Abstract
Cholic acid and galactose or lactose dual conjugated chitosan derivatives were designed and synthesized as potential anti liver cancer drug carriers, their structures were characterized through proton NMR spectra, elemental analysis, size distribution, zeta potential, and scanning electron microscope image studies. The ability of the dual conjugates to enhance the aqueous solubility of the cancer drug sorafenib was evaluated. The entrapment efficiency (EE%) and drug content (DC%) of sorafenib in the inclusion complexes were measured. The chitosan dual conjugate with cholic acid and galactose was found to be best in enhancing the aqueous solubility of sorafenib. The solubility of sorafenib in water has increased from 1.7 µg/mL to 1900 µg/mL which is equal to 1117-fold increase in its solubility due to the inclusion complex with chitosan conjugate.
