About the B-220 compound.

Vironova’s B-220 lead compound in the approved US patent for topical administration against herpes was first discovered over 4 decades ago by Professor Jan Bergman who was sponsored to synthesize the compound by the Swedish pharmaceutical company Kabi.

B-220 and analogues of the compound are known to have a broad-spectrum anti-viral effect against all viruses tested from the herpesvirus group i.e. herpes simplex virus type (HSV-1) and type 2 (HSV-2), Cytomegalovirus (CMV) and Varicella zoster virus (VZV). B-220 appears to inhibit viral replication at different stages of the virus cycle compared to commercially available standard anti-herpes treatments containing acyclovir.

Acyclovir is the standard treatment option available today, however it is not a cure for herpes infections.
