This invention is directed to compounds of the formula ##STR1## and the pharmaceutically-acceptable salts thereof, where the substituents are as defined in the Specification, which are growth hormone secretogogues and which increase the level of endogenous growth hormone. The compounds of this invention are useful for the treatment and prevention of osteoporosis, congestive heart failure, frailty associated with aging, obesity; accelerating bone fracture repair, attenuating protein catabolic response after a major operation, reducing cachexia and protein loss due to chronic illness, accelerating wound healing, or accelerating the recovery of burn patients or patients having undergone major surgery; improving muscle strength, mobility, maintanence of skin thickness, metabolic homeostasis or renal homeostasis. The compounds of the present invention are also useful in treating osteoporosis when used in combination with: a bisphosphonate compound such as alendronate; estrogen, premarin, and optionally progesterone; an estrogen agonist or antagonist; or calcitonin, and pharmaceutical compositions useful therefor. Further, the present invention is directed to pharmaceutical compositions useful for increasing the endogenous production or release of growth hormone in a human or other animal which comprises an effective amount of a compound of the present invention and a growth hormone secretagogue selected from GHRP-6, Hexarelin, GHRP-1, growth hormone releasing factor (GRF), IGF-1, IGF-2 or B-HT920. The invention is also directed to intermediates useful in the preparation of compounds of formula I.
本发明涉及公式##STR1##的化合物及其药学上可接受的盐,其中取代基如规范中所定义,它们是生长激素分泌素,可以增加内源性生长激素的水平。本发明的化合物对于骨质疏松症、充血性心力衰竭、与老龄化相关的虚弱、肥胖症;加速骨折修复、减轻重大手术后的蛋白质分解反应、减轻慢性疾病引起的消瘦和蛋白质流失、加速伤口愈合或加速烧伤患者或接受重大手术的患者的康复;改善肌肉力量、机动性、皮肤厚度、代谢稳态或肾脏稳态具有用途。本发明的化合物在与双磷酸盐类化合物(如阿伦膦酸盐)、雌激素、孕激素和选择性雌激素受体调节剂或拮抗剂、降钙素一起使用时,对于治疗骨质疏松症也具有用途,以及用于此用途的药物组合物。此外,本发明还涉及用于增加人类或其他动物内源性生长激素产生或释放的药物组合物,该组合物包括本发明的化合物的有效量和选择自GHRP-6、Hexarelin、GHRP-1、生长激素释放因子(GRF)、IGF-1、IGF-2或B-HT920的生长激素分泌素。本发明还涉及用于制备公式I化合物的中间体。
