Isolated polynucleotides encoding monkey and canine Melanin Concentrating Hormone (MCH) Type 2 receptors and chimeric polypeptides are provided. Vectors and cells for recombinant expression of such MCH receptor polypeptides, and isolated MCH receptor polypeptides are also provided. MCH receptor polynucleotides and polypeptides may be used, for example, to identify agents that specifically interact with MCH receptor. Such agents find use within therapies for humans and animals afflicted with conditions associated with MCH receptor activation.

Monkey and canine melanin concentrating hormone receptors

Isolated polynucleotides encoding monkey Melanin Concentrating Hormone (MCH) Type 1 receptors and chimeric polypeptides are provided. Vectors and cells for recombinant expression of such MCH1R polypeptides, and isolated MCH1R polypeptides are also provided. MCH1R polynucleotides and polypeptides may be used, for example, to identify compounds that specifically interact with MCH receptor. Such compounds find use within therapies for humans and animals afflicted with conditions associated with MCH receptor activation.

Melanin concentrating hormone receptors

This invention relates to low molecular weight, non-peptidic, non-peptidomimetic, organic molecules that act as modulators of mammalian complement C5a receptors, preferably ones that act as high affinity C5a receptor ligands and also to such ligands that act as antagonists or inverse agonists of complement C5a receptors. Preferred compounds of the invention possess some or all of the following properties in that they are: 1) multi-aryl in structure, 2) heteroaryl in structure, 3) a pharmaceutically acceptable oral dose can provide a detectable in vitro effect, 4) comprise fewer than four or preferably no amide bonds, and 5) capable of inhibiting leukocyte chemotaxis at nanomolar or sub-nanomolar concentrations. This invention also relates to pharmaceutical compositions comprising such compounds and the use of such compounds in treating a variety of inflammatory and immune system disorders. Additionally, this invention relates to the use such compounds as probes for the localization of C5a receptors.

High affinity small molecule C5a receptor modulators

This invention provides novel human capsaicin receptors and the nucleotide sequences encoding these receptors. Also provided are vectors encoding these receptors and mammalian and non-mammalian cells expressing these vectors. Further provided are assays for identifying compounds that modulate capsaicin receptors and diagnostic assays for capsaicin receptor polymorphisms and aberrant capsaicin receptor expression.

Human capsaicin receptor and uses thereof

Capsaicin receptor ligands

This invention relates to low molecular weight, non-peptidic, non-peptidomimetic, organic molecules that act as modulators of mammalian complement C5a receptors, preferably ones that act as high affinity C5a receptor ligands and also to such ligands that act as antagonists or inverse agonists of complement C5a receptors, preferably human C5a receptors, Preferred compounds of the invention possess one or more, and preferably two or more, three or more, four or more, or all of the following properties in that they are; 1) multi-aryl in structure (having a plurality of un-fused or fused aryl groups), 2) heteroaryl in structure, 3) orally available in vivo (such that a sub-lethal or preferably a pharmaceutically acceptable oral dose can provide a detectable in vitro effect such as a reduction of C5a-induced neutropenia), 4) comprised of fewer than four, preferably fewer than three, or fewer than two, or no amide bonds, and 5) capable of inhibiting leukocyte chemotaxis at nanomolar concentrations and preferably at sub-nanomolar concentrations. Specifically exemplified representative compounds include, but are not limited to optionally substituted arylimidazoles, optionally substituted arylpyridyls, optionally substituted aryl-substituted cycloalkylimidazoles, optionally substituted arylpyrazoles, optionally substituted benzimidazoles, optionally substituted aryl-substituted tetrahydroisoquinolines, and optionally substituted biaryl carboxamides. This invention also relates to pharmaceutical compositions comprising such compounds. It further relates to the use of such compounds in treating a variety of inflammatory and immune system disorders. Additionally, this invention relates to the use such compounds as probes for the localization of C5a receptors.
