This invention provides methods of modifying feeding behavior, including increasing or decreasing food consumption, e.g., in connection with treating obesity, bulimia or anorexia. These methods involve administration of compounds are selective agonists or antagonists or the Y5 receptor. One such compound has the structure:
In addition, this invention provides an isolated nucleic acid molecule encoding a Y5 receptor, an isolated Y5 receptor protein, vectors comprising an isolated nucleic acid molecule encoding a Y5 receptor, cells comprising such vectors, antibodies directed to the Y5 receptor, nucleic acid probes useful for detecting nucleic acid encoding Y5 receptors, antisense oligonucleotides complementary to any unique sequences of a nucleic acid molecule which encodes a Y5 receptor, and nonhuman transgenic animals which express DNA a normal or a mutant Y5 receptor.
本发明提供了修改进食行为的方法,包括增加或减少食物摄入量,例如与治疗肥胖症、暴食症或厌食症有关。这些方法涉及到给予选择性Y5受体的激动剂或拮抗剂化合物。其中一种化合物具有以下结构:此外,本发明提供了编码Y5受体的分离核酸分子、分离的Y5受体蛋白、包含编码Y5受体的分离核酸分子的载体、含有这样的载体的细胞、针对Y5受体的
抗体、用于检测编码Y5受体的核酸探针、与编码Y5受体的任何独特序列互补的反义寡核苷酸,以及表达正常或突变Y5受体的非人类转
基因动物。
