Dimethyl Sulfoxide → Paclitaxel

Participants

Reaction Steps

A coated stent from Example 9 is dipped into a DESMODUR solution (50:50 mixture of dimethylsulfoxide and tetrahydrofuran). The device is then removed and the coating is then partially dried at room temperature for 3 to 5 minutes. The device is then immersed in a beaker of water (room temperature) for 3-5 minutes to cause the polymerization reaction to occur rapidly. An echogenic coating is formed. In addition to 9-deoxotaxol, the following are exemplary compounds that may be used to coat the device: 7-deoxy-9-deoxotaxol and 10-desacetoxy-7-deoxy-9-deoxotaxol.
