Biochem/physiol Actions. Famciclovir is an antiretroviral guanosine analog used to treat herpesvirus infections and hepatitis B. Famciclovir is rapidly converted to penciclovir. Viral thymidine kinase phosphorylates penciclovir to a monophosphate form that celular kinases convert in turn to penciclovir triphosphate.

Oleum (Latin oleum = oil), or fuming sulfuric acid, is a solution of various compositions of sulfur trioxide in sulfuric acid, or sometimes more specifically to disulfuric acid (also known as pyrosulfuric acid).Oleums can be described by the formula y SO 3 .H 2 O where y is the total molar sulfur trioxide content.hey can also be described by the formula H 2 SO 4. x SO 3 where x is now defined as the molar free sulfur trioxide content. Oleum is generally assessed according to the free SO 3 content by weight. It can also be expressed as a percentage of sulfuric acid strength; for oleum concentrations, that would be over 100%.
