  Novel synthetic LPDs consisting of different cholesterol derivatives for gene transfer into hepatocytes

  摘要：

  In the present study, LPDs composing of a series of novel synthetic cholesterylated derivatives bearing a cluster of galactose residues and different spacer lengths were prepared for performing target gene delivery to hepatocytes and their physiochemical properties as well as gene transfer efficiency were investigated. In agreement with the "clustering effect" known to occur with more complex oligomeric structures, the addition of galactose residues under optimized spatial arrangement condition invariably increased the transfect efficiency into hepatoma cells, which can be owed to the sufficient binding of galactose ligands to the ASGPR on hepatocytes. However, the gene transfer ability to hepatocytes was not always improved with extended spacer arms, suggesting a spatial binding sites arrangement of the receptor. Moreover, our research has established galactosylated LPDs, specifically, LPDIIb, LPDIIIc, and LPDIVe as potential vectors to deliver special genes into hepatocytes with low toxicity, combining the condensing effect of protamine and the targeting capability of cholesterylated thiogalactosides.

  Synthesis of Cholesterylated Thiogalactosides for Gene Delivery

  摘要：

  A series of cholesterylated thiogalactosides L-1 - L-6 the cell targeting ligands for gene delivery to hepatocytes, was synthesized. Related poly( ethylene glycol) chain was used as a bridge for the attachment of galactoside on one hydroxyl end, while the other hydroxyl end was linked with cholesterol. This design provided an effective entry for the synthesis of a poly( ethylene glycol) compound with the hepatocyte targeting.

  A novel sulfhydryl-β-D-glucose cholesterol 10a-10f as ligand for brain targeting liposomes was designed and synthesized. 10e was applied to the preparation of liposomal delivery system for achieving the brain-targeted delivery of the model drug tegafur in mice utilizing the glucose transporter member 1 (GLUT1). The results suggest the feasibility to enhance liposomes ability of delivering drug to brain by using the designed compound as liposome ligands.

  A series of glucose cholesterol derivatives 8a-8e as ligands for brain targeting liposomes were synthesized. The preparation of compound 6 involved temporary protection of glucose with chlorotrimethylsilicane and hexamethyldisilazane followed by selectively hydrolyzed. The known cholesteryl tosylate 1 were coupled to ethylene glycols to afford alcohol 2a-2e. Substitution and deprotection of alcohol 2a-2e furnished the acids 4a-4e, which was condensed with compound 6 to get compounds 7a-7e, and then was deprotected in tetrahydrofuran with TFA to obtain the title compounds. As a model drug, tegafur was entrapped by liposomes coupled with 8b, and preliminary in vivo evaluation shown 8b could enhance the ability of liposomes delivering tegafur across the blood brain barrier.
