Acyclovir-d4 is the deuterium labeled Acyclovir. Acyclovir (Aciclovir) is a guanosine analogue and an orally active antiviral agent. Acyclovir inhibits HSV-1 (IC50 of 0.85 µM), HSV-2 (IC50 of 0.86 µM) and varicella-zoster virus. Acyclovir can be phosphorylated by viral thymidine kinase (TK), and Acyclovir triphosphate interferes with viral DNA polymerization through competitive inhibition with guanosine triphosphate and obligatory chain termination[1][2][3]. Acyclovir prevents bacterial infections during induction therapy for acute leukaemia[4].
