  • Patent number: 6534503
    Abstract: Methods for treating sexual dysfunction, such as erectile dysfunction or sexual arousal disorder, with a compound having the generic formula X1—X2-(D)Phe-Arg-(D)Trp-X3. A particularly useful compound is HP-228, which has the formula Ac-Nle-Gln-His-(D)Phe-Arg-(D)Trp-Gly-NH2. The invention also provides methods for selecting melanocortin receptor-3 ligands by determining whether a compound modulates the activity of MC-3 as an agonist or antagonist. These methods can be used to screen compound libraries for ligands to treat MC-3-associated conditions. Such conditions include sexual dysfunction, including erectile dysfunction and sexual arousal disorder.

  • Publication number: 20020082193
    Abstract: The invention provides compositions and methods for altering insulin secretion using an agent that inhibits calcium efflux via the mitochondrial calcium/sodium antiporter (MCA). Methods of treatment are thereby provided, and are particularly useful for treatment of subjects having, or suspected of being at risk for having, diabetes mellitus. Compositions and methods related to the identification of gene sequences encoding the mitochondrial calcium/sodium antiporter, expression of such sequences and screening assays using expressed MCA products are also provided.

  • Patent number: 5877278
    Abstract: A solid-phase method for the synthesis of N-substituted oligomers, such as poly (N-substituted glycines) (referred to herein as poly NSGs) is used to obtain oligomers, such as poly NSGs of potential therapeutic interest which poly NSGs can have a wide variety of side-chain substituents. Each N-substituted glycine monomer is assembled from two "sub-monomers" directly on the solid support. Each cycle of monomer addition consists of two steps: (1) acylation of a secondary amine bound to the support with an acylating agent comprising a leaving group capable of nucleophilic displacement by --NH.sub.2, such as a haloacetic acid, and (2) introduction of the side-chain by nucleophilic displacement of the leaving group, such as halogen (as a solid support-bound .alpha.-haloacetamide) with a sufficient amount of a second sub-monomer comprising an --NH.sub.2 group, such as a primary amine, alkoxyamine, semicarbazide, acyl hydrazide, carbazate or the like.
