Gamma-tocopherol (γ-tocopherol), a major isoform of vitamin E, exhibits potent antioxidant, anti-inflammatory, and anticancer properties, making it promising therapeutic candidate for treating oxidative stress-related diseases. Unlike other tocopherol isoforms, γ-tocopherol effectively neutralizes reactive oxygen species (ROS) nitrogen (RNS), providing robust cellular protection against damage lipid peroxidation. Its anti-inflammatory effects are mediated through the modulation pathways involving cyclooxygenase-2 (COX-2) tumor necrosis factor-alpha (TNF-α), reducing chronic inflammation its associated risks. In cancer therapy, demonstrates multifaceted activity, including inhibition growth, induction apoptosis, suppression angiogenesis, with significant efficacy observed in cancers such as prostate, lung, colon. Preclinical clinical studies support mitigating stress, inflammation, progression, excellent tolerance at physiological levels. However, high doses necessitate careful evaluation to minimize adverse effects. This review consolidates current knowledge on γ-tocopherol’s biological activities implications, underscoring importance natural compound managing cancer.

The transcription factor erythroid 2-related 2 (Nrf2) is a central regulator of cellular defense mechanisms against oxidative stress and inflammation. Keap1 (Kelch-like ECH-associated protein 1) regulates Nrf2 activity by ubiquitination-mediated cytoplasmic retention, thereby suppressing its nuclear translocation subsequent transcriptional activation genes encoding phase II detoxifying enzymes. Using structure-based virtual screening approach, we screened ~16,000 natural compounds to identify Keap1-Nrf2 PPI inhibitors. Nine were identified based on their high binding affinities favorable interactions with Keap1, primarily through non-covalent interactions. To validate the stability these inhibitors, molecular dynamics (MD) simulations performed, confirming robustness Keap1-inhibitor complexes over time. Subsequent in vitro assays human epithelial keratinocyte cells (HaCaT) revealed that six notably upregulated mRNA expression, regis tering increases from 23% 50% comparison control. Notably, chebulinic acid emerged as most potent compound, demonstrating greatest elevation expression. Penetration studies further showed acid, when encapsulated silk fibroin, achieved 0.14% penetration rate after 24 h though it could not penetrate into stratum corneum alone. This result highlighted potential use anti-aging skincare formulations. Collectively, our findings affirmed docking reliable effective approach for identification novel agents targeting pathway.
