Background:
L-Valacyclovir-d8is intended for use as an internal standard for the quantification of L-valacyclovir by GC- or LC-MS. L-Valacyclovir is an L-valyl prodrug form of the antiviral guanosine analog acyclovir . L-Valacyclovir inhibits herpes simplex virus type 1 (HSV-1) replication (IC50= 0.84 µM in Vero cells).1It is more potent than the stereoisomer D-valacyclovir but less potent than acyclovirin vitro, however, it is rapidly converted to acyclovirin vivo.2Formulations containing L-valacyclovir have been used in the treatment of HSV-1 infections.
