  • Patent number: 6482825
    Abstract: This invention provides compounds of formula I and pharmaceutically-acceptable salts thereof, where the substituents are defined in the specification, which are growth hormone secretogogues useful for 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, maintenance of skin thickness, metabolic homeostatis or renal homeostasis. Compounds of formula I in combination with: a bisphosphonate such as alendronate; estrogen, estrogens, and optionally progesterone; an estrogen agonist or antagonist; or calcitonin, and pharmaceutical compositions thereof are useful in treating osteoporosis.
