Amotosalen (S-59, psoralen derivative), a chemical capable of binding to nucleic acids is added to platelets. UVA illumination (320 – 400 nm wavelengths) of amotosalen-treated platelet components induces covalent cross-linking of any nucleic acids to which amotosalen is bound; thereby, preventing further replication. Amotosalen is used in the INTERCEPT process to cross-link DNA and RNA. Amotosalen has protective activity against pathogens such as bacteria, viruses, protozoa, and leukocytes. Prior to administration amotosalen is added to plasma and platelets, then in vivo this agent penetrates pathogens and targets DNA and RNA. Upon activation by ultraviolet A light, amotosalen forms interstrand DNA and RNA crosslinks and prevents replication. Thus, the pathogen-inactivation system using amotosalen/ultraviolet A offers the potential to mitigate the risk of ZIKV transmission by plasma and platelet transfusion. Inactivation of leukocytes can prevent graft versus host disease upon transfusion.
