Description

NOVEL BIARYL BENZOIMID AZOLE DERIVATIVES AND PHARMACEUTICAL COMPOSITION COMPRISING THE

SAME

Technical Field

[1] The present invention relates to a novel biaryl benzoimidazole derivative, a method for preparing the same, and a pharmaceutical composition comprising the same, in which the biaryl benzoimidazole derivative functions as an antagonist of the vanilloid receptor (Capsaicin receptor; Transient Receptor Potential Channel, Vanilloid subfamily member 1; TRPV-I; Vanilloid receptor- 1; VR-I). Background Art

[2] The vanilloid receptor, the receptor for capsaicin

(trans-8-methyl-N-vanillyl-6-nonenamide), has long been assumed to exist. Finally, it was cloned in 1997 and called vanilloid receptor subtype 1 (hereinafter referred to as "VR-I") by Caterina et al. (Caterina et al., Nature, 1997, 389, 816). Located on small unmyelinated nerve fibers (C-fibers) and myelinated nerve fibers (A-fibers), VR-I is known as an ion channel which plays an important role in sensitizing pain stimuli by introducing the strong influx of cations such as calcium and sodium ions into the nerve endings upon activation in response to external or internal stimuli. External stimuli capable of activating VR- 1 are reported to include heat and acids as well as vanilloid compounds (Tominaga et al., Neuron, 1998, 21, 531). As internal stimuli to VR-I, there are leukotriene metabolites such as 12-hydroperoxyeicosa tetraenoic acid (12-HPETE) (Hwang at al., PNAS, 2000, 97, 3655), and arachidonic acid derivatives such as anandamide (Premkumar et al., Nature, 2000, 408, 985).

[3] On the basis of these physiological activities, VR-I has attracted intensive attention as an integral controller playing a pivotal role in transferring various external injurable stimuli into nerve cells. According to a report, VR-I knock-out mice responded like normal mice to general stimuli, but showed greatly reduced pain response to heat or thermal hyperalgesia, which reflects the importance of VR- 1 against noxious stimuli (Caterina et al., Science, 2000, 288, 306).

[4] VR-I is concentratively expressed in primary sensory neurons (Caterina et al.,

Nature, 1997, 389, 816), which are responsible for controlling functions of internal organs such as the skin, the bones, the bladder, the gastrointestinal tract, the lungs, and so on. In addition, being distributed in other neurons on the central nervous system, the kidneys, the stomach, and T-cells (Nozawa et al., Neuroscience Letter, 2001, 309, 33; Yiangou et al., Lancet (North America Edition), 2001, 357, 1338 ; Birder et al., PNAS, 2001, 98, 13396) and throughout the entire body, VR-I is inferred to play an important role in cell division and cellular signal control.

[5] Indications found, thus far, to be associated with the control mechanism of the activity of VR- 1 include pain, acute pain, chronic pain, neuropathic pain, postoperative pain, migraines, arthralgia, neuropathy, nerve injury, diabetic neuropathy, neurological illness, neurodermatitis, strokes, bladder hypersensitivity, irritable bowel syndrome, respiratory disorders such as asthma, chronic obstructive pulmonary disease, etc., irritation to the skin, eyes, and mucous membranes, itching, fever, gastric-duodenal ulcer, inflammatory intestinal diseases, and urge incontinence (Korean Pat. Laid-Open Publication No. 10-2004-0034804), and an anti-obestic effect (Pharmacol. Rev., 1986, 38, 179).

[6] Based on pharmaceutical mechanisms, both agonists and antagonists of VR-I may be used for the treatment of the above-mentioned diseases. Pain alleviating effects of VR-I agonists show the pharmaceutical mechanism based on the desensitization of capsaicin-sensitive sensory nerves. That is, VR-I agonists cause pain and irritation of sensory nerves so as to desensitize them to other noxious stimuli. Due to the induction of pain in the early stage, VR-I agonists are developed only as local analgesics. In contrast, acting through the mechanism of blocking sensory nerves from recognizing pain signals, VR-I antagonists do not cause early pain or irritation, and have been studied for use in the treatment of systemic diseases.

[7] As compounds capable of modulating VR-I activity, agonists such as capsaicin,

DA-5018, resiniferatoxin, etc. are used as pain drugs or are under clinical study (Szallasi, J. Med chem., 2004, 47, 2717), while various agonists including amine compounds such as heterocycloalkylbenzoimidazole(WO2004095549), amide(WO03068749, WO2004069792, WO2006006740, WO2006006741, WO2004108133, US20060122231, US20050288281, GB200319150, SE200301246), (thio)urea(WO03080578, WO02072536, WO03022809, WO03055484, WO03029199, WO03053945, WO2004052845, WO2004007459, WO2005014580, US6984647, US7015233, GB200110901, GB200305426, CA2417507, JP2003-055209, KR0556158), quinazoline, heteroaryl etc.(WO03062209, WO2004055003, WO2004055004, WO2004033435, WO05003084, WO2004072068, WO2004002983, WO0208221, WO05009977, WO0216317, US20040157845, US20050113576, US6933311, US7053088, US20060084640, US20060089360, US20060058308, US6974818, GB200107505, GB200326217, GB200407748) as well as capsazepine and iodoresiniferatoxin are under study.

[8] Recently, the present inventors have reported an antagonist having a structure of benzoimidazole as disclosed in WO2006/080821A1, in which the antagonist shows a powerful antagonistic effect on a vanilloid receptor in HEK cells, and a powerful analgesic effect in a writhing test using an animal model.

[133] [134] The biaryl benzoimidazole derivative of Formula 1 of the present invention can be prepared as a pharmaceutically acceptable salt according to a conventional method known in the art. The pharmaceutically acceptable salt is a conventional salt used in the related art such as acid addition salt, and comprises salts described in the article, J.

Pharm. ScL, 1977, 66, 1. The pharmaceutically acceptable acid addition salt include an inorganic acid addition salt prepared with an inorganic acid such as hydrochloric acid, hydrobromic acid, phosphoric acid, ortho-phosphoric acid or sulfuric acid, or an organic acid addition salt prepared with an organic acid such as methanesulfonic acid, benzenesulfonic acid, toluenesulfonic acid, acetic acid, propionic acid, lactic acid, citric acid, fumaric acid, malic acid, succinic acid, salicylic acid, maleic acid, glyc- erophosphoric acid, or acetylsalicylic acid.

[135] Further, a pharmaceutically acceptable metal salt can be prepared using a base. An alkali metal salt and alkaline earth metal salt can be obtained by a method, in which a compound is dissolved in an excessive amount of alkali metal hydroxide or alkaline earth metal hydroxide solution, filtered the undissolved salt, and then the filtrate is evaporated and dried. In respects to metal salts, it is preferable that sodium, potassium, or calcium salt is pharmaceutically preferable, and the corresponding silver salt is obtained by reacting alkali metal salt or alkaline earth metal salt with a suitable silver salt (e.g. nitrate).

[136] A salt and/or solvate of the compound of Formula 1 being not pharmaceutically acceptable can be used as an intermediate in the preparation of a salt and/or solvate of the compound of Formula 1 being pharmaceutically acceptable, or the compound of Formula 1 itself, which forms another aspect of the present invention.

[137] The compound of Formula 1 of the invention can be prepared in a crystalline or noncrystalline form, and in the case of a crystalline form, the compound may be hydrated or solvated. In the scope of the invention, a stoichiometric hydrate as well as a compound containing various amount of water can be included.

[138] The solvate includes a pharmaceutically acceptable solvate such as hydrate. The solvate includes a stoichiometric solvate and a nonstoichiometric solvate.

[139] Further, the biaryl benzoimidazole derivative of Formula 1 of the invention has an asymmetric center, thereby existing in the form of a different enantiomer, and all of the optical isomers, R or S type stereoisomer, and a mixture thereof of the biaryl benzoimidazole derivative of Formula 1 are included in the scope of the invention.

[616] In order to measure an activity of the biaryl benzoimidazole derivative of the invention as an antagonist, a calcium influx test was performed.

[617] 1) Cell culture

[618] An hVRl-HEK293 cell line is a cell line, in which a Human Embryonic Kidney

(HEK) 293 Tet-on cell is transformed with a human vanilloid- 1 gene (pTRE2hyg-hVRl, 7.8kb). The cell line can regulate a VR-I expression, depending on the administration of a tetracycline analogue, doxycycline. At two days before the calcium influx test, the cell line was cultured in media containing doxycycline to induce the VR-I expression, and then used. First, the hVRl-HEK293 cells were cultured in T75 flasks to have a density of about 80%, and then detached from the bottom of the flasks by using trypsin. The detached cells were centrifuged and collected. Then, the cells were suspended in media containing 1 D/mL doxycycline, and diluted to have a concentration of 2x 10 to 4 x 10 cells/mL. 100 μL of the suspended cells were added to each well of 96- well black plate, cultured at 37⁰C and 5% CO cell incubator for two days, and then used in the calcium influx test.

[619] 2) Preparation of sample compound

[620] The compound was dissolved in dimethyl sulfoxide (DMSO), and then used for the calcium influx test.

[621] 3) Calcium influx measurement

[622] In order to measure the calcium influx in vivo, the cells were cultured in a solution containing Fluo-3/AM, which is a calcium indicator, at 37⁰C for 90 minutes, so as to be permeated by a fluorescent dye. Then, the cells were washed with D-PBS (Dulbecco's phosphate buffered saline) containing 10 mM HEPES three times, and the fluorescent dye that did not permeate into the cells was removed. 193 μL D-PBS were added to each well, and then the compound was added thereto in various concentrations. To measure an activity as an antagonist, the cells were treated with 1 μM capsaicin to stimulate the calcium influx. The inhibitory effect of the compound when calcium influx was induced by 1 μM capsaicin was measured depending on its concentration using a fluorescence spectrometer, and the obtained data were substituted into a hill equation to analyze the values.

[623] The results of evaluating the inhibitory effect of the compounds of the invention on calcium influx are shown in Table 1. The inhibitory effect on calcium influx was measured with a single concentration of the compounds of the invention (200 nM), and the result thereof are shown in Table 2.

[624] Table 1 Evaluation result of inhibitory effect of compounds of the invention on calcium influx

Table 2

Evaluation result of inhibitory effect on calcium influx with a single concentration of compounds of the invention (20OnM)

[626] [627] As shown in Tables 1 and 2, it was found that the biaryl benzoimidazole derivative of the invention has an excellent inhibitory effect on calcium influx in HEK cells, thereby showing a powerful antagonistic effect on the vanilloid receptor.

[628] [629] Experimental Example 2: Analgesic efficacy test [630] In order to test analgesic efficacy of the biaryl benzoimidazole derivative of the invention, a PBQ-induced writhing test was performed using a mouse.

[631] A 5-week-old ICR male mouse was used as an experimental animal, and PBQ (phenyl-p-quinone, 0.02%) was used as a chemical stimulator. 20 mg of the test material per mouse body weight were suspended in 10 mL solvent of Na-CMC and saline solution, and then used. At 1 hour before administering PBQ, the test material and excipient were orally administered, and 10 mL of PBQ per kg (body weight) were intraperitoneally administered. Between 5 to 10 minutes after administration, the writhing frequency of each subject of the experimental groups was measured, and for the measurement of the analgesic efficacy, the frequency reduction was calculated as compared to a control group by using Equation 1. The results are shown in Table 3.

[632] [Equation 1] [633] Inhibitory effect (%) = [(a control group administered with excipient - a group administered with test material)/ a control group administered with excipient] x 100

[634] [635] Table 3

[636] [637] As shown in Table 3, the biaryl benzoimidazole derivative of the invention was found to have an excellent analgesic effect. Industrial Applicability

[638] The biaryl benzoimidazole derivative of the present invention has an excellent inhibitory effect on calcium influx in HEK cells, thereby showing a powerful antagonistic effect on a vanilloid receptor, and further has an excellent analgesic effect, thereby being useful for preventing or treating pain, acute pain, chronic pain, neuropathic pain, postoperative pain, migraine, arthralgia, neuropathies, nerve injury, diabetic neuropathy, neurological illness, neurodermatitis, stroke, bladder hypersensitivity, irritable bowel syndrome, a respiratory disorder such as cough, asthma, and chronic obstructive pulmonary disease, burning, psoriasis, itching, vomiting, irritation of the skin, eyes, and mucous membranes, gastric-duodenal ulcers, inflammatory intestinal diseases, and inflammatory diseases.
