in the hydrophobic chains of the lipids through the preparation of five new amphiphiles. The amphiphiles and corresponding lipoplexes were characterized by DSC, TEM, and X-ray, as well as evaluated for DNA binding and DNA transfection. For one specific charge-reversal lipid, stable lipoplexes of approximately 550 nm were formed, and with this amphiphile, effective in vitro DNA transfection activities
合成了一系列具有不同链长和末端功能的电荷反转脂质。这些脂质被设计成结合 DNA,然后根据与 DNA 的静电相互作用的变化释放 DNA。具体而言,可裂解的酯键位于烃链的末端。通过制备五种新的两亲物,通过改变脂类疏水链中酯键的长度和位置来调整从两亲物释放的 DNA。两亲物和相应的脂质复合物通过 DSC、TEM 和 X 射线进行表征,并评估 DNA 结合和 DNA 转染。对于一种特定的电荷反转脂质,形成了大约 550 nm 的稳定脂质复合物,并且使用这种两亲物,在体外有效 观察DNA转染活性。
