Displaying 1 results of Grazoprevir Stable Isotopes Grazoprevir is a potent inhibitor of the hepatitis C virus protease and is used in the treatment of hepatitis C infections. Stable isotopes of Grazoprevir are isotopic variants of the molecule that have the same number of protons and electrons, but a different number of neutrons. These isotopes are used in research to study the pharmacokinetics and metabolism of Grazoprevir in the body. They are also used in the development of new drugs and therapies for hepatitis C and other viral infections.
