Type:
Process through which new blood vessels.
Angiogenesis, the process of new blood vessel formation from pre-existing vessels, plays a crucial role in cancer progression and metastasis. Tumors require a blood supply to grow beyond a certain size and to spread to other parts of the body.
Vascular Endothelial Growth Factor (VEGF): VEGF is one of the most important pro-angiogenic factors. It stimulates endothelial cell proliferation and migration, leading to the formation of new blood vessels. Many tumors overexpress VEGF, which correlates with poor prognosis.
Hypoxia-Inducible Factor (HIF): In response to low oxygen levels (hypoxia), tumors can activate HIF, which in turn promotes the expression of VEGF and other angiogenic factors. This mechanism allows tumors to adapt to their microenvironment and sustain growth.

BioAv↓, Due to the concerns about poor aqueous solubility, liposomal formulations of honokiol have been developed and tested for their pharmacokinetics
Half-Life↝, In another comparative study, plasma honokiol concentrations was maintained above 30 and 10 μg/mL for 24 and 48 hours, respectively, in liposomal honokiol-treated mice, whereas it fell quickly (less than 5 μg/mL) by 12 hours in free honokiol-treated
Half-Life↝, free honokiol has poor GIT absorption, bio-transformed in liver to mono-glucuronide honokiol and sulphated mono-hydroxyhonokiol, ~ 50% is secreted in bile, ~ 60-65% plasma protein bound with elimination half life of (t1/2) of 49.05 – 56.24 minutes.
toxicity↓, These studies suggest that honokiol either alone or as a part of magnolia bark extract does not induce toxicity in animal models and thus could be clinically safe
