摘要："PASylation, which was recently reported as the conjugation of pharmacologically active compounds with polypeptide sequences mainly made of proline, alanine and serine, has been proposed as an alternative to PEGylation. In this study, we designed PAS-modified liposomes (PASylated liposomes) and studied the effect of the incorporation of PAS-lipid on the stability and pharmacokinetic properties of liposomes, and compared them both in vitro and in vivo to PEGylated liposomes. Results showed that PASylated liposomes modified with single-chained PAS-lipid C16-(PA3)7 (SC-PAS-Lip) showed comparable storage and serum stability to PEGylated liposomes (PEG-Lip), and a significantly decreased macrophage uptake compared with unmodified liposomes. SC-PAS-Lip displayed long circulating pharmacokinetic profile which was not impacted by the repeated administration of liposomes, and they were less likely to induce the production of anti-PEG IgM compared with PEGylated liposomes, presenting PASylation as an alternative liposome modification strategy to PEGylation.
