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 inactivation methods using the new psoralens which do not compromise the function of blood products for transfusion.
合成了带有取代基的苯麻
酚化合物,这些取代基位于苯麻
酚的4、4'、5'和8位,使其能够更好地结合病原体的核酸。描述了更高的苯麻
酚结合
水平和更低的致突变性,从而在血液制品中更安全、更高效、更可靠地灭活病原体。该发明考虑了使用新苯麻
酚进行灭活的方法,这些方法不会损害用于输血的血液制品的功能。
