Therapeutic effect of NEO400, perillyl alcohol conjugated to linoleic acid, in a mouse model of UV‐induced skin damage

Photochemistry and Photobiology, Volume 101, Issue 2, Page 338-349, March/April 2025.
In the present work with mouse models, we demonstrate that a novel compound, NEO400, is able to profoundly protect skin against damage caused by UV radiation (UVR) when it is applied to skin post‐UVR exposure. In comparison, Aloe vera or linoleic acid are unable to achieve a similar level of protection.

Interventional human ocular safety experiments for 222‐nm far‐ultraviolet‐C lamp irradiation

Photochemistry and Photobiology, Volume 101, Issue 2, Page 517-526, March/April 2025.
To directly assess the ocular safety of 222‐nm far‐ultraviolet‐C (UVC) irradiation in humans, five subjects were exposed to 222‐nm UVC at doses of 22, 50, and 75 mJ/cm2. The findings indicate that far‐UVC irradiation does not cause “clinically significant photokeratitis” or long‐term ocular damage, though it may induce temporary discomfort.

Investigation of 222‐nm ultraviolet C irradiation bactericidal effect on the surgical field in a rabbit model

Photochemistry and Photobiology, EarlyView.
In a rabbit surgical field model seeded with polymicrobial flora, a single dose of 222‐nm UV‐C (500 mJ/cm2) markedly reduced bacterial colonies, achieving a bactericidal effect comparable to 254‐nm UV‐C (200 mJ/cm2), while no UV‐C irradiation showed heavy growth. Wound healing did not differ among groups. Microbiota profiling detected SSI‐relevant taxa

RAD51 and RAD51 paralog inhibition sensitizes nonreplicating quiescent keratinocytes to UV radiation

Photochemistry and Photobiology, EarlyView.
UV radiation and other compounds generate DNA adducts that block transcription and induce cell death if not removed by the nucleotide excision repair system. In this work, we used a small‐scale pharmacological screen to discover that inhibition of the recombinase RAD51 sensitized nonreplicating quiescent keratinocytes to both UVR and other agents that ...

Photoprotective potential of gadusol against ultraviolet B radiation in melanocytes

Photochemistry and Photobiology, EarlyView.
Gadusol protects melanocytes from ultraviolet B (UVB)‐induced damage without cytotoxicity. Abstract The increasing incidence of skin cancer, including melanoma, combined with the need for ultraviolet (UV) filters that are safe for human health and marine ecosystems, is driving the search for new photoprotective agents.
