METHODS AND COMPOSITIONS FOR DELIVERY OF ACTIVE AGENTS

摘要

A lipid particle can include a cationic lipid. The cationic lipid can include one or more hydrophobic tails, which can include one or more sites of unsaturation. The sites of unstaturation can include cycloalkyl groups, e.g., cyclopropyl, cyclobutyl, cyclopentyl, or cyclohexyl groups. The lipid particle is suitable for delivering an active agent.
