The present invention provides recombinant expression constructs comprising nucleic acid encoding mammalian melanocortin receptors, and mammalian cells into which said recombinant expression constructs have been introduced that express functional mammalian melanocortin receptors. The invention provides a panel of such transformed mammalian cells expressing melanocortin receptors for screening compounds for receptor agonist and antagonist activity. The invention also provides methods for using such panels of melanocortin receptor-expressing mammalian cells to specifically-detect and identify agonists and antagonists for each melanocortin receptor, as well as patterns of agonist and antagonist activity of said compounds for the class of melanocortin receptors. Such screening methods provide a means for identifying compounds with patterns of melanocortin agonist and antagonist activity which is associated with the capacity to influence or modify metabolism and behavior, particularly feeding behavior.

Certain novel 4-substituted N-acylated piperidine derivatives are agonists of the human melanocortin receptor(s) and, in particular, are selective agonists of the human melanocortin-4 receptor (MC-4R). They are therefore useful for the treatment, control, or prevention of diseases and disorders responsive to the activation of MC-4R, such as obesity, diabetes, sexual dysfunction, including erectile dysfunction and female sexual dysfunction.

Peptides cyclized via disulfide or lactam bridges are disclosed. The peptides exhibit melanocortin-4 receptor agonist activity and are useful for treating obesity.

Disclosed are novel ligands based on an AGRP template that can rescue endogenous melanocortin agonist and/or antagonist dysfunction at MCR polymorphisms. In particular, the present invention provides novel synthetic ligands based on AGRP templates that can rescue endogenous melanocortin agonist dysfunction at MC4R polymorphisms to treat children and adults with these mutations and increase their quality of life.

The present invention relates to peptide ligands of the melanocortin receptors, in particular the melancortin-4 receptor, and as such, are useful in the treatment of dyslipidemia and associated complications such as alcoholic and non-alcoholic fatty liver disease.

The present invention relates to a novel process for the synthesis of the melanocortin analog, Ac-Arg-cyclo(Cys-D-Ala-His-D-Phe-Arg-Trp-Cys)-NH₂, using solution-phase peptide chemistry.

Described herein is the use of Agouti Signaling Protein (ASIP), in addition to certain other melanocortin signaling network (MSN) genes, as prognostic and predictive biomarkers for the progression of breast cancer. In particular, the novel biomarkers can be used to determine if a female breast cancer patient is at risk of progressing to metastatic disease and thus also be used to direct treatment of the patient.

The invention relates to an application of ML00253764 in preparation of a medicine for treating obesity due to melanocortin receptors-4 mutant. The compound ML00253764 is taken as the medicine for treating obesity due to melanocortin receptors-4 mutant.
