Psoralen compounds are synthesized which have substitutions on the 4, 4', 5' and 8 positions of the psoralen, which permit enhanced binding to nucleic acid of pathogens. Higher psoralen binding levels and lower mutagenicity are described, resulting in safer, more efficient, and reliable inactivation of pathogens in blood products. The invention contemplates methods for preparing substantially non-mutagenic blood products substantially free of nucleic acid, as well as said blood products as such, using the new psoralens which do not compromise the function of blood products for transfusion.
所合成的
补骨脂素化合物在
补骨脂素的 4、4'、5'和 8 位上具有取代位,可增强与病原体核酸的结合。本发明描述了更高的
补骨脂素结合
水平和更低的诱变性,从而更安全、更有效、更可靠地灭活血液制品中的病原体。本发明考虑使用新型
补骨脂素制备基本上不含核酸的非致突变性血液制品以及上述血液制品的方法,这些方法不会损害输血用血液制品的功能。
