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.

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.

Type:
A radiosensitizer is an agent that makes cancer cells more sensitive to the damaging effects of radiation therapy. By using a radiosensitizer, clinicians aim to enhance the effectiveness of radiation treatment by either increasing the damage incurred by tumor cells or by interfering with the cancer cells’ repair mechanisms. This can potentially allow for lower doses of radiation, reduced side effects, or improved treatment outcomes.
Pathways that help Radiosensitivity: downregulating HIF-1α, increase SIRT1, Txr

List of Natural Products with radiosensitizing properties:
-Curcumin:modulate NF-κB, STAT3 and has been shown in preclinical studies to enhance the effects of radiation by inhibiting cell survival pathways.
-Resveratrol:
-EGCG:
-Quercetin:
-Genistein:
-Parthenolide:

-gold nanoparticles (GNPs),
-gold triethylphosphine cyanide ([Au(SCN) (PEt3)]),
-auranofin, ceria nanoparticles (CONPs),
-curcumin and its derivatives,
