BBC News reports that squalamine, a chemical found in the Squalidae family (dogfish) of sharks, has been found to be a “good antiviral candidate” due to its documented ability to kill a wide range of human and animal viruses. While more research needs to be done to investigate the potential use of the chemical as a means of treatment for human diseases, squalamine can be easily reproduced synthetically and has shown no signs of major adverse side effects when given to patients in clinical trials to stop the growth of cancer cells, according to the BBC report.
