  • 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: 6316437
    Abstract: Spirohydantoin compounds and their pharmaceutically acceptable salts are disclosed. The synthesis of these compounds and their use as alpha 1a adrenergic receptor antagonists is also described. One application of these compounds is in the treatment of benign prostatic hyperplasia. These compounds are typically selective in their ability to relax smooth muscle tissue enriched in the alpha 1a receptor subtype without at the same time inducing hypotension. One such tissue is found surrounding the urethral lining. Therefore, one utility of the instant compounds is to provide acute relief to males suffering from benign prostatic hyperplasia, by permitting less hindered urine flow. Another utility of the instant compounds is provided by combination with a human 5-alpha reductase inhibitory compound, such that both acute and chronic relief from the effects of benign prostatic hyperplasia can be achieved.

  • Patent number: 6046333
    Abstract: The present invention is directed to a novel convergent process for the preparation of the compound N-[1(R)-[(1,2-dihydro-1-methanesulfonyl-spiro[3H-indole-3,4'-piperdin]-1'- yl)carbonyl]-2-(phenylmethyl-oxy)ethyl]-2-amino-2-methyl-propanamide, and salts thereof, which has the structure: ##STR1## and which has the ability to stimulate the release of natural or endogenous growth hormone. This compound may be used to treat conditions which require the stimulation of growth hormone production or secretion such as in humans with a deficiency of natural growth hormone or in animals used for food or wool production where the stimulation of growth hormone will result in a larger, more productive animal.

  • Patent number: 6002000
    Abstract: Methods are disclosed for determining an analyte in a medium suspected of containing the analyte. One method comprises providing (1) combining a medium suspected of containing the analyte and a novel chemiluminescent compound, (2) combining a means for chemically activating the chemiluminescent compound; and (3) detecting the amount of luminescence generated by the chemiluminescent compound. The amount of luminescence generated is related to the amount of analyte in the medium. The chemiluminescent compound can be chemically activated by hydrogen peroxide. Compositions and kits are also disclosed.
