Definitions

  • the present invention relates to substituted alkyl esters of polycyclic amino alcohols, a process for their preparation, pharmaceutical compositions containing them, a process for preparing pharmaceutical compositions, their use in therapy and intermediates of use in their preparation.
  • Muscarinic receptors are a G-protein coupled receptor (GPCR) family having five family members M 1 , M 2 , M 3 , M 4 and M5. Of the five muscarinic subtypes, three (M 1 , M 2 and M 3 ) are known to exert physiological effects on human lung tissue.
  • GPCR G-protein coupled receptor
  • Parasympathetic nerves are the main pathway for reflex bronchoconstriction in human airways and mediate airway tone by releasing acetylcholine onto muscarinic receptors.
  • Airway tone is increased in patients with respiratory disorders such as asthma and chronic obstructive pulmonary disease (COPD), and for this reason muscarinic receptor antagonists have been developed for use in treating airway diseases.
  • Muscarinic receptor antagonists often called anticholinergics in clinical practice, have gained widespread acceptance as a first-line therapy for individuals with COPD, and their use has been extensivley reviewed in the literature (e.g. Lee et al, Current Opinion in Pharmacology 2001,1, 223-229).
  • muscarinic receptor antagonists When used to treat respiratory disorders, muscarinic receptor antagonists are typically administered by inhalation. However, when administered by inhalation a significant proportion of the muscarinic receptor antagonist is often absorbed into the systemic circulation resulting in reported side effects such as dry mouth. Additionally, the majority of muscarinic antagonists have a relatively short duration of action requiring that they be administered several times a day. Such a multiple-daily dosing regime is not only inconvenient to the patient but also creates a significant risk of inadequate treatment due to patient non-compliance associated with the frequent repeat dosing schedule.

  • Dialysis cells were then prepared and one half of the cell filled with 750 ⁇ l of dialysis buffer and the other half of the cell with 750 ⁇ l of plasma solution of compound. Once prepared the cells were sealed and placed in an incubator box at 37°C. These cells were then rotated for a minimum of 4 hours to equilibrate.
  • Dunkin-Hartley guinea-pigs 300 - 60Og were supplied by a designated breeding establishment. Animals were dosed with test compound or vehicle either by inhalation in conscious guinea-pigs or by intratracheal instillation (0.5ml/kg) under recoverable gaseous anaesthesia (5% halothane). Animals were allowed to recover from the anaesthesia prior to the measurement of bronchoconstriction. Up to 48 hours post-dosing guinea-pigs were terminally anaesthetized with sodium pentobarbitone (60 mg/kg), the trachea cannulated for artificial ventilation and the jugular vein was cannulated for intravenous administration of methacholine.
  • the guinea-pigs were ventilated using a constant volume respiratory pump (Harvard Rodent Ventilator model 683) at a rate of 60 breath/min and a tidal volume of 5 ml/kg during surgical preparation.
  • Lung function (lung resistance and compliance) was measured in anaesthetised and ventilated guinea-pigs using a pulmonary measurement Flexivent system (SCIREQ, Montreal, Canada) connected to the tracheal cannulae.
  • SCIREQ pulmonary measurement Flexivent system
  • the animals were ventilated (quasi-sinusoidal ventilation pattern) at 60 breaths/min at a tidal volume of 5 ml/kg.
  • a positive end expiratory pressure of 2-3 CmH 2 O was applied.
  • Respiratory resistance was measured using the Flexivent "snapshot" facility (1 second duration, 1 Hz frequency). Lung resistance and compliance was measured before and after intravenous administration of methacholine (3, 10 and 30 ug/kg). The peak increase in resistance following methacholine challenge was calculated and the effect of the test compound on methacholine-induced lung function changes was calculated.
  • Guinea pigs (450-55Og) supplied by Harlan UK or David Hall, Staffs UK and acclimatised to the in-house facilities for a minimum of three days before use. Guinea pigs were randomly assigned into treatment groups and weighed. Each animal was lightly anaesthetised (4% Halothane) and administered compound or vehicle intranasally
  • Saliva production was calculated by subtracting the pre-weighed weight of the pad from each 5 minute period post weighed pad and these numbers added together to produce an accumulation of saliva over 15 minutes. Each 5 minute period could be analysed in addition to the whole 15 minute recording period. Baseline production of saliva was assumed to be constant and multiplied by three to produce a reading for baseline saliva production over 15 minutes.
  • Inhibition of saliva produced by the compound could be calculated by using the following equation: (l-(Test-baseline)/(Veh-baseline))* 100.
