| Lignan found in bark of some magnolia species. Magnolol (MAG) — a bioactive biphenolic compound from Magnolia officinalis derived from the bark (roots and branches) of Magnolia species such as M. officinalis, M. obovata, and M. grandiflora The two main bioactive compounds isolated from these plants are MAG (5,5ʹ-diallyl-2,2ʹ-dihydroxybiphenyl) and Honokiol (3,5ʹ-diallyl-4,2ʹ-dihydroxybiphenyl) (Fig. 1) which are phenolic regioisomers. In the bark extracts of Magnolia plants, the composition of MAG ranges from 1 to 10%, while Honokiol comprises 1 to 5% Magnolol is a biphenolic neolignan isolated from the bark of Magnolia officinalis. It is structurally related to honokiol and is studied for anti-inflammatory, antioxidant, antimicrobial, and neuroactive effects. In preclinical oncology models, magnolol is reported to modulate NF-κB, STAT3, PI3K/AKT, MAPK, Wnt/β-catenin, and redox pathways, with downstream effects on cell-cycle arrest, apoptosis, invasion/EMT, and angiogenesis. Oral bioavailability is limited and many cytotoxic concentrations reported in vitro are in the tens of µM range, often above typical systemic levels from standard supplementation. major pathways and molecular targets involved in magnolol’s anticancer actions: -Apoptosis: ↑ Bax, ↓ Bcl-2, ↑ cytochrome c, ↑ caspase-9, ↑ caspase-3 -Arrests cell cycle at G0/G1 or G2/M phase:↓ Cyclin D1, CDK4, CDK6, Cyclin B1, CDK1 -Inhibits NF-κB activation: ↓ IκBα, COX-2, TNF-α -Inhibits PI3K, Akt, and mTOR phosphorylation -Suppresses angiogenesis: ↓ Bcl-XL, Mcl-1, VEGF, cyclin D1 -Inhibits β-catenin nuclear translocation -increase ROS production in tumor cells → triggers mitochondrial apoptosis -Magnolol activates Nrf2 in normal cells → upregulates HO-1, NQO1: Protects normal tissue from oxidative stress during chemotherapy or inflammation. Most in-vitro IC50 values fall in the 10–100 µM range, often above typical systemic exposure.

| Antiplatelet aggregation refers to the process by which platelets clump together to form a blood clot. The plethora of evidence indicates that among multiple hemostasis components, platelets play major roles in cancer progression by providing surface and granular contents for several interactions as well as behaving like immune cells.On the other hand, there are suggestions that antiplatelet treatment may promote solid tumor development in a phenomenon described as “cancers follow bleeding.” The controversies around antiplatelet agents justify insight into the subject to establish what, if any, role platelet-directed therapy has in the continuum of anticancer management. The interplay between antiplatelet aggregation and cancer is an area of active research, with potential implications for therapeutic strategies. Antiplatelet agents, such as aspirin, are being investigated for their role in cancer prevention and treatment, particularly in reducing metastasis and improving patient outcomes. |
