Gizmodo's Ed Cara explains why HIV drugs are being used to treat the new coronavirus. An anonymous reader shares the report: On Tuesday, the Japanese government announced it will begin clinical trials to test treatments for the deadly new coronavirus that's engulfed China and spread to over two dozen countries. Rather than new drugs, they'll be studying existing medications already used to treat HIV and other viral diseases. But why exactly are researchers hopeful that these drugs can be repurposed for the new coronavirus, and how likely are they to work? The new coronavirus, recently named SARS-CoV-2 due to its close genetic ties to the SARS coronavirus, is made out of RNA. Other RNA viruses include the ones that cause Ebola, hepatitis C, and yes, HIV/AIDS. RNA viruses come in all shapes and sizes, and those that infect humans can do so in different ways. But many of the drugs that go after HIV and the hepatitis C virus broadly target weaknesses found in all sorts of viruses. The approved hepatitis C drug ribavirin, for instance, interferes with something called the RNA-dependent RNA polymerase, an enzyme essential for many viruses -- including coronaviruses -- to produce more of themselves inside a cell. HIV drugs like lopinavir inhibit other enzymes that allow viruses to break down certain proteins, which cripples their ability to infect cells and replicate. Broad antiviral drugs like lopinavir should be able to work against SARS-CoV-2, scientists theorize. And there's already some circumstantial evidence they do. Some of these drugs have been successfully tested out for SARS and MERS, for instance, two other nasty coronaviruses that have emerged in recent years.
