Snake venom may become tool in fight against coronavirus

September 2, 2021 10:40 AM


Brazilian researchers have found that snake venom could be used as a tool in the fight against coronavirus, discovering that a molecule in the venom of a type of snake slowed down the reproduction of coronavirus in monkey cells. 

The Brazilian scientists said they have discovered that a native viper’s venom can be used as a drug to help combat Covid-19.

In the scientific journal Molecules, scientists shared results from a study on monkey cells showing that a molecule from a Brazilian jararacussu pit viper can inhibit the virus’ ability to multiply by 75 percent.

A molecule in the venom can connect to the enzyme of the virus, PLPro, which is vital to the reproduction of the virus. "We were able to show this component of snake venom was able to inhibit a very important protein from the virus," University of São Paulo professor Rafael Guido told a British news agency.

Scientists will now evaluate the efficiency of different doses of the molecule, seeking to determine if it can prevent the virus from entering cells.

The discovery also sparked some concerns. Herpetologist Giuseppe Puorto said that he worries about people travelling around the country trying to be cured by the viper’s venom. "We're wary about people going out to hunt the jararacussu around Brazil, thinking they're going to save the world. ... That's not it!" Puorto said, adding "It's not the venom itself that will cure the coronavirus."

The jararacussu pit viper is also one of the largest snakes in Brazil, measuring up to 6 feet, 2 inches. 

Covid-19 cases and deaths are trending downward in Brazil, which has been among the hardest-hit countries in the world.

Much of the world is going through another wave of Covid-19 infections as the highly contagious Indian Delta variant spreads mostly among those who are unvaccinated.
