Rosmarinic acid / Rho Cancer Research Results

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
Pathways:
- varying results of ROS up or down in cancer cells. Plus a report of lowering ROS and no effect on Tumor cell viability.
However always seems to lower ROS↓ in normal cells.

- inhibits angiogenesis↓ : VEGF↓, HIF-1α↓, EGFR↓,
- inhibits Cancer Stem Cells (few references) : CSC↓, Hh↓, GLi1↓,
- Others: PI3K↓, AKT↓, STAT↓, AMPK, ERK↓, JNK,

- Selectivity: Cancer Cells vs Normal Cells

Rank Pathway / Axis Cancer Cells Normal Cells Label Primary Interpretation Notes
1 Reactive oxygen species (ROS) ↓ ROS (dominant antioxidant effect) ↓ ROS Driver Antioxidant / redox buffering Rosmarinic acid is a strong phenolic antioxidant; cancer effects are largely redox-modulatory rather than cytotoxic
2 NF-κB signaling ↓ NF-κB activation ↓ inflammatory NF-κB tone Secondary Suppression of inflammatory survival signaling NF-κB inhibition explains anti-inflammatory, anti-proliferative, and chemopreventive effects
3 MAPK signaling (ERK / JNK / p38) ↓ ERK; ↑ JNK/p38 (context-dependent) ↔ minimal Secondary Stress-modulated signaling MAPK modulation reflects redox-sensitive signaling rather than direct kinase inhibition
4 Cell cycle regulation ↑ G0/G1 arrest (mild) ↔ spared Phenotypic Cytostatic growth control Growth inhibition is modest and non-cytotoxic in most models
5 Apoptosis ↑ apoptosis (weak / context-dependent) ↓ apoptosis Phenotypic Threshold-dependent cell death Apoptosis is not a dominant mechanism and usually requires high doses or co-stress
6 NRF2 antioxidant response ↑ NRF2 (adaptive) ↑ NRF2 (protective) Adaptive Antioxidant gene induction NRF2 activation reflects reinforcement of antioxidant capacity

The Rho GTPases RhoA, Rac1, and Cdc42 are important regulators of cytoskeletal dynamics. small GTPase Ras homolog gene family member A (RHOA)
RHOA: Ras homolog family member A
Many in vitro and in vivo data indicate tumor-promoting effects of activated Rho GTPases, also tumor suppressive functions have been described.
In many cancers, RhoA and RhoC are often found to be overexpressed.
RhoB expression can be downregulated in certain cancers, which may contribute to tumor progression. Unlike RhoA and RhoC, RhoB is often considered a tumor suppressor, and its loss can lead to increased cell proliferation and survival.
-RhoA activity has been linked to the modulation of EMT, influencing both the disassembly of cell–cell junctions and the reorganization of the cytoskeleton necessary for migration.
-Elevated levels or hyperactivation of RhoA has been associated with poor prognosis in several cancers.
