Compounds with growth hormone releasing properties

Description

FIELD OF INVENTION
The present invention relates to novel compounds, compositions containing them, and their use for treating medical disorders resulting from a deficiency in growth hormone.
BACKGROUND OF THE INVENTION
Growth hormone is a hormone which stimulates growth of all tissues capable of growing. In addition, growth hormone is known to have a number of effects on metabolic processes, e.g., stimulation of protein synthesis and free fatty acid mobilization and to cause a switch in energy metabolism from carbohydrate to fatty acid metabolism. Deficiency in growth hormone can result in a number of severe medical disorders, e.g., dwarfism.
Growth hormone is released from the pituitary. The release is under tight control of a number of hormones and neurotransmitters either directly or indirectly. Growth hormone release can be stimulated by growth hormone releasing hormone (GHRH) and inhibited by somatostatin. In both cases the hormones are released from the hypothalamus but their action is mediated primarily via specific receptors located in the pituitary. Other compounds which stimulate the release of growth hormone from the pituitary have also been described. For example arginine, L-3,4-dihydroxyphenylalanine (L-Dopa), glucagon, vasopressin, PACAP (pituitary adenylyl cyclase activating peptide), muscarinic receptor agonists and a synthethic hexapeptide, GHRP (growth hormone releasing peptide) release endogenous growth hormone either by a direct effect on the pituitary or by affecting the release of GHRH and/or somatostatin from the hypothalamus.
In disorders or conditions where increased levels of growth hormone is desired, the protein nature of growth hormone makes anything but parenteral administration non-viable. Furthermore, other directly acting natural secretagogues, e.g., GHRH and PACAP, are longer polypeptides for which reason oral administration of them is not viable.
The use of certain compounds for increasing the levels of growth hormone in mammals has previously been proposed, e.g. in EP 18 072, EP 83 864, WO 89/07110, WO 89/01711, WO 89/10933, WO 88/9780, WO 83/02272, WO 91/18016, WO 92/01711, WO 93/04081, WO 95/17422, WO 95/17423 and WO 95/14666.
The composition of growth hormone releasing compounds is important for their growth hormone releasing potency as well as their bioavailability. It is therefore an object of the present invention to provide novel compounds with growth hormone releasing properties.

We have discovered that the rat and human GHRH receptor display different structure activity relations for the human GHRH (hGHRH) peptide. We have designed a series of truncated analogs of hGHRH. The analogs activates the GHRH receptor, but does not have the disadvantages of GHRH. An advantage of these truncated analogs is their improved metabolic stability. Further the truncated analogs may offer advantages with respect to prolonged or modified duration of action, decreased immunogenicity, selectivity/side effects and lower cost of production.

Generally, the compounds of the present invention are dispensed in unit dosage form comprising 50-200 mg of active ingredient together with a pharmaceutically acceptable carrier per unit dosage.
The dosage of the compounds according to this invention is suitably 0.1-500 mg/day, e.g. from about 5 to about 50 mg, such as about 10 mg per dose, when administered to patients, e.g. humans, as a drug.
It has been demonstrated that compounds of the general formula I possess the ability to release endogenous growth hormone in vivo. The compounds may therefore be used in the treatment of conditions which require increased plasma growth hormone levels such as in growth hormone deficient humans or in elderly patients or livestock.
Thus, in a particular aspect, the present invention relates to a pharmaceutical composition for stimulating the release of growth hormone from the pituitary, the composition comprising, as an active ingredient, a compound of the general formula I or a pharmaceutically acceptable salt thereof together with a pharmaceutically acceptable carrier or diluent.
In a further aspect, the present invention relates to a method of stimulating the release of growth hormone from the pituitary, the method comprising administering to a subject in need thereof an effective amount of a compound of the general formula I or a pharmaceutically acceptable salt thereof.
In a still further aspect, the present invention relates to the use of a compound of the general formula I or a pharmaceutically acceptable salt thereof for the preparation of a medicament for stimulating the release of growth hormone from the pituitary.
To those skilled in the art, it is well known that the current and potential uses of growth hormone in humans are varied and multitudinous. Thus, compounds of formula I can be administered for purposes stimulating release of growth hormone from the pituitary and would then have similar effects or uses as growth hormone itself. The uses of growth hormone may be summarized as follows: stimulation of growth hormone release in the elderly; prevention of catabolic side effects of glucocorticoids, prevention and treatment of osteoporosis, stimulation of the immune system, acceleration of wound healing, accelerating bone fracture repair, treatment of growth retardation, treating renal failure or insufficiency resulting from growth retardation, treatment of physiological short stature including growth hormone deficient children and short stature associated with chronic illness, treatment of obesity and growth retardation associated with obesity, treating growth retardation associated with the Prader-Willi syndrome and Turner's syndrome; accelerating the recovery and reducing hospitalization of burn patients; treatment of intrauterine growth retardation, skeletal dysplasia, hypercortisolism and Cushing's syndrome; induction of pulsatile growth hormone release; replacement of growth hormone in stressed patients, treatment of osteochondrodysplasias, Noonan's syndrome, schizophrenia, depressions, Alzheimer's disease, delayed wound healing and psychosocial deprivation, treatment of pulmonary dysfunction and ventilator dependency, attenuation of protein catabolic responses after major surgery, reducing cachexia and protein loss due to chronic illness such as cancer or AIDS; treatment of hyperinsulinemia including nesidioblastosis, adjuvant treatment for ovulation induction; to stimulate thymic development and prevent the age-related decline of thymic function, treatment of immunosuppressed patients, improvement in muscle strength, mobility, maintenance of skin thickness, metabolic homeostasis, renal homeostasis in the frail elderly, stimulation of osteoblasts, bone remodelling and cartilage growth, stimulation of the immune system in companion animals and treatment of disorder of aging in companion animals, growth promoter in livestock and stimulation of wool growth in sheep.
For the above indications the dosage will vary depending on the compound of formula I employed, on the mode of administration and on the therapy desired. However, generally dosage levels between 0.0001 and 100 mg/kg body weight daily are administered to patients and animals to obtain effective release of endogenous growth hormone. Usually, dosage forms suitable for oral, nasal, pulmonal or transdermal administration comprise from about 0.0001 mg to about 100 mg, preferably from about 0.001 mg to about 50 mg of the compounds of formula I admixed with a pharmaceutically acceptable carrier or diluent.
Optionally, the pharmaceutical composition of the invention may comprise a compound of formula I combined with one or more compounds exhibiting a different activity, e.g., an antibiotic or other pharmacologically active material.
The route of administration may be any route which effectively transports the active compound to the appropriate or desired site of action, such as oral, nasal, pulmonary, transdermal or parenteral, the oral route being preferred.
Apart from the pharmaceutical use of the growth hormone releasing hormones of formula I, they may be useful in vitro tools for investigating the regulation of growth hormone release.
The compounds of Formula I are also useful in vivo tools for evaluating the growth hormone releasing capability of the pituitary. For example, serum samples taken before and after administration of these compounds to humans can be assayed for growth hormone. Comparison of the growth hormone in each serum sample would directly determine the ability of the patients pituitary to release growth hormone.
The compounds of Formula I can be administered to commercially important animals to increase their rate and extent of growth, and to increase milk production.
Accordingly, the present invention include within its scope pharmaceutical compositions comprising, as an active ingredient, at least one of the compounds of Formula I in association with a pharmaceutical carrier or diluent. Optionally, the pharmaceutical composition can comprise at least one of the compounds of Formula I combined with compounds exhibiting a different activity, e.g., an antibiotic or other pharmacologically active material.
A further use of the compounds of Formula I is in combination with other secretagogues like GHRP's, such as GHRP (2 or 6), growth hormone and its analogues or somatomedins including IGF-1 and IGF-2.
For the above indications, dosage will vary depending on the compound of Formula I employed, on the mode of administration and on the therapy desired. However, generally dose levels between 0.0001 to 100 mg/kg body weight daily are administered to patients and animals to obtain effective release of endogenous growth hormone.
The route of administration may be any route which affectively transports the active compound to the appropriate or desired site of action, such as oral or parenteral, the oral route being the preferred.
Any novel feature or combination of features described herein is considered essential to this invention.
Pharmacological Methods

EXAMPLES
Compounds of Formula I were evaluated in vitro for their efficacy and potency to stimulate the human GHRH receptor in cell lines stably expressing this receptor. Briefly, 80% confluent cells were scraped off and pelleted at 10,000.times.g for 10 min at 4.degree. C.
1. For binding assay the cell pellet was homogenized in 10 mM Tris-acetate buffer (pH 7.4) and centrifuged at 50,000.times.g for 10 min at 4C. The pellet were rehomogenized in the same buffer and diluted to 200 ug membrane protein/ml. Assay consisted of 25 ul .sup.125 I-GHRH(1-29)NH.sub.2 (200,000 cpm/tube), 900 ul Tris-acetate buffer and 25 ul 0.2% Tween 20. This mixture was incubated for 45 min at room temperature. The reaction was terminated by rapid filtration through GF/B filters pre-wetted with 0.5% PEI.
2. For Adenylyl cyclase assay the cell pellet was processed and assay performed as described previously for Dopamine D1 receptors in Pedersen et al., Eur. J. Pharmacol. 267, 85-93, 1994.
3. Compounds of Formula I were evaluated in vitro for their efficacy and potency to release growth hormone in primary rat somatotrophs. Rat primary somatotrophs were prepared essentially as described previously (Chen et al., Endocrinology 129, 3337-3342, 1991 and Chen et al., Endocrinology, 124, 2791-2798, 1989). Briefly, rats were killed by decapitation. The pituitary were quickly removed. The pituitaries were digested with 0.2% collagenase n 0.2% hyaluronidase in Hanks balanced salt solution. The cells were resuspended in Dulbecco@s modified eagles medium containing 0.37% NaHCO.sub.2, 10% horse serum, 2.5% fetal calf serum, 1% nonessential amino acids, 1% glutamine and 1% pen/strep and adjusted to 1.5.times.10.sup.5 cells/ml. One ml of this suspension was placed in each well of 24-well trays and left for 2-3 days before release experiments were performed.
On the day of the experiments, cells were washed twice with the above medium containing 25 mM HEPES, pH 7.4. Growth hormone release were initiated by addition of medium containing 25 mM HEPES and test compound. Incubation was carried out for 15 min at 37.degree. C. After incubation growth hormone released to the medium was measured by a standard RIA assay.

Experimental Procedures
Method 1
Linear peptides were synthesized with an ABI 431A peptide synthesizer using standard protocols according to the Fmoc SPPS strategy (as substantially described by Fields et al., Int. J. Pept. Protein Res. 35, 1990, 161) on Rink amide polystyrene resin [4-((4',2'-dimethoxyphenyl)-(Fmoc-amino)methyl)-phenoxy resin, e.g. Novabiochem, Bad Soden, Germany, cat.#01-64-0013]. The peptides were cleaved from resin using standard cleavage cocktails containing a mixture of trifluoroactic acid and common scavengers (e.g., a mixture of trifluoroacetic acid (4 mL), phenol (300 mg), ethanedithiol (0.10 mL), thioanisole (0.20 mL) and water (0.20 mL), or as substantially described in the "novabiochem catalog and Peptide Synthesis Handbook" 94/95 on pages S34 to 336 and in references 1 to 15 listed on page S39). Subsequently, the cleavage mixture was concentrated to 1 mL using a stream of nitrogen, and the crude peptides were precipitated from this oil with diethyl ether (45 mL), washed with diethyl ether (3 portions of 50 mL) and dried.
Purifications were performed by semipreparative HPLC using a Sep-Pak C18 cartridge (Waters part.# 51910). All purified peptides were characterized by at least one analytical HPLC chromatogram on a Waters 510 system equipped with a Vydac C18 column (5 to 60% acetonitrile in water, 42.degree. C., 0.1 M ammonium sulfate, pH adjusted to 2.5 with 4 M sulfuric acid, 50 min) and plasma desorption mass spectroscopy.

Method 3
Cyclic peptides by sidechain to sidechain cyclization from an amino to a carboxy group were synthesized using 4-methylbenzhydryl (MBHA) polystyrene resin and an ABI 430 peptide synthesizer employing standard protocols according to the Boc SPPS strategy (e.g, as substantially described by Stewart and Young, Solid Phase Peptide Synthesis, 2nd ed., Rockford, Ill., USA, 1976). In general, sidechain functionalities intended for cyclization were protected using a base-labile protecting group (Fmoc-protection for amino groups, fluorenylmethylester-protection for carboxy groups, as described in T. W. Greene, P. G. M. Wuts, Protective Groups in Organic Synthesis, 2nd ed., J. Wiley & Sons, New York 1991, or in the "novabiochem catalog and Peptide Synthesis Handbook" 94/95 on pages S29 to S33 and in references 1 to 16 listed on page S33); other sidechain functionalities were protected using standard, hydrofluoric acid labile protecting groups suitable for Boc peptide synthesis (e.g., as described by Stewart and Young, Solid Phase Peptide Synthesis, 2nd ed., Rockford, Ill., USA, 1976). For cyclization of peptides via the sidechain functionality of lysine or ornithine, the amino group in the sidechain can be acylated with an Fmoc protected spacer amino acid (e.g., FmocGly); subsequently, the amino group of the spacer amino acid can be used for formation of the amide bond with the sidechain functionality of glutamic acid or aspartic acid. After formation of the cyclic structure and removal of the N-terminal Boc group, further synthesis and final cleavage are carried out under standard conditions for Boc SPPS strategy.
The crude peptide was dried and purified by HPLC on a 20 mm.times.250 mm column packed with 7.mu. C-18 silica which was preequilibrated with 15% CH.sub.3 CN in 0.05 M (NH.sub.4).sub.2 SO.sub.4, which was adjusted to pH 2.5 with 4 M H.sub.2 SO.sub.4. The crude peptide was dissolved in 2 mL 70% CH.sub.3 CN/0.1% TFA in H.sub.2 O and diluted to 100 mL with H.sub.2 O. This solution was divided into two equal portions and each of them were injected on the column in two separate runs. The column was eluted with a gradient of 15%-25% CH.sub.3 CN in 0.05 M (NH.sub.4).sub.2 SO.sub.4, pH 2.5 at 10 mL/min during 47 min at 40.degree. C. The peptide-containing fractions were collected, diluted with 3 volumes of H.sub.2 O and applied to a Sep-Pak.RTM. C18 cartrtidge (Waters part. #:51910) which was equilibrated with 0.1% TFA/H.sub.2 O. The peptide was eluted from the Sep-Pak.RTM. cartridge with 70% CH.sub.3 CN/0.1% TFA/H.sub.2 O and isolated from the eluate after dilution with water.
The final product obtained was characterized by analytical RP-HPLC (retention time) and by plasma desorption mass spectrometry (molecular mass). Mass spectrometry ageed with the expected structure within the experimental error of the method.
The RP-HPLC analysis was performed using UV-detection at 214 nm and a Vydac 218TP54 4.6 mm.times.250 mm 5.mu. C-18 silica column (the Separations Group, Hesperia) which was eluted at 1 mL/min at 42 .degree. C. Two different elution conditions were used:
A1: The column was equilibrated with 5% CH.sub.3 CN in a buffer consisting of 0.1 M (NH.sub.4).sub.2 SO.sub.4, which was adjusted to pH 2.5 with 4 M H.sub.2 SO.sub.4, and eluted with a gradient of 5% to 60% CH.sub.3 CN in the same buffer during 50 min.
B1: The column was equilibrated with 5% CH.sub.3 CN/0.1% TFA/H.sub.2 O and eluted by a gradient of 5% CH.sub.3 CN/0.1% TFA/H.sub.2 O to 60% CH.sub.3 CN/0.1% TFA/H.sub.2 O during 50 min.
