       BACKGROUND  
       [0002]    1. Technical Field 
         [0003]    The present invention relates to pyrazolylmethylamine-piperazine derivatives and their pharmaceutically acceptable salts effective as calcium channel modulators and a method of manufacturing the same. The present invention also relates to the pharmaceutical use of the above compounds as therapeutic treatment of diseases due to their effect as calcium channel modulators. 
         [0004]    2. Background Art 
         [0005]    Introduction of calcium ions into cells through a voltage-gated calcium channel has been known to mediate a wide scope of cellular and physiological reactions including secretion of hormones, and gene expression. Since 1950s, the flux of calcium ions, expression and physiological importance of transmembrane have been well perceived, and in 1970s, it was made possible to measure the calcium current under voltage-clamp condition (D. Gedualding, R. Gruener,  J. Physiolo.  1970, 211, 217-244). In 1980s, neuronal calcium channel, depending on the voltage dependence, was divided into two subtypes of high voltage activity (HVA) Ca 2+ channel (L, N, P, Q and R type) and low voltage activity (LVA) (T-, L-type) (R, Llinas, Y. Yarom,  J. Physiolo.  1981, 315, 549-567, E. Carbone, H. D. Lux,  Nature,  1984, 310, 501-502). 
         [0006]    Further, LVA-dependent channel, based on its transient signal, was named as ‘T-type calcium channel’, while HVA-dependent channel, based on its long-lasting signal, was named as ‘L-type calcium channel’. 
         [0007]    The classification of these calcium channels and their systems thereof are as shown below in the Table 1.

         [0008]    As shown in the above Table 1, HVA L-type calcium channel is indicated as α 1S , α 1C , α 1D  and α 1F  (Ca v  1.1-Ca v  1.4) subtypes. 
         [0009]    As shown in the above Table 1, HVA L-type calcium channel is indicated as α 1S , α 1C , α 1D  and α 1F  (Ca v  1.1-Ca v  1.4) subtypes. HVA P-, Q-, N-and R-type calcium channels are indicated as subtypes of (Ca v  2.1), α 1B  (Ca v  2.2), and α 1E  (Ca v  2.3), respectively. 
         [0010]    LVA T-type calcium channels are indicated as subtypes of α 1G , α 1H  and α 1I (Ca v  3.1-Ca v  3.3). Further, these pore-forming a subtypes can bind to other auxiliary subtypes such as α 2  δ, β or γ. 
         [0011]    The above voltage-gated ion channels are very closely associated with secretion of neurotransmitters and are mainly discovered in central nervous system, peripheral nervous system and neuroendocrine cells. 
         [0012]    All channels used and the neurotransmitters system are somehow involved in pain-signal transmission, and T- and N-type calcium channels are becoming a target for the development of a novel anesthesia. 
         [0013]    Pains may be largely divided into acute, chronic and neuropathic pains. Of them, neuropathic pain is initiated or caused by nerve injury, and lesion or dysfunction in the nerves system can result from trauma, viral infection, drug-induced or cancer related condition. It is associated with abnormal sensory phenomena including allododynia and hyperalgesia. It cause sensitization of sensory fibers and awakening of silent nociceptor, and result in reorganization of spinal and cortical circuit which are associated with altered calcium channel expression. Because of the complexity and diversity of the pathophyological mechanisms in neuropathic pain, successful treatment remains difficult to predict and achieve. 
         [0014]    Calcium channels are endogenous modulators and have been studied for their roles in relation to multiple neurotransmitter, hormone drugs, antihypertensive drugs, anesthetic drugs, antiarrhythmic drugs, antiepileptic drugs (A. M. Yunker, M. W. McEnery,  J. Bioeng. Biomembr.  2003, 35, 533). 
         [0015]    Recently, it was shown that N-type (Ca v  2.2) and T-type calcium channels are valuable targets for pain treatment by the approval of Prialt® (Elan Pharmaceuticals), their selective blocker developed as a new synthetic drug (Drug Discovery Today, 2006, 11(5), 245-253). 
         [0016]    In addition, Ca v  2.2 also mediates the release of neurotransmitters from the neurons in the sympathetic nerve system, and antagonists can be used for the treatment of cardiovascular diseases such as hypertension, cardiac arrhythmia, angina pectoris, myocardial infarction and congestive heart failure. 
         [0017]    Further, T-type calcium channel is involved in cell development, differentiation and proliferation, cancer growth, sleep, epilepsy, nociception, pain, neuropathic pain, etc., and thus control of the T-type calcium channel has become a target for the regulation of the above. 
         [0018]    Further, T-type calcium channel is known to be present in CNS, cardiac and vascular smooth muscle, adrenal cortex, heart, etc., and the inhibitors of the T-type calcium channel is known effective in the treatment of cerebral diseases and cardiovascular diseases such as epilepsy, hypertension, angina pectoris, etc.; {circle around (1)} Hosravani, Houman et al., “Effects of Cav3.2 channel mutations linked to idiopathic generalized epilepsy”,  Annals of Neurology  (2005), 57(5), 745-749; {circle around (2)} Vitko, Iuliia et al., “Functional characterization and neuronal modeling of the effects of childhood absence epilepsy variants of CACNA1H, a T-type calcium channel”,  Journal of Neuroscience  (2005), 25(19), 4844-4855; {circle around (3)} Moosmang, Sven et al., “Antihypertensive Effects of the Putative T-Type Calcium Channel Antagonist Mibefradil Are Mediated by the L-Type Calcium Channel Cav1.2”,  Circulation Research  (2006), 98(1), 105-110; {circle around (4)} Murielle Veniant et al., “Calcium blockade versus ACE inhibition in clipped and unclipped kidneys of 2K-1C rats”,  Kidney International , Vol 46, pp.421-429; {circle around (5)} Gillian A.

         [0019]    Recently, the antagonists of T-type calcium channel were reported to be effective in pain treatment. For example, both mibefradil and ethosuximide have shown inhibition of mechanically and thermally evoked neuronal responses in spinal nerve ligation model of neuropathic in rats.; {circle around (1)} Barton, Matthew E. et al. “The antihyperalgesic effects of the T-type calcium channel blockers ethosuximide, trimethadione, and mibefradil”,  European Journal of Pharmacology  (2005), 521(1-3), 79-85; {circle around (2)} Flatters, Sarah J.

         [0020]    USFDA approved or investigated drugs that act on the conventional inhibitors of N-type calcium channel are Gabapentin (Neurontin™) and Ziconotide (Prialt™) as antiepileptic and a neuropathic pain treatment. However, they have a rather low scope of therapeutic efficacies due to factors such as excess administration and patients&#39; characteristics, and also there is a side effect of sedating activity in case of excess dosage. 
         [0021]    Of the conventional T-type calcium channel inhibitors, Mibefradil(Ro 40-5967, WO 98/49149) had been used for the treatment of hypertension and angina pectoris. However, it is now withdrawn from market due to drug interactions leading to various adverse effects. It was shown that mibefradil inhibits cytochrome P-450 3A4 and 2D6, enzymes used to metabolize a number of therapeutic agents. Therefore, there is practically no selective T-type calcium channel inhibitor available at present, and thus it is imperative to develop an effective T-type calcium channel antagonist. 
         [0022]    Calcium channel inhibitors, due to their close association with neuronal diseases, have been actively studied by large or mid-large sized pharmaceutical firms: e.g., urea derivatives (WO 2006/024260) and heterocyclic compounds (WO 2007/137417 A1) in Neuromed Technology, Inc.; 3,4-dihydroquinazoline derivatives (Korean Pat. No. 0610731), piperazinylalkylisoxazole derivatives (Korean Pat. No. 0616099), piperazinylalkylpyrazole derivatives (Korean Pat. No. 0654328). 
         [0023]    Therefore, the inventors of the present invention have made various efforts to develop a novel compound to act in the calcium channel, and found that pyrazolylmethylamine-piperazine derivatives synthesized as a result thereof have excellent antagonistic effect against the T-type calcium channel thereby completing the present invention.

       Test Example  
       [0524]    The novel compounds of the present invention represented by the above formula 1 were tested for their antagonistic activities with regard to T-type calcium channel as follows. First, as a primary screening, of the above synthesized compounds, those which showed more than 40% of inhibition against T-type calcium channel were selected by using a HTS device FDSS6000, and their IC 50  values were determined by measuring the electric potential of Ca 2+  for the human HEK 293 cells. 
         [0525]    1) Method of Screening Activity in Relation with T-Type Calcium Channel by Using FDSS6000 
         [0526]    Twelve to twenty four hours prior to conducting an activity test, HEK293 cell line (α1G cell line: KCTC 10519BP, KRIBB (Korea Research Institute of Bioscience and Biotechnology) GENE BANK), wherein both a1G T-type calcium channel and Kir2.1 are well expressed, was subcultured into a poly-L-lysine treated 96-well plate to a concentration of 4×10 4 /well by using a 96-well cell distributor (Titertek). On the test day, the cells adhered to the 96-well plate were washed three times with HEPES buffer solution (150 mM NaCl, 5 mM KCl, 1 mM MgCl 2 , 2 mM CaCl 2 , 10 mM HEPES, 10 mM glucose, pH 7.4) by using a 96-well plate automatic washer (Bio Tek) and reacted at room temperature with HEPES buffer solution containing 5 μM fluo-3/AM and 0.001% Pluronic F-127 for 1 hour, labeled with a fluorescent dye and then washed twice with HEPES buffer solution. Then, 10 minutes prior to the test by using FDSS6000, the cells were washed once with HEPES buffer solution containing 10 mM CaCl 2 , and then the final volume was adjusted to 81 μL. Apart from the above-mentioned 96-well plate with cells, two additional 96-well plates, one containing KCl (final concentration of 75 mM) for the activation of T-type calcium channel and another containing a blocking agent of T-type calcium channel were prepared. 
         [0527]    Considering that most cell-based HTS devices only provide a liquid application system for drug injection but not a liquid absorption system, 27 μL each of the above-mentioned KCl and blocking agent was prepared respectively in HEPES buffer solution with 5 times as high as that of their respective normal concentration, diluted in the final volume of 135 μL (1/5 dilution) of the cell plate and cell activity was measured. 
         [0528]    For FDSS6000 measurements, after the 20-sec baseline recordings cells were pretreated with drugs for 75 seconds and the change in intracellular calcium concentration induced by KCl was measured. The percent inhibition by a test compound was calculated as integrated values of 340/380 fluorescent ratio of untreated and drug-treated cells. The control drug was 10 μM of Mibefradil®. 
         [0529]    In details, cells were selectively exposed to 340 nm and 380 nm light excited by xenon lamps installed in FDSS6000 using a computer-controlled filter wheel. The emitter fluorescence light through a 515 nm long-pass filter was passed by a freezing digital CCD camera mounted on the device. Data were collected every 1.23 seconds, and an average value of 340/380 fluorescent ratio for each well was obtained using a digital fluorescent analyzer. Data acquisition and analysis were performed using a program provided by Hamamatsu Photonics. 
         [0530]    2) Methods for the Measurements of T-Type Calcium Channel Activity Using an Electrophysiological Whole-Cell Patch-Clamp Technique 
         [0531]    HEK293 cells stably expressing T-type calcium channels were cultured in DMEM (Dulbecco&#39;s modified Eagle&#39;s medium) containing 10% (v/v) fetal bovine serum and 1% penicillin/streptomycin (v/v) in humidified 5% CO 2  at 36.5° C. . Cells expressing α 1G  T-type calcium channels were selected using G-418 (0.5 mg/mL) in the culture medium. The culture medium was replaced with a fresh one every 3-4 days, and cells were subcultured every week. 
         [0532]    Cells were seeded on the coverglass coated with poly-L-lysine (0.5 mg/mL) for the measurements of T-type calcium channel activity 2-7 days prior to the recordings. Whole-cell recordings of T-type calcium channel currents were performed using an EPC-9 patch clamp amplifier (HEKA, Germany). Whole-cell currents were recorded using micropipettes with resistance of 3-4MΩ with the pipette (intracellular) solution containing (in mM): 130 KCl, 11 EGTA, 5 Mg-ATP, and 10 HEPES, pH to 7.4 and with the bath (extracellular) solution containing. (in mM): 140 NaCl, 2 CaCl 2 , and 10 HEPES, pH to 7.4. The inward currents of T-type calcium channels were evoked by the test pulses of −30 mV for 50 ms at a holding potential of −100 mV every 10 seconds. 
         [0533]    Each compound was dissolved in dimethylsulfoxide (DMSO) as 10 mM stock solutions and diluted in the bath solution to 10 μM (containing 0.1% DMSO). The initial test was performed to find the range of drug concentrations that exhibits the inhibition effects, in which 1050 values were obtained (mostly in the range of 0.1-100 μM). More specifically, each compound was perfused to the bath for about 30-60 seconds, and the inhibition of the inward peak currents by a test compound was calculated as a percent inhibition from which IC 50  values were determined. The results are shown in the Table 2.
