Vidarabine (VDB)
Vidarabine is an antiviral drug which is active against herpes simplex and varicella zoster viruses. Vidarabine works by interfering with the synthesis of viral DNA. It is a nucleoside analog and therefore has to be phosphorylated to be active. This is a three step process in which vidarabine is sequentially phosphorylated by kinases to the triphosphate ara-ATP. This is the active form of vidarabine and is both an inhibitor and a substrate of viral DNA polymerase. When used as a substrate for viral DNA polymerase, ara-ATP competitively inhibits dATP leading to the formation of ‘faulty’ DNA. This is where ara-ATP is incorporated into the DNA strand replacing many of the adenosine bases. Vidarabine triphosphate (ara-ATP) also inhibits RNA polyadenylation; preventing polyadenylation essential for HIV-1 and other retroviruses; and S-adenosylhomocysteine hydrolase, preventing transmethylation reactions.
