Isolation of Marine Polyether Toxins

The chemical structure of marine biotoxins is very special, and the chemical structures of various toxins vary greatly. Among them, polyether toxin is the marine toxin with the most outstanding research progress in recent years. It is a natural toxin with a unique chemical structure, strong toxicity, and wide pharmacological effects. There are more than 100 polyether toxoids. Polyether toxins can be divided into 3 categories according to their chemical properties: aliphatic chain polyether toxins, macrolide polyether toxins, and ladder-shaped polyether toxins. The main representative toxins are matiotxin, ciguatoxin, and palytoxin. Research on polyether toxoids provides chemical and life sciences with information that is difficult to obtain from terrestrial natural products. Polyether toxoids are expected to play an important role in the development of new cardiovascular and antitumor drugs. In addition, the maturity of microbial isolation, culture, transformation, and fermentation technology has made it possible to obtain a large number of toxins, while the development of genetic engineering methods and biochemistry has made it easier for researchers to transform and utilize relatively small toxins.
