From Spice to Therapy: The Antiangiogenic Potential of Eugenol

Nyctanthes Antiangiogenesis, the process of inhibiting new blood vessel formation, has become a pivotal strategy in the treatment of cancer and other angiogenesis-dependent diseases. Eugenol, a bioactive compound found in clove oil, has gained attention for its broad pharmacological properties, including anti-inflammatory, antioxidant, and anticancer effects. Recent studies suggest that eugenol exhibits significant antiangiogenic potential by targeting key regulators of angiogenesis, such as Vascular Endothelial Growth Factor (VEGF) and Matrix Metalloproteinases (MMPs). This review examines the molecular mechanisms underlying eugenol’s antiangiogenic activity, focusing on its ability to inhibit VEGF expression, disrupt endothelial cell migration, and reduce microvessel density in tumor models. Additionally, the therapeutic implications of eugenol as a natural antiangiogenic agent in cancer treatment, alongside its potential for overcoming resistance to conventional antiangiogenic therapies, are discussed. While promising, further research is needed to optimize its efficacy, bioavailability, and clinical application. This review highlights the growing interest in natural compounds like eugenol as complementary or alternative strategies in antiangiogenesis therapy.
