Definitions

• Adenosine is a naturally occurring nucleoside, which exerts its biological effects by interacting with a family of adenosine receptors known as Ai, A 2a , A 2 t > , and A 3 , all of which modulate important physiological processes.
• Such preferred compounds include compounds of Formula I in which R is hydrogen, R 1 is cycloalkyl of 3-6 carbon atoms, R 2 is alkyl substituted by -SO 3 H, or cycloalkyl substituted by -SO 3 H, or aryl substituted by -SO 3 H; or heteroaryl substituted by - SO 3 H, or heterocyclyl substituted by -SO 3 H, and R 3 is -CH 2 OH, particular where R 4 and R 5 are hydrogen and Y is a covalent bond.
• R 2 is alkyl substituted by -SO 3 H or aryl substituted by -SO 3 H.
• an alkylene group as defined above that is interrupted by 1-5 atoms or groups independently chosen from oxygen, sulfur and NR a -, where R 3 is chosen from hydrogen, optionally substituted alkyl, cycloalkyl, cycloalkenyl, aryl, heteroaryl and heterocycyl, or groups selected from carbonyl, carboxyester, carboxyamide and sulfonyl; or
• substituents may optionally be further substituted by 1-3 substituents chosen from alkyl, carboxy, carboxyalkyl, aminocarbonyl, hydroxy, alkoxy, halogen, CF 3 , amino, substituted amino, cyano, and -S(O) n R, where R is alkyl, aryl, or heteroaryl and n is 0, 1 or 2.
• keto refers to a group -C(O)-.
• thiocarbonyl refers to a group -C(S)-.
• carboxy refers to a group -C(O)-OH.
• the compounds of this invention are capable of forming acid and/or base salts by virtue of the presence of amino and/or carboxyl groups or groups similar thereto.
• pharmaceutically acceptable salt refers to salts that retain the biological effectiveness and properties of the compounds of Formula I, and which are not biologically or otherwise undesirable.
• Pharmaceutically acceptable base addition salts can be prepared from inorganic and organic bases. Salts derived from inorganic bases, include by way of example only, sodium, potassium, lithium, ammonium, calcium and magnesium salts.
• the compound of formula (2) is converted to (2R,3R,4R,5R)-4-acetyloxy-5- (acetyloxymethyl) : 2-(6-chloro-2-iodopurin-9-yl)oxolan-3-yl acetate, the compound of formula (3), by reaction with amyl nitrite in the presence of diiodomethane.
• the reaction is conducted in an inert solvent, for example acetonitrile, at a temperature of about 40-100 0 C, preferably about 8O 0 C, for about 4-24 hours, preferably about 18 hours.
• the product of formula (3) is isolated by conventional means, for example removal of the solvent under reduced pressure and purifying the residue by chromatography.
• excipients include lactose, dextrose, sucrose, sorbitol, mannitol, starches, gum acacia, calcium phosphate, alginates, tragacanth, gelatin, calcium silicate, microcrystalline cellulose, polyvinylpyrrolidone, cellulose, sterile water, syrup, and methyl cellulose.
• the formulations can additionally include: lubricating agents such as talc, magnesium stearate, and mineral oil; wetting agents; emulsifying and suspending agents; preserving agents such as methyl- and propylhydroxy-benzoates; sweetening agents; and flavoring agents.
• the active ingredient, starch and cellulose are passed through a No. 20 mesh U.S. sieve and mixed thoroughly.
• the solution of polyvinylpyrrolidone is mixed with the resultant powders, which are then passed through a 16 mesh U.S. sieve.
• the granules so produced are dried at 50 0 C to 60 0 C and passed through a 16 mesh U.S. sieve.
• the sodium carboxymethyl starch, magnesium stearate, and talc previously passed through a No. 30 mesh U.S. sieve, are then added to the granules which, after mixing, are compressed on a tablet machine to yield tablets each weighing 120 mg.
• Suspensions each containing 50 mg of active ingredient per 5.0 mL dose are made as follows:
• EXAMPLE 14 [0124] An injectable preparation is prepared having the following composition:
• Nonspecific binding is determined by the addition of 10 ⁇ M GTP ⁇ S.
• Agonist stimulated binding is determined as the difference between total binding in the presence of CPA and basal binding determined in the absence of CPA.
• Previous reports have shown that agonist stimulated [ 35 S]GTPyS binding was dependent on the presence of GDP (Gierschik et al., 1991; Lorenzen et al., 1993; Traynor & Nahorski, 1995). In preliminary experiments, it was found that 10 ⁇ M GDP gave the optimal stimulation of CPA dependent [ 35 S]GTPyS binding and this concentration was therefore used in all studies.
• 0.5 nM [ 35 SJGTPyS is incubated with 0.5-1000 nM GTPyS. At the end of the incubation, each suspension is filtered and the retained radioactivity determined as described above.
• the amount of bound [ 125 I] cAMP to the fluoromicrospheres is determined by counting in a microtitre plate scintillation counter for 2 minutes. Comparison of counts with standard curves generated for cAMP using a similar protocol affords the cAMP present after cell lysis.
