COMBINATION OF A NMDA-RECEPTOR LIGAND AND A COMPOUND WITH 5-HT6 RECEPTOR AFFINITY
FIELD OF THE INVENTION The present invention relates to an active substance combination comprising at least one compound with 5-HT6 receptor affinity, and at least one N-methyl-D-aspartate -receptor ligand (NMDA-receptor ligand), a medicament comprising said active substance combination, and the use of said active substance combination for the manufacture of a medicament.
BACKGROUND
Cognitive and/or degenerative brain disorders are characterized clinically by progressive loss of memory, cognition, reasoning, judgement and emotional stability that gradually leads to profound mental deterioration and ultimately death. In an example of such disorders, Alzheimer's disease is a common cause of progressive mental failure (dementia) in aged humans and is believed to represent the fourth most common medical cause of death in the United States. In particular, Alzheimer's disease is associated with degeneration of cholinergic neurons in the basal forebrain that play a fundamental role in cognitive functions, including memory. Cognitive and/or degenerative brain disorders have been observed in varied races and ethnic groups world- wide and present a major public health problem. These diseases are currently estimated to affect about two to three million individuals in the United States alone and the occurrence will increase world- wide as the human life span increases.
Cognitive and/or degenerative brain disorders are incurable with presently used medications, however, the symptoms of these disorders seem to be possibly alleviated by using compounds such as memantine.
Whereas known compounds which act as NMDA-receptor ligands are generally effective for treating disorders related to NMDA-receptors such as cognitive disorders, in particular for treating Alzheimer's disease, in some instances they show undesirable side effects. Specifically, many of these compounds that have been tested in humans can cause potentially serious side effects such as gastrointestinal complications including
insomnia, restlessness, headache, akathisia, fatigue, nausea, emesis, ulcers, constipation, flatulence, diarrhea, hypertension, respiratory depression and psychological and physical dependence.
Therefore, there is a need to provide a medicament suitable for the prophylaxis and/or treatment of disorders related to NMDA-receptors and to 5-HT6 receptors, which preferably does not show the undesired side effects of the conventional compounds which act as NMDA-receptor ligands, or at least less frequent and/or less pronounced.
BRIEF DESCRIPTION OF THE INVENTION
The authors of the present invention have developed a medicament suitable for the prophylaxis and/or treatment of cognitive disorders, in particular for treating Alzheimer's disease, which does not show, or at least reduced significantively, the undesired side effects mentioned above of the conventional medicaments.
Therefore, a first aspect of the present invention relates to an active substance combination comprising:
(A) at least one compound with 5-HT6 receptor affinity,
and
(B) at least one NMDA-receptor ligand.
It has surprisingly been found that the compounds with 5-HT6 receptor affinity and the compounds which act as NMDA-receptor ligands show a synergistic effect in their pharmacological activities. Consequently, the dose of the corresponding compounds may be reduced in comparison to the dose necessary for an individual administration of said compounds.
According to the invention it has also been found that the action of a NMDA-receptor antagonist potentiates the action of the compound with 5-HT6 receptor affinity, so the combination of a NMDA-receptor antagonist and a compound with 5-HT6 receptor
affinity for use in the treatment of disorders that are related to NMD A-recep tors, and to 5-HT6 receptors may result in a faster onset of action and an increased success rate. The invention therefore particularly resides in the combined action of a NMDA-receptor compound, particularly an antagonist, and a compound with 5-HT6 receptor affinity, or the dual action of a substance possessing both NMDA-receptor antagonist activity and 5-HT6 receptor affinity, for the treatment of disorders that are related to NMDA- receptors, and/or to 5-HT6 receptors.
In another aspect, the present invention relates to a medicament comprising the active substance combination as defined above and optionally one or more pharmacologically acceptable adjuvants.
A third aspect of the invention refers to a medicament as defined above, for simultaneous NMDA-receptor inhibition and 5-HT6-receptor regulation.
Also, another aspect of the invention relates to the use of the active substance combination in the manufacture of a medicament for simultaneous NMDA-receptor inhibition and 5-HT6-receptor regulation.
Another aspect of the invention refers to a pharmaceutical formulation which comprises the active substance combination and optionally one or more pharmacologically acceptable adjuvants.
Finally, the present invention also relates to a method for simultaneous NMDA-receptor inhibition and 5-HT6-receptor regulation, said method comprises administering to a patient in need of such a treatment a therapeutically effective amount of an active substance combination as defined above.
BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 shows the results obtained for the novel object discrimination paradigm trial in rats, when they have been administered intraperitoneally with different doses of memantine (0, 5,10, 15 and 20 mg/kg).
Figure 2 shows the results obtained for the novel object discrimination paradigm trial in rats, when they have been administered intraperitoneally with the compound 841 alone, with memantine alone, or with a combination of compound 841 and memantine.
DETAILED DESCRIPTION OF THE INVENTION
In the treatment of cognitive disorders, the effect on e.g. memory or novel object discrimination is significantly greater in the group that is treated with a combination of at least one NMDA-receptor antagonist and at least one compound with 5-HT6 receptor affinity than in the group that is treated with at least one NMDA-receptor antagonist or at least one compound with 5-HT6 receptor affinity exclusively.
Also there is an indication that in the treatment of depression, the effect on the symptoms - in an animal model - is more pronounced in the group that is treated with a combination of at least one NMDA-receptor antagonist and at least one compound with 5-HT6 receptor affinity than in the group that is treated with at least one NMDA- receptor antagonist or at least one compound with 5-HT6 receptor affinity exclusively.
In one embodiment of the present invention the binding of compounds present as component (A) to the 5-HT6-receptor is determined by a K1 value of less than 7000 nM, particularly preferably of less than 6500 nM, more particularly preferably of less than 200 nM, more particularly preferably of less than 100 nM.
In one embodiment of the present invention, the compounds present as component (B) act as NMDA-receptor antagonists. The NMDA-receptor antagonist of the invention may be any ligand that binds to and inhibits the NMDA-receptor, thereby resulting in a biological response. The potential of a given substance to act as a NMDA-receptor antagonist may be determined using standard in vitro binding assays and/or standard in vivo functionality tests.
In one embodiment of the present invention the binding of compounds present as component (B) to the NMDA-receptor is determined by an EC50 or IC50 value of less than 300 μM, preferably less than 100 μM, when determined in a standard functionality assay using a mouse, rat, or human NMDA-receptor ion channel.
In one embodiment the NMDA-receptor antagonist blocks the NMDA receptor at the PCP binding site
In another embodiment of the present invention as component (A) at least one compound is present, which is selected from the group consisting of the benzoxazinone- derived sulfonamide compounds of general formula (Ia)

The NMDA receptor is a cell-surface protein complex, widely distributed in the mammalian central nervous system that belongs to the class of ionotropic-glutamate
receptors. It is involved in excitatory- synaptic transmission and the regulation of neuronal growth. The structure comprises a ligand-gated/voltage- sensitive ion channel. The NMDA receptor is highly complex and is believed to contain at least five distinct binding (activation) sites: a glycine-binding site, a glutamate-binding site (NMDA- binding site); a PCP-binding site, a polyamine-binding site, and a zinc-binding site. In general, a receptor antagonist is a molecule that blocks or reduces the ability of an agonist to activate the receptor. As used herein, an "NMDA-receptor antagonist" means any compound or composition, known or to be discovered, that when contacted with an NMDA receptor in vivo or in vitro, inhibits the flow of ions through the NMDA- receptor ion channel.
According to the present invention the meaning of the phrase "NMDA-receptor antagonist" encompasses any compound or composition that antagonizes the NMDA receptor by binding at the glycine site. Glycine-site NMDA-receptor antagonists can be identified by standard in vitro and in vivo assays. See, for example, the assays described in U.S. Pat. No. 6,251,903 (issued Jun. 26, 2001); U.S. Pat. No. 6,191,165 (issued Feb. 20, 2001); Grimwood et al. MOLECULAR PHARMACOLOGY 923 (1992); Yoneda et al. J. NEUROCHEM. 102 (1994); and Mayer et al. J. NEUROPHYSIOL. 645 (1988).

The term "cognitive disorder" indicates disruptions in performance including one or more of the following signs:
1) memory deficits (impaired ability to learn new information or recall previously learned information;
2) one (or more) of the following disturbances: a) aphasia (language disturbance) b) apraxia (impaired ability to carry out motor activities despite intact motor function) c) agnosia (failure to recognize or identify objects despite in tact sensory function) d) disturbance in executive functioning (i.e. planning, organizing, sequencing, abstracting);
3) memory disturbances causing significant impairment in social or occupational functioning, and representing a significant decline from a previous level of functioning; and
4) impairment in cognitive functioning as evidenced by neuropsychological testing or quantified clinical assessment, accompanied by objective evidence of a systemic general medical condition or central nervous system dysfunction.
Cognitive disorders (or memory disorders) may include Alzheimer's disease, senile dementia process, learning disabilities caused by degenerative disorders, learning disabilities caused by non-degenerative disorders, memory or cognitive dysfunction such as mild cognitive impairment, age-related cognitive decline, cerebral senility, vascular dementia, AIDS-associated dementia, electric shock induced amnesia, memory impairment associated with depression or anxiety, cognitive defects in Parkinson's disease, Down's syndrome, stroke, traumatic brain injury, Huntington's disease, and attention deficit disorder; especially ADHD (attention deficit / hyperactivity disorder).
"Treatment" (e.g. of cognitive disorders, e.g. depression or e.g. of obesity and obesity- related disorders) refers to the administration of the compounds or combinations of the present invention to treat (in the case of cognitive disorders or dpression) the disorder or - more often - the symptoms of these disorders; or (for obesity) reduce or maintain the body weight of an obese subject. One outcome of treatment may be ameliorating the symptoms of e.g. Alzheimer's disease or the clinical depression or may be reducing the body weight of an obese subject relative to that subject's body weight immediately before the administration of the compounds or combinations of the present invention. A preferred aspect of the treatment, especially for cognitive disorders or depression, also
involves the prophylaxis against the disorder, thus preventing the occurrence of its symptoms. Another outcome of treatment may be preventing body weight regain of body weight previously lost as a result of diet, exercise, or pharmacotherapy.
Another outcome of treatment may be decreasing the occurrence of and/or the severity of obesity-related diseases. Another outcome of treatment may be to maintain weight loss. The treatment may suitably result in a reduction in food or calorie intake by the subject, including a reduction in total food intake, or a reduction of intake of specific components of the diet such as carbohydrates or fats; and/or the inhibition of nutrient absorption; and/or the inhibition of the reduction of metabolic rate; and in weight reduction in patients in need thereof. The treatment may also result in an alteration of metabolic rate, such as an increase in metabolic rate, rather than or in addition to an inhibition of the reduction of metabolic rate; and/or in minimization of the metabolic resistance that normally results from weight loss.
The term "depression" or especially "clinical depression" is referring to a state of sadness, melancholia or despair that has advanced to the point of being disruptive to an individual's social functioning and/or activities of daily living.
"Obesity" is a condition in which there is an excess of body fat. The operational definition of obesity is based on the Body Mass Index(BMI), which is calculated as body weight per height in meters squared (kg/m ). "Obesity" refers to a condition whereby an otherwise healthy subject has a Body Mass Index (BMI) greater than or equal to 30kg/m2, or a condition whereby a subject with at least one co-morbidity has a BMI greater than or equal to 27kg/m2. An "obese subject" is an otherwise healthy subject with a Body Mass Index (BMI) greater than or equal to 30 kg/m2 or a subject with at least one co-morbidity with a BMI greater than or equal to 27 kg/m2. A "subject at risk of obesity" is an otherwise healthy subject with a BMI of 25 kg/m to less than 30 kg/m2 or a subject with at least one co-morbidity with a BMI of 25 kg/m2 to less than 27 kg/m2.
The increased risks associated with obesity occur at a lower Body Mass Index(BMI) in Asians. In Asian countries, including Japan, "obesity" refers to a condition whereby a
subject with at least one obesity-induced or obesity-related co-morbidity, that requires weight reduction or that would be improved by weight reduction, has a BMI greater than or equal to 25 kg/m2. In Asian countries, including Japan, an "obese subject" refers to a subject with at least one obesity-induced or obesity -related co-morbidity that requires weight reduction or that would be improved by weight reduction, with a BMI greater than or equal to 25kg/m . In Asia-Pacific, a "subject at risk of obesity" is a subject with a BMI of greater than 23 kg/m to less than 25 kg/m .
As used herein, the term "obesity" is meant to encompass all of the above definitions of obesity.
Obesity-induced or obesity-related co-morbidities include, but are not limited to, diabetes, non-insulin dependent diabetes mellitus-type II (2), impaired glucose tolerance, impaired fasting glucose, insulin resistance syndrome, dyslipidemia, hypertension, hyperuricacidemia, gout, coronary artery disease, myocardial infarction, angina pectoris, sleep apnea syndrome, Pickwickian syndrome, fatty liver; cerebral infarction, cerebral thrombosis, transient ischemic attack, orthopedic disorders, arthritis deformans, lumbodynia, emmeniopathy, and infertility.
In particular, co-morbidities include: hypertension, hyperlipidemia, dyslipidemia, glucose intolerance, cardiovascular disease, sleep apnea, diabetes mellitus, and other obesity-related conditions.
The term "Metabolic syndrome", also known as syndrome X, is defined in the Third Report of the National Cholesterol Education Program Expert Panel on Detection,
Evaluation and Treatment of High Blood Cholesterol in Adults (ATP-E). E. S. Ford et al. , JAMA, Vol. 287 (3), Jan. 16, 2002, pp 356-359. Briefly, a person is defined as having Metabolic syndrome if the person has three or more of the following symptoms: abdominal obesity, hypertriglyceridemia, low HDL cholesterol, high blood pressure, and high fasting plasma glucose.
The terms "administration of" and or "administering a" compound should be understood to mean providing a compound of the invention or a prodrug of a compound of the invention to a subject in need of treatment.
The instant pharmaceutical composition includes administration of a single pharmaceutical dosage formulation which contains both the compound with 5-HT6 receptor affinity, and at least one NMDA-receptor ligand, as well as administration of each active agent in its own separate pharmaceutical dosage formulation. Where separate dosage formulations are used, the individual components of the composition can be administered at essentially the same time, i. e., concurrently, or at separately staggered times, i. e. sequentially prior to or subsequent to the administration of the other component of the composition. The instant pharmaceutical composition is therefore to be understood to include all such regimes of simultaneous or alternating treatment, and the terms "administration" and "administering" are to be interpreted accordingly.
Administration in these various ways are suitable for the present compositions as long as the beneficial pharmaceutical effect of the combination of the compound with 5-HT6 receptor affinity, and at least one NMDA-receptor ligand, is realised by the patient at substantially the same time.
Such beneficial effect is preferably achieved when the target blood level concentrations of each active drug are maintained at substantially the same time. It is preferred that the combination of the compound with 5-HT6 receptor affinity, and at least one NMDA- receptor ligand, be co-administered concurrently on a once-a-day dosing schedule; however, varying dosing schedules, such as the compound with 5-HT6 receptor affinity once a day and the NMDA-receptor ligand once, twice or more times per day, is also encompassed herein. A single oral dosage formulation comprised of both a compound with 5-HTό receptor affinity and a NMDA-receptor ligand is preferred. A single dosage formulation will provide convenience for the patient, which is an important consideration especially for patients with diabetes or obese patients who may be in need of multiple medications.
The term "subject" as used herein refers to an animal, preferably a mammal, most preferably a human, who has been the object of treatment, observation or experiment.
The administration of the composition of the present invention in order to practice the present methods of therapy is carried out by administering a therapeutically effective amount of the compounds in the composition to a subject in need of such treatment or prophylaxis. The need for a prophylactic administration according to the methods of the present invention is determined via the use of well known risk factors. The effective amount of an individual compound is determined, in the final analysis, by the physician in charge of the case, but depends on factors such as the exact disease to be treated, the severity of the disease and other diseases or conditions from which the patient suffers, the chosen route of administration, other drugs and treatments which the patient may concomitantly require, and other factors in the physician's judgement.
The term "therapeutically effective amount" as used herein means the amount of the active compounds in the composition that will elicit the biological or medical response in a tissue, system, subject, or human that is being sought by the researcher, veterinarian, medical doctor or other clinician, which includes alleviation of the symptoms of the disorder being treated. The novel methods of treatment of this invention are for disorders known to those skilled in the art.
The term "salt" as used herein is to be understood as meaning any form of the compounds in which they assume an ionic form or are charged and are coupled with a counter-ion (a cation or anion) or are in solution. By this are also to be understood complexes of the active compound with other molecules and ions, in particular complexes which are complexed via ionic interactions.
The term "physiologically acceptable salt" is understood in particular, in the context of this invention, as salt (as defined above) formed either with a physiologically tolerated acid, that is to say salts of the particular active compound with inorganic or organic acids which are physiologically tolerated - especially if used on humans and/or mammals - or with at least one, preferably inorganic, cation which are physiologically tolerated - especially if used on humans and/or mammals. Examples of physiologically
tolerated salts of particular acids are salts of: hydrochloric acid, hydrobromic acid, sulfuric acid, hydrobromide, monohydrobromide, monohydrochloride or hydrochloride, methiodide, methanesulfonic acid, formic acid, acetic acid, oxalic acid, succinic acid, malic acid, tartaric acid, mandelic acid, fumaric acid, lactic acid, citric acid, glutamic acid, hippuric acid, picric acid and/or aspartic acid. Examples of physiologically tolerated salts of particular bases are salts of alkali metals and alkaline earth metals and with NH4.
Solvates, preferably hydrates, of the compounds of the present invention and in each case of corresponding stereoisomers may also be obtained by standard procedures known to those skilled in the art.
The term "solvate" according to this invention is to be understood as meaning any form of the compounds in which they have attached to it via non-covalent binding another molecule (most likely a polar solvent) especially including hydrates and alcoholates, e.g. methanolate.
The active substance combination according to this invention comprises preferably 1- 99% by weight of the component (A) and 99-1% by weight of the component (B), more preferably 10-80% by weight of the component (A) and 80-20% by weight of the component (B), these percentages referring to the total weight of both components (A) and (B).

The water-insoluble polymers used to produce a sustained-release material are preferably based on an acrylic resin, which is preferably selected from the group of poly(meth)acrylates, particularly preferably poly(Ci_4)alkyl (meth)acrylates, poly(Ci-4)dialkylamino(Ci_4)alkyl (meth)acrylates and/or copolymers or mixtures thereof, and very particularly preferably copolymers of ethyl acrylate and methyl methacrylate with a monomer molar ratio of 2:1 (Eudragit NE30D®), copolymers of ethyl acrylate, methyl methacrylate and trimethylammonium ethyl methacrylate - chloride with a monomer molar ratio of 1:2:0.1 (Eudragit RS ®), copolymers of ethyl acrylate, methyl methacrylate and trimethylammonium ethyl methacrylate-chloride with a monomer molar ratio of 1:2:0.2 (Eudragit RL®), or a mixture of at least two of the above-mentioned copolymers. These coating materials are commercially available as 30 wt.% aqueous latex dispersions, i.e. as Eudragit RS30D®, Eudragit NE30D® or Eudragit RL30D®, and may also be used as such for coating purposes.
In another embodiment, the sustained-release material is based on water-insoluble cellulose derivatives, preferably alkyl celluloses, particularly preferably ethyl cellulose, or cellulose esters, e.g. cellulose acetate. Aqueous ethyl cellulose dispersions are commercially available, for example, under the trademarks Aquacoat® or Surelease®.
As natural, semisynthetic or synthetic waxes, fats or fatty alcohols, the sustained-release material may be based on carnauba wax, beeswax, glycerol monostearate, glycerol monobehenate, glycerol ditripalmitostearate, microcrystalline wax, cetyl alcohol, cetylstearyl alcohol or a mixture of at least two of these components.
The afored mentioned polymers of the sustained-release material may also comprise a conventional, physiologically acceptable plasticizer in amounts known to those skilled in the art.
Examples of suitable plasticizers are lipophilic diesters of a CO-C4O aliphatic or aromatic dicarboxylic acid and a Ci-Cs aliphatic alcohol, e.g. dibutyl phthalate, diethyl phthalate, dibutyl sebacate or diethyl sebacate, hydrophilic or lipophilic citric acid esters, e.g. triethyl citrate, tributyl citrate, acetyltributyl citrate or acetyltriethyl citrate, polyethylene glycols, propylene glycol, glycerol esters, e.g. triacetin, Myvacet® (acetylated mono- and diglycerides, C23H44C"5 to C2SH47O7), medium-chain triglycerides (Miglyol®), oleic acid or mixtures of at least two of said plasticizers.
Aqueous dispersions of Eudragit RS® and optionally Eudragit RL® preferably contain triethyl citrate. The sustained-release material may comprise one or more plasticisers in amounts of, for example, 5 to 50 wt.% based on the amount of polymer(s) used.
The sustained-release material may also contain other conventional auxiliary substances known to those skilled in the art, e.g. lubricants, coloured pigments or surfactants.
The pharmaceutical formulation of the present invention may also comprise at least one of the components (A) and (B) covered by an enteric coating form which dissolves as a function of pH. Because of this coating, part or all of the pharmaceutical formulation can pass through the stomach undissolved and the components (A) and/or (B) are only released in the intestinal tract. The enteric coating preferably dissolves at a pH of between 5 and 7.5.
The enteric coating may be based on any enteric material known to those skilled in the art, e.g. on methacrylic acid/methyl methacrylate copolymers with a monomer molar ratio of 1:1 (Eudragit L®), methacrylic acid/methyl methacrylate copolymers with a monomer molar ratio of 1:2 (Eudragit S®), methacrylic acid/ethyl acrylate copolymers with a monomer molar ratio of 1:1 (Eudragit L30D-55®), methacrylic acid/methyl acrylate/methyl methacrylate copolymers with a monomer molar ratio of 7:3:1 (Eudragit FS ®), shellac, hydroxypropyl methyl cellulose acetate-succinates, cellulose acetate-phthalates or a mixture of at least two of these components, which can optionally also be used in combination with the above-mentioned water-insoluble
poly(meth)acrylates, preferably in combination with Eudragit NE30D® and/or Eudragit RL® and/or Eudragit RS®.
The coatings of the pharmaceutical formulations of the present invention may be applied by the conventional processes known to those skilled in the art, e.g. from Johnson, J. L., "Pharmaceutical tablet coating", Coatings Technology Handbook (Second Edition), Satas, D. and Tracton, A. A. (Eds), Marcel Dekker, Inc.

Mathiowitz, E. (Ed.), John Wiley & Sons, Inc., New York (1999), Vol. 1, 299-311. The respective descriptions are incorporated by reference and are part of the disclosure.
In another embodiment, the pharmaceutical formulation of the present invention contains one or both of components (A) and (B) not only in sustained-release form, but also in non-sustained-release form. By combination with the immediately released form, a high initial dose can be achieved for the rapid onset of the beneficial effect. The slow release from the sustained-release form then prevents the beneficial effect from diminishing. Such a pharmaceutical formulation is particularly useful for the treatment of acute health problems.
This may be achieved, for example, by a pharmaceutical formulation having at least one immediate-release coating comprising at least one of the components (A) and (B) to provide for rapid onset of the beneficial effect after administration to the patient.
The present invention also relates to the treatment the aforementioned disorders and/or diseases with a combination of at least one compound with 5-HT6 receptor affinity and at least one NMDA-receptor ligand which may be administered separately, therefore the invention also relates to combining separate pharmaceutical compositions into a kit form. The kit, according to this invention, comprises two separate pharmaceutical compositions: a first unit dosage form comprising a prophylactically or therapeutically
effective amount of at least one NMDA-receptor ligand, or a pharmaceutically acceptable salt or ester thereof, and a pharmaceutically acceptable carrier or diluent in a first unit dosage form, and a second unit dosage form comprising a prophylactically or therapeutically effective amount of at least one compound with 5-HT6 receptor affinity, or a pharmaceutically acceptable salt or ester thereof, and a pharmaceutically acceptable carrier or diluent in a second unit dosage form. The kit further comprises a container. Such kits are especially suited for the delivery of solid oral forms such as tablets or capsules. Such a kit preferably includes a number of unit dosages. Such kits can include a card having the dosages oriented in the order of their intended use. An example of such a kit is a "blister pack". Blister packs are well known in the packaging industry and are widely used for packaging pharmaceutical unit dosage forms. If desired, a memory aid can be provided, for example in the form of numbers, letters, or other markings or with a calendar insert, designating the days or time in the treatment schedule in which the dosages can be administered.
Example
Example 1. Test of novel object discrimination in rats
Adult male Lister Hooded rats (Charles River, UK) weighing 200-35Og at the start of the experiment were housed in groups of four on a 12:12 h light:dark cycle (lights on at 07:00 h). Food and water were available ad libitum throughout the study, and the room temperature (21 ± 2°C) and relative humidity (45-65%) were kept constant. In one experiment, rats received i.p. injections (2ml/kg, -20 minutes prior to the familiarisation trial) of memantine (n=12) at 5, 10, 15 and 20mg/kg compared with vehicle (0.5% methylcellulose in saline, 2ml/kg), such that all rats received all doses of the compound in a random order with each behavioural test occurring at seven day intervals.
In the combination study, a group of rats (n=12 each) received injection of a sub- effective dose of compound 841 (lmg/kg i.p.) or vehicle (0.5% methylcellulose in saline, 2ml/kg), either alone or combined with memantine (5mg/kg). Each drug combination was administered to all rats in the group over a period of 4 weeks in a random order using a seven day behavioural test interval.
The two trial novel object discrimination paradigm utilised, was as described by Ennanceur and Delacour, (A new one-trial test for neurobiological studies of memory in rats. 1: Behavioral data. Behav Brain Res 31, 47-59, 1988) with minor modification
(King et al., "5-ht6 receptor antagonists reverse delay-dependent deficits in novel object discrimination by enhancing consolidation-an effect sensitive to NMDA receptor antagonism", Neuropharmacol. 41, 195-204, 2004; Woolley et al., "Reversal of a cholinergic-induced deficit in a rodent model of recognition memory by the selective 5- ht6 receptor antagonist, Ro 04-6790", Psychopharmacol. 170, 358-367, 2003). The twelve open field test arenas used for object discrimination were clear perspex boxes (39 x 23.5 cm with 24.5 cm high walls) to which each rat was habituated for 60 minutes the day prior to test days. On the test day, for the first experiment, the administration was 20 minutes before acclimatisation. For the combination experiment, the first drug was administered -40 minutes and the second drug -20 minutes before the familiarisation trial. Therefore, 20 minutes after the injection each rat received 3 minutes acclimatisation to the perspex box in absence of objects which was then followed by the 3 minute familiarisation trial and a second 3 minute choice trial following a 4 hour inter-trial interval. During both trials, exploration of each object was defined as the time spent (s) sniffing (within 1 cm of it with active vibrissae), licking, chewing or touching the object with the nose.
The results obtained for the first trial were shown in Figure 1. As can be seen, when memantine is administered alone, high amounts of said compound are necessary for rats to discriminate a novel object against a familiar object. On the contrary, as showm in Figure 2 for the second trial, the combined administration of memantine and compound 841 in lower doses (5 and 1 mg/kg, respectively) makes the animal to spend more time exploring the novel/unknown object than when the object is familiar for him, thus proving a better ability to memorize or distinguish a novel from a known object.
