Abstract
The present invention demonstrates a method of photodynamic inactivation of viruses having a membranous envelope, such as Herpes simplex type 1 and Human immunodeficiency type 1 viruses. The method uses substituted sapphyrin compounds to effect viral deactivation during radiation with light at or near the absorption wavelength of the sapphyrin compound. A highly reactive species selectively toxic to infectious agents is produced. One particular sapphyrin compound useful for the practice of the invention is 8,17-bis(carboxymethyl)-3,12,13,22-tetraethyl-2,7,18,23-tetramethylsapphyr in (Sapphyrin 2). The most preferred sapphyrin sapphyrin compound for the practice of the invention is 3,8,12,13,17,22-hexaethyl-2,7,18,23-tetramethylsapphyrin (Sapphyrin 1). The method is particularly suitable for inactivation of viruses in blood and blood products.
