Description

[Technical field]

[0001] The present invention relates to combinations of selective blockers of TASK-1 and TASK-3 channels, in particular substituted imidazo[1,2-a]pyrimidine derivatives and substituted imidazo[1,2-a]pyridine derivatives of formula (I) and P2X3 receptor antagonists, for the treatment and / or prevention of sleep-related breathing disorders, preferably obstructive sleep apnea and central sleep apnea and snoring. [Background technology]

[0002] 2. Background of the Invention Obstructive sleep apnea (OSA) is a sleep-related respiratory disorder characterized by repeated episodes of upper airway obstruction. When breathing, the patency of the upper airway is ensured by the interplay of two opposing forces. The dilator action of the upper airway musculature opposes the negative intraluminal pressure that constricts the lumen. The active contraction of the diaphragm and other accessory respiratory muscles generates a negative pressure in the airway and thus constitutes the driving force of breathing. The stability of the upper airway is substantially determined by the coordination and contraction properties of the dilator muscles of the upper airway.

[0003] Upper airway collapse in OSA is thought to occur at sleep onset due to a decrease in the activity of several upper airway dilator muscles, resulting in an inability to maintain the anatomically vulnerable airway open. However, several upper airway dilator muscles, including the genioglossus, the most important of the upper airway dilator muscles and innervated by the hypoglossal nerve, can increase their activity during sleep in response to respiratory stimuli, potentially countering some of these changes at sleep onset. OSA patients were observed to have apnea intervals with only 25-40% higher genioglossus activity compared to sleep periods with frequent obstructive apneas (Jordan AS, White DP, Lo YL, et al. Airway dilator muscle activity and lung volume during stable breathing in obstructive sleep apnea. Sleep 2009, 32(3):361-8).

[0004] The mechanism for activating the genioglossus muscle and maintaining airway patency relies on negative pressure-sensitive nerve endings / mechanoreceptors located in the pharyngeal mucosa. When small negative pressures are detected during the respiratory cycle, these receptors generate excitatory motor nerve output to the genioglossus muscle via the negative pressure reflex.

[0005] The genioglossus muscle plays a crucial role in the pathogenesis of obstructive sleep apnea. The activity of this muscle increases with a decrease in intrapharyngeal pressure, in the sense of an expansion compensatory mechanism. It is innervated by the hypoglossal nerve and drives the tongue forward and downward, thus widening the pharyngeal airway [Verse et al., Somnologie 3, 14-20 (1999)]. The tone of the expansion muscles of the upper airway is regulated, among other things, via mechanoreceptors / stretch receptors / nerve endings in the nasal cavity / pharynx [Bouillette et al., J. Appl. Physiol. Respir. Environ. Exerc. Physiol. 46, 772-779 (1979)]. In sleeping patients suffering from severe sleep apnea, further reduction in genioglossus activity was observed during local anesthesia of the upper airway [Berry et al., Am. J. Respir. Crit. Care Med. 156, 127-132 (1997)].

[0006] In a sleep apnea model in anesthetized pigs, intranasal administration of potassium channel blockers that block TASK-1 channels in the nanomolar range led to inhibition of the collapsibility of the pharyngeal respiratory musculature and sensitization of the negative pressure reflex of the upper airway. It is hypothesized that intranasal administration of potassium channel blockers sensitizes mechanoreceptors / nerve endings in the upper airway and, via activation of the negative pressure reflex, leads to increased activity of the upper airway musculature, thereby stabilizing the upper airway and inhibiting collapse. Due to this stabilization of the upper airway, TASK channel blockade may also be crucial for obstructive sleep apnea and snoring [Wirth et al., Sleep 36, 699-708 (2013); Kiper et al., Pflugers Arch. 467, 1081-1090 (2015)].

[0007] Of particular interest are the TASK (TWIK-related acid-sensitive K+ channels) subfamily, TASK-1 (KCNK3 or K2P3.1) and TASK-3 (KCNK9 or K2P9.1). Functionally, these channels are characterized by having a "leak" or "background" stream flowing through them during the maintenance of voltage-independent kinetics, and by responding to numerous physiological and pathological influences by increasing or decreasing their activity. A hallmark of TASK channels is their sensitive response to changes in extracellular pH: at acidic pH the channels are inhibited, and at alkaline pH they are activated.

[0008] TASK-1 and TASK-3 channels also play a role in respiratory regulation. Both channels are expressed in respiratory neurons of the respiratory center of the brainstem, in particular in neurons that generate respiratory rhythms (the ventral respiratory group with the pre-Bötzinger complex), and in the noradrenergic locus coeruleus, as well as in serotonergic neurons of the raphe nucleus. Due to their pH dependence, TASK channels here have the function of sensors that convert changes in extracellular pH into corresponding cellular signals [Bayliss et al., Pflugers Arch. 467, 917-929 (2015)]. TASK-1 and TASK-3 are also expressed in the carotid body (Glomus caroticum), a peripheral chemoreceptor that measures the pH, O2 and CO2 content of blood and transmits signals to the respiratory center of the brainstem to regulate breathing. TASK-1 knockout mice have been shown to have reduced ventilatory responses (increased respiratory rate and tidal volume) to hypoxia and normoxic hypercapnia [Trapp et al., J. Neurosci. 28, 8844-8850 (2008)]. Furthermore, TASK-1 and TASK-3 channels have been demonstrated in motor neurons of the hypoglossal nerve, the 12th cranial nerve that has a key role in keeping the upper airway open [Berg et al., J. Neurosci. 24, 6693-6702 (2004)].

[0009] Increasing the activity of upper airway muscles by blocking TASK1 and TASK3 channels can stabilize the upper airways and protect them from collapse and obstruction. Furthermore, snoring can also be suppressed by mechanisms of upper airway stabilization.

[0010] For simple snoring, there is no obstruction of the upper airway. When the upper airway narrows, the inhalation and exhalation flow rates increase. This, along with the relaxed muscles, causes the soft tissues of the mouth and throat to flap in the airflow. This slight vibration produces the typical snoring sound.

[0011] Obstructive snoring (upper airway resistance syndrome, heavy snoring, hypopnea syndrome) is caused by recurrent partial obstruction of the upper airway during sleep. This results in an increase in airway resistance and therefore an increase in the work of breathing with significant intrathoracic pressure fluctuations. The development of negative intrathoracic pressure during inspiration can thereby reach values ​​that result from complete airway obstruction in OSA. The pathophysiological effects on the heart, circulation and sleep quality are the same as in obstructive sleep apnea. The etiology is likely to be the same as in OSA. Obstructive snoring is often a precursor to OSA (Hollandt JH et al., Upper airway resistance syndrome (UARS)-obstructive snoring. HNO 2000, 48(8):628-634).

[0012] Central sleep apnea (CSA) occurs as a result of impaired brain function or respiratory control. CSA is characterized by a lack of respiratory drive during sleep, resulting in recurrent periods of insufficient or complete ventilation and impaired gas exchange. CSA has several manifestations. These include high altitude induced periodic breathing, idiopathic CSA (ICSA), opiate-induced central apnea, obesity hypoventilation syndrome (OHS), and Cheyne-Stokes respiration (CSB). Although the exact mechanisms involved in the various types of CSA can vary considerably, unstable ventilatory drive during sleep is the major underlying feature (Eckert DJ et al., Central sleep apnea:Pathophysiology and treatment. Chest 2007, 131(2):595-607).

[0013] Furthermore, obstructive sleep apnea has been associated with hyperactivation of the carotid body, and P2X3 ATP receptors in the carotid body have been found to contribute to increased chemoreflex hypersensitivity (SV Conde et al., Purines and carotid body: New Roles in Pathological conditions. Front. Pharmacol. 2017, 8:913, published online December 12, 2017. 4doi:10.3389 / fphar.2017.00913). P2X3 receptor antagonism was shown to reduce the frequency of apnoeas and significantly improve respiratory regularity compared to placebo in newborn rats (Plkatayama et al., P2X3 receptor antagonism reduces the occurrence of apnoeas in newborn rats. Respir Physiol Neurobiol. 2020, Jun;277:103438. Published online April 5. doi:10.1016 / j.resp.2020.103438). P2X3 receptor antagonists are a class of drugs that inhibit ATP-mediated actions on P2X3 and P2X2 / 3 receptors. (A. Spinaci et al., P2X3 Receptor Ligands: Structural Features and Potential Therapeutic Applications. 2021, Front Pharmacol.;12:653561. Published online April 13. doi:10.3389 / fphar.2021.653561).

[0014] P2X3 receptor antagonists have been described in the literature as drugs for the treatment of chronic cough, bladder disorders, osteoarthritis, cystic fibrosis, diabetic neuropathy and endometriosis (A. Spinaci et al., P2X3 Receptor Ligands: Structural Features and Potential Therapeutic Applications. 2021, Front Pharmacol.,;12:653561. Published online April 13. doi:10.3389 / fphar.2021.653561).

[0016] The current gold standard treatment for patients with OSA is continuous positive airway pressure (CPAP). The positive airflow pressure generated by the airflow turbine pump splint opens the upper airway and reverses all potential causes of pharyngeal collapse, thereby preventing hypopnea, apnea, and sleep fragmentation. Unfortunately, up to 50% of patients with OSA cannot tolerate CPAP for long periods of time (M. Kohler, D. Smith, V. Tippett et al., Thorax 2010 65(9):829-32:Predictors of long-term compliance with continuous positive airway press). Thus, there remains a need to find effective therapeutic agents for the treatment and / or prevention of sleep-related breathing disorders, such as obstructive sleep apnea. Thus, the object of the present invention is to provide an effective therapeutic agent for the treatment and / or prevention of sleep-related breathing disorders, such as obstructive sleep apnea, central sleep apnea, and snoring.

[0017] Surprisingly, it has now been found that the combination of TASK1 / 3 channel blocker and P2X3 receptor antagonist suppresses upper airway collapsibility with improved efficacy compared to each treatment alone, and is therefore suitable for the manufacture of a medicament for use in the treatment and / or prevention of sleep-related breathing disorders, preferably obstructive and central sleep apnea and snoring.It has been found that the synergistic effect of the combination of TASK1 / 3 channel blocker and P2X3 receptor antagonist allows the dose of each treatment to be reduced compared to each treatment alone.
