Phytother Res. 2015 Jul;29(7):969-77. doi: 10.1002/ptr.5348. Epub 2015 Apr 24.


Isoliquiritigenin (ISL) is one of the bioactive ingredients isolated from the roots of plants belonging to licorice, including Glycyrrhiza uralensis, Mongolian glycyrrhiza, Glycyrrhiza glabra, and so forth. Liquiritigenin is available in common foods and alternative medicine, and its derivative-ISL is applied into food additives and disease treatment like cancer therapy, antibiotic therapy, and so on. This review aims at providing a comprehensive summary of the pharmacological activities of ISL. The information published between 1972 and 2014 from a number of reliable sources including PubMed, ScienceDirect, Springer, and Wiley-Blackwell. The practical application of ISL on the various disease prevention and treatments may stem from its numerous pharmacological properties such as antiinflammatory, anti-microbial, anti-oxidative, anticancer activities, immunoregulatory, hepatoprotective, and cardioprotective effects. However, further studies are needed to verify the target-organ toxicity or side effects investigation.
