Now sharks instead of taking lives of humans will be saving their lives. Recently, scientists have found that there exists a compound in sharks, which by isolating from them could be used as a distinctive, wide-ranging antiviral agent for humans. This compound is known as squalamine and it tends to fight against human viruses. So from now onwards, let it be dengue, yellow fever or hepatitis B, C, or D - doctors will be having cure for all of them.

Clinical trials are still going on to confirm the effectiveness of the compound in the treatment of cancer and several eye disorders. If things go well, then the compound will be granted with a certificate of safety profile and it will be classified as a new class of drugs for treating infections that are caused by different viruses.

Till now, few experiments with this drug over animals have been made and in all of them squalamine successfully verified its antiviral activity against even those human pathogens to which till now there was no cure.

As said by study's lead investigator Michael Zasloff, Professor of surgery and pediatrics at Georgetown University Medical Centre and Scientific Director of the Georgetown Transplant Institute, "Squalamine appears to protect against viruses that attack the liver and blood tissues, and other similar compounds that we know exist in the shark likely protect against respiratory viral infections, and so on".
