Synthesis of cordycepin: Current scenario and future perspectives

Abstract

Cordyceps genus, such as C. militaris and C. kyushuensis, is a source of a rare traditional Chinese medicine that has been used for the treatment of numerous chronic and malignant diseases. Cordycepin, 3'-deoxyadenosine, is a major active compound found in most Cordyceps. Cordycepin exhibits a variety of biological activities, including anti-tumor, immunomodulation, antioxidant, and anti-aging, among others, which could be applied in health products, medicine, cosmeceutical etc. fields. This review focuses on the synthesis methods for cordycepin. The current methods for cordycepin synthesis involve chemical synthesis, microbial fermentation, in vitro synthesis and biosynthesis; however, some defects are unavoidable and the production is still far from the demand of cordycepin. For the future study of cordycepin synthesis, based on the illumination of cordycepin biosynthesis pathway, genetical engineering of the Cordyceps strain or introducing microbes by virtue of synthetic biology will be the great potential strategies for cordycepin synthesis. This review will aid the future synthesis of the valuable cordycepin.
