Description

TETRAHYDROISOOUINOLINE DERIVATIVES AS LHRH ANTAGONISTS
Technical Field of the Invention The present invention relates to novel tetrahydroisoquinoline derivatives having activity as luteinizing hormone releasing hormone (LHRH) antagonists. In particular, the invention relates to pharmaceuticals containing these compounds, a process for making them, as well as a method for treating various hormone dependent diseases, including prostate cancer, endometriosis, uterine fibroids, precocious puberty, benign prostate hypertrophy, and in vitro fertilization.
Background of the Invention
The gonadotropin hormones, luteinizing hormone (LH) and follicle-stimulating hormone (FSH) regulate the fundamental reproductive processes, such as ovarian release and gamete maturation. LHRH released from the hypothalamus binds to a receptor on the pituitary gland causing the release of gonadotropin hormones. The ongoing system of feedback plays a major role in regulating the synthesis of the steroidal reproductive hormones from the gonads, ie. estrogen and progesterone in females and testosterone in males. Consequently, controlling the pulsatile release of LHRH provides an avenue for the design of novel compounds useful in treating various conditions related to dysfunction of the reproductive cycle and hormone dependent diseases.
Natural mammalian releasing hormone LHRH isolated and purified from porcine and human hypothalamus has been characterized as having the sequence:
(pyro)Glu-His-Trp-Ser-Tyr-Gly-Leu-Arg-Pro-Gly-NH2 as described in AN. Schally, Science, 202:6 (1978). Substitutions and derivatizations of amino acyl residues have been developed to achieve novel compounds useful in treating various disorders related to mammalian reproductive systems. Some derivatives of natural compounds have been shown to exhibit activity as LHRH agonists or as antagonists of LHRH.
Synthetic analogs evidencing activity in modulating LHRH secretion typically comprise peptides of naturally-occurring or non-naturally occurring amino acid residues. Peptide LHRH antagonists characterized by substitution of the nitrogen atom of at least one amide bond are described in U.S. Pat. o. 5,110,904, and U.S. Pat. No. 5,502,035.
Truncated peptide compounds developed as a series of smaller peptide analogs also exhibit biological activity and afford the added advantage of possibly improving oral bioavailability. "Pseudo" peptide compounds, see for example U.S. Pat. No. 5,140,009, are recognized LHRH antagonists. Reduced-size pentapeptides LHRH antagonists are described in pending U.S. Application Ser. No. 132,999. Pending application U.S. Ser. No. 133,055 discloses heptapeptide analogs which provide active compounds truncated from the C-terminus of a decapeptide antagonist sequence.
Non-peptide heterocyclic reproductive hormone regulators have been reported in the literature, see for example, WO 95/29900 and WO 97/21704. Macrolide LHRH antagonists are described in the pending U.S. Application Ser. No. 049,963; see also pending U.S. Application Ser. No. 140,805. European Patent EP 0712845 discloses amine compounds exhibiting LHRH receptor antagonist activity; see also European Patent EP 0187700.
The non-peptide LHRH antagonists of the present invention comprise tetrahydro- isoquinoline derivatives not previously described by the prior art. The compounds are useful in the treating a variety of sex hormone related conditions including precocious puberty, benign prostatic hyperplasia, breast and ovarian tumors, prostate tumors, cryptorchidism, hirsutism in women, gastric motility disorders, dysmenorrhea and endometriosis.

Effects and Utilities of LHRH Antagonists
In practicing the method of the invention, a therapeutically effective amount of a compound of the invention or a pharmaceutical composition containing the same is administered to the human or animal in need of, or desiring, such treatment. The compound may be employed in pure form or, where such forms exist, in pharmaceutically acceptable salt, ester or prodrug form. By a "therapeutically effective amount" of the compound of the invention is meant a sufficient amount of the compound to treat the targeted disorder, at a reasonable benefit risk ratio applicable to any medical treatment, which is administered in such quantities and over such a period of time as is necessary to obtain the desired therapeutic effect. It will be understood, however, that the total daily usage of the compounds and compositions of the present invention will be decided by the attending physician within the scope of sound medical judgment.
The specific therapeutically effective dose level for any particular patient will depend upon a variety of factors including the disorder being treated and the severity of the disorder; activity of the specific compound employed; the specific composition employed; the age, body weight, general health, sex and diet of the patient; the time of administration, route of administration, and rate of excretion of the specific compound employed; the duration of the treatment; drugs used in combination or coincidental with the specific compound employed; and like factors well known in the medical arts. For example, it is well within the skill of the art to start doses of the compound at levels lower than required to achieve the desired therapeutic effect and to gradually increase the dosage until the desired effect is achieved.
The total daily dose of the compound of this invention administered to a human or lower animal may range from about 0.1 to about 100 mg/kg/day or for topical administration from about 0.1 to about 10% in cream, ointment or other topical formulation or for rectal or vaginal administration from about 10 to about 500 mg per dose in a suitable vehicle. For purposes of oral administration, doses may be in the range of from about 1 to about 100 mg/kg/day or, more preferably, of from about 10 to about 20 mg/kg/day. If desired, the effective daily dose may be divided into multiple doses for purposes of administration; consequently, single dose compositions may contain such amounts or submultiples thereof as make up the daily dose.
Compounds and pharmaceutical compositions of the invention may be administered by a variety of routes depending on the specific end use. Exemplary methods of administration include, but are not limited to, orally, rectally, parenterally, intracisternally, intravaginally, intraperitoneally, topically (as by powders, ointments, or drops), bucally, or as an oral or nasal spray. The term "parenteral" as used herein refers to modes of administration which include intravenous, intramuscular, intraperitoneal, intracisternal, subcutaneous and intraarticular injection and infusion.
The pharmaceutical compositions of the present invention comprise a compound of the invention in combination with a pharmaceutically acceptable carrier or excipient. The term "pharmaceutically acceptable carrier" refers to a non-toxic solid, semi-solid or liquid filler, diluent, encapsulating material or formulation auxiliary of any type.
Pharmaceutical compositions of this invention for parenteral injection include pharmaceutically acceptable sterile nonaqueous solutions or aqueous dispersions, suspensions or emulsions as well as sterile powders for reconstitution into sterile injectable solutions or dispersions just prior to use. Examples of suitable aqueous and nonaqueous carriers, diluents, solvents or vehicles include water, ethanol, polyols (such as glycerol, propylene glycol, polyethylene glycol, and the like), carboxymethylcellulose and suitable mixtures thereof, vegetable oils (such as olive oil), and injectable organic esters such as ethyl oleate. Proper fluidity can be maintained, for example, by the use of coating materials such as lecithin, by the maintenance of the required particle size in the case of dispersions, and by the use of surfactants. These compositions may also contain adjuvants such as preservative, wetting agents, emulsifying agents, and dispersing agents. Prevention of the action of microorganisms may be ensured by the inclusion of various antibacterial and antifungal agents, for example, paraben, chlorobutanol, phenol sorbic acid, and the like. It may also be desirable to include isotonic agents such as sugars, sodium chloride, and the like. Prolonged absorption of the injectable pharmaceutical form may be brought about by the inclusion of agents which delay absorption such as aluminum monostearate and gelatin. In some cases, in order to prolong the effect of the drug, it is desirable to slow the absorption of the drug from subcutaneous or intramuscular injection. This may be accomplished by the use of a liquid suspension of crystalline or amorphous material with poor water solubility. The rate of absorption of the drug then depends upon its rate of dissolution which, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally administered drug form is accomplished by dissolving or suspending the drug in an oil vehicle.
Injectable depot forms are made by forming microencapsule matrices of the drug in biodegradable polymers such as polylactide-polyglycolide. Depending upon the ratio of drug to polymer and the nature of the particular polymer employed, the rate of drug release can be controlled. Examples of other biodegradable polymers include poly(orthoesters) and poly(anhydrides) Depot injectable formulations are also prepared by entrapping the drug in liposomes or microemulsions which are compatible with body tissues.
The injectable formulations can be sterilized, for example, by filtration through a bacterial-retaining filter, or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium just prior to use.
Solid dosage forms for oral administration include capsules, tablets, pills, powders, and granules. In such solid dosage forms, the active compound is mixed with at least one inert, pharmaceutically acceptable excipient or carrier such as sodium citrate or dicalcium phosphate and/or a) fillers or extenders such as starches, lactose, sucrose, glucose, mannitol, and silicic acid, b) binders such as, for example, carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidone, sucrose and acacia, c) humectants such as glycerol, d) disintegrating agents such as agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates and sodium carbonate, e) solution retarding agents such as paraffin, f) absorption accelerators such as quaternary ammonium compounds, g) wetting agents such as, for example, cetyl alcohol and glycerol monostearate, h) absorbents such as kaolin and bentonite clay, and i) lubricants such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols and sodium lauryl sulfate, and mixtures thereof. In the case of capsules, tablets and pills, the dosage form may also comprise buffering agents.
Solid compositions of a similar type may also be employed as fillers in soft and hard- filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polyethylene glycols and the like.
The active compounds can also be in micro-encapsulated form with one or more excipients as noted above. The solid dosage forms of tablets, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings, release controlling coatings and other coatings well known in the pharmaceutical formulating art. In such solid dosage forms the active compound may be admixed with at least one inert diluent such as sucrose, lactose or starch.
Such dosage forms may also comprise, as is normal practice, additional substances other than inert diluents, e.g., tableting lubricants and other tableting aids such a magnesium stearate and microcrystalline cellulose. In the case of capsules, tablets and pills, the dosage forms may also comprise buffering agents. They may optionally contain opacifying agents and can also be of a composition that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of embedding compositions which can be used include polymeric substances and waxes.
The active compounds can also be in micro-encapsulated form, if appropriate, with one or more of the above-mentioned excipients.
Liquid dosage forms for oral administration include pharmaceutically acceptable emulsions, solutions, suspensions, syrups and elixirs. In addition to the active compounds, the liquid dosage forms may contain inert diluents commonly used in the art such as, for example, water or other solvents, solubilizing agents and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol,
1 ,3-butylene glycol, dimethyl formamide, oils (in particular, cottonseed, groundnut, corn, olive, castor and sesame oils), glycerol, tetrahydrofuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, and mixtures thereof.
Besides inert diluents, the oral compositions can also include adjuvants such as wetting agents, emulsifying and suspending agents, and sweetening, flavoring and perfuming agents.
Suspensions, in addition to the active compounds, may contain suspending agents as, for example, ethoxylated isostearyl alcohols, polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar-agar, and tragacanth, and mixtures thereof.
Topical administration includes administration to the skin or mucosa, including surfaces of the lung and eye. Compositions for topical administration, including those for inhalation, may be prepared as a dry powder which may be pressurized or non-pressurized. In non-pressurized powder compositions, the active ingredient in finely divided form may be used in admixture with a larger-sized pharmaceutically acceptable inert carrier comprising particles having a size, for example, of up to 100 micrometers in diameter. Suitable inert carriers include sugars such as lactose. Desirably, at least 95% by weight of the particles of the active ingredient have an effective particle size in the range of 0.01 to 10 micrometers.
Dosage forms for topical or transdermal administration of a compound of this invention include ointments, pastes, creams, lotions, gels, powders, solutions, sprays, inhalants or patches. The active component is admixed under sterile conditions with a pharmaceutically acceptable carrier and any needed preservatives or buffers as may be required. Ophthalmic formulation, ear drops, eye ointments, powders and solutions are also contemplated as being within the scope of this invention.
Alternatively, the composition may be pressurized and contain a compressed gas, such as nitrogen or a liquified gas propellant. The liquified propellant medium and indeed the total composition is preferably such that the active ingredient does not dissolve therein to any substantial extent. The pressurized composition may also contain a surface active agent. The surface active agent may be a liquid or solid non-ionic surface active agent or may be a solid anionic surface active agent. It is preferred to use the solid anionic surface active agent in the form of a sodium salt.
Compositions for rectal or vaginal administration are preferably suppositories which can be prepared by mixing the compounds of this invention with suitable non-irritating excipients or carriers such as cocoa butter, polyethylene glycol or a suppository wax which are solid at room temperature but liquid at body temperature and therefore melt in the rectum or vaginal cavity and release the active compound.
The therapeutically effective amount of the compound can also be administered in the form of liposomes. As is known in the art, liposomes are generally derived from phospholipids or other lipid substances. Liposomes are formed by mono- or multilamellar hydrated liquid crystals that are dispersed in an aqueous medium. Any non-toxic, physiologically acceptable and metabolizable lipid capable of forming liposomes can be used. The present compositions in liposome form can contain, in addition to a compound of the present invention, stabilizers, preservatives, excipients, and the like. The preferred lipids are the phospholipids and the phosphatidyl cholines (lecithins), both natural and synthetic. Methods to form liposomes are known in the art. See, for example, Prescott, Ed., Methods in Cell Biology. Volume XIV, Academic Press, New York, N.Y., 1976, p. 33 et seq.
Synthetic Methods
The process of preparing compounds of the invention may be better understood in connection with the following Schemes 1-5. In describing the processes and the Examples which are following, certain abbreviations are used in describing reagents and methods commonly used in the process. Where used herein the abbreviations substitute for the following: DBU for l,8-diazabicyclo[5.4.0]undec-7-ene; DMAP for 4-dimethylaminopyridine; DMF for dimethylformamide; EDCI for l-(3-dimethylaminopropyl)-3-ethylcarbodiirnide; HOBt for 1 -hydroxybenzotriazole hydrate; LAH for lithium aluminum hydride; OMe for methoxy; PCC for pyridinium chlorochromate; and THF for tetrahydrofuran.
As summarized below and further described herein in accordance with the Examples, Schemes 1-5 illustrate processes within the scope of the invention. Scheme 1 describes the general method for preparing tetrahydroisoquinoline derivatives of the general formula (I), which is followed by more preferred syntheses carried out in accordance with Schemes 2-5. The tetrahydroisoquinoline derivatives are prepared from a substituted aminoalkanol, wherein a single carbon of the alkyl chain is disubstituted with an aryl moiety, preferably a phenyl group. Procedures for obtaining the aminoalkanol are readily ascertained by those of skill in the art from methods previously described, for example EP 0712845 for the preparation of 6-amino-4,4- diphenylhexanol. Exemplary synthesis of the diphenyl-substituted aminoalkanol is more particularly illustrated and further detailed in Schemes 2-5 and in the Examples.
As illustrated by Scheme 1, Step (i) represents the N-substitution of the amino moiety by acylating the nitrogen of the amino group or by coupling with an activated carboxylic acid. PCC or Swern oxidation of the alcohol to the aldehyde is shown in Step (ii). Alkylation of an isoquinoline ring as represented by Step (iii) affords the tetrahydroisoquinoline derivative. Alternatively, a reactive leaving group R9 is prepared from the alcohol, Step (ii-a), which is alkylated with the isoquinoline ring or the hydroiodide salt of the isoquinoline moiety represented in Step (iii-a). R9 is selected from the group consisting of halide and mesylate. The variables /, m, n,p, W, X, Y, Z, Ri, and R described in Scheme 1 are as defined in Claim 1. R3 is selected from hydroxy, halo, or an aryl ring substituted with an electron withdrawing group to obtain an activated ester as illustrated by Scheme 1 below.
Scheme 1
The following Schemes 2-5 further describe methods of preparing compounds within the scope of the general formula (I). In particular, Scheme 2 represents a process for preparing a compound of formula (II) starting with the condensation of diphenylacetaldehyde and acrylonitrile and followed by additional chemical transformations well known in the art. Scheme 3 involves a coupling reaction of an aryl-substituted (aryl)alkylamine with a carboxylic acid, followed by cyclization to form a tetraisoquinoline moiety which is an intermediate suitable for alkylating compound 7, 8, or 9 of Scheme 2. A compound of the formula (III) is prepared from
4,4-diphenyl-formylbutyronitrile as illustrated in Scheme 4. Scheme 5 represents a process for preparing a compound of general formula (IV) via a Wittig reaction of 4,4-diphenyl-5-formyl- pentanonitrile followed by conventional chemical steps. The variables Rj, R2, W, X, Y, and Z described in the schemes are the groups defined in Claim 1. The group R3 is selected from hydroxy, halo, or an aryl ring substituted with an electron withdrawing group to obtain an activated ester.
Scheme 2 Condensation of diphenylacetaldehyde and acrylonitrile is carried out in the presence of base to afford a 4,4-diphenyl-formylbutyronitrile The aldehyde is converted to a 6-cyano-4,4,- diphenyl- ,β-unsaturated ester 2 via Wittig reaction. Hydrogenation of 2 in the presence of 10% Pd/C affords compound 3. Treating the ester 3 with lithium aluminum hydride reduces the ester as well as the cyano moiety to form a 4,4-diphenyl-substituted aminoalkanol 4.

Another known method to form isoquinoline ring (A) is by the cyclization of compound 12 with POCl3 to afford compound 15. Reacting compound L5 with sodium cyanoborane yields the isoquinoline derivative (A).
