Description
RECEPTOR ANTAGONISTS Y5 NEUROPEPTIDES
BACKGROUND OF THE INVENTION
The present invention relates to Y5 receptor antagonists of neuropeptides Y which are useful in the treatment of eating disorders and diabetes, pharmaceutical compositions containing the compounds and methods of treatment using the compounds. Neuropeptide Y is a peptide of 36 amino acids that is widely distributed in the central and peripheral nervous systems. This peptide is an intermediary in a variety of physiological effects through its various receptor subtypes. Studies in animals have shown that neuropeptide Y is a powerful stimulus for food ingestion, and it has been shown that activation of Y5 receptors of neuropeptides Y results in hyperphagia and decreased thermogenesis. Therefore, compounds that antagonize neuropeptide Y in the Y5 receptor subtype represent a solution in the treatment of eating disorders such as obesity and hyperphagia. Phenylamides and ureas are known as antiatherosclerotic agents, see for example U.S. Patent No. 4,623,662, and is described in benzoic acid amides as antidiabetic agents in U.S. Patent No. 5,378,728: The N, N-alkylene bis (benzamides) are known as endocrinological agents, see North American patent No.

DETAILED DESCRIPTION OF THE INVENTION
Except where otherwise stated, the following 10 definitions will apply throughout the present description and claims. These definitions apply regardless of whether a term is used by itself or in other terms. Therefore the definition "alkyl" is applied to "alkyl" as well as to the "alkyl" portions of "alkoxy", etc. Alkyl represents branched saturated hydrocarbon chains having the designated carbon atom amount. If the amount of carbon atoms is not specific, for example if the term lower alkyl is used, chain lengths of 1 to 6 carbons are indicated. When X is -CR25) = C (R25) -, both 20 configurations are considered, the cis and the trans configuration. Cycloalkyl represents a saturated carboxylic ring having from 3 to 12 carbon atoms. The C3-C6-cycloalkyl rings are preferred.
In the definition of R16, the term (C3-C? 2) spirocycloalkyl refers to a (C2-Cn) alkylene chain attached at both ends to the same ring carbon, i.e.
similarly, the term (C3-C4) spiroalkylenedioxy refers to the (C2-C3) alkylenedioxy group attached at both ends to the same ring carbon atom, i.e.
in the definition of R6 and R7, the term "heterocyclic ring" refers to 4- to 7- membered saturated rings comprising 1 to 3 heteroatoms independently selected from the group consisting of -O-, -S- and -NH- , the remaining carbon ring members. When a ring
Heterocyclic comprises more than one heteroatom rings are not formed when there are adjacent oxygen atoms, adjacent sulfur atoms, or three consecutive heteroatoms. Examples of heterocyclic rings are tetrahydrofuranyl, pyrrolidinyl, piperidinyl, morpholinyl, thiomorpholinyl and piperazinyl. 20 When two R12 groups form a ring of the formula
those skilled in the art will recognize that the substituents -NR8R9 and -NR8C (O) R9 can not be attached to the carbon adjacent to the pipericinyl nitrogen. Halogen represents fluorine, chlorine, bromine or iodine. 5 Polihalo (C -? - C6) alkyl refers to a straight or branched alkyl chain substituted with 1 to 5 halogen atoms, which may be attached to the same or different carbon atoms, for example -CH2F, -CHF2, CF3, F3CCH2- and -CF2CF3. Hydroxy (CrC6) alkyl refers to an alkyl chain substituted on any substitutable carbon with a hydroxy group. Similarly, oxo (d -C-kajalyl refers to an alkyl chain substituted with a = O portion) Aryl represents phenyl or naphthyl Heteroaryl refers to simple or benzofused aromatic rings of from 5 to 10 members comprising 1 to 3 heteroatoms independently selected of the group consisting of -O-, -S- and N =, with the proviso that the rings do not include adjacent oxygen and / or sulfur atoms.Examples of heteroaryl groups of a ring are pyridyl, isoxazolyl, oxadiazolyl, furanyl, pyrrolyl, thienyl, imidazolyl, pyrazolyl, tetrazolyl, thiazolyl, thiadiazolyl, pyrazinyl, pyrimidinyl, pyridazinyl and triazolyl Examples of benzofused heteroaryl groups are quinolinyl, isoquinolinyl, quinazolinyl, tianaphtenyl (ie benzothienyl), indolyl, benzimidazolyl, benzofuranyl and benzofurazanyl. Also included are the -N-oxides of nitrogen-containing heteroaryl groups All positional isomers
^ ^^ S ^^^^^^^^ Jj ^ ^ ^^^^^^^^^^^ ^^^ g ^^^^^^^ j ^ ^^^^^^^^^^^ ^^^^^^^^^^^^^^^ g are contemplated: for example, 2-pyridyl, 3-pyridyl and 4-pyridyl. Preferred heteroaryl groups are pyridyl, isoxazolyl, thienyl, thiazolyl, pyrazinyl, pyrimidinyl, pyridazinyl, quinolinyl, isoquinolinyl and quinazolinyl. When a variable appears more than once in the structural formula, for example R8, the identity of each variable that appears more than once can be independently selected from the definition for this variable. For the compounds of the invention having at least one asymmetric carbon atom, all isomers, including diastereomers, enantiomers and rotational isomers are contemplated as forming part of the invention. The invention includes d and I isomers in both the pure and mixed forms, including racemic mixtures. The isomers can be prepared using conventional techniques, either by reaction of pure or optically enriched starting materials or by separation of the isomers of a compound of formula I. The compounds of formula I can exist in unsolvated as well as solvated form , including hydrated forms. In general, solvated forms, with pharmaceutically acceptable solvents such as water, ethanol and the like, are equivalent to the forms are solvated for the purposes of this invention. A compound of formula I can form pharmaceutically acceptable salts with inorganic or organic acids. Examples of acids suitable for the formation of salts such as hydrochloric, sulfuric, phosphoric, acetic, citric, malonic, salicylic, malic, fumaric, succinic, ascorbic, maleic, methanesulfonic and other mineral and carboxylic acids which are well known to the experts in the technique. The salts are prepared by contacting the free base forms with a sufficient amount of the desired acid to produce a salt in a conventional manner. The free base forms can be regenerated by treating the salt with a suitable dilute aqueous base solution such as dilute aqueous sodium hydroxide, potassium carbonate, ammonia or sodium bicarbonate. The free base forms differ somewhat in their respective salt forms in regard to certain physical properties, such as solubility in polar solvents, but the salts are otherwise equivalent to their respective free base forms for the purposes of the invention. The compounds of formula I can be produced by methods known to those skilled in the art as shown in the following examples. Typically, the claimed compounds in which X is -S- or -O- can be prepared as shown in the following reaction scheme:
IA
wherein an amine of formula II is reacted with an acid chloride or carbamoyl chloride in the presence of a base, or with a carboxylic acid in the presence of conventional amide coupling agents such as EDC and DMAP. The starting materials of formula II can be prepared using known methods. The compounds of formula I exhibit neuropeptide Y5 antagonist activity, which has been correlated with pharmacological activity to treat eating disorders such as obesity and hyperphagia. The compounds of formula I exhibit pharmacological activity in assay procedures designed to indicate antagonist activity of the Y5 neutropeptide receptor. The compounds are non-toxic in pharmaceutically therapeutic doses.
CAMP assay Cho cells expressing the various NPY receptor subtypes were maintained in Ham's F-12 medium (Gibco-BRL) supplemented with 10% FCS (ICN), 1% penicillin-streptomycin, 1% non-essential amino acids and 200 μg / ml of Geneticin ® (Gibco-BRL # 11811-031) under a 5% humidified CO2 atmosphere. Similarly, HEK-293 cells expressing the various NPY receptor subtypes were maintained in Dulbecco's modified Eagle medium (Gibco-BRL) supplemented with 10% FCS (ICN), 1% penicillin-streptomycin and 200 μg / ml of Geneticin ® (Gibco-BRL
# 11811-031) under humidified CO2 atmosphere at 5%. Two days before the assay, cells from tissue culture flasks T-175 were released using a dissociating solution (1 X: non-enzymatic [Sigma # C 5914] and seeded in 96-well flat bottom tissue culture plates. at a density of 15,000 to 20,000 cells per receptacle.After approximately 48 hours the cell monolayers were rinsed with Hank's balanced salt solution (HBSS) and then preincubated with approximately 150 μl / supplemented test buffer receptacle (HBSS) with 4 Mm of MgCl2, 10 mM of HEPES, 0.2% of BSA [HH] that
contained 1 mM of 3-isobutyl-1-methylxanthine ([IBMX] Sigma # 1-5879) with or without the antagonist compound of interest at 37 ° C. After 20 minutes 1 mM of the assay buffer IBMX-HH (antagonist +) was removed and replaced with a test buffer containing μM (CHO cells) or 5 μM (HEK-293 cells) forskolin (Sigma # F- 6886) and various concentrations of NPY
in the presence or absence of a concentration of the antagonist compound of interest. After 10 minutes the medium was removed and the cell monolayers were treated with 75 μl of ethanol. The tissue culture plates were shaken on a platform shaker for 15 minutes, after which the plates were transferred to a hot water bath in order to
Evaporate the ethanol. After bringing all the wells to dryness, the cell residues were re-solubilized with 250 μl of the Flash Pitate ® test buffer. The amount of cAMP from each receptacle was quantified using the equipment [125] -CAMP Flash Píate ® (NEN # SMP-001) according to the
protocol provided by the manufacturer. The data were expressed as mol cAMP / ml or as control percentage. All data points were determined in triplicate and the EC50 (nM) was calculated using a non-linear (sigmoidal) regression equation (GraphPad Prism ™). The KB of the antagonist compound was estimated using the following formula: KB = [B] / (1- { [A '] / [A].}.) Where [A] is the EC50 of the agonist (NPY) in the absence of antagonist, [A '] is the EC50 of the agonist (NPY) in the presence of an antagonist, and [B] is the concentration of the antagonist.
NPY adhesion receptor assay Human NPY receptors were expressed in CHO cells. Adhesion assays were carried out in 50 mM HEPES, pH, 7.2, 2.5 mM, CaCl2, 1 mM MgCl2 and 0.1% BSA containing 5-10 μg membrane protein and 0.1 nM 125 I-peptide YY (for NPY1, NPY2 and NPY5 receptors) or 0.1 nM of 125l-pancreatic polypeptide (NPY4 receptor) in a total volume of 200 μl. The non-specific adhesion was determined in the presence of 1 uM of NPY. The reaction mixtures were incubated for 90 minutes at 30 ° C (NPY1 receptor) or at room temperature (NPY2, NPY4 and NPY5 receptors), and then filtered through Millipore MAFC glass filter plates that had been pre-soaked in 0.5%. of polyethyleneimine. The filters were washed with phosphate buffered saline, and the radioactivity was measured in a Packard TopCount scintillation counter.
^ ^^^^^^^^^^^^^^^^^^^ g | g ^ ¡g || ^^ g ^^^ gSg > ^^^ g ^^^^^^^ gg ^^ For the compounds of this invention a range of adhesion activity to the neuropeptide receptor Y5 of from about 0.1 to about 1000 nM was observed. The compounds of this invention preferably have an adhesion activity in the range of from about 0.1 to 250 nM, more preferably about 0.1 to 100 nM, and more preferably about 0.1 to 10 nM. To prepare pharmaceutical compositions from the compounds of formula I, inert pharmaceutically acceptable carriers were mixed with the active compounds. The pharmaceutically acceptable carriers can be solid or liquid. Solid form preparations include powders, tablets, dispersible granules, capsules, seals and suppositories. A solid carrier can be one or more substances which can also act as diluents, flavoring agents, solubilizers, lubricants, suspending agents, binders or tablet disintegrating agents; They can also be an encapsulating material. Liquid form preparations include solutions, suspensions and emulsions. As an example, water or water-propylene glycol solutions for parenteral injection may be mentioned. Also included are solid form preparations which are intended to be converted shortly before use into liquid form preparation for oral or parenteral administration. Said liquid forms include solutions, suspensions and emulsions. These particular preparations in
solid form are conveniently provided in unit dosage form and as such are used to provide a single liquid dosage unit. The invention also contemplates alternative administration systems that include but are not necessarily limited to transdermal administration. The transdermal compositions may take the form of creams, lotions and / or emulsions and may be in a transdermal dressing of the matrix or deposit type as conventionally used in the art for this purpose. Preferably the pharmaceutical preparation is in a unit dosage form. In such form the preparation is subdivided into unit doses containing appropriate amounts of the active compound. The unit dosage form can be a packaged preparation, a package containing discrete quantities of preparation such as tablets capsules and powders packed in vials or ampoules. The unit dosage form may also consist of a capsule, seal or the same tablet, or may consist of the appropriate amount of any of these in packaged form. The amount of active compound in a preparation in unit dosage form can be varied or adjusted to from about 0.5 mg to 500 mg, preferably about 0.5 to 100 mg, according to the particular application and potency of the active ingredient and the proposed treatment. The composition may also contain, if desired, other therapeutic agents.
^^^^ tó ^^^^ The daily dose is from about 0.01 to about 20 mg / kg. The dosage may vary depending on the requirements of the patient, the severity of the condition being treated and the particular compound used. The determination of the appropriate dosage for a particular situation is within the experience of experts in the field of medicine. For reasons of convenience, the total daily dosage can be divided and administered in portions throughout the day or by the provision of a continuous supply.
