Conjugated bile acid oligomer to a New vesicular Transport and use of the same

摘要

1. A method for preparing oligomeric macromolecule-oligomeric isomers of cholic acid at a specific terminal includes: (a) preparing an oligomeric isomer of cholic acid by oligomerization of two or more monoisomers of cholic acid; and (b) combining an oligomeric isomer of acetic acid. 1. The macromolecule is a polymer, which is symmetrical to the terminal position of macromolecule in stage (a).
