Cationic amphiphiles are being studied for their potential role in preparing liposomes for interaction with artificial and biological membranes and cellular transfection techniques. Cationic species with ester linkages to the hydrophobic portion are more easily degraded by recipient cells and more efficiently metabolized. | [Description]
DODAP (18:1) is an ionizable cationic lipid with lower cytotoxicity and high transfection efficiency. DODAP is neutral at physiological pH, but acquires a positive charge inside the endosome due to the protonation of free amines when pH is lower than its pKa (<7). | [in vivo]
In vitro potency of DODAP (100 μg/mL, i.v., i.m., 4h) strongly predicts in vivo potency for intramuscular administration but not for intravascular administration in female Balb/c mice[1]. | Animal Model: | female Balb/c mice[1] | | Dosage: | 100 μg/mL | | Administration: | Intravenous injection (i.v.), Intramuscular injection (i.m.),4 h | | Result: | Treatment resulted that a less negatively charged DODAP was more efficient in vitro and in vivo intramuscular injection, while for Intravenous injection administration, a more negative DODAP that was passively targeted through Apo-E absorption was more efficient for hepatocyte targeting. |
