| Honokiol is a Lignan isolated from bark, seed cones and leaves of trees of Magnolia species. Honokiol was traditionally used for anxiety and stroke treatment, as well as the alleviation of flu symptoms. -considered to have antioxidant properties -low oral bioavailability and difficulty in intravenous administration -the development of various formulations of honokiol, including microemulsion, liposomes, nanoparticles and micelle copolymers have successfully solved the problem of low water solubility. Pathways: -Inhibit NF-κB activation -Downregulate STAT3 signalin -Inhibiting the PI3K/Akt pathway, -Inhibition of mTOR -Influences various MAPK cascades—including ERK, JNK, and p38 -Inhibition of EGFR -Inhibiting Notch pathway (CSCs) -GPx4 inhibit -Can induce ER stress in cancer cells, which contributes to the activation of unfolded protein response (UPR) pathways -Disrupt the mitochondrial membrane potential in cancer cells. -Reported to increase ROS production in cancer cells -Can exhibit antioxidant properties in normal cells. - has some inhibitor activity but Not classified as HDAC inhibitor as weaker and may work more indirectly. - is well-known in the research community for its role in activating SIRT3 -Note half-life 40–60 minutes BioAv Pathways: - induce ROS production in cancer cells, and typically lowers ROS in normal cells - ROS↑ related: MMP↓(ΔΨm), ER Stress↑, GRP78↑, Ca+2↑, Cyt‑c↑, Caspases↑, DNA damage↑, cl-PARP↑, HSP↓ Prx - Raises AntiOxidant defense in Normal Cells: ROS↓, NRF2↑, SOD↑, GSH↑, Catalase↑, - lowers Inflammation : NF-kB↓, COX2↓, Pro-Inflammatory Cytokines : IL-1β↓, TNF-α↓, IL-6↓, - inhibit Growth/Metastases : TumMeta↓, TumCG↓, EMT↓, MMPs↓, MMP2↓, MMP9↓, VEGF↓, ROCK1↓, RhoA↓, NF-κB↓, CXCR4↓, ERK↓ - reactivate genes thereby inhibiting cancer cell growth : HDAC↓, EZH2↓, P53↑, HSP↓, - cause Cell cycle arrest : TumCCA↑, cyclin D1↓, cyclin E↓, CDK2↓, CDK4↓, CDK6↓, - inhibits Migration/Invasion : TumCMig↓, TumCI↓, ERK↓, EMT↓, - inhibits glycolysis and ATP depletion : HIF-1α↓, cMyc↓, GLUT1↓, LDH↓, LDHA↓, HK2↓, PDKs↓, ECAR↓, OXPHOS↓, GRP78↑, GlucoseCon↓ - inhibits angiogenesis↓ : VEGF↓, HIF-1α↓, Notch↓, EGFR↓, - inhibits Cancer Stem Cells : CSC↓, CD133↓, β-catenin↓, sox2↓, nestin↓, OCT4↓, - Others: PI3K↓, AKT↓, JAK↓, STAT↓, Wnt↓, β-catenin↓, AMPK, ERK↓, JNK, TrxR**, - Shown to modulate the nuclear translocation of SREBP-2 (related to cholesterol). - Synergies: chemo-sensitization, chemoProtective, RadioSensitizer, RadioProtective, Others(review target notes), Neuroprotective, Cognitive, Renoprotection, Hepatoprotective, CardioProtective, - Selectivity: Cancer Cells vs Normal Cells

| 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. |
