Artemisinin-Based Therapies: New Developments in Synthesis, Drug Delivery, and Medical Applications

What is it about?

Artemisinin, a natural compound derived from Artemisia annua, has significantly impacted the treatment of malaria and has shown promise in various other therapeutic applications. This review explores the molecular structure of artemisinin and its derivatives, as well as advancements in synthetic and semi-synthetic production methods, and their broader therapeutic effects beyond malaria, including potential uses in cancer, neurological disorders, and viral infections. It also discusses contemporary drug delivery innovations, such as nanoparticles and liposomal systems, which aim to enhance the bioavailability and targeted action of artemisinin, while addressing issues of drug resistance, particularly in parasitic diseases like malaria. The future of artemisinin research is expected to focus on the development of novel derivatives and innovative formulations that leverage nanomedicine, with significant implications for global health and improved therapeutic efficacy.

Why is it important?

1. Addressing antimalarial drug resistance: Artemisinin-based combination therapies are essential for malaria treatment, but the emergence and spread of partial artemisinin resistance threaten their effectiveness. Reviewing resistance mechanisms, therapeutic limitations, and strategies to preserve drug efficacy is important for global malaria control. 2. Advancing medicinal chemistry and drug synthesis: Artemisinin has a distinctive endoperoxide bridge that is central to its antimalarial activity. Understanding its structure–activity relationships and advances in synthetic and semi-synthetic production can support the development of novel derivatives with improved potency, stability, pharmacokinetic properties, and therapeutic selectivity. 3. Exploring therapeutic applications beyond malaria: Emerging research investigates artemisinin derivatives in cancer, neurological disorders, and viral infections. A critical synthesis of these findings can identify promising molecular mechanisms, therapeutic opportunities, and research gaps, while distinguishing preliminary laboratory evidence from established clinical efficacy. 4. Improving drug delivery and bioavailability: Limitations such as poor aqueous solubility, rapid metabolism, and inadequate drug exposure may restrict the therapeutic potential of certain artemisinin derivatives. Nanoparticles, liposomes, and other advanced delivery systems may improve drug stability, distribution, controlled release, and targeted delivery. 5. Integrating chemistry, pharmacology, and nanomedicine: The review brings together molecular design, production technologies, biological mechanisms, resistance, and formulation strategies. This interdisciplinary perspective can help researchers identify how chemical modification and delivery-system optimisation may complement each other. 6. Identifying future research priorities: By evaluating current evidence and unresolved challenges, the review can guide future investigations into scalable production, safer and more effective derivatives, formulation optimisation, toxicity, pharmacokinetics, and clinical translation.
