Tumor anti-initiating activity of some novel 3, 4-dihydropyrimidinones [PDF]

Pharmacological Reports, 2009
Halting the tumor initiation process by targeting the inhibition of the carcinogens metabolic activators (CYP), the induction of the carcinogen detoxification enzymes (glutathione-S-transferases, GSTs), and the induction of antioxidant activity is an effective strategy.

Self‐Healing Hydrogel Dressing with Solubilized Flavonoids for Whole Layer Regeneration of Diabetic Wound

Advanced Healthcare Materials, Volume 14, Issue 11, April 25, 2025.
High glucose‐ and acid‐responsive hydrogel with dynamic covalent bond solubilized with flavonoids (Gel‐Flavonoids) is designed for diabetic wound healing. The Gel‐Flavonoids adapt to irregular wound shapes and release antioxidants in high‐glucose environments, effectively reducing reactive oxygen species.
