Compositions for transporting a bioactive agent across a biological membrane include the bioactive agent, an oil, an oil-immiscible compound and a noncationic surface active agent. The compositions may deliver the bioactive agent through a chemical microporulation mechanism, which allows transfer of the agent across both cellular, intracellular organelle, and nuclear membranes. Compositions for nucleic acid delivery include nucleic acid, oil, oil-immiscible compound, noncationic surface active agent and essentially no cationic lipid, or include nucleic acid, oil, oil-immiscible compound and two noncationic surface active agents. The nucleic acid may be hydrophobically-modified, and be in combination with an oil, an oil-immiscible compound and at least one surface active agent. The compositions may be used for gene delivery to a cell, as well as delivery of other therapeutic agents.
用于跨生物膜传输生物活性剂的组合物包括生物活性剂、油、油不溶性化合物和非阳离子表面活性剂。这些组合物可通过化学微孔机制输送生物活性剂,从而实现生物活性剂在细胞膜、细胞内细胞器和核膜上的转移。用于递送核酸的组合物包括核酸、油、油不溶性化合物、非阳离子表面活性剂和基本不含阳离子的脂质,或包括核酸、油、油不溶性化合物和两种非阳离子表面活性剂。核酸可进行疏水改性,并与油、油不混溶化合物和至少一种表面活性剂结合使用。这些组合物可用于向细胞输送基因,也可用于输送其他治疗剂。
