Field of the Invention
This invention relates to new tricyclic non-peptide vasopressin antagonists which are useful in treating conditions where decreased vasopressin levels are desired, such as in congestive heart failure, in disease conditions with excess renal water reabsorption and in conditions with increased vascular resistance and coronary vasoconstriction.
2.
Background of the Invention
Vasopressin is released from the posterior pituitary either in response to increased plasma osmolarity detected by brain osmoreceptors or decreased blood volume and blood pressure sensed by low-pressure volume receptors and arterial baroreceptors. The hormone exerts its action through two well defined receptor subtypes: vascular V<sub>1</sub> and renal epithelial V<sub>2</sub> receptors. Vasopressin-induced antidiuresis, mediated by renal epithelial V<sub>2</sub> receptors, helps to maintain normal plasma osmolarity, blood volume and blood pressure.
Vasopressin is involved in some cases of congestive heart failure where peripheral resistance is increased. V<sub>1</sub> antagonists may decrease systemic vascular resistance, increase cardiac output and prevent vasopressin induced coronary vasoconstriction. Thus, in conditions with vasopressin induce increases in total peripheral resistance and altered local blood flow, V<sub>1-</sub>antagonists may be therapeutic agents. V<sub>1</sub> antagonists may decrease blood pressure, induced hypotensive effects and thus be therapeutically useful in treatment of some types of hypertension.
The blockage of V<sub>2</sub> receptors is useful in treating diseases characterized by excess renal reabsorption of free water. Antidiuresis is regulated by the hypothalamic release of vasopressin (antidiuretic hormone) which binds to specific receptors on renal collecting tubule cells. This binding stimulates adenylyl cyclase and promotes the cAMP-mediated incorporation of water pores into the luminal surface of these cells. V<sub>2</sub> antagonists may correct the fluid retention in congestive heart failure, liver cirrhosis, nephritic syndrome, central nervous system injuries, lung disease and hyponatremia.
Elevated vasopressin levels occur in congestive heart failure which is more common in older patients with chronic heart failure. In patients with hyponatremic congestive heart failure and elevated vasopressin levels, a V<sub>2</sub> antagonist may be beneficial in promoting free water excretion by antagonizing the action of antidiuretic hormone, On the basis of biochemical and pharmacological effects of the hormone, antagonists of vasopressin are expected to be therapeutically useful in the treatment and/or prevention of hypertension, cardiac insufficiency, coronary vasospasm, cardiac ischemia, renal vasospasm, liver cirrhosis, congestive heart failure, nephritic syndrome, brain edema, cerebral ischemia, cerebral hemorrhage-stroke, thrombosis-bleeding and abnormal states of water retention.

The pyridine carboxylic acids are activated for coupling by conversion to an acid chloride, bromide or anhydride or by first reacting with an activating reagent such as <u style="single">N</u>,<u style="single">N</u>-dicyclocarbodiimide, diethyl cyanophosphonate and related "peptide type" activating reagents. The method of activating the acids <u style="single">20</u> for coupling to the tricyclic derivatives <u style="single">3a</u> and <u style="single">3b</u> is chosen on the basis of compatibility with other substituent groups in the molecule. The method of choice is the conversion of the 3-pyridinyl carboxylic acids <u style="single">20</u> to the corresponding 3-pyridinylcarbonyl chlorides. The 3-pyridinylcarbonyl chlorides <u style="single">22</u> may be prepared by standard procedures known in the art, such as reaction with thionyl chloride, oxalyl chloride and the like. The coupling reaction is carried out in solvents such as halogenated hydrocarbons, toluene, xylene, tetrahydrofuran, or dioxane in the presence of pyridine or tertiary bases such as triethylamine and the like (Scheme 7).

In general, when the 3-pyridinyl carboxylic acids <u style="single">20</u> are activated with "peptide type" activating reagents, higher temperatures are required than when the 3-pyridinylcarbonyl chlorides are used. <chemistry id="chem0107" num="0107"><img file="EP0804438B1_D0107.tif" /></chemistry><chemistry id="chem0108" num="0108"><img file="EP0804438B1_D0108.tif" /></chemistry> The starting materials <u style="single">3a</u> and <u style="single">3b</u> in the foregoing Schemes 1-7 may be prepared as follows. In accordance with Scheme 8, alkylation of heterocycles of structural type <u style="single">24</u> with an alkylating moiety such as <u style="single">23</u> gives intermediates <u style="single">25</u>. The heterocycle <u style="single">24</u> may contain an α-carboxaldehyde function or an α-carboxylic and/or ester function as shown in Scheme 8. Where the intermediate <u style="single">25</u> (R<sup>15</sup>=H) contains an α-carboxaldehyde group, hydrogenation with palladium-on-carbon gives reduction and ring closure in one step to give <u style="single">29</u>.
In derivatives <u style="single">25</u> where R<sup>15</sup> is an α-carboxylic and/or an α-carboxylic ester function, the intermediate amino acid derivative <u style="single">27</u> is first isolated and then ring closed. The ring closure of derivatives <u style="single">27</u> may be carried out by heating or by activation of the acid function (<u style="single">27</u>:R<sup>15</sup>=H) for ring closure. The cyclic lactams <u style="single">28</u> are conveniently reduced with diborane or lithium aluminum hydride to give intermediates <u style="single">29</u>. Reaction of tricyclic derivatives <u style="single">29</u> with aroyl chlorides (ArCOCl), where Ar is as hereinbefore defined, gives diazepines <u style="single">26</u>.
Tricyclic derivatives of structural type <u style="single">36</u> may be prepared as shown in Scheme 9. Formylation of <u style="single">32</u> under known conditions in the literature, such as Vilsmeier formylation, gives intermediates <u style="single">35</u> which on reduction and ring closure affords tricyclics <u style="single">37</u>.
Where the ring containing the symbol Z is a substituted or unsubstituted phenyl group, the procedure gives 4,5-dihydropyrrolo[1,2-a]-quinoxalines <u style="single">36</u>. These derivatives <u style="single">36</u> and <u style="single">37</u> may be reacted with aroyl chlorides (ArCOCl) wherein Ar is as previously defined or with a substituted or unsubstituted 6-nitropyridine-3-carbonyl chloride or with a nitrogen protecting group, such as benzyloxycarbonyl chloride to give compounds <u style="single">38</u> and <u style="single">39</u>.

Halogenation, formylation and acetylation of derivatives <u style="single">36</u> gives 1-substituted 4,5-dihydropyrrolo[1,2-a]quinoxalines. The derivatives <u style="single">38</u>, <u style="single">39</u>, <u style="single">40</u> and <u style="single">41</u> wherein R<sup>16</sup> is a substituted or unsubstituted 6-nitro-3-pyridinylcarbonyl group are reduced to give the 6-amino-3-pyridinylcarbonyl derivatives <u style="single">42d</u> and <u style="single">43d</u> which are reacted with reagents Ar'COCl, Ar'CH<sub>2</sub>COCl or <chemistry id="chem0109" num="0109"><img file="EP0804438B1_D0109.tif" /></chemistry> wherein Ar' and R<sub>b</sub> are as previously hereinbefore defined, to give tricyclic diazepines <u style="single">44</u> and <u style="single">45</u>. <chemistry id="chem0110" num="0110"><img file="EP0804438B1_D0110.tif" /></chemistry><chemistry id="chem0111" num="0111"><img file="EP0804438B1_D0111.tif" /></chemistry><chemistry id="chem0112" num="0112"><img file="EP0804438B1_D0112.tif" /></chemistry>

The compounds of the present invention can be used in the form of salts derived from pharmaceutically or physiologically acceptable acids or bases. These salts include, but are not limited to, the following: salts with inorganic acids such as hydrochloric acid, sulfuric acid, nitric acid, phosphoric acid and, as the case may be, such organic acids as acetic acid, oxalic acid, succinic acid, and maleic acid. Other salts include salts with alkali metals or alkaline earth metals, such as sodium, potassium, calcium or magnesium or with organic bases. The compounds can also be used in the form of esters, carbamates and other conventional "pro-drug" forms, which, when administered in such form, convert to the active moiety <i><u style="single">in</u><u style="single">vivo.</u></i>
When the compounds are employed for the above utilities, they may be combined with one or more pharmaceutically acceptable carriers, for example, solvents, diluents and the like, and may be administered orally in such forms as tablets, capsules, dispersible powders, granules, or suspensions containing, for example, from about 0.05 to 5% of suspending agent, syrups containing, for example, from about 10 to 50% of sugar, and elixirs containing, for example, from about 20 to 50% ethanol, and the like, or parenterally in the form of sterile injectable solutions or suspensions containing from about 0.05 to 5% suspending agent in an isotonic medium. Such pharmaceutical preparations may contain, for example, from about 25 to about 90% of the active ingredient in combination with the carrier, more usually between about 5% and 60% by weight.
The effective dosage of active ingredient employed may vary depending on the particular compound employed, the mode of administration and the severity of the condition being treated. However, in general, satisfactory results are obtained when the compounds of the invention are administered at a daily dosage of from about 0.5 to about 500 mg/kg of animal body weight, preferably given in divided doses two to four times a day, or in a sustained release form. For most large mammals the total daily dosage is from about 1 to 100 mg, preferably from about 2 to 80 mg. Dosage forms suitable for internal use comprise from about 0.5 to 500 mg of the active compound in intimate admixture with a solid or liquid pharmaceutically acceptable carrier. This dosage regimen may be adjusted to provide the optimal therapeutic response. For example, several divided doses may be administered daily or the dose may be proportionally reduced as indicated by the exigencies of the therapeutic situation.
These active compounds may be administered orally as well as by intravenous, intramuscular, or subcutaneous routes. Solid carriers include starch, lactose, dicalcium phosphate, microcrystalline cellulose, sucrose and kaolin, while liquid carriers include sterile water, polyethylene glycols, non-ionic surfactants and edible oils such as corn, peanut and sesame oils, as are appropriate to the nature of the active ingredient and the particular form of administration desired. Adjuvants customarily employed in the preparation of pharmaceutical compositions may be advantageously included, such as flavoring agents, coloring agents, preserving agents, and antioxidants, for example, vitamin E, ascorbic acid, BHT and BHA.
The preferred pharmaceutical compositions from the standpoint of ease of preparation and administration are solid compositions, particularly tablets and hard-filled or liquid-filled capsules. Oral administration of the compounds is preferred.
These active compounds may also be administered parenterally or intraperitoneally. Solutions or suspensions of these active compounds as a free base or pharmacologically acceptable salt can be prepared in water suitably mixed with a surfactant such as hydroxypropylcellulose. Dispersions can also be prepared in glycerol, liquid, polyethylene glycols and mixtures thereof in oils. Under ordinary conditions of storage and use, these preparations contain a preservative to prevent the growth of microorganisms.
The pharmaceutical forms suitable for injectable use include sterile aqueous solutions or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersions. In all cases, the form must be sterile and must be fluid to the extent that easy syringability exits. It must be stable under conditions of manufacture and storage and must be preserved against the contaminating action of microorganisms such as bacterial and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol (e.g., glycerol, propylene glycol and liquid polyethylene glycol), suitable mixtures thereof, and vegetable oil.
The new tricyclic non-peptide vasopressin antagonists of this invention are useful in treating conditions where decreased vasopressin levels are desired, such as in congestive heart failure, in disease conditions with excess renal water reabsorption and in conditions with increased vascular resistance and coronary vasoconstriction.
In particular, the vasopressin antagonists of this invention are therapeutically useful in the treatment and/or prevention of hypertension, cardiac insufficiency, coronary vasospasm, cardiac ischemia, renal vasospasm, liver cirrhosis, congestive heart failure, nephritic syndrome, brain edema, cerebral ischemia, cerebral hemorrhage-stroke, thrombosis-bleeding and abnormal states of water retention.
In particular, the oxytocin antagonists of this invention are useful in the prevention of preterm labor and premature birth which is a significant cause of infant health problems and infant mortality.
