Kinetic studies of the interaction of cannabinoids with singlet oxygen. [PDF]
Photochem PhotobiolGraphical abstract showing sensitization of singlet oxygen by xanthone and its subsequent quenching by cannabinoids. Abstract The kinetics of the interaction of several cannabinoids with singlet oxygen have been examined in acetonitrile solution using laser flash photolysis techniques and using xanthone as a singlet oxygen sensitizer.

Ultrafast Intersystem Crossing in Xanthone from Wavepacket Dynamics.
Journal of the American Chemical Society, 2021 Most aromatic ketones containing first-row elements undergo unexpectedly fast intersystem crossing in a few tens of picoseconds and a quantum yield close to unity. Among them, xanthone (9H-xanthen-9-one) possesses one of the fastest singlet-triplet rates

Mangiferin‐Encapsulated Lipid Carriers: Innovative strategy for Enhanced Brain Delivery in Alzheimer's Therapy [PDF]
Alzheimers DementAbstract Background Alzheimer's disease (AD) is a neurodegenerative disease involving amyloid‐β plaques and tau tangles leading to cognitive impairment. Mangiferin (MGF), a xanthone with neuroprotective activity, has low bioavailability. Lipid nanoparticles enhance brain targeting and solubility of MGF.
