Amphiphilic polyether branched molecules to increase the circulation time of cationic particles
摘要:
The preparation, physicochemical and biological properties of amphiphilic polyether branched molecules is described. These 'bunch shaped' molecules when inserted into cationic liposomes/DNA complexes have shown efficient surface charge shielding. As a consequence they efficiently inhibited the non specific interactions with blood components and significantly enhanced circulation time of the particles in the blood track. Formulations containing these molecules compared positively with those containing PEG lipids, providing a 5-fold increase in circulation time. (c) 2007 Elsevier Ltd. All rights reserved.

The convergent synthesis and surface modification of a novel family of aliphaticpolyether dendrons is described. The synthesis utilizes methallyl dichloride as the monomeric building block along with peripheral benzyl ether and ketal protected hydroxy functionalities. The allylic nature of the electrophilic moieties of methallyl dichloride facilitates their nucleophilic displacement by 2 equiv of
