The present invention provides a method of treating obesity, sexual dysfunction (including erectile dysfunction), diabetes, insulin resistance, hyperinsulinemia, Syndrome X, adrenal dysfunction, hypertension, hypercholesterolemia, atherosclerosis, hyperlipoproteinemia, hypertriglyceridemia, or substance abuse, the method comprising the step of administering to a patent having or at risk of having one of the above-mentioned diseases a therapeutically effective amount of a compound that attenuates the binding of agouti-related protein to melanocortin receptors, but does not attenuate the binding of α-melanocyte stimulating hormone to melanocortin receptors. The present invention also provides a method of identifying a compound that is useful for the treatment or prevention of obesity, sexual dysfunction (including erectile dysfunction), diabetes, insulin resistance, hyperinsulinemia, Syndrome X, adrenal dysfunction, hypertension, hypercholesterolemia, atherosclerosis, hyperlipoproteinemia, hypertriglyceridemia, or substance abuse, the method comprising the steps of: 1) determining if a compound affects the binding of agouti-related protein to melanocortin receptors; 2) determining if a compound affects the binding of α-melanocyte stimulating hormone to melanocortin receptors; and 3) selecting a compound that attenuates the binding of agouti-related protein to melanocortin receptors, but does not affect the binding of α-melanocyte stimulating hormone to melanocortin receptors.
本发明提供了一种治疗肥胖、性功能障碍(包括勃起功能障碍)、糖尿病、胰岛素抵抗、高胰岛素血症、X综合征、肾上腺功能障碍、高血压、高胆固醇血症、动脉粥样硬化、高脂蛋白血症、高甘油三酯血症或药物滥用的方法、该方法包括以下步骤:向患有或有可能患有上述疾病之一的专利人施用治疗有效量的化合物,该化合物能减弱激动相关蛋白与黑皮素受体的结合,但不能减弱α-黑素细胞刺激素与黑皮素受体的结合。本发明还提供了一种鉴定化合物的方法,该化合物可用于治疗或预防肥胖、性功能障碍(包括勃起功能障碍)、糖尿病、胰岛素抵抗、高胰岛素血症、X综合征、肾上腺功能障碍、高血压、高胆固醇血症、动脉粥样硬化、高脂蛋白血症、高甘油三酯血症或药物滥用,该方法包括以下步骤:1)确定一种化合物是否会影响激动相关蛋白与黑色素皮质受体的结合;2)确定一种化合物是否会影响α-促黑色素细胞激素与黑色素皮质受体的结合;以及3)选择一种能减弱激动相关蛋白与黑色素皮质受体的结合,但不影响α-促黑色素细胞激素与黑色素皮质受体的结合的化合物。
