  Several nitrosoureidonucleosides (9a, 9b, 11a, 11b, 18 and 20) designed as inhibitors of enzymes that metabolize purine and pyrimidine nucleotides have been prepared and their chemical and biological properties studied. The low level of biological activity observed may be due to the unexpected stability of these nitrosoureas compared to biologically active compounds such as N-methyl-N-nitrosourea (MNU), N,N'-bis(2-chloroethyl)-N'-nitrosourea (BCNU), and N,N'-dicyclohexyl-N-nitrosourea (DCyNU).

  An ambient-temperature self-curable fluorine containing aqueous-based polyurethane dispersion, a method of manufacturing the same and its modified coated film applications are provided. The ambient-temperature self-curable fluorine containing aqueous-based PU dispersion includes water, an ambient temperature cross-linking agent and a fluorine containing PU resin dispersed in water phase. The fluorine containing PU resin includes A includes octa-fluoropentanol, hexafluoroisopropanol, trifluoroethanol, tetrafluoropropanol or trifluoroethylamine. Treated fabric with the self-cured fluorine containing aqueous-based PU resin and it becomes a long-lasting water-repellent and stain-proof.
