FUSED COMPOUNDS THAT INHIBIT VANILLOID RECEPTOR SUBTYPE 1 (VR1) RECEPTOR
This application claims priority to U.S. Provisional Application Serial No. 60/477894 filed on June 12,2003.
FIELD OF THE INVENTION
The present invention relates to compounds of formula (J), which are useful for treating disorders caused by or exacerbated by vanilloid receptor activity and pharmaceutical compositions containing compounds of formula (I). The compounds of the present invention are useful in treating pain, bladder overactivity, or urinary incontinence.
BACKGROUND OF INVENTION
Nociceptors are primary sensory afferent (C and A8 fibers) neurons that are activated by a wide variety of noxious stimuli including chemical, mechanical, thermal, and proton (pH < 6) modalities. The lipophilic vanilloid, capsaicin, activates primary sensory fibers via a specific cell surface capsaicin receptor, cloned as VR1. The intradermal administration of capsaicin is characterized by an initial burning or hot sensation followed by a prolonged period of analgesia. The analgesic component of VR1 receptor activation is thought to be mediated by a capsaicin-induced desensitization of the primary sensory afferent terminal. Thus, the long lasting antinociceptive effect of capsaicin has prompted the clinical use of capsaicin analogs as analgesic agents. Further, capsazepine, a capsaicin receptor antagonist can reduce inflammation-induced hyperalgesia in animal models. VR1 receptors are also localized on sensory afferents, which innervate the bladder. Capsaicin or resiniferatoxin has been shown to ameliorate incontinence symptoms upon injection into the bladder.
The VR1 receptor has been called a "polymodal detector" of noxious stimuli since it can be activated in several ways. The receptor channel is activated by capsaicin and other vanilloids and thus is classified as a ligand-gated ion channel. VR1 receptor activation by capsaicin can be blocked by the competitive VR1 receptor antagonist, capsazepine. The channel can also be activated by protons. Under mildly acidic conditions (pH 6-7), the affinity of capsaicin for the receptor is increased, whereas at pH <6, direct activation of the channel occurs. In addition, when membrane temperature reaches 43°C, the channel is opened. Thus heat can directly gate the channel in the absence of ligand. The capsaicin
WO 2004/111009 PCT/US2004/018590
analog, capsazepine, which is a competitive antagonist of capsaicin, blocks activation of the channel in response to capsaicin, acid, or heat
The channel is a nonspecific cation conductor. Both extracellular sodium and calcium enter through the channel pore, resulting in cell membrane depolarization. This depolarization increases neuronal excitability, leading to action potential firing and transmission of a noxious nerve impulse to the spinal cord. In addition, depolarization of the peripheral terminal can lead to release of inflammatory peptides such as, but not limited to, substance P and CORP, leading to enhanced peripheral sensitization of tissue.
Recently, two groups have reported the generation of a "knock-out" mouse lacking the VR1 receptor (VR1(-/-)). Electrophysiological studies of sensory neurons (dorsal root ganglia) from these animals revealed a marked absence of responses evoked by noxious stimuli including capsaicin, heat, and reduced pH. These animals did not display any overt signs of behavioral impairment and showed no differences in responses to acute non-noxious thermal and mechanical stimulation relative to wild-type mice. The VR1 (-/-) mice also did not show reduced sensitivity to nerve injury-induced mechanical or thermal nociception. However, the VR1 knock-out mice were insensitive to the noxious effects of intradermal capsaicin, exposure to intense heat (50-55°C), and failed to develop thermal hyperalgesia following the intradermal administration of carrageenan.
The compounds of the present invention are novel VR1 antagonists and have utility in treating pain, bladder overactivity, or urinary incontinence.
SUMMARY OF THE INVENTION

The present invention also provides pharmaceutical compositions that comprise compounds of the present invention. The pharmaceutical compositions comprise compounds of the present invention that may be formulated together with one or more non-toxic pharmaceutically acceptable carriers.
The pharmaceutical compositions of this invention can be administered to humans and other mammals orally, rectally, parenterally, intracisternally, intravaginally, intraperitoneally, topically (as by powders, ointments or drops), bucally or as an oral or nasal spray.
Some examples of materials which can serve as pharmaceutically acceptable carriers are sugars such as, but not limited to, lactose, glucose and sucrose; starches such as, but not limited to, corn starch and potato starch; cellulose and its derivatives such as, but not limited to, sodium carboxymethyl cellulose, ethyl cellulose and cellulose acetate; powdered tragacanth; malt; gelatin; talc; excipients such as, but not limited to, cocoa butter and suppository waxes; oils such as, but not limited to, peanut oil, cottonseed oil, safflower oil,
WO 2004/111009 PCT/US2004/018590
sesame oil, olive oil, com oil and soybean oil; glycols; such a propylene glycol; esters such as, but not limited to, ethyl oleate and ethyl laurate; agar, buffering agents such as, but not limited to, magnesium hydroxide and aluminum hydroxide; alginic acid; pyrogen-free water; isotonic saline; Ringer's solution; ethyl alcohol, and phosphate butler solutions, as well as other non-toxic compatible lubricants such as, but not limited to, sodium lauryl sulfate and magnesium stearate, as well as coloring agents, releasing agents, coating agents, sweetening, flavoring and perfuming agents, preservatives and antioxidants can also be present in the composition, according to the judgment of the formulator.
Pharmaceutical compositions of this invention for parenteral injection comprise pharmaceutically acceptable sterile aqueous or nonaqueous solutions, 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), vegetable oils (such as olive oil), injectable organic esters (such as ethyl oleate) and suitable mixtures thereof. 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 preservatives, wetting agents, emulsifying agents and dispersing agents. Prevention of the action of microorganisms can 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 can be brought about by the inclusion of agents that 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 can 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.

Alternatively, the tosylate salt of the amine may be isolated as follows: The product solution from debenzylation (38.33 g 5-/-Butyl-aminoindan) was distilled under reduced pressure to -390 mL. Toluene (460 mL) was added, then the mixture was distilled again under reduced pressure ~390 mL. The chase distillation with toluene was repeated three more times (460 mL each) to effectively reduce the levels of methanol and acetic acid. Product precipitated during these chase distillations. The product was obtained by filtration. The wetcake was washed with toluene and dried in a vacuum oven. Yield = 96.4% (w/w), 99.2% pure, 99.6% ee.
Resolution of 5-tert-butyl-indan-ylamine via N-Ac-D-leucine salt formation
To a 5 L jacketed round bottom flask was charged JV-Ac-D-leucine (232.0 g, 1.1 equiv), amine (230.5 g by assay), and MeOH (3 L). After heating the mixture to reflux, more MeOH was added in portions to dissolve all the solids. A total of 4025 mL MeOH (17.5 vol) was needed to obtain a clear solution.
The solution was cooled to ambient over 13 hours via the jacket temperature control. After stirring at room temp for at least 4 hrs, the slurry was filtered. The wetcake was washed with toluene (460 mL), then dried in a 40 °C vacuum oven for ~20 hours.
The white solid obtained was 243.9 g, 55.3% yield, 100 % potent (127.4 g amine). By Mosher's amides, the material was 98.8% ee (170 to 1 favoring the R-amine). The
WO 2004/111009 PCT/US2004/018590
filtrates were combined, concentrated and set aside. This material was 76.5% potent (contained 92.0 g amine), 61.5% ee (4.2 to 1 favoring the R-amine).
The white solid was dissolved in 0.5 M NaOH (1.5 L), and the amine extracted with CH2CI2 (2 L, 2 x 250 mL). The organic layers were combined, dried over Na2S04, and concentrated.
The crude amine weighed 132.56 g, 93.7% pure. This yellow oil was subjected to coupling without further purification.
A'-Acetyl-D-leucine can be recovered from the aqueous layer from above (free-basing with 0.5 M NaOH). To the solution was added cone HC1 until the pH reached ~1. The white solids were filtered and dried overnight in a 40 °C vacuum oven. Approximately 75 mL of cone HC1 was needed to accomplish the pH adjustment The recovered white solid was 107.97 g (93.0% w/w recovery), 95.7% PA (0.7%PA of amine). The remaining aqueous solution still contained some #-Ac-D-leucine.
Second alternative preparation of (1R)-5-tert-butyl-23-dihydro-1H-inden-l-ylamine
To a 2 L 3-neck round bottom flask was charged 5-tert-butyl-indan-l-one (120.84 g), toluene (906 mL, 7.5 vol), and (R)-memylben2ylamine (165.5 mL, 2.0 equiv). The solution was heated to 110 ± 10 °C under a slight nitrogen sweep to achieve a slow atmospheric distillation for ~22 hours. The total volume was further reduced by vacuum distillation to -420 mL.
To a 1 L reactor was charged 5% Pd/C (14.0 g), imine solution (148 g of solution made above), and methanol (350 mL). The mixture was adjusted to ~0 °C, then hydrogenated under 40 psi H2 pressure overnight To the reaction mixture was then charged glacial acetic acid (34.4 mL, 2.5 equiv). The debenzylation reaction occurred under 40 psi of H2 pressure at ~40 °C. When the reaction was complete, the catalyst was filtered and washed with methanol.
A solution of the product and TsOH-H2O (43.31 g, 1.0 equiv relative to product by solution assay) in a 1L 3-necked round bottom flask was concentrated under reduced pressure to ~245 mL. The thick oil was heated to >60 °C, then water (410 mL) was added slowly while maintaining the internal temperature at NLT 60 °C. After mixing at ~65 °C for ~30 min, the mixture was cooled to room temperature. The crude crystals were collected by filtration, and the wetcake was washed with water (2 x 205 mL). The wetcake was returned
WO 2004/111009 PCT/US2004/018590
to the flask along with toluene (300 mL) and methanol (3.0 mL). The mixture was heated to -65 °C for ~30 min, then cooled back to room temperature. The desired product was isolated by filtration, and the wetcake was washed with toluene (2 x 100 mL). The material was dried in a 65 °C vacuum oven. Yield = 77.9% (w/w), 100% ee.

Alternative method of preparing N-[(1R)-5-tert-butyl-2,3-dihydro-1H-inden-l-yl]-N'-1H-
Indazol-4-ylurea.
Step A
4-2,5-dioxo-pyrrolidin-l-yloxycarbonylamino)-indazole-l-carboxylic acid methyl ester

charged the aminoindazole carbamate (94.5 g, 1.0 equiv.), N,N'-disuccinimidy carbonate
(113.8 g, 1.07 eq), and dry acetonitrile (950 mL, KF - 0.06%). Pyridine (32.8 g, 1.0 eq) was
added to the mixture and it was heated to 40 °C and stirred for 15 h during which time a solid
precipitated. The solid was filtered, washed with fresh dry acetonitrile (3X100 mL), and
dried in a vacuum oven at 40 °C to afford 130.1 g (92.9 % potency adjusted) of the activated
succinimidyl carbamate as a light brown solid.

was precooled to 20°C on a water bath. After stirring for 0.5 hour, the reaction was found
complete by HPLC, and the mixture was poured into water (825 mL). An exotherm to 30 °C
was observed. After cooling to ambient temperature, the precipitate was filtered off and
washed with (1:1) methanol/water (200 mL). The washes were slow, as the wet cake tended
to absorb the solvent The wet cake was dried under vacuum overnight at 65 °C to give 34.1 g
of the material, which was assayed for 30.7 g of the product by HPLC method. The crude
was dissolved in 600 mL of methanol at reflux. The solution was filtered hot and distilled to

WO 2004/111009 PCT/US2004/018590
Life Technologies (Grand Island, NY). G418 sulfate was obtained from Calbiochem-Novabiochem Corp. (San Diego, CA). Capsaicin (8-methyl-N-vanillyl-6-nonenainide) was obtained from Sigma-Aldrich, Co. (St. Louis, MO). Fluo-4 AM (N-[4-[6-[(acetyloxy)memoxy]-2,7-dffluoi^3-oxo-3H-xM [(acetyloxy)meraoxy]-2-oxyemyl]amino]-5-memy^
[(acetyloxy)methoxy]-2-oxyethyl]-glycine, (acetyloxy)methyl ester) was purchased from Molecular Probes (Eugene, OR).
The cDNAs for the human VR1 receptor were isolated by reverse transcriptase-polymerase chain reaction (RT-PCR) from human small intestine poly A+RNA supplied by Clontech (Palo Alto, CA) using primers designed surrounding the initiation and termination codons identical to the published sequences (Hayes et ah Pain Vol. 88 pages 205-215, 2000). The resulting cDNA PCR products were subcloned into pCIneo mammalian expression vector (Promega) and fully sequenced using fluorescent dye-terminator reagents (Prism, Perkin-Elmer Applied Biosystems Division) and a Perkin-Elmer Applied Biosystems Model 373 DNA sequencer or Model 310 genetic analyzer. Expression plasmids encoding the hVRl cDNA were transfected individually into 1321N1 human astrocytoma cells using Lipofectamine™. Forty-eight hours after transfection, the neomycin-resistant cells were selected with growth medium containing 800 u.g/mL Geneticin (Gibco BRL). Surviving individual colonies were isolated and screened for VR1 receptor activity. Cells expressing recombinant homomeric VR1 receptors were maintained at 37 °C in D-MEM containing 4 mM L-glutamine, 300 ng/mL G418 (Cal-biochem) and 10% fetal bovine serum under a humidified 5% C02 atmosphere.
The functional activity of compounds at the VR1 receptor was determined with a Ca2+ influx assay and measurement of intracellular Ca2+ levels ([Ca2+]i). All compounds were tested over an 11-point half-log concentration range. Compound solutions were prepared in D-PBS (4x final concentration), and diluted serially across 96-well v-bottom tissue culture plates using a Biomek 2000 robotic automation workstation (Beckman-Coulter, Inc., Fullerton, CA). A 0.2 uM solution of the VR1 agonist capsaicin was also prepared in D-PBS. The fluorescent Ca2+ chelating dye fluo-4 was used as an indicator of the relative levels of [Ca2+]i in a 96-well format using a Fluorescence Imaging Plate Reader (FLIPR)(Molecular Devices, Sunnyvale, CA). Cells were grown to confluency in 96-well black-walled tissue culture plates. Then, prior to the assay, the cells were loaded with 100 uL per well of fluo-4
135
WO 2004/111009 PCT/US2004/018590
AM (2 uM, in D-PBS) for 1-2 hours at 23 °C. Washing of the cells was performed to remove extracellular fluo-4 AM (2 x 1 mL D-PBS per well), and afterward, the cells were placed in the reading chamber of the FLIPR instrument 50 ]xL of the compound solutions were added to the cells at the 10 second time mark of the experimental run. Then, after a 3 minute time delay, 50 \iL of the capsaicin solution was added at the 190 second time mark (0.05 uM final concentration)(final volume - 200 uL) to challenge the VR1 receptor. Time length of the experimental run was 240 seconds. Fluorescence readings were made at 1 to 5 second intervals over the course of the experimental run. The peak increase in relative fluorescence units (minus baseline) was calculated from the 190 second time mark to the end of the experimental run, and expressed as a percentage of the 0.05 uM capsaicin (control) response. Curve-fits of the data were solved using a four-parameter logistic Hill equation in GraphPad Prism® (GraphPad Software, Inc., San Diego, CA), and ICJO values were calculated.
The compounds of the present invention were found to be antagonists of the vanilloid receptor subtype 1 (VR1) receptor with ICso» from about 2200 nM to about 1.0 nM. In a preferred range, compounds tested had ICsos from about 200 nM to about 1.0 nM.
(b) In Vfvo Data - Determination of Antinociceptive Effect
Experiments were performed on 400 adult male 129J mice (Jackson Laboratories, Bar Harbor, ME), weighing 20-25 g and male Sprague-Dawley rats (Charles River, Wilmington, MA) weighing 200-300 grams were utilized. Animals were kept in a vivarium, maintained at 22 °C, with a 12 hour alternating light-dark cycle with food and water available ad libitum. All experiments were performed during the light cycle. Animals were randomly divided into separate groups of 6 animals each. Each animal was used in one experiment only and was sacrificed immediately following the completion of the experiment. All animal handling and experimental procedures were approved by an IACUC Committee.
The antinociceptive test used was a modification of the abdominal constriction assay described in Collier, et al, Br. J. Pharmacol. Chemother. Vol. 32 pages 295-310, (1968). Each animal received an intraperitoneal (i.p.) injection of 0.3 mL of 0.6% acetic acid in normal saline to evoke writhing. Animals were placed separately under clear cylinders for the observation and quantification of abdominal constriction. Abdominal constriction was defined as a mild constriction and elongation passing caudally along the abdominal wall, accompanied by a slight twisting of the trunk and followed by bilateral extension of the hind
136
WO 2004/111009 PCMJS2004/018590
limbs. The total number of abdominal constrictions was recorded from 5 to 20 minutes after acetic acid injection. The EDso* were determined based on the i.p. injection.
The other antinociceptive test used was Complete Freund's Adjuvant-induced Thermal Hyperalgesia (CFA) assay described in Pircio et al. Eur J Pharmacol. Vol. 31(21 pages 207-215 (1975). Chronic inflammatory hyperalgesia was induced in one group of rats following the injection of complete Freund's adjuvant (CFA, 50%, 150 ul) into the plantar surface of the right hindpaw 48 hours prior to testing. Thermal nociceptive thresholds were measured in three different groups of rats. The EDsos were determined based on the oral administration.
The compounds of the present invention tested were found to have antinociceptive effects with ED50s from about 1 mg/kg to about 500 mg/kg.
The in vitro and in vivo data demonstrates that compounds of the present invention antagonize the VR1 receptor and are useful for treating pain.
Compounds of the present invention are also useful for ameliorating or preventing additional disorders such as, but not limited to, infammatory thermal hyperalgesia, bladder overactivity, and urinary incontinence as described by Nolano, M. et al., Pain Vol. 81 page 135 (1999); Caterina, M.J. and Julius, D., Annu. Rev. Neurosci. Vol. 24, pages 487-517 (2001); Caterina, M.J. et al, Science Vol. 288 pages 306-313 (2000); Caterina, MJ. et al., Nature Vol. 389 pages 816-824 (1997); Fowler, C.
