Definitions

• the present invention relates to the use of compounds of the formulas I-VI for the manufacture of a medicament for the treatment of acute and chronic lung diseases such as the respiratory distress syndrome (acute acute respiratory distress syndrome (ARDS)) and the treatment of COPD ,
• ARDS acute acute respiratory distress syndrome
• COPD COPD
• noxae directly harmful to the lungs may cause ALI or ARDS, respectively.
• an acute lung disease associated with bilateral infiltrates in chest x-ray and severely impaired respiration after exposure to one of the above-mentioned noxae at a ratio of PaCvFiO 2 ⁇ 300 is said to be ALI, at a ratio of PaO 2 : FiO 2 ⁇ 200 from an ARDS.
• the associated mortality is given as more than 50% and thus represents a serious intensive medical illness.
• Pathophysiological findings include diffuse alveolar damage with invasion of neutrophils, macrophages, erythrocytes, hyaline membrane formation, leakage of high-protein edema fluid, and interruption of the alveolar epithelial barrier with pathologically increased permeability. Histologically, after the stage of pulmonary edema formation, there is an acute and chronic inflammatory reaction with a possible transition to fibrosis. Clinically, a drastically deteriorated gas exchange with reduced oxygenation and difficult ventilation through a disturbed ventilation-perfusion distribution. Most ALI / ARDS patients also have moderate pulmonary hypertension with increased pulmonary resistance, which is due to hypoxic vasoconstriction, destruction and obstruction of the pulmonary alveolar endothelium. In some ALI / ARDS patients, this can lead to right heart failure.
• cGMP cyclic guanosine monophosphate
• NO nitric oxide
• GTP guanosine triphosphate
• the soluble guanylate cyclases consist of two subunits and most likely contain heme per heterodimer, which is part of the regulatory center. This is central to the activation mechanism. NO can bind to the iron atom of the heme and thus significantly increase the activity of the enzyme. Heme-free preparations, on the other hand, can not be stimulated by NO. CO is also able to attack the iron central atom of the heme, whereby the stimulation by CO is much better than that by NO.
• guanylate cyclase plays a crucial role in different physiological processes
• the activators of soluble guanylate cyclase according to the invention are particularly suitable for the preparation of pharmaceutical substances / medicaments for lowering pulmonary hypertension.
• the compounds of the formula I have to VI Regarding Improved Pharmacodynamic Properties 1
• they exert pressure-lowering effects in the pulmonary-arterial circulation independently of the endogenous NO produced in the pulmonary circulation.
• the stimulators of soluble guanylate cyclase enhance the effect of the endogenously produced NO and improve gas turnover through selective pulmonary vascular dilation of the ventilated areas, resulting in a reduction of the intrapulmonary shunt with an increase in oxygenation.
• Cigarette smoke causes COPD as exogenous noxa
• Genetic factors such as ⁇ Xi-antitrypsin deficiency or bronchial hyperreactivity play a minor role
• Chronic bronchitis, fibrosing bronchiolitis and the Emphysema are the three pathological features of COPD, which contribute to a progressive and accelerated loss of forced endospasm vitality (FeVi)
• cough and sputum are present for at least 3 months per year for at least two consecutive years.
• dyspnoea occurs, first under stress, later also at rest.
• Pulmonary vascular remodeling in COPD with fntimahyperplasia and medial hypertrophy is associated with chronic hypoxia, nicotine inflammatory stimuli and frequent bacterial exacerbations as well as hyperextension and airways obstruction.
• moderate pulmonary arte- nal pressures greater than 40 mmHg are not uncommon in patients with at least one episode of acute respiratory failure
• inhalative glucocorticoids are used to reduce the frequency of exacerbations and antibiotics in bacterial bronchitis or pneumonia to reduce the so-called dynamic hypnosis Disease can not be significantly influenced by any of the established therapeutic principles.
• Long-term oxygen therapy is recommended if P A O 2 falls below 55 mmHg in respiratory global failure. Consistently applied, this therapy improves the prognosis, but it can not influence the remodeling of all layers of the pulmonary artery walls.
• the soluble guanylate cyclase activators according to the invention are particularly suitable for the production of pharmaceutical substances / medicaments for the reduction of pulmonary hypertension.
• the compounds of the formulas I to VI according to the invention have improved pharmacodynamic properties on the one hand irrespective of the endogenously produced in the pulmonary circulation NO even in severe endothelial damage and advanced disease pressure lowering in the pulmonary-artellen circulation addition strengthen the stimulators of the soluble guanylate cyclase the effect of the endogenously produced NO and thereby improve the gas exchange by a selective pulmonary vascular dilatation of the ventilated areas, which leads to a reduction of the intrapulmonary shunt with an increase in the oxy- gen.
