Plant-derived medicaments: potential alternative for cancer therapy

Background. Despite the enrollment of new small molecules such as Sorafenib for the treatment of hepatocellular carcinoma (HCC), HCC still remains a significant contributor to cancer-related mortality and morbidity globally. Zanthoxylum zanthoxyloides is long suspected of possessing anticancer bioactive compounds that may hold the prospect of adjunctive therapy against inflammation-related cancers such as HCC. Objective. This study assessed the effects of an alkaloidal extract of the leaves of Zanthoxylum zanthoxyloides on CCl4/olive oil (1 : 1 v/v)-induced HCC-like phenotypes in rats. Materials and Methods. Zanthoxylum zanthoxyloides alkaloidal extract (ZZAE) was prepared using Soxhlet and liquid-liquid extraction methods. Subsequently, ZZAE was characterized phytochemically. In the curative method, experimental HCC was established in adult (8–10 weeks old) male Sprague-Dawley rats weighing 150–300 g by twice-daily administration of CCl4/olive oil (1 : 1 v/v) (2 mL/kg ip).
