The present invention relates, in general, to racemic or enantiomerically enriched novel 3-substituted propanamine derivatives and pharmaceutically useful salts thereof, a pharmaceutical composition comprising an effective amount of racemic or enantiomerically enriched novel 3-substituted propanamine derivatives as monoamine neurotransmitter re-uptake inhibitors to treat central nervous system diseases and a method of treating central nervous system diseases in a mammal. More particularly, the present invention relates to racemic or enantiomerically enriched novel 3-substituted propanamine derivatives having various azole moieties and pharmaceutically useful salts thereof, useful to treat the diseases of the central nervous system such as depression, anxiety and pain disorder.
The three biogenic amines, serotonin, norepinephrein and dopamine are most closely linked to CNS disorders such as depression. The majority of antidepressants in current use selectively inhibit the reuptake of serotonin and/or norepinephrine. Although a strong dopamine re-uptake inhibiting activity is considered with the risk of undesirable central stimulation effects, many reports have disclosed that the triple monoamine neurotransmitter, i.e serotonin, norepinephrine and dopamine, re-uptake inhibitors are useful for the treatment of CNS disorders such as depression, anxiety, attention deficit hyperactivity disorder, obesity, drug addiction and pain disorder. For example, International Patent Application No. WO 2004/072071 discloses the novel 8-aza-bicyclo[3,2,1]octane derivatives useful as monoamine neurotransmitter re-uptake inhibitors.
3-substituted propanamine compounds are effectively used for controlling various central nervous system (CNS) disorders. For example, International Patent Application No. WO 04/43931 discloses 3-substituted propanamine derivatives that are suitable for treating anxiety, depression, sleep disorder. Similarly heteroaryloxy 3-substituted propanamine is disclosed in U.S. Pat. Nos. 7,037,932 and 3-Amino-1-arylpropyl indole derivatives are disclosed in International Patent Application No. WO 05/118539 as monoamine reuptake inhibitor for the treatment of various central nervous system disorders. Active research and development efforts have continued to be directed to the application of 3-substituted propanamine compounds for the treatment of CNS disorders.

The therapeutic uses of the racemic or enantiomerically enriched compounds and their pharmaceutically useful salts according to present invention have been established by the following tests.
Serotonin Transporter Reuptake Inhibition Assay
The method to test the ability of compounds to inhibit transporters from reuptake of serotonin followed Gu H. et al., J Biol. Chem., 1994, 269, p 7214˜7130.
The recombinant HEK-293 cells with human serotonin transporter were plated. Test compounds described in table 1 were pre-incubated with cells (2×105/ml) in modified Tris-HEPES buffer pH 7.1 for 20 minutes at 25° C. and then they were incubated for additional 10 minutes after 65 nM of [3H]Serotonin was added. Bound cells were filtered and counted to determine [3H]Serotonin uptake. Reduction of [3H]Serotonin uptake by 50 percent or more (≧50%) relative to 10 μM fluoxetine indicates significant inhibitory activity. Compounds were screened at 10, 1, 0.1, 0.01 and 0.001 μM for IC50s.
Norepinephrine Transporter Reuptake Inhibition Assay
Norepinephrine transporter reuptake inhibition assay used the method described by Galli A. et al., J Exp Biol., 1995, 198, p 2197˜2212.
MDCK cells with stably expressed human recombinant norepinephrine transporter were plated one day. Test compounds were pre-incubated with cells (2×105/ml) in modified Tris-HEPES buffer pH 7.1 for 20 minutes at 25° C. and then they were incubated for additional 10 minutes after 25 nM of [3H]Norepinephrine was added. A lysate was obtained from solubilized cells and the filtered lysate was counted to determine [3H]Norepinephrine uptake. Reduction of [3H]Norepinephrine uptake by 50 percent or more (≧50%) relative to 10 μM desipramine indicates significant inhibitory activity. Compounds were screened at 10, 1, 0.1, 0.01 and 0.001 μM to determine their IC50s.
Dopamine Transporter Reuptake Inhibition Assay
The assay followed the method modified from Pristupa Z. B. et al., Mol. Pharmacol., 1994, p 125˜135.
CHO-K1 cells with human recombinant dopamine transporter were plated. Test compounds were pre-incubated with cells (4×105/ml) in modified Tris-HEPES buffer pH 7.1 for 20 minutes at 25° C. and then they were incubated for additional 10 minutes after 50 nM of [3H]Dopamine was added. A lysate is obtained from solubilized cells and counted to determine [3H]Dopamine uptake. Reduction of [3H]Dopamine uptake by 50 percent or more (≧50%) relative to 10 μM nomifensine indicates significant inhibitory activity. Compounds were tested at 10, 1, 0.1, 0.01 and 0.001 μM for IC50s.
The results obtained by testing compounds of the invention are given in the following table 1:
The data in Table 1 show that racemic or enantiomerically enriched 3-substituted propanamine derivatives, the compounds of the invention have a significantly high inhibition potency of the serotonin, norepinephrine, dopamine transporter reuptake. This inhibition of serotonin, norepinephrine, dopamine transporter reuptake has been associated with the treatment of one or more of the CNS disorders such as depression, anxiety and pain disorder.
Forced Swimming Test in Mice (FST)
The Forced swimming test is an animal model based on the rodent's behavioral repertoire for screening drugs with potential antidepressant activity. As in several other models used for this goal, an uncontrollable stress stimulus produces behavioral changes that are sensitive to antidepressant treatment.
The mice were intraperitoneally treated with the test compound with an injection volume of 10 mg/kg. The group treated with 30% PEG400 served as a control group. Thirty minutes following administration, mice were individually forced to swim in a transparent glass vessel (14 cm high, 11.5 cm in diameter) filled with 10 cm of water at 25° C. The total duration of immobility (second) was measured during the last 4 minutes of a single 6-min test session. Mice were considered immobile when they made no further attempts to escape other than the movements necessary to keep their heads above the water. The potent ability of the compounds was determined as percent value of reduction in the duration of immobility comparing to the control group.
The results obtained by testing compounds of the invention are given in the following table 2:
Specially the results of forced swimming test (FST) in mice as noted in Table 2 show the compounds of the invention are related to the treatment of depression.
Marble Burying Test
The Marble burying test is a screening tool for putative anxiolytics. In this test, control mice naturally bury glass marbles in the cage bedding and the administration of anxiolytic compounds, including Diazepam, reduces the number of buried marbles. Positive compounds in the marble burying test including selective serotonin reuptake inhibitor may be especially beneficial to obsessive-compulsive disorder.
A group of mice was intraperitoneally treated with test compound dissolved in 30% PEG400 with an injection volume of 10 ml/kg. The group treated with only 30% PEG400 served as a control group. Thirty minutes after the treatment, the animals were individually placed in a polycarbonate cage which was same as used for animal housing with an open top located within a quiet room. Each cage consisted of ⅛ inch corn bedding 5 cm deep. Twenty four clean glass marbles (15 mm diameter) were evenly spaced in four rows of six on top of the bedding. Each mouse was left in the cage for 30 minutes and the number of marbles buried (buried more than ½ or ⅔) was counted. The potent ability of the compounds was determined as percent value of reduction in the number of marbles buried comparing to the control group.
The results obtained by testing compounds of the invention are given in the following table 3:
Specially the results of Marble burying test (MB) in mice as noted in Table 3 show the compounds of the invention are related to the treatment of anxiety.
Acetic Acid Induced Writhing Test (AA Writhing Test)
The Acetic acid-induced writhing test is a well-established nociceptive test using a chemical stimulus. Although several animal models of nociceptive tests have been developed to examine and compare the anti-nociceptive effects of different drugs, the anti-nociceptive effects of antidepressants appear to be test-dependent. Indeed, the acetic acid-induced writhing test is more sensitive to antidepressants than other tests using thermal, mechanical or electrical stimuli.
The animals were subcutaneously treated with the test compound with an injection volume of 10 ml/kg. The group treated with 30% PEG400 or saline served as a control group. Thirty minutes later, the mice were intraperitoneally treated with 0.8% (v/v) acetic acid. Each mouse was then placed in a cage for individual observation. The writhing numbers for 10 minutes were counted. The writhe is operationally defined as a contraction of the abdomen followed by stretching of the hind limbs. The potent ability of the compounds was determined as percent value of reduction in the number of writhing comparing to the control group.
The results obtained by testing compounds of the invention are given in the following table 4:
Specially the results of Acetic acid induced writhing test (AA writhing test) in mice as noted in Table 4 show the compounds of the invention are related to the treatment of pain.
