摘要:
The present invention relates to a cationic lipid having one or more biodegradable groups located in the mid- or distal section of a lipidic moiety (e.g., a hydrophobic chain) of the cationic lipid. These cationic lipids may be incorporated into a lipid particle for delivering an active agent, such as a nucleic acid. The invention also relates to lipid particles comprising a neutral lipid, a lipid capable of reducing aggregation, a cationic lipid of the present invention, and optionally, a sterol. The lipid particle may further include a therapeutic agent such as a nucleic acid.

摘要:
As a novel technique, which gives selective photoligation in high yield and enables ligated site-specific photocleavage, as well as free and reversible control of photoligation and photocleavage, a reversible photoligating nucleic acid of the following formula (1): is used to control photoligation and photocleavage to and from biofunctional polymers freely.
