Abstract
The present invention relates to a conjugate of ginsenoside compound K and glycol chitosan, a method for preparing the conjugate, and a pharmaceutical composition for treating cancer including the conjugate in a pharmaceutically acceptable carrier. The conjugate of ginsenoside compound K and glycol chitosan of the present invention has cancer cell-specific anticancer activity because of increased water solubility relative to ginsenoside compound K, formation of nanosized self-aggregates in an aqueous solution, stability at neutral pH and release of the ginsenoside compound K at acidic pH due to pH sensitivity, thus having excellent effects as a composition for treating cancer.
