Cationic polysaccharide derivatives are prepared by reacting a polysaccharide with a polycationic reagent having one polysaccharide reactive group and at least two cationic groups. Suitable reagents include polycationic alkyl, aryl, alkaryl, cycloaliphatic, or heterocyclic amines, some of which are novel compositions. The polycationic polysaccharide derivatives prepared from these reagents are useful in the manufacture of paper.

many pharmacologicalproperties including antiinflammatory and immunosuppressive actions. However, their use over long periods is hampered by a number of severe side effects. Given the biological properties of nitric oxide (NO) and previous experience with nonsteroidal antiinflammatory agents, we synthesized new chemical entities combining both NO and GC properties. Here we report the synthesis of nitro
