Definitions

  • This invention is in the field of pharmaceutical agents and specifically relates to compounds, compositions, uses and methods for treating inflammation-related disorders, including pain.
  • NSAIDs non-steroidal anti- inflammatory drugs
  • aspirin, ibuprofen, and indomethacin are moderately effective against inflammatory pain but they are also renally toxic, and high doses tend to cause gastrointestinal irritation, ulceration, bleeding, increased cardiovascular risk, and confusion.
  • Pain is a perception based on signals received from the environment and transmitted and interpreted by the nervous system (for review, see M. Millan, Prog. Neurobiol. 57:1-164 (1999)).
  • Noxious stimuli such as heat and touch cause specialized sensory receptors in the skin to send signals to the central nervous system ("CNS").
  • This process is called nociception, and the peripheral sensory neurons that mediate it are nociceptors.
  • a person may or may not experience a noxious stimulus as painful. When one's perception of pain is properly calibrated to the intensity of the stimulus, pain serves its intended protective function.
  • tissue damage causes a phenomenon, known as hyperalgesia or pronociception, in which relatively innocuous stimuli are perceived as intensely painful because the person's pain thresholds have been lowered. Both inflammation and nerve damage can induce hyperalgesia.
  • hyperalgesia a phenomenon in which relatively innocuous stimuli are perceived as intensely painful because the person's pain thresholds have been lowered. Both inflammation and nerve damage can induce hyperalgesia.
  • persons afflicted with inflammatory conditions such as sunburn, osteoarthritis, colitis, carditis, dermatitis, myositis, neuritis, inflammatory bowel disease, collagen vascular diseases (which include rheumatoid arthritis and lupus) and the like, often experience enhanced sensations of pain.
  • BK and kallidin the active peptides, BK and kallidin, are quickly degraded by peptidases in the plasma and other biological fluids and by those released from a variety of cells, so that the half-life of BK in plasma is reported to be approximately 17 seconds (1).
  • BK and kallidin are rapidly metabolized in the body by carboxypeptidase N, which removes the carboxyterminal arginine residue to generate des-Arg BK or des-Arg kallidin.
  • Des-Arg-kallidin is among the predominant kinins in man and mediate the pathophysiological actions of kinins in man.
  • des-Arg-BK or des-Arg-kallidin is known to induce vasodilation, vascular permeability, and bronchoconstriction (for review, see Regoli and Barabe, Pharmacological Rev, 32(1), 1-46 (1980)).
  • des-Arg-BK and des-Arg-kallidin appear to be particularly important mediators of inflammation and inflammatory pain as well as being involved in the maintenance thereof.
  • Bl and B2 The membrane receptors that mediate the pleiotropic actions of kinins are of two distinct classes, designated Bl and B2. Both classes of receptors have been cloned and sequenced from a variety of species, including man (Menke, et al, J. Biol. Chem. 269, 21583- 21586 (1994); Hess et al, Biochem. Biophys. Res. Commun. 184, 260-268 (1992)). They are typical G protein coupled receptors having seven putative membrane spanning regions. In various tissues, BK receptors are coupled to every known second messenger. B2 receptors, which have a higher affinity for BK, appear to be the most prevalent form of bradykinin receptor. Essentially all normal physiological responses and many pathophysio-logical responses to bradykinin are mediated by B2 receptors.
  • Bl receptors have a higher affinity for des-Arg-BK compared with
  • BK whereas des-Arg-BK is inactive at B2 receptors.
  • Bl receptors are not normally expressed in most tissues. Their expression is induced upon injury or tissue damage as well as in certain kinds of chronic inflammation or systemic insult (F. Marceau, et al.,
  • LPS inflammatory cytokines
  • B 1 receptors inflammatory cytokines
  • the pain-inducing properties of kinins coupled with the inducible expression of B 1 receptors make the Bl receptor an interesting target in the development of anti-inflammatory, antinociceptive, antihyperalgesic and analgesic agents that may be directed specifically at injured tissues with minimal actions in normal tissues.

Description

SUBSTITUTED SULFONAMIDOPROPIONAMIDES AND METHODS OF USE
BACKGROUND OF THE INVENTION
Field of the Invention
This invention is in the field of pharmaceutical agents and specifically relates to compounds, compositions, uses and methods for treating inflammation-related disorders, including pain.
State of the Art
More than two million people in the United States alone are incapacitated by chronic pain on any given day (T. Jessell & D. Kelly, Pain and Analgesia in PRINCIPLES OF NEURAL SCIENCE, third edition (E. Kandel, J. Schwartz, T. Jessell, eds., (1991)). Unfortunately, current treatments for pain are only partially effective, and many cause lifestyle altering, debilitating, and/or dangerous side effects. For example, non-steroidal anti- inflammatory drugs ("NSAIDs") such as aspirin, ibuprofen, and indomethacin are moderately effective against inflammatory pain but they are also renally toxic, and high doses tend to cause gastrointestinal irritation, ulceration, bleeding, increased cardiovascular risk, and confusion. Patients treated with opioids frequently experience confusion and constipation, and long-term opioid use is associated with tolerance and dependence. Local anesthetics such as lidocaine and mixelitine simultaneously inhibit pain and cause loss of normal sensation. In addition, when used systemically, local anesthetics are associated with adverse cardiovascular effects. Thus, there is currently an unmet need in the treatment of chronic pain.
Pain is a perception based on signals received from the environment and transmitted and interpreted by the nervous system (for review, see M. Millan, Prog. Neurobiol. 57:1-164 (1999)). Noxious stimuli such as heat and touch cause specialized sensory receptors in the skin to send signals to the central nervous system ("CNS"). This process is called nociception, and the peripheral sensory neurons that mediate it are nociceptors. Depending on the strength of the signal from the nociceptor(s) and the abstraction and elaboration of that signal by the CNS, a person may or may not experience a noxious stimulus as painful. When one's perception of pain is properly calibrated to the intensity of the stimulus, pain serves its intended protective function. However, certain types of tissue damage cause a phenomenon, known as hyperalgesia or pronociception, in which relatively innocuous stimuli are perceived as intensely painful because the person's pain thresholds have been lowered. Both inflammation and nerve damage can induce hyperalgesia. Thus, persons afflicted with inflammatory conditions, such as sunburn, osteoarthritis, colitis, carditis, dermatitis, myositis, neuritis, inflammatory bowel disease, collagen vascular diseases (which include rheumatoid arthritis and lupus) and the like, often experience enhanced sensations of pain. Similarly, trauma, surgery, amputation, abscess, causalgia, collagen vascular diseases, demyelinating diseases, trigeminal neuralgia, cancer, chronic alcoholism, stroke, thalamic pain syndrome, diabetes, herpes infections, acquired immune deficiency syndrome ("AIDS"), toxins and chemotherapy cause nerve injuries that result in pain.
As the mechanisms by which nociceptors transduce external signals under normal and hyperalgesic conditions become better understood, processes implicated in hyperalgesia can be targeted to inhibit the lowering of the pain threshold and thereby lessen the amount of pain experienced.
Bradykinin (BK) and the related peptide, kallidin (Lys-BK) mediate the physiological actions of kinins on the cardiovascular and renal systems. However, the active peptides, BK and kallidin, are quickly degraded by peptidases in the plasma and other biological fluids and by those released from a variety of cells, so that the half-life of BK in plasma is reported to be approximately 17 seconds (1). BK and kallidin are rapidly metabolized in the body by carboxypeptidase N, which removes the carboxyterminal arginine residue to generate des-Arg BK or des-Arg kallidin. Des-Arg-kallidin is among the predominant kinins in man and mediate the pathophysiological actions of kinins in man. In addition to being a very potent proinflammatory peptide, des-Arg-BK or des-Arg-kallidin is known to induce vasodilation, vascular permeability, and bronchoconstriction (for review, see Regoli and Barabe, Pharmacological Rev, 32(1), 1-46 (1980)). In addition, des-Arg-BK and des-Arg-kallidin appear to be particularly important mediators of inflammation and inflammatory pain as well as being involved in the maintenance thereof. There is also a considerable body of evidence implicating the overproduction of des-Arg-kallidin in conditions in which pain is a prominent feature such as septic shock, arthritis, angina, and migraine.
The membrane receptors that mediate the pleiotropic actions of kinins are of two distinct classes, designated Bl and B2. Both classes of receptors have been cloned and sequenced from a variety of species, including man (Menke, et al, J. Biol. Chem. 269, 21583- 21586 (1994); Hess et al, Biochem. Biophys. Res. Commun. 184, 260-268 (1992)). They are typical G protein coupled receptors having seven putative membrane spanning regions. In various tissues, BK receptors are coupled to every known second messenger. B2 receptors, which have a higher affinity for BK, appear to be the most prevalent form of bradykinin receptor. Essentially all normal physiological responses and many pathophysio-logical responses to bradykinin are mediated by B2 receptors.
Bl receptors, on the other hand, have a higher affinity for des-Arg-BK compared with
BK, whereas des-Arg-BK is inactive at B2 receptors. In addition, Bl receptors are not normally expressed in most tissues. Their expression is induced upon injury or tissue damage as well as in certain kinds of chronic inflammation or systemic insult (F. Marceau, et al.,
Immunopharmacology, 30, 1-26 (1995)). Furthermore, responses mediated by Bl receptors are up-regulated from a null level following administration of bacterial lipopolysaccharide
(LPS) or inflammatory cytokines in rabbits, rats, and pigs. The pain-inducing properties of kinins coupled with the inducible expression of B 1 receptors make the Bl receptor an interesting target in the development of anti-inflammatory, antinociceptive, antihyperalgesic and analgesic agents that may be directed specifically at injured tissues with minimal actions in normal tissues.
Certain compounds have been described as bradykinin antagonists. WO 03/07958, published 30 Jan. 2003, describes tetrahydroquinoxalines. Dihydroquinoxalinones are described in a JACS communication.
Piperazine-2,3,5-triones are described in Tet. Lett., 40, 7557-7560 (1999). European application 641779, published 8 Mar. 1995, describes 3,6-dioxopiperazines as platelet aggregation inhibitors. Clearly, there is a need for new, safe and effective treatments for inflammation and pain. Such agents are provided in the present invention.

The terms "carboxy" or "carboxyl" denotes -CO2H.
The term "carbonyl" denotes -(C=O)-.
The term "comprising" is meant to be open ended, including the indicated component but not excluding other elements. The specification and claims contain listing of species using the language "selected from . . . and . . ." and "is . . . or . . ." (sometimes referred to as Markush groups). When this language is used in this application, unless otherwise stated it is meant to include the group as a whole, or any single members thereof, or any subgroups thereof. The use of this language is merely for shorthand purposes and is not meant in any way to limit the removal of individual elements or subgroups from the genus.

"A pharmaceutically acceptable carrier/excipient" as used in the specification and claims includes both one and more than one such excipient.
The phrase "therapeutically-effective" is intended to qualify the amount of each agent, which will achieve the goal of improvement in disorder severity and the frequency of incidence over treatment of each agent by itself, while avoiding adverse side effects typically associated with alternative therapies. For example, effective pain therapeutic agents relieve the pain sensation of the patient. Alternatively, effective therapeutic agents for the treatment of inflammation minimize the damage from the inflammation, and the like.
The term "treatment" includes therapeutic treatment as well as prophylactic treatment (either preventing the onset of disorders altogether or delaying the onset of a pre-clinically evident stage of disorders in individuals).
The compounds of this invention may also be represented in multiple tautomeric forms, for example, as illustrated below:
The invention expressly includes all tautomeric forms of the compounds described herein. The compounds may also occur in cis- or trans- or E- or Z- double bond isomeric forms. All such isomeric forms of such compounds are expressly included in the present invention. All crystal forms of the compounds described herein are expressly included in the present invention.
Substituents on ring moieties (e.g., phenyl, thienyl, etc.) may be attached to specific atoms, whereby they are intended to be fixed to that atom, or they may be drawn unattached to a specific atom, whereby they are intended to be attached at any available atom that is not already substituted by an atom other than H (hydrogen). The compounds of this invention may contain heterocyclic ring systems attached to another ring system. Such heterocyclic ring systems may be attached through a carbon atom or a heteroatom in the ring system.
Compounds of the present invention can possess, in general, one or more asymmetric carbon atoms and are thus capable of existing in the form of optical isomers as well as in the form of racemic or non-racemic mixtures thereof. Unless otherwise indicated, the compounds of the present invention, as depicted or named, may exist as the racemate, a single enantiomer, or any uneven (i.e. non 50/50) mixture of enantiomers. All such isomeric forms are within the scope of the invention. The optical isomers can be obtained by resolution of the racemic mixtures according to conventional processes, e.g., by formation of diastereoisomeric salts, by treatment with an optically active acid or base. Examples of appropriate acids are tartaric, diacetyltartaric, dibenzoyltartaric, ditoluoyltartaric, and camphorsulfonic acid and then separation of the mixture of diastereoisomers by crystallization followed by liberation of the optically active bases from these salts. A different process for separation of optical isomers involves the use of a chiral chromatography column, such as, for example, a CHIRAL-AGP column, optimally chosen to maximize the separation of the enantiomers. Still another available method involves synthesis of covalent diastereoisomeric molecules by reacting compounds of the invention with an optically pure acid in an activated form or an optically pure isocyanate. The synthesized diastereoisomers can be separated by conventional means such as chromatography, distillation, crystallization or sublimation, and then hydrolyzed to deliver the enantiomerically pure compound. The optically active compounds of the invention can likewise be obtained by using optically active starting materials. These isomers may be in the form of a free acid, a free base, an ester or a salt. Preferred compounds of the invention have an R configuration at the carbon that is attached to the amide bond as shown below:
Compounds of the present invention can possess, in general, tautomeric forms, including any enolate anions. All such forms are included within the scope of this invention.

Scheme A
Compounds of Formula (I) where R1, R2, Rla, Rlb, Rlc, R4 and R5 are as defined in the
Summary of the Invention can be prepared as shown in Scheme A above. Reaction of a sulfonyl chloride of formula 1 where R2 is as defined in the Summary of the Inventio with a β- amino acids of formula 2 provides a compound of formula 3. The reaction is carried out in the presence of a base such as triethylamine, pyridine, and the like and in a suitable organic solvent such as tetrahydrofuran, dimethylformamide and the like, or in the presence of inorganic base such as sodium bicarbonate and sodium carbonate, and the like and in a suitable solvent system such as dioxane/water (1/1, v/v). Alternatively, the reaction can be carried out in neat base. Compounds of formula 1 are either commercially available or they can be prepared by methods well known in the art. Compounds of formula 2 are either commercially available or they can be prepared by methods well known in the art. Reaction of acid 3 with an amine of formula 4 where R4 and R5 are as defined in the Summary of the invention under standard peptidic coupling reaction conditions provide a compound of Formula (I). The reaction is carried out in the presence of a coupling agent such as are coupled with the substituted amine 2 using standard peptide coupling conditions coupling agent (e.g., benzotriazol-1-yloxy- trispyrrolidinophosphonium hexafluorophosphate (PyBOP®.), l-(3-dimethylamino-propyl)-3- ethylcarbodiimide hydrochloride (EDCI), CKT-azabenzotrizol-l-yl)-!,!^^, tetra- methyluroriium-hexafluoro- phosphate (HATU), O-berizotriazol-l-yl-N,N,N,N-tetramethyl- uronium hexafluorophosphate (HBTU), l^-dicyclohexylcarbodiimide (DCC), or the like) and optionally an appropriate catalyst (e.g., 1-hydroxybenzotriazole (HOBt), l-hydroxy-7- azabenzotriazole (HOAt), or the like) and non-nucleophilic base (e.g., triethylamine, N- methylmorpholine, and the like, or any suitable combination thereof) at ambient temperature. Suitable reaction solvents include, but are not limited to, dimethylformamide, methylene chloride, and the like.
Amines of formula 2 are commercially available or may be prepared by methods well known in the art. A detailed description of syntheses of amines is provided in working examples below.
Alternatively, the compounds of Formula (I) can be prepared as shown in Scheme B below.
Scheme B
RV
(I) Compounds of Formula (I) can also be prepared by reacting compound 3 with a an amine of formula 5 where PG is a precursor group to R5 group. Conversion of the PG group to R5 group then provides a compound of Formula (I).
For example, a compound of Formula (I) where R5 is a saturated, partially saturated or unsaturated 8-, 9-, 10- or 11-membered bicyclic or 12-, 13-, 14- or 15- membered tricyclic ring substituted with cycloalkylamino-(Ci-C6)alkyl, cycloalkyl(Ci-C6)alkylamino(Ci-C6)alkyl, heterocyclylamino(C i -Ce)alkyl, heterocyclyl(C i -C6)alkylamino(C i -Cό)alkyl, arylamino(C i -C6)alkyl, aryl(C i -C6)alkylamino-(C i -Ce)alkyl, (C i -C6)alkylamino(C i -C6)alkoxy, (C i -C6)alkylamino(Ci -C6)alkoxy(C i -C6)-alkoxy, amino(C i -Ce)alkoxy, amino(C j -C6)alkyl, (Ci-C6)alkylamino(Ci-C6)alkyl, and 5-7 membered nitrogen-containing heterocyclylalkyl can be prepared by from a corresponding compound of formula 6 where PG is a saturated, partially saturated or unsaturated 8-, 9-, 10- or 11-membered bicyclic or 12-, 13-, 14- or 15- membered tricyclic ring substituted with a hydroxyalkyl group by treating the hydroxyalkyl compound with an oxidizing agent such as manganese oxide and treating the resulting aldehyde compound with an amine optionally substituted with cycloalkyl, cycloalkylalkyl, heterocyclyl, alkyl, aryl, aralkyl, or nitrogen containing heterocyclyl group under reductive amination reaction conditions to provide a compound of Formula (I) with the above listed substitutents. Alternatively, the aldehyde can first treated with an unsubstituted amine and then the amine can be alkylation under standard alkylation reaction conditions or treated with an aldehyde under reductive amination reaction conditions. The above compounds can also be prepared from a corresponding compound of formula 6 carrying an alkene group by first converting the alkyne group to an aldehyde under ozonolysis reaction conditions and then proceeding as described above.
Additionally, the aldehyde can be first converted to a ketone by treating it with a Grignard reagent and then reacted with amine to provide compounds of Formula (I) where the carbon atom alpha to the amino group is substituted.
Compounds of Formula (I) where R5 is a saturated, partially saturated or unsaturated 8-, 9-, 10- or 11-membered bicyclic or 12-, 13-, 14- or 15- membered tricyclic ring substituted with 5-6 membered heterocyclyloxy can be prepared from a corresponding compound of formula 6 where PG is a saturated, partially saturated or unsaturated 8-, 9-, 10- or 11-membered bicyclic or 12-, 13-, 14- or 15- membered tricyclic ring substituted with a hydroxyl group by reacting it with heterocyclyl halide under alkylating reaction conditions. It will be well recognized by a person skilled in the art that if one or more functional groups, for example carboxy, hydroxy, amino, or mercapto, need to be protected during the synthesis of a compound of Formula (I) because they should not take part in the reaction such groups should be suitably protected prior to or during the synthesis procedure. A person skilled in the art would be able to easily establish, which protecting groups are suitable with the reactions mentioned above and hereinafter.
Salts of a compound of Formula (I) with a salt-forming group may be prepared in a manner known per se. Acid addition salts of compounds of Formula (I) may thus be obtained by treatment with an acid or with a suitable anion exchange reagent. A salt with two acid molecules (for example a dihalogenide of a compound of Formula (I)) may also be converted into a salt with one acid molecule per compound (for example a monohalogenide); this may be done by heating to a melt, or for example by heating as a solid under a high vacuum at elevated temperature, for example from 130-170 0C, one molecule of the acid being expelled per molecule of a compound of Formula (I). Salts can usually be converted to free compounds, e.g. by treating with suitable basic agents, for example with alkali metal carbonates, alkali metal hydrogen carbonates, or alkali metal hydroxides, typically potassium carbonate or sodium hydroxide.
The compounds of Formula (I), including their salts, are also obtainable in the form of hydrates, or their crystals can include for example the solvent used for crystallization (present as solvates). All such forms are within the scope of this invention.
As can be appreciated by the skilled artisan, the above synthetic schemes are not intended to comprise a comprehensive list of all means by which the compounds described and claimed in this application may be synthesized. Further methods will be evident to those of ordinary skill in the art. Additionally, the various synthetic steps described above may be performed in an alternate sequence or order to give the desired compounds.

The amount of compounds which are administered and the dosage regimen for treating a disease condition with the compounds and/or compositions of this invention depends on a variety of factors, including the age, weight, sex and medical condition of the subject, the type of disease, the severity of the disease, the route and frequency of administration, and the particular compound employed. Thus, the dosage regimen may vary widely, but can be determined routinely using standard methods. A daily dose of about 0.01 to 500 mg/kg, preferably between about 0.1 and about 50 mg/kg, and more preferably about 0.1 and about 20 mg/kg body weight may be appropriate. The daily dose can be administered in one to four doses per day.
For therapeutic purposes, the active compounds of this invention are ordinarily combined with one or more adjuvants appropriate to the indicated route of administration. If administered per os, the compounds may be admixed with lactose, sucrose, starch powder, cellulose esters of alkanoic acids, cellulose alkyl esters, talc, stearic acid, magnesium stearate, magnesium oxide, sodium and calcium salts of phosphoric and sulfuric acids, gelatin, acacia gum, sodium alginate, polyvinylpyrrolidone, and/or polyvinyl alcohol, and then tableted or encapsulated for convenient administration. Such capsules or tablets may contain a controlled- release formulation as may be provided in a dispersion of active compound in hydroxypropylmethyl cellulose.
In the case of psoriasis and other skin conditions, it may be preferable to apply a topical preparation of compounds of this invention to the affected area two to four times a day. Formulations suitable for topical administration include liquid or semi-liquid preparations suitable for penetration through the skin (e.g. , liniments, lotions, ointments, creams, or pastes) and drops suitable for administration to the eye, ear, or nose. A suitable topical dose of active ingredient of a compound of the invention is 0.1 mg to 150 mg administered one to four, preferably one or two times daily. For topical administration, the active ingredient may comprise from 0.001% to 10% w/w, e.g., from 1% to 2% by weight of the formulation, although it may comprise as much as 10% w/w, but preferably not more than 5% w/w, and more preferably from 0.1% to 1% of the formulation.
When formulated in an ointment, the active ingredients may be employed with either paraffinic or a water-miscible ointment base. Alternatively, the active ingredients may be formulated in a cream with an oil-in-water cream base. If desired, the aqueous phase of the cream base may include, for example at least 30% w/w of a polyhydric alcohol such as propylene glycol, butane- 1,3-diol, mannitol, sorbitol, glycerol, polyethylene glycol and mixtures thereof. The topical formulation may desirably include a compound which enhances absorption or penetration of the active ingredient through the skin or other affected areas. Examples of such dermal penetration enhancers include DMSO and related analogs.
The compounds of this invention can also be administered by a transdermal device. Preferably transdermal administration will be accomplished using a patch either of the reservoir and porous membrane type or of a solid matrix variety. In either case, the active agent is delivered continuously from the reservoir or microcapsules through a membrane into the active agent permeable adhesive, which is in contact with the skin or mucosa of the recipient. If the active agent is absorbed through the skin, a controlled and predetermined flow of the active agent is administered to the recipient. In the case of microcapsules, the encapsulating agent may also function as the membrane.
The oily phase of the emulsions of this invention may be constituted from known ingredients in a known manner. While the phase may comprise merely an emulsifier, it may comprise a mixture of at least one emulsifier with a fat or an oil or with both a fat and an oil. Preferably, a hydrophilic emulsifier is included together with a lipophilic emulsifier which acts as a stabilizer. It is also preferred to include both an oil and a fat. Together, the emulsifier(s) with or without stabilizer(s) make-up the so-called emulsifying wax, and the wax together with the oil and fat make up the so-called emulsifying ointment base which forms the oily dispersed phase of the cream formulations. Emulsifϊers and emulsion stabilizers suitable for use in the formulation of the present invention include Tween 60, Span 80, cetostearyl alcohol, myristyl alcohol, glyceryl monostearate, sodium lauryl sulfate, glyceryl distearate alone or with a wax, or other materials well known in the art. The choice of suitable oils or fats for the formulation is based on achieving the desired cosmetic properties, since the solubility of the active compound in most oils likely to be used in pharmaceutical emulsion formulations is very low. Thus, the cream should preferably be a non-greasy, non-staining and washable product with suitable consistency to avoid leakage from tubes or other containers. Straight or branched chain, mono- or dibasic alkyl esters such as di- isoadipate, isocetyl stearate, propylene glycol diester of coconut fatty acids, isopropyl myristate, decyl oleate, isopropyl palmitate, butyl stearate, 2-ethylhexyl palmitate or a blend of branched chain esters may be used. These may be used alone or in combination depending on the properties required. Alternatively, high melting point lipids such as white soft paraffin and/or liquid paraffin or other mineral oils can be used. Formulations suitable for topical administration to the eye also include eye drops wherein the active ingredients are dissolved or suspended in suitable carrier, especially an aqueous solvent for the active ingredients. The active ingredients are preferably present in such formulations in a concentration of 0.5 to 20%, advantageously 0.5 to 10% and particularly about 1.5% w/w.
Formulations for parenteral administration may be in the form of aqueous or non¬ aqueous isotonic sterile injection solutions or suspensions. These solutions and suspensions may be prepared from sterile powders or granules using one or more of the carriers or diluents mentioned for use in the formulations for oral administration or by using other suitable dispersing or wetting agents and suspending agents. The compounds may be dissolved in water, polyethylene glycol, propylene glycol, ethanol, corn oil, cottonseed oil, peanut oil, sesame oil, benzyl alcohol, sodium chloride, tragacanth gum, and/or various buffers. Other adjuvants and modes of administration are well and widely known in the pharmaceutical art. The active ingredient may also be administered by injection as a composition with suitable carriers including saline, dextrose, or water, or with cyclodextrin (ie. Captisol), cosolvent solubilization (ie. propylene glycol) or micellar solubilization (i.e., Tween 80).
The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally acceptable diluent or solvent, for example as a solution in 1,3- butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution, and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil may be employed, including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid find use in the preparation of injectables.
For pulmonary administration, the pharmaceutical composition may be administered in the form of an aerosol or with an inhaler including dry powder aerosol.
Suppositories for rectal administration of the drug can be prepared by mixing the drug with a suitable non-irritating excipient such as cocoa butter and polyethylene glycols that are solid at ordinary temperatures but liquid at the rectal temperature and will therefore melt in the rectum and release the drug. The pharmaceutical compositions may be subjected to conventional pharmaceutical operations such as sterilization and/or may contain conventional adjuvants, such as preservatives, stabilizers, wetting agents, emulsifiers, buffers etc. Tablets and pills can additionally be prepared with enteric coatings. Such compositions may also comprise adjuvants, such as wetting, sweetening, flavoring, and perfuming agents. While the compounds of the invention can be administered as the sole active pharmaceutical agent, they can also be used in combination with one or more compounds of the invention or other agents. When administered as a combination, the therapeutic agents can be formulated as separate compositions that are administered at the same time or sequentially at different times, or the therapeutic agents can be given as a single composition.
The phrase "co-therapy" (or "combination-therapy"), in defining use of a compound of the present invention and another pharmaceutical agent, is intended to embrace administration of each agent in a sequential manner in a regimen that will provide beneficial effects of the drug combination, and is intended as well to embrace co-administration of these agents in a substantially simultaneous manner, such as in a single capsule having a fixed ratio of these active agents or in multiple, separate capsules for each agent.
The present compounds may also be used in combination therapies with opioids and other anti-pain analgesics, including narcotic analgesics, Mu receptor antagonists, Kappa receptor antagonists, non-narcotic (i.e. non- addictive) analgesics, monoamine uptake inhibitors, adenosine regulating agents, cannabinoid derivatives, Substance P antagonists, neurokinin- 1 receptor antagonists, COX-2 inhibitors such as celecoxib, rofecoxib, valdecoxib, parecoxib, and darecoxib, NSAID's, and sodium channel blockers, among others. More preferred would be combinations with compounds selected from morphine, meperidine, codeine, pentazocine, buprenorphine, butorphanol, dezocine, meptazinol, hydrocodone, oxycodone, methadone, tetrahydrocannibinol, pregabalin, Tramadol [(+) enantiomer], DuP 747, Dynorphine A, Enadoline, RP-60180, HN-11608, E-2078, ICI- 204448, acetominophen (paracetamol), propoxyphene, nalbuphine, E-4018, filenadol, mirtentanil, amitriptyline, DuP631, Tramadol [(-) enantiomer], GP-531, acadesine, AKI-I, AKI-2, GP- 1683, GP-3269, 4030W92, tramadol racemate, Dynorphine A, E-2078, AXC3742, SNX-111, ADL2-1294, ICI- 204448, CT-3, CP-99,994, and CP-99,994.

Synthesis of (5(/?)-amino-5,6,7,8-tetrahydronaphthalen-2-yl)methanol
Step A: Synthesis of 5(iS)-hydroxy-5,6,7,8-tetrahydro-naphthalene-2-carboxylic acid methyl ester
To an oven-dried 2 L round-bottomed flask equipped with an argon inlet/outlet and magnetic stirring was added (i?)-2-methyl-CBS-oxazaborolidine (7.4 mL of a IM soln in toluene, 7.4 mmol, Aldrich). Toluene (190 mL) was added and the reaction mixture was cooled in an ice-salt bath (bath temp. = -10 0C). BH3-SMe2 was added (17 mL, 180 mmol, Aldrich), followed by a solution of 5-oxo-5,6,7,8-tetrahydronaphthalene-2-carboxylic acid methyl ester (30 g, 150 mmol, Albany Molecular) in THF (200 mL) was added over 5 h using a syringe pump. After the addition was complete, the reaction mixture was stirred for an additional 1 h. The reaction mixture was poured into an addition funnel, and the reaction mixture was added to MeOH (200 mL), cooled in a ice-salt bath, over 30 min at such a rate that the internal temp, was kept below 0 0C. The reaction mixture was concentrated in vacuo. Et2O (1 L) was added, and the mixture was washed with IM H3PO4 (3χ), satd NaHCO3, and brine (ca. 400 mL each wash). The organic layer was dried over MgSO4, filtered and concentrated in vacuo. The residue was dissolved in Et2O again (500 mL), and the mixture was washed with IM H3PO4 (3 x 200 mL), satd NaHCO3, and brine. After drying the organic layer over MgSO4, the mixture was filtered and concentrated in vacuo, which gave the title compound as a white-yellow solid. MS (+ ion ESI) m/z = 207 (MH+), 189 (MH+-H2O).

The reaction mixture was cooled in a ice-salt bath, and DPPA (36 mL, 170 mmol, Aldrich) was added (internal temp. = -4 0C). DBU (25 mL, 170 mmol, Aldrich) was added over 10 min at such a rate that the internal temp, of the reaction was kept below 1 0C. The ice in the bath was allowed to melt, and the reaction continued for 12 h during which time the reaction mixture stopped stirring because a precipitate had formed. Stirring was resumed, and the reaction mixture was stirred at RT for another H h. The reaction contents were poured into a 2 L sep funnel, and the lower dark-brown layer was removed. Water (250 mL) was added to the remaining top layer, and the reaction mixture was extracted with Et2O (3 x 250 mL). The combined organic layers were washed with IM H3PO4, water, satd NaHCO3, and brine. The organic layer was dried over MgSO4, filtered and concentrated in vacuo. Purification by silica gel chromatography (330 g Isco Redisep column, 1 : 1 hexane-CH2Cl2) of the crude material provided the title compound. MS (+ ion ESI) m/z = 232 (MH+).

The reaction mixture was cooled in a ice-salt bath, and 5-azido-5,6,7,8-tetrahydronaphthalene-2-carboxylic acid methyl ester (27 g, 120 mmol) in THF (100 mL) was added over ca. 30 min. The reaction mixture was warmed to RT overnight, then cooled in an ice-salt bath the next morning. Water (18 mL) in THF (20 mL) was added to the reaction mixture over 4 h. Vigorous gas evolution occurred. 5N NaOH (18 mL) was added over 30 min followed by water (54 mL). After stirring for an additional 1 h, the reaction mixture was filtered, and the filtrate was concentrated in vacuo. The residue was reconstituted in MeOH and CH3CN, and concentrated in vacuo again to provide the title compound as light-brown solid. MS (+ ion ESI) m/z = 161 (M-NH3). Similarly (4-(i?)-aminochroman-7-yl)-methanol and (l-(/f)-aminoindan-5-yl)methanol were prepared.

Synthesis of (S)-N-((R)-6-(\ -(cyclopropylamino)ethyl)- 1 ,2,3,4-tetrahydronaphthalen- 1 -yl)-3- (3-(trifluoromethyl)phenylsulfonamido)butanamide
Step A: Synthesis of [6-(l-hydroxy-ethyl)-l,2,3,4-tetrahydro-naphthalen-l-yl]-carbamic acid tert-butyl ester
To a solution of (6-formyl-l,2,3,4-tetrahydro-naphthalen-l-yl)-carbamic acid tert-butyl ester (2.80 g, 10.2 mmol, 1.0 eq) in THF (100 mL) at -78 0C was added a solution of MeMgBr [Aldrich, 1.4M in toluene/THF (3:1), 29 mL, 40.7 mmol, 4.0 eq] slowly. The reaction mixture was stirred at -78 0C for 20 min, warmed up to room temperature and stirred at room temperature for 2 h. The reaction was quenched with saturated NaHCO3 (120 mL), and the crude product was extracted with EtOAc (100 mL x 3). The extract phase was washed with saturated NaCl, dried over Na2SO4, filtered and concentrated. The title compound was obtained as a white solid. MS (ESI, pos. ion) m/z: 292 (M+l).
Ill Step B: Synthesis of (6-acetyl-l,2,3,4-tetrahydro-naphthalen-l-yl)-carbamic acid tert-butyl ester
A mixture of [6-(l-hydroxy-ethyl)-l,2,3,4-tetrahydro-naphthalen-l-yl]-carbamic acid tert-butyl ester (2.63 g, 9.04 mmol, 1.0 eq) and MnO2 (Aldrich, 10.2 g, 117.5 mmol, 13 eq) in CH2Cl2 (100 mL) was stirred at room temperature overnight. The reaction mixture was allowed to pass through a pad of Celite and the pad was washed with CH2Cl2 (100 mL x 2). The concentration of the filtrate afforded the title compound as a white sticky semi-solid (1.89 g). MS (ESI, pos. ion) m/z: 290 (M+l). Step C: Synthesis of (,S)-N-((/?)-6-acetyl-l,2,3,4-tetrahydronaphthalen-l-yl)-3-(3- (trifluoromethyl)phenylsulfonamido)butanamide
A mixture of (6-acetyl-l,2,3,4-tetrahydro-naphthalen-l-yl)-carbamic acid tert-butyl ester (650 mg, 2.25 mmol, 1.0 eq) in HCl/EtOAc (4.7M, 20 mL) was stirred at room temperature for 3 h, 20 min. The solvent was removed with a rotary evaporator, and the resulting l-(5-amino-5,6,7,8-tetrahydro-naphthalen-2-yl)-ethanone hydrogen chloride was dried in vacuo. To the flask was added (S)-3-(3-(trifluoromethyl)phenylsulfonamido)butanoic acid (840 mg, 2.7 mmol, 1.2 eq), EDCI (Aldrich, 776 mg, 4.05 mmol, 1.8 eq), HOBt (Aldrich, 61 mg, 0.45 mmol, 0.2 eq) and diisobutylethylamine (Aldrich, 582 mg, 4.50 mmol, 2.0 eq) in CH2Cl2 (20 mL) and the reaction mixture was stirred at room temperature overnight. The reaction was quenched with H2O (100 mL). The crude product was extracted with CH2Cl2 (100 mL x 3). The extract phase was washed with saturated NaCl, dried over Na2SO4, filtered and concentrated. Flash column chromatography (silica gel, 0-7 % MeOH-CH2Cl2) afforded the title compound as a white solid. MS (ESI, pos. ion) m/z: 483 (M+l).

Example 1
Radioligand Binding Assay for human Bl and human B2 bradykinin receptor Step 1 Preparation of membranes expressing human Bl bradykinin receptor:
Membranes were prepared from CHO-d'AQN cells stably transfected with human bradykinin Bl receptor cDNA. For large-scale production of membranes, cells were grown in IOOL suspension culture to 1.0E8 cells/mL then harvested using the Viafuge at continuous centrifugation of 100Qg. For pilot studies, cells were grown in 2 L spinner culture and harvested by centrifugation (1900 g, 10 min, 4 °C). The cell pellet was washed with PBS, centrifuged (1900 g, 10 min, 4 0C), then the cells resuspended in lysis buffer (25 mM HEPES, pH 7.4, 5 mM EDTA, 5 mM EGTA, 3 mM MgCl2, 10% (w/v) sucrose, Complete Protease Inhibitor tablets (EDTA-free)) to a density of 14% w/v for passage through a microfluidizer (Microfluidics 110S, 3 passes, 6,000 psi). The resulting cell lysate was centrifuged (190Og, 10 min, 4 0C), and the crude particulate fraction isolated by centrifugation (142,00Og, 1 h, 4 0C) of the low-speed supernatant. The resulting pellet was resuspended in 1/3 the original lysis buffer volume, homogenized, and recentrifuged as above. The membrane pellet was resuspended by homogenization in storage buffer (25 mM HEPES, pH 7.4, 3 mM MgCl2, 10% (w/v) sucrose and Complete Protease Inhibitor tablets (EDTA-free)). Single-use aliquots were made and flash-frozen in liquid N2 prior to storage at -80 0C.
Membranes containing human bradykinin B2 receptor were purchased from Receptor Biology (now Perkin Elmer Life Sciences). They were derived from a CHO-Kl line stably expressing the human B2 receptor developed by Receptor Biology and subsequently purchased by Amgen. For some studies, membranes were prepared in-house from this same cell line using the method described for human Bl receptor membranes, except cells were grown in roller bottles and harvested using Cellmate.
Step 2 Human Bl receptor binding assay was performed in 96-well polypropylene plates (Costar 3365) by adding 50 μl [3H] des-arg10 kallidin (NET1064; Perkin Elmer Life Sciences) to 10 μL test compound diluted in 90 μL assay buffer (24 mM TES, pH 6.8, 1 mM I5IO o- phenanthroline, 0.3% BSA, 0.5 mM Pefabloc SC, 2 μg/mL aprotinin, 5 μg/mL leupeptin, and 0.7 μg/mL pepstatin A). Membranes (50 μL) were added last. [3H] des-arg10 kallidin was diluted from stock into assay buffer to yield a final concentration of ~0.3nM in the assay but was adjusted as needed to ensure a concentration at or below the Kd determined for each batch of receptor membranes. Nonspecific binding was defined with 2 μM des-Arg10Leu9 kallidin. Membranes were diluted in assay buffer to yield a final concentration of 0.068 nM hBl receptor in the assay. Compounds were solubilized in either DMSO or ddH20, plated into polypropylene plates (Costar 3365), then serially diluted in either DMSO or dilution buffer (20 mM Hepes, pH 7.6, 0.1% BSA) to yield a final concentration of either 5% DMSO or no DMSO in the assay. The assay mixture was incubated with shaking for 1 h at RT and then filtered through GF/C plates presoaked in 0.5% polyethyleneimine (Unifilter; Perkin Elmer Life Sciences) using a Filtermate 96-well harvester (Perkin Elmer Life Sciences). Filter plates were rapidly washed 6 times with 200 μL ice-cold buffer (5OmM Tris, pH 7.4), dried in a vacuum oven at 55 0C for 15-20 min, backed, and 40 μL per well of Microscint 20 was added. The plates were sealed and activity read on Topcount (Perkin Elmer Life Sciences) using a count time of 3 min per channel.
For human B2 bradykinin receptor, the same procedure was followed with the following exceptions: [3H] bradykinin (NET706; Perkin Elmer Life Sciences) was used at a final concentration of ~0.2 nM and non-specific binding was defined with 2 μM bradykinin. Human B2 receptor concentration was 0.068 nM final in the assay. Data analysis
Data was analyzed inΛZFit with the four-parameter logistic y = A + ((B- A)/(l+((C/x)ΛD))) and fit with the Levenburg-Marquardt algorithm. Raw cpm were converted to percent of control values prior to analysis (POC = ((compound cpm - nonspecfic cpm) / (no- compound cpm - nonspecific cpm)* 100)). K1 values were determined from the IC50 using the Cheng-Prusoff equation and Kd values determined by direct saturation binding of the radioligands.
Example 2
In vitro Bl -Inhibition Activity In vitro Assay of human Bl Receptor Function using Calcium Flux
Activation of the Gq linked Bl receptor results in an increase in intracellular calcium. The calcium sensitive photoprotein aequorin can, therefore, be used as an indicator of Bl receptor activation. Aequorin is a 21-kDa photoprotein that forms a bioluminescent complex when linked to the chromophore cofactor coelenterazine. Following the binding of calcium to this complex, an oxidation reaction of coelenterazine results in the production of apoaequorin, coelenteramide, CO2, and light that can be detected by conventional luminometry.
A stable CHO D-/hBl /Aequorin cell line was established and the cells were maintained in suspension in spinner bottles containing a 1 : 1 ratio of DMEM and HAM F 12 (Gibco 11765- 047), high glucose (Gibco 11965-084), 10% Heat Inactivated Dialyzed serum (Gibco 26300- υt>l), lλ Mon-bssential Amino Acids (Gibco 11140-050), IX Glutamine-Pen-Strep (Gibco 10378-016), and Hygromycin, 300 μg/mL (Roche 843555). 15-24 h prior to the luminometer assay, 25,000 cells/well (2.5E6 cells/ 10 mL/plate) were plated in 96- well black-sided clear bottom assay plates (Costar #3904). Media was removed from the wells and replaced with 60 μL of serum free HAM's Fl 2 with 30 mM HEPES (pH 7.5) and 15μM coelenterazine (Coelenterazine h Luciferin #90608 from Assay Designs). The plates were incubated for 1.5-2 h. Ten point IC50 compound plates containing 1:3 or 1:5 dilutions of antagonist compounds and an agonist activator plate (2OnM des-ArglO-Kallidin final concentration, EC8o) were prepared using Ham's Fl 2 with 3OmM HEPES, pH 7.5. Following coelenterazine incubation, an automated flash-luminometer platform was used to dispense the B 1 antagonist compounds (dissolved in DMSO and diluted with buffer to the desired concentration (final DMSO concentration <1% DMSO)) to the cell plate, a CCD camera situated underneath the cell plate took 12 images of the cell plate at 5 second intervals to determine if there was any agonist activity with the compounds. The hBl agonist, des-Argio-Kallidin, was added to the cell plate and another 12 images were recorded to determine the IC50 of the antagonist(s). In vitro Assay of hB2 Receptor Function using Calcium Flux
The intracellular calcium flux induced by hB2 receptor activation was analyzed using an hB2 recombinant cell line (CHO-Kl) purchased from PerkinElmer (Catalog Number: RBHB2C000EA) on a fluorometric imaging plate reader (FLIPR). The cells were cultured in T225 flask containing Ham's Fl 2 Nutrient Mixture (Invitrogen Corp., Cat # 11765-047), 10% Fetal Clone II Bovine Serum (HyClone, Cat # SH3006603), 1 mM Sodium pyruvate (100 mM stock, Invitrogen Corp., Cat# 12454-013), and 0.4 mg/mL Geneticin (G418; 50 mg/mL active geneticin, Invitrogen, Cat# 10131-207). Culture medium was changed every other day. 24 h prior to the FLIPR assay, the hB2/CHO cells were washed once with PBS (Invitrogen) and 10 mL of Versene (1 : 5000, Invitrogen, Cat# 15040-066) was added to each flask. After 5 min incubation at 37 0C, Versene was removed and cells were detached from the flask and resuspended in culture medium. Cells were counted and 25,000 cells/well were plated in 96- well black-sided clear bottom assay plates (Costar #3904). Cells were incubated in a 37 0C CO2 incubator overnight.
The media was aspirated from the cells and replaced with 65 μL of dye-loading buffer. The loading buffer was prepared by diluting a stock solution of 0.5mM Fluo-4 AM (Molecular Probes, dissolved in DMSO containing 10% [w/v] pluronic acid) to a concentration of lμM in Clear Dulbecco's Modified Eagle Medium (DMEM) containing 0.1% BSA, 20 mM HEPES, and 2.5 mM probenecid. The cells were dye-loaded for 1 h at RT. The excess dye was removed by washing the cells 2x with assay buffer. The assay buffer consists of Hank's Balanced Salt Solution (HBSS) containing 20 mM HEPES, 0.1% BSA, and 2.5 mM probenecid. After the wash cycles, a volume of 100 μL was left in each well, and the plate was ready to be assayed in the FLIPR System. Single point (10 μM final concentration) POC antagonist compound plates or ten point IC50 compound plates containing 1 :3 or 1 :5 dilutions of antagonist compounds (dissolved in DMSO and diluted with buffer to the desired concentration (final DMSO concentration <1% DMSO)) and an agonist activator plate (0.3 nM bradykinin final concentration, EC8o) were prepared using assay buffer. The cell plate and the compound plates were loaded onto the FLIPR and during the assay, fluorescence readings are taken simultaneously from all 96 wells of the cell plate. Ten 1 -second readings were taken to establish a stable baseline for each well, then 25 μL from the Bl antagonist plate was rapidly (50 μL/sec.) added. The fluorescence signal was measured in 1 -second (1 min) followed by 6- second (2 min) intervals for a total of 3 min to determine if there is any agonist activity with the compounds. The B2 agonist, bradykinin, was added to the cell plate and another 3 min were recorded to determine the percent inhibition at 10 μM (POC plates) or the IC50 of the antagonist.
Example 3 Cell and Tissue based In Vitro Assays of hBl Receptor Binding These studies established the antagonist activity of several compounds at the bradykinin Bl receptors in in vitro cell-based and isolated organ assays.
1. Rabbit endothelial cell B 1 -specific PGI2 secretion Assay
2. Bl and B2 umblical vein Assay In vitro Bl -Inhibition Activity: The effectiveness of the compounds as inhibitors of B 1 activity (i.e., B 1
"neutralization") can be evaluated by measuring the ability of each compound to block B 1 stimulated CGRP and substance P release and calcium signaling in Dorsal Root Ganglion (DRG) neuronal cultures. Dorsal Root Ganglion Neuronal Cultures: Dorsal root ganglia are dissected one by one under aseptic conditions from all spinal segments of embryonic 19-day old (E 19) rats that are surgically removed from the uterus of timed-pregnant, terminally anesthetized Sprague-Dawley rats (Charles River, Wilmington, MA). DRG are collected in ice-cold L-15 media (GibcoBRL, Grand Island, NY) containing 5% heat inactivated horse serum (GibcoBRL), and any loose connective tissue and blood vessels are removed. The DRG are πnsed twice in Ca2+- and Mg2+-free Dulbecco's phosphate buffered saline (DPBS), pH 7.4 (GibcoBRL). The DRG are dissociated into single cell suspension using a papain dissociation system (Worthington Biochemical Corp., Freehold, NJ). Briefly, DRG are incubated in a digestion solution containing 20 U/mL of papain in Earle's • Balanced Salt Solution (EBSS) at 37 0C for fifty minutes. Cells are dissociated by trituration through fire-polished Pasteur pipettes in a dissociation medium consisting of MEM/Ham's F12, 1: 1, 1 mg/mL ovomucoid inhibitor and 1 mg/mL ovalbumin, and 0.005% deoxyribonuclease I (DNase). The dissociated cells are pelleted at 200 x g for 5 min and re- suspended in EBSS containing 1 mg/mL ovomucoid inhibitor, 1 mg/mL ovalbumin and 0.005% DNase. Cell suspension is centrifuged through a gradient solution containing 10 mg/mL ovomucoid inhibitor, 10 mg/mL ovalbumin at 200 x g for 6 min to remove cell debris, then filtered through a 88-μM nylon mesh (Fisher Scientific, Pittsburgh, PA) to remove any clumps. Cell number is determined with a hemocytometer, and cells are seeded into poly- ornithine 100 μg/mL (Sigma, St. Louis, MO) and mouse laminin 1 μg/mL (GibcoBRL)-coated 96-well plates at 10 x 103 cells/well in complete medium. The complete medium consists of minimal essential medium (MEM) and Ham's F12, 1: 1, penicillin (100 U/mL), streptomycin (100 μg/mL), and 10% heat inactivated horse serum (GibcoBRL). The cultures are kept at 37 0C, 5% CO2 and 100% humidity. For controlling the growth of non-neuronal cells, 5-fluoro- 2'-deoxyuridine (75μM) and undine (180μM) are included in the medium. Two hours after plating, cells are treated with recombinant human β-bl or recombinant rat β-bl at a concentration of 10 mg/ml (0.38 nm). Positive controls comprising serial-diluted anti-bl antibody (r&d systems, minneapolis, mn) are applied to each culture plate. Compounds are added at ten concentrations using 3.16-fold serial dilutions. All samples are diluted in complete medium before being added to the cultures. Incubation time is generally around 40 h prior to measurement of vr 1 expression. Measurement of VRl Expression in DRG Neurons:
Cultures are fixed with 4% paraformaldehyde in Hanks' balanced salt solution for 15 min, blocked with Superblock (Pierce, Rockford, IL), and permeabilized with 0.25% Nonidet P-40 (Sigma) in Tris.HCl (Sigma)-buffered saline (TBS) for 1 h at RT. Cultures are rinsed once with TBS containing 0.1% Tween 20 (Sigma) and incubated with rabbit anti-VRl IgG (prepared at Amgen) for 1.5 h at RT, followed by incubation of Eu-labeled anti-rabbit second antibody (Wallac Oy, Turku, Finland) for 1 h at RT. Washes with TBS (3 x five min with slow shaking) are applied after each antibody incubation. Enhance solution (150 mL/well, Wallac Oy) is added to the cultures. The fluorescence signal is measured in a time-resolved πuorometer VΛI expression in samples treated with the compounds is determined by comparing to a standard curve of Bl titration from 0-1000 ng/mL. Percent inhibition (compared to maximum possible inhibition) of Bl effect on VRl expression in DRG neurons is determined by comparing to controls that are not B 1 -treated.
Example 4
In vivo antinociceptive activity in rat and monkey pain models Rat Neuropathic Pain Model
Male Sprague-Dawley rats (200 g) are anesthetized with isoflurane inhalant anesthesia and the left lumbar spinal nerves at the level of L5 and L6 are tightly ligated (4-0 silk suture) distal to the dorsal root ganglion and prior to entrance into the sciatic nerve, as first described by Kim and Chung (Kim, S.H.; Chung, J.M. An experimental model for peripheral neuropathy produced by segmental spinal nerve ligation in the rat. Pain 50:355-363, (1992)). The incisions are closed and the rats are allowed to recover. This procedure results in mechanical (tactile) allodynia in the left hind paw as assessed by recording the pressure at which the affected paw (ipsilateral to the site of nerve injury) was withdrawn from graded stimuli (von Frey filaments ranging from 4.0 to 148.1 mN) applied perpendicularly to the plantar surface of the paw (between the footpads) through wire-mesh observation cages. A paw withdrawal threshold (PWT) was determined by sequentially increasing and decreasing the stimulus strength and analyzing withdrawal data using a Dixon non-parametric test, as described by
Chaplan et al. (Chaplan, S.R.; Bach, F.W.; Pogrel, J.W.; Chung, J.M.; Yaksh, T.L. Quantitative assessment of tactile allodynia in the rat paw. J. Neurosci. Meth., 53:55-63 (1994)).
Normal rats and sham surgery rats (nerves isolated but not ligated) withstand at least 148.1 mN (equivalent to 15 g) of pressure without responding. Spinal nerve ligated rats respond to as little as 4.0 mN (equivalent to 0.41 g) of pressure on the affected paw. Rats are included in the study only if they did not exhibit motor dysfunction (e.g., paw dragging or dropping) and their PWT was below 39.2 mN (equivalent to 4.0 g). At least seven days after surgery rats are treated with compounds (usually a screening dose of 60 mg/kg) or control diluent (PBS) once by s.c. injection and PWT was determined each day thereafter for 7 days. Rat CFA Inflammatory Pain Model
Male Sprague-Dawley rats (200 g) are lightly anesthetized with isoflurane inhalant anesthesia and the left hindpaw is injected with complete Freund's adjuvant (CFA), 0.15 mL. This procedure results in mechanical (tactile) allodynia in the left hind paw as assessed by recording the pressure at which the affected paw is withdrawn from graded stimuli (von Frey tilaments ranging trom 4.0 to 148.1 mN) applied perpendicularly to the plantar surface of the paw (between the footpads) through wire-mesh observation cages. PWT is determined by sequentially increasing and decreasing the stimulus strength and analyzing withdrawal data using a Dixon non-parametric test, as described by Chaplan et al. (1994). Rats are included in the study only if they do not exhibit motor dysfunction (e.g., paw dragging or dropping) or broken skin and their PWT is below 39.2 mN (equivalent to 4.0 g). At least seven days after CFA injection rats are treated with compounds (usually a screening dose of 60 mg/kg) or control solution (PBS) once by s.c. injection and PWT is determined each day thereafter for 7 days. Average paw withdrawal threshold (PWT) is converted to percent of maximum possible effect (%MPE) using the following formula: %MPE = 100 * (PWT of treated rats - PWT of control rats)/(15-PWT of control rats). Thus, the cutoff value of 15 g (148.1 mN) is equivalent to 100% of the MPE and the control response is equivalent to 0% MPE.
At the screening dose of 60 mg/kg, compounds in vehicle are expected to produce an antinociceptive effect with a PD relationship.
Example 5 Green Monkey LPS Inflammation Model
The effectiveness of the compounds as inhibitors of Bl activity are evaluated in Male green monkeys (Cercopithaecus aethiops StKitts) challenged locally with Bl agonists essentially as described by deBlois and Horlick (British Journal of Pharmacology, 132:327-335 (2002), which is hereby incorporated by reference in its entirety).
In order to determine whether compounds of the present invention inhibit Bl induced oedema the studies described below are conducted on male green monkeys {Cercopithaecus aethiops St Kitts) at the Caribbean Primates Ltd. experimental farm (St Kitts, West Indies). Procedures are reviewed and accepted by the Animal Care Committees of the CR-CHUM
(Montreal, Canada) and of Caribbean Primates Ltd. (St Kitts, West Indies). Animals weighing 6.0 ± 0.5 kg (n=67) were anaesthetized (50 mgketamine kg'1) and pretreated with a single intravenous injection of LPS (90 μg kg'1) or saline (1 mL) via the saphenous vein. Inflammation studies Kinin-induced oedema is evaluated by the ventral skin fold assay (Sciberras et al.,
1987). Briefly, anaesthetized monkeys were injected with captopril (1 mg kg"1 30 min before assay). A single subcutaneous injection of dKD, BK or the vehicle (2 mM amastatin in 100 μL Ringer's lactate) is given in the ventral area and the increase in thickness of skin folds is monitored for 30-45 min using a calibrated caliper. The results are expressed as the difference between the skinfold thickness before and after the subcutaneous injection. Captopril and amastatin are used to reduce degradation of kinins at the carboxyl- and amino-terminus, respectively.
Antagonist schild analysis: The dose-response relationship for dKD (1-100 nmol)-induced oedema is determined at
24 h post-LPS in the absence or presence of different concentrations of antagonist. BK (30 nmol) is used as a positive control.
Antagonist time course
The time course of inhibition by antagonist is determined at 4, 24 and 48 h, 72 and/or 96 h after single bolus administration. BK (30 nmol) is used as a positive control.
Drugs
Ketamine hydrochloride, LPS, amastatin and captopril are from Sigma (MO, U.S.A.).
All peptides are from Phoenix Pharmaceuticals (CA, U.S.A.).
Statistics Values are presented as mean ±standard error of the mean (s.e. mean). In edema studies, the pre-injection thickness of the skin folds was subtracted from the values after subcutaneous challenge. Curve fitting and EC50 calculations were obtained using the Delta
Graph 4.0 software for Apple Computers. Data were compared by two-way analysis of variance followed by unpaired, one tail Student's Mest with Bonferroni correction. P <0.05 was considered statistically significant.
