Abstract:
An in vitro method of inactivating a viral, bacterial or protozoan pathogen in mammalian blood or a mammalian blood product comprising:(a) contacting in vitro a first composition comprising the mammalian blood or the mammalian blood product, suspected of containing the pathogen, with a pathogen inactivating amount of a compound I that has a nucleic acid binding ligand and a mustard group attached thereto, wherein compound I has a greater inactivation efficiency against R17 than a compound II containing a mustard group that lacks the nucleic acid binding ligand when incubated with a second composition comprising mammalian blood or a mammalian blood product, and wherein the pathogen inactivating amount results in the inactivation of at least 1 log of pathogen present in the first composition comprising the blood or blood product, if any,(b) and recovering the pathogen inactivated mammalian blood or mammalian blood product, wherein the recovered blood or blood product has substantially the same biological activity such that it is suitable for therapeutic use in a mammal.
