Summary for Patent: 5,738,864
Title: Drug delivery agents incorporating mitomycin
Abstract:A conjugate of a carrier polymer and aziridine ring containing mitomycin (MMC) drug molecules is prepared by coupling the MMC molecules via their aziridine imino groups to spacer groups that terminate in protected amino groups, deprotecting said amino groups, recovering and purifying the spacer-MMC derivatives, and then coupling these derivatives via said deprotected amino groups to the carrier polymer. Alternatively, the MMC may first be treated with an activating agent, e.g. carbodiimidazole, to form an activated MMC derivative which is then coupled directly to spacer groups linked to the carrier polymer.
