  • Patent number: 6410505
    Abstract: A class of predominantly hydrophilic 1,8-naphthalimide dyes. The dye contains at least two 1,8-naphthalimide ring systems, joined by a spacer moiety. Each of the 1,8-naphthalimide ring system has a ring nitrogen atom and bears, at the 4 position, an amino nitrogen atom, carrying a hydrogen. The remaining unsatisfied valences, if present, of the ring nitrogen atoms or the amino nitrogen atoms, or all, are occupied by one or more alkyl substituents. Each of the 1,8-naphthalimide ring system is free of an azo substituent and is also free of a nucleofuge. Upon activation by an activating agent in an environment independent of the presence or absence of oxygen, these compounds generate activated species. The activated species can cause structural changes in lipid and any associated proteins and polypeptides, extra- or intra-cellular or transmembrane, leading to polymerization and crosslinking.

  • Patent number: RE37729
    Abstract: Heteroarylpiperidines, pyrrolidines, and piperazines are useful as antipsychotic and analgesic agents. The compounds are especially useful for treating psychoses by administering to a mammal a psychoses-treating effective amount of one of the compounds. Depot derivatives of the compounds are useful for providing long acting effects of the compounds. The compounds are also useful as analgesics by administering a pain-relieving effective amount of one of the compounds to a mammal.
