Interactions between artemisinin derivatives and P-glycoprotein.

Area of Science:

• Pharmacology
• Oncology
• Drug Discovery

Background:

• Artemisinin, discovered in 1972, revolutionized antimalarial therapy.
• Artemisinin derivatives demonstrate significant anticancer potential in preclinical and clinical studies.
• P-glycoprotein (P-gp) mediated multi-drug resistance (MDR) is a major obstacle in cancer chemotherapy.

Purpose of the Study:

• To systematically review the interactions between artemisinin derivatives and P-gp.
• To assess the impact of artemisinin derivatives on P-gp expression levels.

Main Methods:

• Systematic literature review.
• Analysis of studies investigating artemisinin derivatives and P-gp interactions.
• Evaluation of P-gp expression modulation by artemisinin derivatives.

Main Results:

• Artemisinin derivatives display diverse interactions with P-gp.
• Existing artemisinin derivatives are not P-gp substrates, but novel ones may be.
• Many artemisinin derivatives inhibit P-gp, showing potential to reverse MDR for existing anticancer drugs.

Conclusions:

• Understanding artemisinin derivative-P-gp interactions is crucial for developing new anticancer agents.
• These findings support the design of artemisinin-based combination therapies to overcome P-gp mediated MDR in cancer treatment.
