retard the DNA mobiliy at concentrations of 30, 30, 10, and 20 μM, respectively. Reversible DNA release in O-1 and O-2 complexes can be achieved in the presence of heparin sodium, whereas the presence of GSH greatly improved DNA release in D-1 and D-2 complexes. The particles formed were in a size range of 50-170 nm with positively charged surfaces. D-1 and D-2 transfected pEGFP-N1 into HeLa cells successfully
具有氢键键序列DADDAD和胍(O-1)或1,5,9-三氮杂环十二烷([12] aneN3; O-2)侧链的寡酰胺分子链和具有氢键键序列ADAADA和辛基部分(O- 3),合成。通过序列特异性的氢键缔合和交联的二硫键将亲水性O-1或O-2和疏水性O-3偶联,制备了两个双链体(D-1和D-2)。电泳测量表明,O-1,O-2,D-1和D-2能够分别分别以30、30、10和20μM的浓度完全延迟DNA的迁移。在肝素钠存在下,可实现O-1和O-2复合物中DNA的可逆释放,而GSH的存在可大大改善D-1和D-2复合物中DNA的释放。所形成的颗粒的尺寸范围为50-170 nm,表面带正电。D-1和D-2成功地将pEGFP-N1转染到HeLa细胞中。
