Orally administrable compositions are generally preferred. Tablets and capsules for oral administration may be in unit dose form, and may contain conventional excipients, such as binding agents, fillers, tabletting lubricants, disintegrants and acceptable wetting agents. The tablets may be coated according to methods well known in normal pharmaceutical practice.

- the composition can be frozen after filling into the vial and the water removed under vacuum.
- Parenteral suspensions are prepared in substantially the same manner, except that the compound is suspended in the vehicle instead of being dissolved, and sterilization cannot be accomplished by filtration.
- the compound can be sterilised by exposure to ethylene oxide before suspension in a sterile vehicle.
- a surfactant or wetting agent is included in the composition to facilitate uniform distribution of the compound.
- composition may contain from 0.1% to 99% by weight, preferably from 10 to 60% by weight, of the active material, depending on the method of administration.
- the dose of the compound used in the treatment of the aforementioned disorders will vary in the usual way with the seriousness of the disorders, the weight of the sufferer, and other similar factors.
- dosage levels from 0.01 mg to 10Omg per kilogramme of body weight are useful in the treatment of pain.
- suitable unit doses may be
- 0.05 to 1000 mg more suitably 0.05 to 20, 20 to 250, or 0.1 to 500.0 mg, for example 0.2 to 5 and 0.1 to 250 mg; and such unit doses may be administered more than once a day, for example two or three a day, so that the total daily dosage is in the range of about 0.5 to 1000 mg; and such therapy may extend for a number of weeks or months.
- the two enantiomers (E3A and E3B) were separated by HPLC using Chiralpak AD column (250x19mm id), and eluting with n-hexane:ethanol (80:20 v/v) at a flow rate of 1ml/min with UV detection at 215nm.
- the compounds of the invention are vanilloid receptor (VR1) antagonists and hence have useful pharmaceutical properties.
- Vanilloid receptor (VR1) antagonist activity can be confirmed and demonstrated for any particular compound by use of conventional methods, for example those disclosed in standard reference texts such as D. Le Bars, M. Gozarin and S. W. Cadden, Pharmacological Reviews, 2001 , 53(4), 597-652] or such other texts mentioned herein.
- the screen used for the compounds of this invention was based upon a FLIPR based calcium assay, similar to that described by Smart et al. (British Journal of Pharmacology, 2000, 129, 227-230).
- Transfected astrocytoma 1321N1 cells, stably expressing human VR1 were seeded into FLIPR plates at 25,000cells/well (96-well plate) and cultured overnight.
- the cells were subsequently loaded in medium containing 4 ⁇ M Fluo-3 AM (Molecular Probes) for 2 hours, at room temperature, in the dark. The plates were then washed 4 times with Tyrode containing 1.5mM calcium, without probenecid. The cells were pre-incubated with compound or buffer control at room temperature for 30 minutes. Capsaicin (Sigma) was then added to the cells. Compounds having antagonist activity against the human VR1 were identified by detecting differences in fluorescence when measured after capsaicin addition, compared with no compound buffer controls. Thus, for example, in the buffer control capsaicin addition results in an increase in intracellular calcium concentration resulting in fluorescence.
- Fluo-3 AM Molecular Probes
- FCA 100 ⁇ l of 1 mg/ml FCA was injected intraplantar into the left paw of 4 groups of 8 male Dunkin Hartley guinea-pigs (batch: 6282434, average weight 340g). 24 hours later compounds were administered orally at 0 (vehicle), 3, 10 30mg/kg with vehicle as 1%methylcellulose and dosing volume being 2ml/kg and dosing straight into the stomach. The methylcellulose was added gradually to the compound into the pestle and mortar and ground together.
- Behavioural readouts of mechanical hyperalgesia were obtained before FCA administration (na ⁇ ve reading), after FCA but before drug administration (predose reading) and 1 hour after drug administration.
- the readout used was paw pressure (Randall-Sellito) and the end point was paw withdrawal.
- the paw pressure equipment also had one silver disc placed on the point to increase the markings by a factor of 2.
