Rosmarinic acid / MAPK 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.

Summary:
-Capacity to chelate transition metal ions, particularly ironChelator (Fe2+) and copper (Cu2+)
-RA plus Cu(II)-induced oxidative DNA damage, which causes ROS

-Note half-life 1.5–2 hours.

- 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


MAPK, mitogen-activated protein kinase: Click to Expand ⟱
Source: CGL-CS
Type:
Mitogen-activated protein kinases (MAPKs) are a group of proteins involved in transmitting signals from the cell surface to the nucleus, playing a crucial role in various cellular processes, including growth, differentiation, and apoptosis (programmed cell death).

MAPK Pathways: The MAPK family includes several pathways, the most notable being:
1.ERK (Extracellular signal-Regulated Kinase): Often associated with cell proliferation and survival.
2.JNK (c-Jun N-terminal Kinase): Typically involved in stress responses and apoptosis.
3.p38 MAPK: Associated with inflammatory responses and apoptosis.

Inhibitors: Targeting the MAPK pathway has become a strategy in cancer therapy. For example, BRAF inhibitors (like vemurafenib) are used in treating melanoma with BRAF mutations.
Altered Expression Levels:
Overexpression: Many cancers exhibit overexpression of MAPK pathway components, such as RAS, BRAF, and MEK. This overexpression can lead to increased signaling activity, promoting cell proliferation and survival.
Downregulation: In some cases, negative regulators of the MAPK pathway (e.g., MAPK phosphatases) may be downregulated, leading to enhanced MAPK signaling.
The expression levels of MAPK pathway components can serve as biomarkers for cancer diagnosis, prognosis, and treatment response. For example, high levels of phosphorylated ERK (p-ERK) may indicate active MAPK signaling and poor prognosis in certain cancers.

Numerous reports indicate that the MAPK pathway plays a major role in tumor progression and invasion, while inhibition of MAPK signaling reduces invasion.
