Abstract:
PURPOSE: A water soluble anticancer agent and a method for manufacturing the same are provided to overcome low water solubility. CONSTITUTION: A method for preparing a water soluble anticancer agent comprises: a step of removing sodium salt from low molecular weight heparin; a step of introducing amine groups to docetaxel; a step of mixing the heparin and docetaxel; and a step of purifying the self-aggregated heparin-docetaxel assembly. The molar ratio of the heparin and docetaxel is 1:1-10.
Abstract:
The present invention relates to a water-soluble anticancer drug composed of a heparin-docetaxel conjugate and to a method for preparing the same and, more specifically, to a water-soluble anticancer drug in which a spherical nanoparticle is formed of a conjugate having aminized docetaxel self-aggregated on low-molecular weight heparin, and a hydrophilic segment of the heparin is introduced on a surface of the nanoparticle, and to a method for preparing the water-soluble anticancer drug, comprising the steps of removing a sodium salt from low-molecular heparin; introducing an amine group to docetaxel; mixing the sodium salt-removed heparin and the docetaxel with the introduced amine group to self-aggregate the mixture; and purifying the self-aggregated heparin-docetaxel conjugate. According to the present invention, provided can be a water-soluble anticancer drug capable of overcoming the low solubility of docetaxel in water, improving the administrability of heparin, and expecting a synergy effect of simultaneously applying anticancer activity of docetaxel and anticancer activity of heparin.
Abstract:
PURPOSE: A water soluble anticancer agent containing heparin-docetaxel-taurocholic acid conjugate and a method for preparing the same are provided to create hydrophilic environment on the surface of a micelle structure and to ensure bioavailability. CONSTITUTION: A targeting water soluble anticancer agent has a spherical nanoparticles comprising docetaxel in a core and taurocholic acid on the surface. The molecular weight of the heparin is 3000-5000 da. A method for manufacturing the anticancer agent comprises: a step of removing sodium salt of low molecular heparin; a step of introducing amine groups to the docetaxel; a step of introducing amine groups to taurocholic acid; a step of mixing the heparin, docetaxel, and taurocholic acid for self-aggregation; and a step of purifying the self-aggregated heparin-docetaxel-taurocholic acid assembly.
