A 5% ointment acycloguanosine was tried in the treatment of recurrent herpes simplex of the skin and genitalia in 48 patients. The treatment brought limitation of the process, relief of the symptoms, control of local manifestations and toxicity, accelerated epithelization, complete regression and disappearance of the eruption.

The quinoid pigment echinochrome A isolated from the sea urchin Scaphechinus mirabilis, the product of its oxidation dehydroechinochrome, and structurally similar antiviral agent oxolin were tested for their ability to inhibit plaque formation induced by herpes simplex virus type 1 (HSV-1) in Vero cells. The tested compounds showed significant anti-HSV-1 activity, mainly due to their direct effect on viral particles and on virus attachment to cells. The antiviral efficacy of the test compounds increased in the following order: oxolin→echinochrome A→dehydroechinochrome.

Herpes simplex viruses (HSV) are leading causes of human infections which result in severe manifestations, especially in neonates, immunocompromised and/or transplanted individuals. Current HSV type-1 (HSV-1) resistance to standard antiviral agents is a therapeutic challenge, especially for treating immunocompromised patients.. Herein we describe the promising antiviral profile of three 2-aminomethyl-3-hydroxy-1,4-naphthoquinones against HSV-1 using Vero cells.. The in silico theoretical analysis indicated that the lowest unoccupied molecular orbital (LUMO) and the conformational features of these molecules are important structural features for modulating their biological activity. Our in vitro results showed that these compounds have significant anti-HSV-1 activity comparable to acyclovir, the antiviral currently used clinically. Importantly two of them showed a lower cytotoxicity profile against Vero cells than acyclovir. The inhibitory mechanism analysis using a time-of-addition assay revealed that all compounds inhibit the late phase of lytic replication. Finally, the highest selectivity index of the first tested compound was almost twice as high as that of acyclovir.. Since resistance is still a problem for treating HSV infections, these compounds present a promising profile toward the development of new strategies for anti-HSV-1 therapy.
