General description

Carboxylic acids are readily soluble in polar solvents such as water and alcohols. DSPE-PEG(2000) carboxylic acid consists of a hydrophilic polyethylene glycol (PEG) chain of 2kDa.

Application

DSPE-PEG(2000) carboxylic acid has been used:
  • to covalently conjugate integrin α-2 (ITGA2) antibodies to the surface of the liposomes
  • in the preparation of atosiban-conjugated liposomes
  • to prepare dual complementary liposome

Biochem/physiol Actions

DSPE-PEG(2000) carboxylic acid increases the blood circulation time of liposomes. The carboxyl group of DSPE-PEG(2000) carboxylic acid aids in covalent conjugation with antibodies.

Hepatotoxicity is a key concern in the clinical translation of nanotherapeutics because preclinical studies have consistently shown that nanotherapeutics accumulates extensively in the liver. However, clinical-stage nanotherapeutics have not shown increased hepatotoxicity. Factors that can contribute to the hepatotoxicity of
