Compounds and methods for inactivating pathogens in materials are described, including compositions and methods for inactivating pathogens in biological materials such as red blood cell preparations and plasma. The compounds and methods may be used to treat materials intended for in vitro or in vivo use, such as clinical testing or transfusion. The compounds are designed to specifically bind to and react with nucleic acid, and then to degrade to form breakdown products. The degradation reaction is preferably slower than the reaction with nucleic acid.

Les compositions et les procédés peuvent être utilisés pour le traitement de matériaux destinés à une utilisation $i(in vitro) ou $i(in vivo) telle qu'essai clinique ou transfusion. Les composés sont conçus de manière à se lier spécifiquement à un acide nucléique et à réagir avec ledit acide et, ensuite, à se dégrader sous forme de produits de fractionnement. La réaction de dégradation est, de préférence plus lente que la réaction avec l'acide nucléique.

Methods are provided for quenching undesired side reactions of pathogen inactivating compounds in biological materials. In a particular embodiment, methods are provided for quenching undesired side reactions of a pathogen inactivating compound that includes a functional group which is, or which is capable of forming, an electrophilic group. In this embodiment, the material is treated with the pathogen inactivating compound and a quencher, wherein the quencher comprises a nucleophilic functional group that is capable of covalently reacting with the electrophilic group. The electrophilic group on the pathogen inactivating compound is preferably a non-radical cationic group. In one embodiment, the pathogen inactivating compound includes a nucleic acid binding ligand and a mustard group, wherein the mustard group is capable of reacting in situ to form the electrophilic group. Preferred quenchers are thiols, such as glutathione. Biological materials which may be treated include whole blood, red blood cells, blood plasma, and platelets. The methods permit inhibition of the modification of red blood cells in red blood cell containing materials during pathogen inactivation.
