Cationic Liposome Development

Cationic liposomes are the key components of liposome delivery systems. The heads of cationic lipids mostly contain amine groups ranging from simple amino groups to quaternary ammonium salts substituted with methyl or hydroxyethyl groups. The polar heads of cationic lipids play a role in the intercalation of liposomes with DNA, liposome-DNA complexes with cell membranes or other intracellular components. Among cationic cholesterol derivatives, cationic cholesterol compounds with tertiary amine groups have higher transfection viability and are much less toxic than quaternary ammonium salt compounds. Cationic liposomes with multivalent polar head groups or with multiple positively charged polar heads are more efficiently transfected, probably because of its stronger binding to DNA.

Cationic Liposome Development Services

Development of cationic liposomes requires a balance between delivery efficiency and cytotoxicity. The cytotoxicity of cationic liposomes depends on the structure of their hydrophilic head groups, e.g., amphiphiles containing quaternary ammonium head groups are more toxic than amphiphiles containing tertiary amines. CD Formulation offers solutions to address the cytotoxicity of cationic liposomes, helping them to better deliver active substances.
