  • Publication number: 20160022764
    Abstract: The present invention relates to an ionic complex comprising a cationic polypeptide and an anionic excipient selected from: a PEG-carboxylic acid; a fatty acid having 10 or more carbon atoms; an anionic phospholipid; and a combination thereof. The invention also relates to a pharmaceutical composition comprising the ionic complex of the invention and a pharmaceutically acceptable carrier. The cationic polypeptide of the ionic complex has pharmacological activity and the complex can provide a more desirable pharmacokinetic profile for the cationic polypeptide of the complex as compared to the cationic polypeptide alone following administration. As such, the invention also relates to the use of the ionic complex and pharmaceutical composition comprising same to treat a subject suffering from a disease or disorder that is responsive to the cationic polypeptide of the ionic complex.

  • Patent number: 7321074
    Abstract: Cells and non-human transgenic animals have been engineered to be deficient in the gene encoding the melcanocortin-3 receptor protein (MC-3R). MC-3R deficient transgenic animals have increased fatmass and reduced lean body mass, showing that the MC-3R protein is involved in the regulation of body fat and muscle mass. These MC-3R deficient transgenic animals can be used to select for and test potential modulators of MC-3R. This data allows for methods of screening for MC-3R modulators which effect body weight and associated methods of treating various disorders associated with inappropriate regulation of body weight. The disclosure also relates to a MC-3R/MC-4R double knockout mouse which can be used to select for and test potential modulators (e.g., agonists or antagonists) of MC-3R and/or MC-4R. It is shown that MC-3R serves a non-redundant role, when compared to MC-4R, in the regulation of energy homeostasis.
