Ginseng-Based Nanotherapeutics in Cancer Treatment: State-of-the-Art Progress, Tackling Gaps, and Translational...

Among medicinal plants, the Panax genus (family: Araliaceae) includes plant species widely recognized for their multi-faceted pharmacological attributes. The triterpenoids, designated as ginsenosides, are increasingly recognized as drug-like molecules in cancer therapies due to their therapeutic role in restricting tumor invasion, proliferation, metastasis, apoptosis, and drug resistance reversal in tumor cells. In the nanobiotechnological era, nano-delivery systems provide feasible solutions to address bottlenecks associated with traditional drug delivery methods (low bioavailability, instability in the gastrointestinal tract, high dosage requirements, side effects, poor absorption, and incomplete drug utilization in the body). The dedicated efforts for precise and effective treatment have directed the development of ginsenoside-based nano-delivery systems to achieve potent anticancer efficacies and address the limitations in ginseng pharmacokinetics, facilitating drug development trials. Studies into ginseng pharmacokinetics showed a remarkable prolonged clearance and free drug levels of ~15% (ginsenoside RB1 nanoparticles) in mice (compared to only ~5% for ginsenosides) and better antitumor efficacies, demonstrating key success in ginseng biotechnology for drug development. Delving into the nanobiotechnological interventions in ginseng-derived therapeutics, this study summarizes current advances and achievements, particularly in cancer treatment, tackles existing gaps, focuses on feasible solutions, and examines prospects of translational success.
