. Among them, two new compounds (namely gaudichaudic acid, and isogambogenic acid, 1, 2), and one new natural product (deoxygaudichaudione A, 3) were identified on the basis of ...

Ligand architecture and secondary‐sphere effects in a well‐defined cobalt(IV)–oxo complex

Bulletin of the Korean Chemical Society, Volume 47, Issue 4, Page 484-492, April 2026.
A well‐defined cobalt(IV)–oxo complex supported by a neutral tetraazamacrocyclic ligand is generated and fully characterized. The cobalt(IV)–oxo species exhibits electrophilic oxygen‐atom and hydrogen‐atom transfer reactivity, strongly modulated by protonation and secondary coordination sphere effects, providing new insight into structure–reactivity ...
