  6-Acylamino-2-aminoquinolines as Potent Melanin-Concentrating Hormone 1 Receptor Antagonists. Identification, Structure−Activity Relationship, and Investigation of Binding Mode

  摘要：

  Novel 6-acylamino-2-aminoquinoline melanin-concentrating hormone 1 receptor (MCHIR) antagonists were identified by sequential in silico screening with 3D pharmacophore models derived from a series of benzamide antagonists. The structure- activity relationship exploration by synthesis of analogues found structural demands around the western part of the compounds to be quite specific, whereas much structural freedom was found in the eastern part. Vvhile these compounds in general suffered from poor solubility properties, the 4-trifluoromethoxy-phenoxyacetamide western appendage provided a favorable combination of activity and solubility properties. The amine in the eastern appendage, originally required by the pharmacophore model and believed to interact with Asp123 in transmembrane 3 of MCH1R, could be removed without diminishing affinity or functional activity of the compounds. Docking studies suggested that the Asp123 interacts preferentially with the nitrogen of the central quinoline. Synthesis and testing of specific analogues supported our revised binding mode hypothesis.

  The present invention relates to the use of quinoline compounds for the preparation of a pharmaceutical and/or a cosmetic composition for the treatment, prophylaxis and/or diagnosis of a condition caused by or involving a melanin-concentrating hormone. The invention also relates to novel quinoline compounds per se. The quinoline compounds have been found to interact with a melanin-concentrating hormone receptor, a MCH receptor. The compounds have modulating activity on the MCH receptor such as e.g. antagonistic, agonistic or allosteric activity and are useful for medicinal or cosmetic purposes such as, e.g. in the treatment or prevention of feeding disorders like obesity, metabolic syndrome, Type II diabetes, bulimia, etc. or in the treatment or prevention of depression.

  本发明涉及使用喹啉化合物制备用于治疗、预防和/或诊断由或涉及黑色素浓缩激素引起的疾病的药物和/或化妆品组合物。本发明还涉及新型喹啉化合物本身。已发现喹啉化合物与黑色素浓缩激素受体（MCH受体）相互作用。该化合物对MCH受体具有调节活性，例如拮抗、激动或异构活性，并可用于药用或化妆品用途，例如治疗或预防饮食障碍，如肥胖症、代谢综合征、2型糖尿病、贪食症等，或治疗或预防抑郁症。
