[Background technology]

[0003] Adenosine, an endogenous nucleoside, is ubiquitous inside and outside living cells. It plays several physiological roles in maintaining homeostasis in cells, tissues, and organs. Adenosine is classified as A1, A 2A , A 2B It can exert its biological effects by interacting with the family of adenosine receptors, known as the A3 adenosine receptor. The A1 adenosine receptor mediates tissue protection, particularly cardioprotection mechanisms. 2A Adenosine receptors regulate coronary vasodilation and cancer immunity. 2B Adenosine receptors play a role in signaling pathways.

[0004] Some A 2B Adenosine receptor antagonists are relatively insoluble in aqueous media and / or difficult to formulate using conventional pharmaceutical excipients, and therefore may be difficult to formulate to provide reproducible plasma levels of the compound in mammals, particularly humans. 2B There is a need to improve the bioavailability of adenosine receptor antagonists.

[0091] In some cases, a prodrug can be hydrolyzed by an esterase (e.g., in the gastrointestinal tract and / or in the blood) to convert it to compound 1 in aqueous solution. In some cases, an acid-unstable prodrug can be converted to compound 1 in an acidic environment (e.g., in the stomach). In some cases, a prodrug that is stable in an acidic environment and / or stable against hydrolysis by an esterase may not be a good candidate for compound 1.

Sci. 1977, 66, 1-19.P. H. Stahl and CG Wermuth, editors, Handbook of Pharmaceutical Salts: Properties, Selection and Use, Weinheim / Zurich:Wiley-VCH / VHCA, 2002. Pharmaceutical salts are typically more readily and rapidly soluble in gastric and intestinal fluids than nonionic species, and are therefore useful in solid dosage forms. Furthermore, their solubility often correlates with pH, ​​allowing for selective dissolution in any part of the gastrointestinal tract, and this ability can be manipulated as a form of delayed-release and sustained-release behavior. In addition, since salt-forming molecules can be in equilibrium with neutral forms, their passage through biological membranes can be regulated.

[0116] The term "salt" includes, but is not limited to, salts that retain one or more of the activity and properties of free acids and bases, and are not undesirable. Exemplary examples of salts include, but are not limited to, sulfates, pyrosulfates, bisulfates, sulfites, bisulfites, phosphates, monohydrogen phosphate, dihydrogen phosphate, metaphosphate, pyrophosphates, chlorides, bromides, iodides, acetates, propionates, decanoic acid, caprylates, acrylates, formates, isobutyrates, caproates, heptanoic acid, propiolates, oxalates, malonates, succinates, suberates, sebacates, fumarates, maleates, butyn-1,4-geoate, hexyn-1,6-geoate, benzoates, chlorobenzoates, methyl benzoate, dinitrobenzoate, hydroxybenzoic acid, methoxybenzoic acid, and phthalates.

A hydrate is formed when the solvent is water, or an alcoholate is formed when the solvent is alcohol. Solvates of the compounds described herein are conveniently prepared or formed during the processes described herein. In addition, the compounds provided herein exist optionally in non-solvated forms as well as solvated forms.

[0118] Unless otherwise indicated, whenever a structure disclosed or illustrated herein has a stereocenter, the stereocenter may be R or S in each case.

[0119] Individual stereoisomers are obtained, if necessary, by methods such as stereoselective synthesis and / or separation of stereoisomers by chiral chromatography column. In some embodiments, the compounds described herein are prepared as their individual stereoisomers by reacting a racemic mixture of the compounds with an optically active resolving agent to form a pair of diastereomer isomer compounds / salts, separating the diastereomers, and recovering the optically pure enantiomers. In some embodiments, the decomposition of the enantiomers is carried out using covalent diastereomer derivatives of the compounds described herein. In other embodiments, the diastereomers are separated by separation / decomposition techniques based on differences in solubility. In other embodiments, the separation of stereoisomers is carried out by chromatography, or by forming diastereomer salts and separating them by recrystallization or chromatography, or by any combination thereof.

[0445] Pharmaceutical composition In some embodiments, the compounds described herein are formulated into pharmaceutical compositions. The pharmaceutical compositions are formulated conventionally using one or more pharmaceutically acceptable inert components that facilitate the treatment of the active compound into a preparation for pharmaceutical use. The appropriate formulation depends on the chosen route of administration. A summary of the pharmaceutical compositions described herein can be found, for example, in: Remington: The Science and Practice of Pharmacy, Nineteenth Ed (Easton, Pa.: Mack Publishing Company, 1995); Hoover, John E., Remington's Pharmaceutical Sciences, Mack Publishing Co., Easton, Pennsylvania 1975; Liberman, HAand Lachman, L., Eds., Pharmaceutical Dosage Forms, Marcel Decker, Seen in New York, NY, 1980; and Pharmaceutical Dosage Forms and Drug Delivery Systems, Seventh Ed. (Lippincott Williams & Wilkins 1999), which are incorporated herein by reference for such disclosures.

[0446] In some embodiments, the compounds described herein are administered alone or in combination with pharmaceutically acceptable carriers, excipients, or diluents in pharmaceutical compositions. Administration of the compounds and compositions described herein can be achieved by methods that enable delivery of the compounds to the site of action.

[0447] Pharmaceutical compositions incorporating the compounds described herein may take any pharmaceutically acceptable physical form. Pharmaceutical compositions for oral administration are particularly preferred. Examples of such pharmaceutical compositions include, but are not limited to, tablets, lozenges, aqueous or oily suspensions, dispersible powders or granules, emulsions, hard or soft capsules, or syrups or elixirs.

[0448] Pharmaceutical compositions can be prepared according to known methods of formulation used in pharmacy. All common types of compositions are considered, but are not limited to, tablets, chewable tablets, capsules, and solutions.

[0449] Capsules can be prepared by mixing the compounds described herein with a suitable diluent and filling the capsule with an appropriate amount of the mixture. Tablets can be prepared by direct compression, wet granulation, or dry granulation. These formulations typically incorporate diluents, binders, lubricants, and disintegrants, as well as the compounds described herein as active therapeutic agents. Lubricants in tablet formulations may help prevent the tablet and punches from sticking to the die. Tablet disintegrants are substances that expand when wet, causing the tablet to disintegrate and release the compound. Enteric-coated formulations are often used to protect the active ingredient from the highly acidic components of the stomach and to slow its disintegration and absorption in the gastrointestinal tract. Such formulations are made by coating a solid dosage form with a polymer film that is insoluble in acidic environments and soluble in basic environments. Tablets are often coated with flavorings and sugars as fillers. [Examples]

Exemplary compounds were administered orally via enteral feeding to groups of three rats using a single oral dose of 5 mg / kg. Each oral dose was prepared as a 0.5% methylcellulose turbidi in water. Blood samples were collected sequentially from each rat at 0, 15, and 30 minutes post-administration, and then at 1, 2, 4, 8, and 24 hours.

[0599] The concentrations of administered compounds and their corresponding metabolites (compound 1) in rat plasma were determined by HPLC-tandem mass spectrometry (LC / MS / MS). 50 μL of plasma PPT with ISTD in MeOH / acetonitrile (1:1, v / v). 200 μL of 5 ng / mL terfenadine and buspirone were added to MeOH / acetonitrile (1:1, v / v) and mixed well. 5 μL of MeOH was added to all samples, vortexed for 1 minute, and centrifuged at 4000 rpm for 15 minutes. The supernatant was diluted 3-fold with water (containing 0.1% FA) and injected for LC / MS / MS analysis.
