| An ester formed by the condensation of gallic acid and propanol. Propyl gallate (PG), chemically known as propyl-3,4,5-trihydroxybenzoate, is widely present in processed food and cosmetics, hair products, and lubricants. PG alone demonstrated antioxidative and cytoprotective properties against cellular damage and gained a pro-oxidative property in combination with copper (II). It was reported that PG was one of the most active compounds capable of generating H2O2 in DMEM media Main cancer-relevant pathways modulated by propyl gallate A. Redox imbalance & oxidative stress (dominant) -↑ Intracellular ROS (context- and dose-dependent) -Pro-oxidant in cancer cells with high basal ROS -Mitochondrial superoxide accumulation -Thiol depletion (↓ GSH, ↓ Trx buffering capacity) Importance: ★★★★★ (Primary mechanism) B. Mitochondrial dysfunction & intrinsic apoptosis -↑ MOMP → caspase cascade -Loss of mitochondrial membrane potential (ΔΨm) -Cytochrome-c release -Caspase-9 → caspase-3 activation -↑ Bax / ↓ Bcl-2 ratio Importance: ★★★★☆ C. ER stress & unfolded protein response (UPR) -↑ PERK–eIF2α–ATF4–CHOP -ROS-linked protein misfolding -Pro-apoptotic UPR signaling dominates over adaptive UPR Importance: ★★★☆☆ D. Cell cycle disruption -G1 or G2/M arrest (cell-type dependent) -↓ Cyclin D1, Cyclin B1 -↑ p21, p27 Importance: ★★☆☆☆ E. MAPK stress signaling -↑ JNK / p38 -Stress-activated apoptosis signaling -Often precedes mitochondrial failure Importance: ★★☆☆☆ F. Inflammation & survival pathways (secondary) -↓ NF-κB, ↓ STAT3 (indirect) -Suppression is largely ROS-mediated, not direct inhibition -Reduced anti-apoptotic gene transcription Importance: ★★☆☆☆ G. NRF2–ARE signaling (dual role) -Low dose: NRF2 activation → cytoprotection -High dose / cancer cells: NRF2 overwhelmed → apoptosis Importance: ★★☆☆☆ (Highly context dependent; double-edged)

| The selectivity of cancer products (such as chemotherapeutic agents, targeted therapies, immunotherapies, and novel cancer drugs) refers to their ability to affect cancer cells preferentially over normal, healthy cells. High selectivity is important because it can lead to better patient outcomes by reducing side effects and minimizing damage to normal tissues. Achieving high selectivity in cancer treatment is crucial for improving patient outcomes. It relies on pinpointing molecular differences between cancerous and normal cells, designing drugs or delivery systems that exploit these differences, and overcoming intrinsic challenges like tumor heterogeneity and resistance Factors that affect selectivity: 1. Ability of Cancer cells to preferentially absorb a product/drug -EPR-enhanced permeability and retention of cancer cells -nanoparticle formations/carriers may target cancer cells over normal cells -Liposomal formations. Also negatively/positively charged affects absorbtion 2. Product/drug effect may be different for normal vs cancer cells - hypoxia - transition metal content levels (iron/copper) change probability of fenton reaction. - pH levels - antiOxidant levels and defense levels 3.
