Growth hormone secretagogues

What is disclosed are growth hormone secretagogues, and their uses, of the formula wherein R1 is C6H5CH2OCH2—, C6H5(CH2)3— or indol-3-ylmethyl; Y is pyrrolidin-1-yl, 4-C1-C6alkylpiperidin-1-yl or NR2R2; R2 are each independently a C1to C6alkyl; R3 is 2-napthyl or phenyl para-substituted by W; W is H, F, CF3, C1-C6alkoxy or phenyl; and R4 is H or CH3, or a pharmaceutically acceptable salt or solvate thereof.

STEREOSELECTIVE PROCESS FOR THE SYNTHESIS OF (D)-2-AMINO-5-PHENYLPENTANOIC OR ALKYL ESTER THEREOF

The present invention provides a process for preparing a compound of formula (I); wherein R is a C1-C6 alkyl; or a salt thereof; comprising:(c) hydrolyzing (D,L)-N-acetyl-2-amino-5-phenylpentanoic acid with a suitable base in the pre

Treatment of insulin resistance with growth hormone secretagogues

This invention is directed to methods of treating insulin resistance in a mammal which comprise administering an effective amount of a compound of formula I, where the variables are defined in the specification, or the stereoisomeric mixtures, diastereomerically enriched, diastereomerically pure, enantiomerically enriched or enantiomerically pure isomers, or the pharmaceutically acceptable salts and prodrugs thereof to said mammal. The compounds of formula I are growth hormone secretagogues and as such are useful for increasing the level of endogenous growth hormone. In another aspect this invention provides certain intermediates which are useful in the synthesis of the foregoing compounds and certain processes useful for the synthesis of said intermediates and the compounds of formula I. This invention is further directed to methods comprising administering to a human or other animal a combination of a functional somatostatin antagonist such as an alpha-2 adrenergic agonist and a compound of formula I.

Dipeptide derivatives as growth hormone secretagogues

This invention is directed to compounds of the formula 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 and/or frailty, 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 homeostasis or renal homeostasis. The compounds of the present invention are also useful in treating osteoporosis and/or frailty 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.

Synthesis and biological activities of phenyl piperazine- based peptidomimetic growth hormone secretagogues

A new class of potent, orally active phenyl piperazine-based GH secretagogues have been discovered from attempts to mimic the arrangement of the phenyl substitutent in the spiroindanyl piperidine and spiroindoline sulfonamide privileged structures of 4 and 1, respectively. The best of these compounds, 18 (EC50 = 2.8 nM) is nearly as potent as MK-0677 for releasing GH from rat pituitary cells.
