AI finds plant compound mix that fights sun-damaged skin cells

Medicinal Plants
The four o'clock flower blooming in your evening garden, along with the quercetin found in onions, apples, and capers, just got new scientific backing as a defense against UV skin damage, giving home gardeners another reason to value the plants they're already growing.
Researchers wanted to find natural substances that could protect skin from sun damage by keeping cell 'power plants' called mitochondria healthy. They used artificial intelligence to test a bunch of compounds, including quercetin (found in many fruits and vegetables), spermidine, and an extract from the four o'clock flower, and found that combining several of them worked better than any single compound alone. The best mix reduced aging signs and even helped tail regeneration in sun-damaged zebrafish and mice, hinting it could someday show up in sunscreens or anti-aging skincare.
Key Findings
AI-assisted high-content screening identified quercetin, spermidine, adenosine, Vitamin K2, and Mirabilis jalapa extract as mitochondria-protective compounds against UVB damage
The optimized combination CC-2 restored ATP production and mitochondrial morphology, reduced cell senescence markers, and upregulated COLLAGEN I, LAMIN B1, and SIRT3 in UVB-exposed human skin cells
CC-2 improved fin regeneration in UVB-exposed zebrafish and showed superior anti-photoaging effects in mice compared to the other combination tested

Scientists used AI to screen natural compounds and found that a combination including quercetin, spermidine, and an extract from the four o'clock flower protects skin cells from sun damage by repairing damaged mitochondria, the cell's energy factories. The best blend reduced signs of aging in sun-exposed mouse and zebrafish skin, suggesting a future cosmetic ingredient rooted in plant chemistry.

Original paper
Deep learning of multiplexed mitochondrial morphology identified natural compound combinations against skin photoaging.
Skin photoaging is primarily driven by mitochondrial dysfunction. Although natural products have demonstrated protective effects against Ultraviolet (UV)-induced damage, efficient screening strateg...

Gene editing removes 97% of celiac-triggering proteins from bread wheat
It could mean that people with celiac disease — roughly 1 in 100 worldwide — may one day safely eat bread made from real wheat, without sacrificing the taste...
Mirabilis jalapa, the marvel of Peru or four o'clock flower, is the most commonly grown ornamental species of Mirabilis plant, and is available in a range of colors. Mirabilis in Latin means wonderful and Jalapa is the state capital of Veracruz in Mexico. Mirabilis jalapa is believed to have been...
