Marine organisms as a therapeutic source against herpes simplex virus infection

Abstract

Herpes simplex virus (HSV) is a member of the Herpesviridae family that causes general communicable infections in human populations throughout the world, the most common being genital and orolabial disease. The current treatments for HSV infections are nucleoside analogs such as acyclovir, valacyclovir and famciclovir. Despite the safety and efficacy, extensive clinical use of these drugs has led to the emergence of resistant viral strains, mainly in immunocompromised patients. To counteract these problems, alternative anti-HSV agents from natural products have been reported. Recently, a great deal of interest has been expressed regarding marine organisms such as algae, sponges, tunicates, echinoderms, mollusks, shrimp, bacteria, and fungus as promising anti-HSV agents. This contribution presents an overview of potential anti-HSV agents derived from marine organisms and their promising application in HSV therapy.
