Description

Dihydroartemisinin is a potent, semi-synthetic derivative of artemisinin and a key active pharmaceutical ingredient (API) in antimalarial therapies. Its primary value lies in its high efficacy against Plasmodium falciparum malaria, including strains resistant to chloroquine and other drugs. This compound is essential for manufacturers in the pharmaceutical industry producing combination therapies (ACTs) and for research institutions developing new antiparasitic formulations.

Application

• Active Pharmaceutical Ingredient (API) in Artemisinin-based Combination Therapies (ACTs) for malaria treatment.
• Pharmaceutical Intermediates for the synthesis of more complex artemisinin derivatives.
• Biomedical Research for studying antimalarial mechanisms of action and drug resistance.
• Reference Standard in analytical laboratories for quality control and method validation.
• Veterinary Pharmaceuticals for the treatment of parasitic infections in animals.
• Preclinical & Clinical Development of new antiparasitic and potential anticancer agents.
