  • Publication number: 20050042674
    Abstract: The present invention provides common ligand mimics that act as common ligands for a receptor family. The present invention also provides bi-ligands containing these common ligand mimics. Bi-ligands of the invention provide enhanced affinity and/or selectivity of ligand binding to a receptor or receptor family through the synergistic action of the common ligand mimic and specificity ligand which compose the bi-ligand. The present invention also provides combinatorial libraries containing the common ligand mimics and bi-ligands of the invention. Further, the present invention provides methods for manufacturing the common ligand mimics and bi-ligands of the invention and methods for assaying the combinatorial libraries of the invention.

  • 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.
