| Abstract |
Recent studies have focused on the active targeting of drug delivery by combining a homing device and antitumor drug. For this purpose, synthesis of a well-designed vehicle (such as polymer/drug conjugates or nanoparticles) carrying a drug and a homing device requires many steps. We propose a new type of drug delivery system (DDS) by formation of a complex containing avidin (Av) plus biotinyl drug with a biotinyl homing device, which easily accommodates the combination of various drugs and homing devices. The targetable drug complex can be prepared by selecting an appropriate biotinyl drug derivative and a biotinyl homing device and mixing them with avidin. Fluorescent dye with 5-(and-6)-carboxytetramethylrhodamine (TAMRA) was used as a drug model, and galactose (Gal) recognized by liver parenchymal cells was used as a homing device. TAMRA and galactose were attached to biotin (Bio) through a triethyleneglycol (TEG) spacer group to give Bio-TEG-TAMRA conjugate and Bio-TEG-Gal conjugate, respectively. Confocal laser scanning microscopic studies suggest that the complexes prepared by mixing Bio-TEG-Gal conjugate and fluorescein isothiocyanate (FITC)-labeled Av (feed molar ratio 4:1), and mixing Bio-TEG-Gal conjugate, Bio-TEG-TAMRA conjugate and FITC-labeled Av are internalized into the hepatoma cells through a receptor-mediated endocytosis mechanism. |
