[Application of zebrafish in drug screens for active ingredients]

Zebrafish has unique advantages over other animal models in the aspect of drug screens for active ingredients and gains more and more attentions in drug research and development recently. Thus, this article reviews the recent advance of zebrafish-based drug screens in Chinese traditional medicine (TCM) effective part research, monomer drug screening, activity evaluation of natural products, discovery of new uses for old drugs, and toxicity assessment in early-phase drug discovery.
