Creation of Pure Nanodrugs and Their Anticancer Properties

A method for preparing nanoparticles of a water-insoluble drug that are suitable for administration to the human body has been established. A reprecipitation method was used to fabricate 50 nm nanoparticles of dimerized SN-38, an anticancer camptothecin derivative, that form stable aqueous dispersions and can penetrate into cancer cells to inhibit cell proliferation more potently than irinotecan.
