DE19742096A1 - Use of sodium/hydrogen ion exchanger inhibitor to treat and prevent central nervous system disorders, e.g. epilepsy and psychotic disorders - Google Patents

Abstract

An inhibitor of the Na<+>/H<+> exchanger is used for the preparation of a medicament for the treatment or prevention of central nervous system disorders.

Description

The invention describes the use of inhibitors of cellular sodium Hydrogen exchanger for the manufacture of a drug for therapy and Prophylaxis of diseases and disorders caused by hyperexcitability of the Central nervous system triggered, especially for the treatment of Diseases of the epileptic form, centrally triggered clonic and tonic spasms and psychotic disorders.

Inhibitors of the sodium / hydrogen exchanger (NHE) have been in recent years have been characterized in numerous preclinical studies as substances that Reduced blood flow to the heart are aptly suited to this protect endangered heart tissue from destruction. Protection of the Cardiac tissue through NHE inhibitors includes all forms of through the Deficiency-induced damage, starting with Cardiac arrhythmias via hypercontracture of the heart muscle and temporary loss of function up to the death of the heart tissue and associated permanent damage.

The mechanism of action of the NHE inhibitors is that they potentiate the Sodium ion influx, which is caused by a lack of blood supply to tissues Reduce activation of the NHE as a result of intracellular acidification. This will delay the situation of tissue sodium overload. Because sodium and calcium ion transport are coupled with each other in the heart tissue  are the life-threatening calcium overload of the heart cells prevented.

In the same way as at the heart, most of those cited here have already been mentioned Patents also include protection of the central nervous system under the Influence of inhibitors of the NHE described, such active substances the CNS similar to how the heart protects against ischemic conditions. These states will caused by a lack of blood circulation and thus by a deficiency supply of nutrients, oxygen, minerals etc. are particularly pronounced Ischemic damage to the CNS in central infarcts, such as a stroke (Stroke).

With normal healthy blood circulation, therefore, as expected, naturally no protective effects of NHE inhibitors are observed either, since none Ischemic tissue damage to the heart or CNS occurred.

It was therefore surprising that NHE inhibitors, in addition to the protective effects, which only come into effect under conditions of insufficient blood circulation, too direct therapeutic effects against diseases and CNS disorders that are independent of poor circulation conditions and occur in normal, non-ischemic conditions. With these pathological, non-ischemically triggered phenomena that have recently appeared NHE inhibitors can be made available for treatment, it is are diseases and disorders that are significantly caused by hyperexcitability caused by central nervous system neurons. On such Diseases and disorders act by inhibiting the NHE inhibitors Hyperactivity of CNS neurons.

Diseases in which the excitability of overactive neurons is inhibited play a dominant role, belong to the epileptic form, for example the grand mal, the petit mal etc.  

Focal neuronal hyperactivity is not only observed in epilepsy where there is neuronal hyperactivity in the motor cortex and the typical ones Triggers seizures. Other centrally triggered cramps as well Different psychoses were neuronal using appropriate methods Hyperactivity detected in different brain areas. Because the described Principle of action of inhibition of NHE independent of neuronal hyperactivity is able to dampen the trigger or illness, it is not only suitable for the therapy of epilepsy, but also for the treatment of psychoses and mental illnesses in which neuronal hyperactivity is essential pathophysiological role. The resulting indications include the treatment of epilepsy and psychoses such as schizophrenia, Depression and mania, acute arousal and anxiety.

The anti-epileptic and antipsychotic NHE inhibitors can work alone be applied. The unique mechanism of action of the NHE inhibitors but also enables NHE inhibitors to be combined with other active substances, which are based on another mechanism of action. For example Combinations of NHE inhibitors with other anti-epileptic agents Substances, or antipsychotic agents, with anticonvulsants, with Carbonic anhydrase inhibitors etc. cheap therapy schemes and Treatment success allow that with the individual components of the combination cannot be achieved.

NHE inhibitors with their antiepileptic and antipsychotic therapeutic potential show inhibition in the model of the CA3 neurons from Hippocamal Slices epileptiform discharges. Hyperexcitability of Neurons (hyperexcitability) in the form of so-called epileptiform discharges are stimulated by the neuron-stimulating effects of bicuculline, caffeine or triggered low magnesium concentrations. HOE 642, a blocker of the Na⁺ / H⁺ iso form 1, showed a marked inhibition of the excitatory effect these substances caused epileptiform discharges.  

Experimental proof of effectiveness of the damping of neuronal excitation states by NHE inhibitors

On slice preparations of CA3 neurons of the rat hippocampus, the Decreased neuronal excitability tested. Was examined in 8 Experiments the arousal inhibitory effect of Cariporide (HOE 642). The Neural excitability was assessed using intracellular leads based on the spontaneous bioelectric activity, in particular by measuring the action potentials, or by pharmacologically produced epileptoform activity by bicuculline, caffeine or absence of magnesium is assessed. Both the frequency of the spontaneous action potentials as well as the frequency of so-called periodic ones Paroxysmal depolarizations became evident after a wash-in period of 0.1-0.5 mmol Caroporide reversibly reduced by 30-80% over 45 minutes.

A connection between neuronal excitability and inhibition of Na⁺ / H⁺ exchange schers is already suggested in "Suppressive Action of propionate and inhibitors of cellular acid-extrusion mechanisms (IAE) on epileptoform activity of CA3 neurons, Eur. J. Physiol. R 153, P-562, 1997; however, the effect of this is Guanidines and similar compounds are neither anticipated nor suggested.

The known active substances identified as NHE inhibitors are are guanidine derivatives, preferably acylguanidines, including how they described in the following publications and patent publications: Edward J. Cragoe, Jr., "DIURETICS, Chemistry, Pharmacology and Medicine," J. WILEY & Sons (1983), 303-341, also for compounds of the following formulas:
