Abstract:
There are disclosed certain novel compounds identified as benzo-fused lactams which promote the release of growth hormone in humans and animals. This property can be utilized to promote the growth of food animals to render the production of edible meat products more efficient, and in humans, to increase the stature of those afflicted with a lack of a normal secretion of natural growth hormone. Growth promoting compositions containing such benzo-fused lactams as the active ingredient thereof are also disclosed.

Description:
BACKGROUND OF THE INVENTION 
     Growth hormone, which is secreted from the pituitary, stimulates growth of all tissues of the body that are capable of growing. In addition, growth hormone is known to have the following basic effects on the metabolic process of the body: 
     1. Increased rate of protein synthesis in all cells of the body; 
     2. Decreased rate of carbohydrate utilization in cells of the body; 
     3. Increased mobilization of free fatty acids and use of fatty acids for energy. 
     A deficiency in growth hormone secretion can result in various medical disorders, such as dwarfism. 
     Various ways are known to release growth hormone. For example, chemicals such as arginine, L-3,4-dihydroxyphenylalanine (L-DOPA), glucagon, vasopressin, and insulin induced hypoglycemia, as well as activities such as sleep and exercise, indirectly cause growth hormone to be released from the pituitary by acting in some fashion on the hypothalamus perhaps either to decrease somatostatin secretion or to increase the secretion of the known secretagogue growth hormone releasing factor (GRF) or an unknown endogenous growth hormone-releasing hormone or all of these. 
     In cases where increased levels of growth hormone were desired, the problem was generally solved by providing exogenous growth hormone or by administering an agent which stimulated growth hormone production and/or release. In either case the peptidyl nature of the compound necessitated that it be administered by injection. Initially the source of growth hormone was the extraction of the pituitary glands of cadavers. This resulted in a very expensive product and carried with it the risk that a disease associated with the source of the pituitary gland could be transmitted to the recipient of the growth hormone. Recently, recombinant growth hormone has become available which, while no longer carrying any risk of disease transmission, is still a very expensive product which must be given by injection or by a nasal spray. 
     Other compounds have been developed which stimulate the release of endogenous growth hormone such as analogous peptidyl compounds related to GRF or the peptides of U.S. Pat. No. 4,411,890. These peptides, while considerably smaller than growth hormones are still susceptible to various proteases. As with most peptides, their potential for oral bioavailability is low. The instant compounds are non-peptidyl agents for promoting the release of growth hormone which may be administered parenterally, nasally or by the oral route. 
     SUMMARY OF THE INVENTION 
     The instant invention covers certain benzo-fused lactam compounds which have the ability to stimulate the release of natural or endogenous growth hormone. The compounds thus have the ability to be used to treat conditions which require the stimulation of growth hormone production or secretion such as in humans with a deficiency of natural growth hormone or in animals used for food production where the stimulation of growth hormone will result in a larger, more productive animal. Thus, it is an object of the instant invention to describe the benzo-fused lactam compounds. It is a further object of this invention to describe procedures for the preparation of such compounds. A still further object is to describe the use of such compounds to increase the secretion of growth hormone in humans and animals. A still further object of this invention is to describe compositions containing the benzo-fused lactam compounds for the use of treating humans and animals so as to increase the level of growth hormone secretions. Further objects will become apparent from a reading of the following description.

     The compounds of the instant invention all have at least one asymmetric center as noted by the asterisk in the structural Formula I above. Additional asymmetric centers may be present on the molecule depending upon the nature of the various substituents on the molecule. Each such asymmetric center will produce two optical isomers and it is intended that all such optical isomers, as separated, pure or partially purified optical isomers or racemic mixtures thereof, be included within the ambit of the instant invention. In the case of the asymmetric center represented by the asterisk in Formula I, it has been found that the compound in which the 3-amino substituent is above the plane of the structure, as seen in Formula Ia, is more active and thus more preferred over the compound in which the 3-amino substituent is below the plane of the structure. In the substituent (X) n , when n=0, the asymmetric center is designated as the R-isomer. When n=1, this center will be designated according to the R/S rules as either R or S depending upon the value of X. ##STR12## 
     The instant compounds are generally isolated in the form of their pharmaceutically acceptable acid addition salts, such as the salts derived from using inorganic and organic acids. Examples of such acids are hydrochloric, nitric, sulfuric, phosphoric, formic, acetic, trifluoroacetic, propionic, maleic, succinic, malonic and the like. In addition, certain compounds containing an acidic function such as a carboxy can be isolated in the form of their inorganic salt in which the counterion can be selected from sodium, potassium, lithium, calcium, magnesium and the like, as well as from organic bases. 
     The compounds (I) of the present invention are prepared from intermediates such as those of formula H. The preparation of these intermediates is described in the following reaction Schemes. ##STR13## 
     Compounds of formula H are prepared by alkylation of intermediates of formula III as shown in Scheme 1. The preparation of compounds of formula III has been previously described by Fisher, et al, U.S. Pat. No. 5,206,235 and references cited therein. Alkylation of intermediates of formula III is conveniently carried out in anhydrous dimethyl formamide (DMF) in the presence of bases such as sodium hydride or potassium t-butoxide for a period of 0.5 to 24 hours at temperatures of 20°-100° C., with an alkylating agent IV, wherein Y is a good leaving group such as Cl, Br, I, O-methanesulfonyl or O-(p-toluenesulfonyl). Separation of unwanted side products, and purification of products is achieved by chromatography on silica gel, employing flash chromatography (W. C. Still, M. Kahn and A. Mitra, J. Org. Chem., 43, 2923(1978)) or by medium pressure liquid chromatography. Substituents on the alkylating agent IV may need to be protected during alkylation. A description of such protecting groups may be found in: Protective Groups in Organic Synthesis, T. W. Greene, John Wiley and Sons, New York, 1981. ##STR14## 
     Compounds of formula II wherein R 3a  is taken as --SO 2  NR 4a  R 12a  are prepared from the sulfonyl chloride 1 as shown in Scheme 2. Reaction of 1 with the secondary amine R 4a  R 12a  NH in an inert solvent such as methylene chloride in the presence of a base, such as triethylamine or 4-dimethylaminopyridine, gives the sulfonamide product 2. Reaction of 2 with compounds of formula III is carried out using the conditions described in Scheme 1. ##STR15## 
     As shown in Scheme 3, an analogous series of transformations is employed to assemble compounds of formula II wherein R 3a  is defined as --SO 2  N(R 12b )NR 4a  R 12a  (5). ##STR16## 
     Reaction of sulfonyl chloride 1 with the secondary amine t-BuN(R 12b )H and subsequent alkylation with III by the aforementioned procedures, leads to intermediate 7 (Scheme 4). ##STR17## 
     A useful synthesis of intermediate 12 is outlined in Scheme 5. Reaction of o-bromobenzenesulfonyl chloride 8 with t-butylamine in methylene chloride gives the t-butyl sulfonamide 9 in high yield. Reaction of 9 with 4-methylphenyltrimethylstannane 10 in the presence of bis(triphenylphosphine)palladium(II) chloride in dimethylformamide at elevated temperature gives the coupled product 11 in good yield. Conversion to bromide 12 is achieved by free radical bromination with N-bromosuccinimide in carbon tetrachloride in the presence of the radical initiator, azobisisobutyronitrile (AIBN). Reaction of 12 with compounds of formula III is carried out using the conditions described in Scheme 1. ##STR18## 
     Intermediate 7 may be converted to a new intermediate 13 by removal of the t-butyl group. As shown in Scheme 6, treatment of 7 with a strong acid, such as hydrochloric acid in methanol or trifluoroacetic acid in methylene chloride, results in loss of the t-butyl group to give the product. It may be appreciated by one skilled in the art that the protecting group G in 7 must therefore be compatible with the strongly acidic conditions employed; hence G is taken as benzyloxycarbonyl. ##STR19## 
     Acylsulfonamide compounds of-formula II (14) are prepared from intermediate 13 as indicated in Scheme 7. Acylation of 13 is carried out by treatment with reaction with the activated acyl imidazolide intermediate derived from R 5a  COOH and N,N&#39;-carbonyldiimidazole. 
     Alternatively, the acylsulfonamide product 14 is obtained by reaction of 13 with the acid chloride, R 5a  COCl. ##STR20## 
     Intermediate 13 is also converted into N-carbamoyl and N-alkoxycarbonyl sulfonamides. Reaction of 13 with substituted carbamoyl chloride reagent 15 in an inert solvent such as methylene chloride in the presence of a triethylamine or 4-dimethylaminopyridine affords the N-carbamoyl sulfonamide product 16 as shown in Scheme 8. ##STR21## 
     An analogous sequence is employed in the synthesis of N-thiocarbamoyl sulfonamide 18 using the thiocarbamoyl reagent 17 as outlined in Scheme 9. ##STR22## 
     As illustrated in Scheme 10, reaction of 13 with an isocyanate reagent 19 also gives an N-carbamoyl sulfonamide product 20 wherein R 4a  is hydrogen. The corresponding N-thiocarbamoyl sulfonamide analog of 20 can also be obtained by reaction of 13 with an appropriate isothiocyanate. ##STR23## 
     N-Alkoxycarbonyl sulfonamides 22 are also prepared from 13 by reaction with a chloroformate (or equivalent) reagent 21 as shown in Scheme 11. ##STR24## 
     Substituted hydrazide compounds of formula II (23) are prepared from intermediate 13 by a two-step sequence consisting of treatment of the hydrazine compound R 4a  R 12a  NN(R 12b )H with N,N&#39;-carbonyldiimidazole, followed by reaction of the active species thus formed with intermediate 13 (Scheme 12). ##STR25## 
     The corresponding thio analog of 23 can be obtained from 13 by the aforementioned procedure by substituting N,N&#39;-thiocarbonyldiimidazole for N,N&#39;-carbonyldiimidazole. 
     Conversion to the final products of formula I wherein R 4  is hydrogen, is carried out by simultaneous or sequential removal of all protecting groups from intermediate II as illustrated in Scheme 13. ##STR26## 
     Removal of benzyloxycarbonyl (CBz) groups can be achieved by a number of methods known in the art; for example, catalytic hydrogenation with hydrogen in the presence of a platinum or palladium catalyst in a protic solvent such as methanol. In cases where catalytic hydrogenation is contraindicated by the presence of other potentially reactive functionality, removal of benzyloxycarbonyl groups can also be achieved by treatment with a solution of hydrogen bromide in acetic acid. Removal of t-butoxycarbonyl (BOC) protecting groups is carried out by treatment of a solution in a solvent such as methylene chloride or methanol, with a strong acid, such as hydrochloric acid or trifluoroacetic acid. Conditions required to remove other protecting groups which may be present can be found in Protective Groups in Organic Synthesis T. W. Greene, John Wiley and Sons, N.Y. 1981. 
     As shown in Scheme 14, compounds of formula I wherein R 4  and R 5  are each hydrogen can be further elaborated to new compounds which are substituted on the amino group. Reductive alkylation with an aldehyde is carried out under conditions known in the art; for example, by catalytic hydrogenation with hydrogen in the presence of platinum, palladium or nickel catalysts or with chemical reducing agents such as sodium cyanoborohydride in an inert solvent such as methanol or ethanol. Substitution on the amine can also be achieved by reaction with various epoxides. The products, obtained as hydrochloride or trifluoroacetate salts, are conveniently purified by reverse phase high performance liquid chromatography (HPLC) or by recrystallization. ##STR27## 
     It is noted that the order of carrying out the foregoing reaction schemes is not significant and it is within the skill of one skilled in the art to vary the order of reactions to facilitate the reaction or to avoid unwanted reaction products. 
     The growth hormone releasing compounds of Formula I are useful in vitro as unique tools for understanding how growth hormone secretion is regulated at the pituitary level. This includes use in the evaluation of many factors thought or known to influence growth hormone secretion such as age, sex, nutritional factors, glucose, amino acids, fatty acids, as well as fasting and non-fasting states. In addition, the compounds of this invention can be used in the evaluation of how other hormones modify growth hormone releasing activity. For example, it has already been established that somatostatin inhibits growth hormone release. Other hormones that are important and in need of study as to their effect on growth hormone release include the gonadal hormones, e.g., testosterone, estradiol, and progesterone; the adrenal hormones, e.g., cortisol and other corticoids, epinephrine and norepinephrine; the pancreatic and gastrointestinal hormones, e.g., insulin, glucagon, gastrin, secretin; the vasoactive intestinal peptides, e.g., bombesin; and the thyroid hormones, e.g., thyroxine and triiodothyronine. The compounds of Formula I can also be employed to investigate the possible negative or positive feedback effects of some of the pituitary hormones, e.g., growth hormone and endorphin peptides, on the pituitary to modify growth hormone release. Of particular scientific importance is the use of these compounds to elucidate the subcellular mechanisms mediating the release of growth hormone. 
     The compounds of Formula I can be administered to animals, including man, to release growth hormone in vivo. For example, the compounds can be administered to commercially important animals such as swine, cattle, sheep and the like to accelerate and increase their rate and extent of growth, and to increase milk production in such animals. In addition, these compounds can be administered to humans in vivo as a diagnostic tool to directly determine whether the pituitary is capable of releasing growth hormone. For example, the compounds of Formula I can be administered in vivo to children. Serum samples taken before and after such administration can be assayed for growth hormone. Comparison of the amounts of growth hormone in each of these samples would be a means for directly determining the ability of the patient&#39;s pituitary to release growth hormone. 
     Accordingly, the present invention includes 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 active ingredient of the pharmaceutical compositions can comprise a growth promoting agent in addition to at least one of the compounds of Formula I or another composition which exhibits a different activity, e.g., an antibiotic or other pharmaceutically active material. 
     Growth promoting agents include, but are not limited to, TRH, diethylstilbesterol, theophylline, enkephalins, E series prostaglandins, compounds disclosed in U.S. Pat. No. 3,239,345, e.g., zeranol, and compounds disclosed in U.S. Pat. No. 4,036,979, e.g., sulbenox or peptides disclosed in U.S. Pat. No. 4,411,890. 
     A still further use of the disclosed novel benzo-fused lactam growth hormone secretagogues is in combination with other growth hormone secretagogues such as GHRP-6, GHRP-1 or GHRP-2 as described in U.S. Pat. Nos. 4,411,890; and publications WO 89/07110, WO 89/07111 and WO 93/04081 or B-HT 920 or in combination with growth hormone releasing factor and its analogs or growth hormone and its analogs. A still further use of the disclosed novel benzo-fused lactam growth hormone secretagogues is in combination with α 2  adrenergic agonists or β 3  adrenergic agonists in the treatment of obesity or in combination with parathyroid hormone or bisphosphonates, such as MK-217 (alendronate), in the treatment of osteoporosis. A still further use of the disclosed novel benzo-fused lactam growth hormone secretagogues is in combination with IGF-1 to reverse the catabolic effects of nitrogen wasting as described by Kupfer, et al, J. Clin. Invest., 91, 391 (1993). 
     As is well known to those skilled in the art, the known and potential uses of growth hormone are varied and multitudinous. Thus, the administration of the compounds of this invention for purposes of stimulating the release of endogenous growth hormone can have the same effects or uses as growth hormone itself. These varied uses of growth hormone may be summarized as follows: stimulating growth hormone release in elderly humans; prevention of catabolic side effects of glucocorticoids; treatment of osteoporosis; stimulation of the immune system; treatment of retardation; acceleration of wound healing; accelerating bone fracture repair; treatment of growth retardation, treating renal failure or insufficiency resulting in growth retardation; treatment of physiological short stature, including growth hormone deficient children; treating short stature associated with chronic illness; treatment of obesity and growth retardation associated with obesity; treating growth retardation associated with Prader-Willi syndrome and Turner&#39;s syndrome; accelerating the recovery and reducing hospitalization of burn patients; treatment of intrauterine growth retardation, skeletal dysplasia, hypercortisolism and Cushings syndrome; induction of pulsatile growth hormone release; replacement of growth hormone in stressed patients; treatment of osteochondrodysplasias, Noonans syndrome, schizophrenia, depression, Alzheimer&#39;s disease, delayed wound healing, and psychosocial deprivation; treatment of pulmonary dysfunction and ventilator dependency; attenuation of protein catabolic response after a major operation; 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 hemeostasis in the frail elderly; stimulation of osteoblasts, bone remodelling, and cartilage growth; stimulation of the immune system in companion animals and treatment of disorders of aging in companion animals; growth promotant in livestock and stimulation of wool growth in sheep. 
     The compounds of this invention can be administered by oral, parenteral (e.g., intramuscular, intraperitoneal, intravenous or subcutaneous injection or implant), nasal, vaginal, rectal, sublingual, or topical routes of administration and can be formulated in dosage forms appropriate for each route of administration. 
     Solid dosage forms for oral administration include capsules, tablets, pills, powders and granules. In such solid dosage forms, the active compound is admixed with at least one inert pharmaceutically acceptable carrier such as sucrose, lactose, or starch. Such dosage forms can also comprise, as is normal practice, additional substances other than inert diluents, e.g., lubricating agents such as magnesium stearate. In the case of capsules, tablets and pills, the dosage forms may also comprise buffering agents. Tablets and pills can additionally be prepared with enteric coatings. 
     Liquid dosage forms for oral administration include pharmaceutically acceptable emulsions, solutions, suspensions, syrups, the elixirs containing inert diluents commonly used in the art, such as water. Besides such inert diluents, compositions can also include adjuvants, such as wetting agents, emulsifying and suspending agents, and sweetening, flavoring and perfuming agents. 
     Preparations according to this invention for parenteral administration include sterile aqueous or non-aqueous solutions, suspensions, or emulsions. Examples of non-aqueous solvents or vehicles are propylene glycol, polyethylene glycol, vegetable oils, such as olive oil and corn oil, gelatin, and injectable organic esters such as ethyl oleate. Such dosage forms may also contain adjuvants such as preserving, wetting, emulsifying, and dispersing agents. They may be sterilized by, for example, filtration through a bacteria-retaining filter, by incorporating sterilizing agents into the compositions, by irradiating the compositions, or by heating the compositions. They can also be manufactured in the form of sterile solid compositions which can be dissolved in sterile water, or some other sterile injectable medium immediately before use. 
     Compositions for rectal or vaginal administration are preferably suppositories which may contain, in addition to the active substance, excipients such as cocoa butter or a suppository wax. 
     Compositions for nasal or sublingual administration are also prepared with standard excipients well known in the art. 
     The dosage of active ingredient in the compositions of this invention may be varied; however, it is necessary that the amount of the active ingredient be such that a suitable dosage form is obtained. The selected dosage depends upon the desired therapeutic effect, on the route of administration, and on the duration of the treatment. Generally, dosage levels of between 0.0001 to 100 mg/Kg of body weight daily are administered to patients and animals, e.g., mammals, to obtain effective release of growth hormone.
