RosA, Rosmarinic acid: Click to Expand ⟱
Features: polyphenol
Polyphenol of many herbs - rosemary, perilla, sage mint and basil. Rosmarinic acid (RA) is predominantly found in a variety of medicinal and culinary herbs, especially those belonging to the Lamiaceae family, including rosemary (Rosmarinus officinalis), basil (Ocimum basilicum), sage (Salvia officinalis), thyme (Thymus vulgaris), and mints (Mentha spp.). In addition to the Lamiaceae family, RA is also present in plants from other families, such as Boraginaceae and Apiaceae.
-Rosmarinic acid is one of the hydroxycinnamic acids, and was initially isolated and purified from the extract of rosemary, a member of mint family (Lamiaceae)
-Its chemical structure allows it to act as a free radical scavenger by donating hydrogen atoms to stabilize ROS and free radicals.
RA’s dual nature as both a phenolic acid and a flavonoid-related compound enables it to chelate metal ions and prevent the formation of free radicals, thus interrupting oxidative chain reactions. It can modulate the activity of enzymes involved in OS, such as catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GPx), underscoring its potential role in preventing oxidative damage at the cellular level.
-divided as rosemary extract, carnosic acid, rosmarinic acid?

Summary:
-Capacity to chelate transition metal ions, particularly ironChelator (Fe2+) and copper (Cu2+)
-RA plus Cu(II)-induced oxidative DNA damage, which causes ROS
-rosmarinic acid (RA) as a potential inhibitor of MARK4↓ (inhibiting to tumor growth, invasion, and metastasis) activity (IC50 = 6.204 µM)

-Note half-life 1.5–2 hours.
BioAv water-soluble, rapid absorbtion
