Annona Muricata (Soursop): The Natural Enemy of Cancer -A Comprehensive Review
Abstract
Annona muricata (commonly known as soursop or graviola) is a tropical plant widely recognized for its traditional medicinal applications and growing scientific interest, particularly for its anticancer potential. This review presents a comprehensive analysis of the phytochemical profile, pharmacological activities, and mechanisms underlying the anticancer effects of A. muricata. The plant is rich in annonaceous acetogenins, alkaloids, flavonoids, and phenolic compounds, with acetogenins such as annonacin and bullatacin demonstrating potent cytotoxicity against various cancer cell lines including breast, prostate, colon, pancreatic, and liver cancers. Mechanistically, these compounds induce apoptosis through mitochondrial dysfunction, arrest cell cycle progression, and inhibit key signaling pathways such as NF-κB and VEGF, effectively suppressing tumor growth and angiogenesis. Preclinical in vivo studies have confirmed tumor regression, enhanced antioxidant defense, and minimal systemic toxicity. However, concerns regarding annonacin-induced neurotoxicity and the lack of clinical trials limit its current therapeutic use. Innovative delivery systems, such as nanoformulations and lipid-based carriers, have shown promise in improving bioavailability and reducing toxicity. Despite the encouraging evidence, clinical validation remains absent, and standardized protocols for dosage, extract preparation, and safety are urgently needed. This review emphasizes the need for translational research to bridge the gap between traditional use and modern oncology. With rigorous scientific validation and regulatory oversight, Annona muricata holds the potential to emerge as a natural and effective anticancer agent.
