- one of its metabolites namely the compound of formula (I) below, itself has potent 5-HT4 receptor antagonist activity.
- the present invention provides ( ⁇ )-N-[(l-butyl-4-piperidinyl)methyl]-
- the pharmaceutically acceptable salts of the compound of the formula (I) include acid addition salts with conventional acids such as hydrochloric, hydrobromic, boric, phosphoric, sulphuric acids and pharmaceutically acceptable organic acids such as acetic, tartaric. maleic, citric, succinic, benzoic. ascorbic, methanesulphonic. ⁇ -keto glutaric, ⁇ -glycerophosphoric. and glucose- 1 -phosphoric acids.
- Examples of pharmaceutically acceptable salts include quaternary derivatives of the compound of formula (I) such as the compounds quaternised by compounds R x -T wherein R x is C j.g alkyl, phenyl-C ⁇ .g alkyl or C5.7 cycloalkyl, and T is a radical corresponding to an anion of an acid.
- R x include methyl, ethyl and n- and w ⁇ -propyl; and benzyl and phenethyl.
- Suitable examples of T include halide such as chloride, bromide and iodide.
- Examples of pharmaceutically acceptable salts also include internal salts such as N-oxides.
- the compound of the formula (I) and its pharmaceutically acceptable salts, (including quaternary derivatives and N-oxides) may also form pharmaceutically acceptable solvates, such as hydrates, which are included wherever the compound of formula (I) or a salt thereof is herein referred to.
- the compound of formula (I) is a racemate.
- the present invention also covers the corresponding individual (+) and (-) enantiomers.
- the compound of formula (I) may be prepared as described in the Example below or by other conventional coupling of the indole moiety with Z, for example by reacting l-n-butyl-4-piperidinyl methylamine with (+/-)-methyl 3,4-dihydro-4-
- Aza(bi)cyclic side chain intermediates are known compounds or may be prepared according to the methods described in PCT/GB92/01519 and /01612 (SmithKline Beecham p.l.c).
- the compounds of the present invention are 5-HT4 receptor antagonists and it is thus believed may generally be used in the treatment or prophylaxis of gastrointestinal disorders, cardiovascular disorders and CNS disorders.
- EBS irritable bowel syndrome
- these compounds block the ability of 5- HT to stimulate gut motility via activation of enteric neurones. In animal models of IBS, this can be conveniently measured as a reduction of the rate of defaecation. They are also of potential use in the treatment of urinary incontinence which is often associated with IBS.
- They may also be of potential use in other gastrointestinal disorders, such as those associated with upper gut motility, and as antiemetics. In particular, they are of potential use in the treatment of the nausea and gastric symptoms of gastro- oesophageal reflux disease and dyspepsia. Antiemetic activity is determined in known animal models of cytotoxic-agent/radiation induced emesis.
- platelet-derived 5-HT induces atrial arrhythmias which encourage atrial fibrillation and atrial disorders are associated with symptomatic cerebral and sytemic embolism.
- Cerebral embolism is the most common cause of ischaemic stroke and the heart the most common source of embolic material. Of particular concern is the frequency of embolism associated with atrial fibrillation.
- Anxiolytic activity is likely to be effected via the hippocampus (Dumuis et al 1988, Mol Pharmacol., 34, 880-887). Activity may be demonstrated in standard animal models, the social interaction test and the X-maze test.
- the invention also provides a pharmaceutical composition comprising the compound of formula (I), or a pharmaceutically acceptable salt thereof, and a pharmaceutically acceptable carrier.
- compositions are prepared by admixture and are usually adapted for enteral such as oral, nasal or rectal, or parenteral administration, and as such may be in the form of tablets, capsules, oral liquid preparations, powders, granules, lozenges, reconstitutable powders, nasal sprays, suppositories, injectable and infusable solutions or suspensions. Sublingual or transdermal administration is also envisaged. Orally administrable compositions are preferred, since they are more convenient for general use.
- Tablets and capsules for oral administration are usually presented in a unit dose, and contain conventional excipients such as binding agents, fillers, diluents, tabletting agents, lubricants, disintegrants, colourants, flavourings, and wetting agents.
- the tablets may be coated according to well known methods in the art, for example with an enteric coating.
- Suitable fillers for use include cellulose, mannitol, lactose and other similar agents.
- Suitable disintegrants include starch, polyvinylpolypyrrolidone and starch derivatives such as sodium starch glycollate.
- Suitable lubricants include, for example, magnesium stearate.
- Suitable pharmaceutically acceptable wetting agents include sodium lauryl sulphate.
- Oral liquid preparations may be in the form of, for example, aqueous or oily suspensions, solutions, emulsions, syrups, or elixirs, or may be presented as a dry product for reconstitution with water or other suitable vehicle before use.
- Such liquid preparations may contain conventional additives such as suspending agents, for example sorbitol, syrup, methyl cellulose, gelatin, hydroxyethylcellulose, carboxymethylcellulose, aluminium stearate gel or hydrogenated edible fats, emulsifying agents, for example lecithin, sorbitan monooleate, or acacia; non-aqueous vehicles (which may include edible oils), for example, almond oil, fractionated coconut oil, oily esters such as esters of glycerine, propylene glycol, or ethyl alcohol; preservatives, for example methyl or propyl p-hydroxybenzoate or sorbic acid, and if desired conventional flavourin ⁇ g or colouring agents.
