Acyclovir-d4 is intended for use as an internal standard for the quantification of acyclovir by GC- or LC-MS. Acyclovir is a guanosine analog that has antiviral activity in vitro against the herpes simplex viruses, varicella zoster virus, Epstein-Barr virus, cytomegalovirus, and human herpes virus 6 (ID50s = 0.1-63.1 μM).1 It diffuses freely into cells and is selectively converted into acyclo-guanosine monophosphate by a virus-specific thymidine kinase. During DNA replication, the phosphorylated form of acyclovir is preferentially incorporated into viral DNA, resulting in premature chain termination and inhibition of further DNA polymerase activity.2 Acyclovir (5 mg/kg) reduces viral titers in mice infected with the herpes simplex virus-1 (HSV-1) strain SC16.3

Controlled ex-vivo plasma hydrolysis of valaciclovir to acyclovir demonstration using tandem mass spectrometry
Biomed Chromatogr 2011 Nov;25(11):1189-200.PMID:21400550DOI:10.1002/bmc.1590
Plasma estimation of valaciclovir, an antiviral drug, is challenging due to both in-vivo and ex-vivo hydrolysis to active metabolite acyclovir. A simultaneous method is described involving the solid-phase ion-exchange extraction procedure requiring 100 μL of plasma volume, a reverse-phase Lichrosphere RP Select B (125 × 6 mm, 5 μm) column and isocratic mobile phase to achieve the desired chromatographic separation. ESI-MS/MS multiple reaction monitoring in positive polarity, detected mass pairs for valaciclovir (m/z 325.5 → 152.2), acyclovir (m/z 226.3 → 152.2) and respective internal standards valganciclovir (m/z 307.1 → 220.3) and Acyclovir-d4 (m/z 230.2 → 152.0). Fully fledged method validation was evaluated as per current regulatory requirements and results were deemed acceptable. The plasma samples showed extensive hydrolysis of valaciclovir when collected or processed at room temperature, without buffer stabilization prior to storage at -15°C. Our results showed that using prechilled K3 EDTA vacutainers immersed in an iced-water bath during blood sample collection, and addition of 50% orthophosphoric acid solution to plasma samples prior to storage at -50°C for at least 120 days controlled the hydrolysis of valaciclovir to acyclovir. While monitoring drug absorption into systematic circulation, the valaciclovir to acyclovir formation ratio was improved to 1:20 in healthy volunteers for the first time.
