The invention relates to flavin-NAL conjugates and to their applications in the field of genetic engineering. Depending on the nature of the flavin which is conjugated to the NAL, the conjugates according to the invention can be used either (1) as nucleases for specifically and efficiently cleaving target nucleic acid sequences in living cells, or (2) as carriers for specifically and efficiently addressing NALs, such as for example antisense oligonucleotides, inside the cells.
该发明涉及黄素-NAL共轭物及其在遗传工程领域中的应用。根据与NAL共轭的黄素的性质,根据本发明的共轭物可以用作(1)在活细胞中特异和高效地切割靶核酸序列的
核酸酶,或者(2)用作特异和高效地将NAL(例如反义寡核苷酸)引入细胞内的载体。
