Novel cationic amphiphiles are provided that facilitate transport of biologically active (therapeutic) molecules into cells. By this invention, such cationic amphiphile is used in a state in which it is capable of accepting additional protons, i.e., it is not fully protonated. For purposes of this invention, cationic amphiphiles may be considered to encompass four general categories: (A) T-shaped/steroid-based amphiphiles; (B) T-shaped/non steroid-based amphiphiles; (C) non T-shaped/steroid based amphiphiles and (D) non T-shaped/non steroid-based amphiphiles.
提供了新型阳离子两性分子,可促进
生物活性(治疗)分子进入细胞。通过这项发明,这种阳离子两性分子在能够接受额外质子的状态下使用,即它没有完全质子化。为了这项发明的目的,阳离子两性分子可以被认为包括四个一般类别:(A)T形/类
固醇基两性分子;(B)T形/非类
固醇基两性分子;(C)非T形/类
固醇基两性分子和(D)非T形/非类
固醇基两性分子。
