GL67 (N4-Spermine cholesteryl carbamate) is a cationic lipid widely utilized for the delivery of nucleic acid agents, vaccines, and gene transfection due to its efficient carrier properties. At equal molar concentrations, the salt and free forms of a compound typically demonstrate similar biological activity. However, the salt form often offers superior water solubility and improved stability, making it more practical for various applications.
