Drugs in development for herpes simplex and varicella zoster virus.

ABSTRACT

The alpha-herpesviruses varicella zoster virus (VZV) and herpes simplex virus (HSV) share common features including lifelong persistence in sensory ganglia and the risk of recurrences. For both HSV and VZV, standard-of-care (SoC) is based on nucleoside analogs (NAs), which require specific activation in infected cells. These existing drugs exhibit substantial limitations, warranting the development of new and more effective drugs.
