Description

TRISUBSTITUTED FUROPYRAMIDINES AND THEIR USE AS ACTIVATORS OF THE IP RECEPTOR

The present application relates to novel 4,5,6-trisubstituted furo [2,3-d] pyrimidine derivatives, processes for their preparation, their use for the treatment and / or prophylaxis of diseases, and their use for the preparation of medicaments for the treatment and / or prophylaxis of diseases, in particular for the treatment and / or prophylaxis of cardiovascular diseases.

Prostacyclin (PGI ₂ ) belongs to the family of bioactive prostaglandins, which are derivatives of arachidonic acid. PGI ₂ is the major product of arachidonic acid metabolism in endothelial cells and has potent vasodilating and anti-aggregating properties. PGI ₂ is the physiological antagonist of thromboxane A ₂ (TxA ₂ ), a potent vasoconstrictor and platelet aggregation stimulator, thus contributing to the maintenance of vascular homeostasis. A reduction in PGI ₂ levels is probably responsible for the development of various cardiovascular diseases [Dusting, GJ. et al., Pharmac. Ther. 1990, 48: 323-344; Vane, J. et al., Eur. J. Vase. Endovasc. Surg. 2003, 26: 571-578].

After release of arachidonic acid from phospholipids via phospholipases A ₂ PGI ₂ is synthesized by cyclooxygenases and then by the PGI ₂ synthase. PGI ₂ is not stored, but released immediately after synthesis, causing its effects locally. PGI ₂ is an unstable molecule that is rapidly (half-life about 3 minutes) non-enzymatically rearranged to an inactive metabolite, 6-keto-prostaglandin Fl alpha [Dusting, GJ. et al., Pharmac. Ther. 1990, 48: 323-344].

The biological effects of PGI ₂ are due to the binding to a membrane-bound receptor, the so-called prostacyclin or IP receptor [Narumiya, S. et al., Physiol. Rev. 1999, 79: 1193-1226]. The IP receptor belongs to the G protein-coupled receptors that are characterized by seven transmembrane domains. In addition to the human IP receptor, rat and mouse prostacyclin receptors have also been cloned [Vane, J. et al., Eur. J. Vase. Endovasc. Surg. 2003, 26: 571-578]. In smooth muscle cells, activation of the IP receptor leads to stimulation of adenylate cyclase, which catalyzes the formation of cAMP from ATP. The increase in the intracellular cAMP concentration is responsible for the prostacyclin-induced vasodilation and the inhibition of platelet aggregation. In addition to the vasoactive properties, PGI ₂ still has anti-proliferative [Schroer, K. et al., Agents Actions Suppl. 1997, 48: 63-91; Kothapalli, D. et al., Mol. Pharmacol. 2003, 64: 249-258; Planchon, P. et al., Life Sei. 1995, 57: 1233-1240] and anti-arteriosclerotic effects [Rudic, RD et al., Circ. Res. 2005, 96: 1240-1247; Egan KM et al., Science 2004, 114: 784-794]. In addition, metastasis formation is inhibited by PGI ₂ [Schneider, MR et al., Cancer Metastasis Rev. 1994, 13: 349-64). Whether these effects are due to stimulation of cAMP production or by IP receptor-mediated activation of other signal transduction pathways in the respective target cell [Wise, H. et al. TIPS 1996, 17: 17-21], such as the phosphoinositide cascade and potassium channels, is unclear.

Although the overall effects of PGI _{2 are} therapeutically useful, clinical use of PGI ₂ is severely limited by its chemical and metabolic instability. More stable PGI ₂ analogs such as iloprost [Badesch, DB et al., J. Am. Coli. Cardiol. 2004, 43: 56S-61S] and treprostinil [Chattaraj, SC, Curr. Opion. Invest. Drugs 2002, 3: 582-586] could be made available, but the duration of these compounds is still very short. Also, the substances can be administered to the patient only via complicated routes of administration, such as by continuous infusion, subcutaneously or via repeated inhalations. These routes of administration can also lead to additional side effects, such as infections or pain at the injection site. The use of the only PGI ₂ derivative orally available to the patient, beraprost [Barst, RJ. et al., J. Am. Coli. Cardiol. 2003, 41: 2119-2125], again limited by its short duration of action.

The object of the present invention is to provide new substances which act as chemically and metabolically stable, orally available activators of the IP receptor and are suitable as such for the treatment of diseases, in particular of cardiovascular diseases.

The parenteral administration can be done bypassing a resorption step (eg, intravenous, intraarterial, intracardiac, intraspinal, or intralumbar) or with involvement of resorption (eg, intramuscular, subcutaneous, intracutaneous, percutaneous, or intraperitoneal). For the paren- tereral administration are suitable as application forms, inter alia, injection and infusion preparations in the form of solutions, suspensions, emulsions, lyophilisates or sterile powders.

For the other routes of administration are suitable, for example Inhalation medicines (including powder inhalers, nebulizers), nasal drops, solutions or sprays, lingual, sublingual or buccal tablets, films / wafers or capsules, suppositories, ear or ophthalmic preparations, vaginal capsules, aqueous suspensions (lotions, shake mixtures), lipophilic suspensions, ointments, creams, transdermal therapeutic systems (eg plasters), milk, pastes, foams, powdered powders, implants or stents.

Preference is given to oral or parenteral administration, in particular oral and intravenous administration.

The compounds according to the invention can be converted into the stated administration forms. This can be done in a conventional manner by mixing with inert, non-toxic, pharmaceutically suitable excipients. These adjuvants include, among others. Excipients (for example microcrystalline cellulose, lactose, mannitol), solvents (for example liquid polyethylene glycols), emulsifiers and dispersants or wetting agents (for example sodium dodecyl sulfate, polyoxysorbitanoleate), binders (for example polyvinylpyrrolidone), synthetic and natural polymers (for example albumin), Stabilizers (eg, antioxidants such as ascorbic acid), dyes (eg, inorganic pigments such as iron oxides) and flavor and / or odoriferous.

In general, it has proven to be advantageous, when administered parenterally, to administer amounts of about 0.001 to 1 mg / kg, preferably about 0.01 to 0.5 mg / kg of body weight, in order to achieve effective results. When administered orally, the dosage is about 0.01 to 100 mg / kg, preferably about 0.01 to 20 mg / kg and most preferably 0.1 to 10 mg / kg of body weight.

Nevertheless, it may be necessary to deviate from the stated amounts, depending on body weight, route of administration, individual behavior towards the active ingredient, type of preparation and time or interval at which the application is carried out. Thus, in some cases it may be sufficient to manage with less than the aforementioned minimum amount, while in other cases, the said upper limit must be exceeded. In the case of the application of larger quantities, it may be advisable to distribute these in several single doses throughout the day.

B. Evaluation of Pharmacological Activity

The pharmacological activity of the compounds according to the invention can be demonstrated in the following assays:

BI. Binding studies with prostacyclin receptors (EP receptors) of human thrombocyte membranes

To obtain platelet membranes, 50 ml of human blood (buffy coats with CDP stabilizer, Maco Pharma, Langen) are centrifuged for 20 min at 160 × g. The supernatant (platelet-rich plasma, PRP) is removed and then centrifuged again at 2000 xg for 10 min at room temperature. The sediment is dissolved in 50 mM tris (hydroxymethyl) amino methane, which is adjusted with 1N hydrochloric acid to a pH of 7.4, re-suspended and stored at -20 ⁰ C overnight. The following day, the suspension is centrifuged at 80,000 xg and 4 ° C for 30 minutes. The supernatant is discarded. The sediment is re-suspended in 50 mM tris- (hydroxymethyl) -aminomethane / hydrochloric acid, 0.25 mM ethylenediaminetetraacetic acid (EDTA), pH 7.4 and then centrifuged again at 80,000 × g and 4 ° C. for 30 minutes. The membrane bransediment is added to binding buffer ((50 mM Tris-hydroxymethyl) aminomethane / hydrochloric acid, 5 mM magnesium chloride, pH 7.4) and stored at -70 ⁰ C until the binding assay.

For the binding experiment, 3 mM ³ H-iloprost (592 GBq / mmol, Amersham Bioscience) are incubated for 60 min with 300-1000 μg / ml human platelet membranes per batch (maximum 0.2 ml) in the presence of the test substances at room temperature. After stopping, the membranes are mixed with cold binding buffer and washed with 0.1% bovine serum albumin. After addition of Ultima Gold scintillator, the radioactivity bound to the membranes is quantified by means of a scintillation counter. Non-specific binding is defined as radioactivity in the presence of 1 μM iloprost (Cayman Chemical, Ann Arbor) and is typically <25% of the total bound radioactivity. The binding data (IC ₅₀ values) are determined by means of the program GraphPad Prism Version 3.02.

Representative results for the compounds according to the invention are listed in Table 1: Table 1

B-2. EP receptor stimulation on whole cells

The IP agonist activity of test substances is determined using the human erythroleukemia cell line (HEL), which endogenously expresses the IP receptor [Murray, R., FEBS Letters 1989, 1: 172-174]. For this purpose, the suspension cells (4 x 10 ⁷ cells / ml) in buffer [10 mM HEPES (4- (2-hydroxyethyl) -1-piperazinethansulfonsäure) / PBS (phosphate-buffered saline, Fa. Oxoid, UK)], 1 mM Calcium chloride, 1 mM magnesium chloride, 1 mM EBMX (3-isobutyl-l-methylxanthine), pH 7.4, with the respective test substance for 5 minutes at 30 ⁰ C incubated. Subsequently, the reaction is stopped by addition of 4 ° C cold ethanol and the mixtures stored for a further 30 minutes at 4 ° C. Thereafter, the samples are centrifuged at 10,000 xg and 4 ° C. The resulting supernatant is discarded and the sediment used to determine the concentration of cyclic adenosine monophosphate (cAMP) in a commercially available cAMP radioimmunoassay (IBL, Hamburg). IP agonists increase the cAMP concentration in this test, IP antagonists are ineffective. The effective concentration (EC _5O values) is determined using the program GraphPad Prism Version 3.02.

B-3. Thrombocyte aggregation inhibition in vitro

To determine the antiplatelet activity, blood from healthy volunteers of both sexes is used. One part of 3.8% sodium citrate solution as coagulant is mixed with 9 parts of blood. The blood is centrifuged at 900 rpm for 20 min. The pH of the recovered platelet-rich plasma is adjusted to pH 6.5 with ACD solution (sodium citrate / citric acid / glucose). The platelets are then centrifuged off, taken up in buffer and centrifuged again. The thrombocyte ene precipitate is taken up in buffer and additionally re-suspended with 2 mmol / l calcium chloride.

For the aggregation measurements, aliquots of the platelet suspension are incubated with the test substance at 37 ° C. for 10 min. Subsequently, the aggregation by addition of ADP and determined by the turbidimetric method according to Born in the aggregometer at 37 ° C [Born GVR, J. Physiol. (London) 168, 178-179 (1963)].

B-4. Blood pressure measurement on anesthetized rats

Male Wistar rats weighing 300-350 g are anesthetized with thiopental (100 mg / kg i.p.). After tracheostomy, the femoral artery is catheterized for blood pressure measurement. The substances to be tested are administered as a solution orally by gavage or via the femoral vein intravenously in a suitable vehicle.

B-fifth PAH model in anesthetized dog

In this animal model of pulmonary arterial hypertension (PAH), Mongrel dogs with a body weight of about 25 kg are used. The anesthesia is induced by slow intravenous administration of 25 mg / kg of sodium thiopental (Trapanal ^®) and (ferin Alio ^®) 00:15 mg / kg alcuronium chloride and maintained throughout the experiment by means of a continuous infusion of 0.04 mg / kg / hr fentanyl ^® , 0.25 mg / kg / h droperidol (dehydrobenzperidol ^® ) and 15 μg / kg / h alcuronium chloride (Alloferin ^® ). Reflective effects on the heart rate by lowering blood pressure are minimized by autonomic blockade [continuous infusion of atropine (about 10 μg / kg / h) and propranolol (about 20 μg / kg / h)]. After intubation, the animals are ventilated via a respirator with a constant breathing volume, so that an end-tidal CO ₂ concentration of about 5% is achieved. Ventilation takes place with room air, enriched with approx. 30% oxygen (normoxie). To measure the hemodynamic parameters, a catheter filled with fluid is implanted in the femoral artery to measure blood pressure. A dual lumen Swan-Ganz catheter ^® is jugularis on the V. in the pulmonary artery is flooded (distal lumen for measuring the pulmonary arterial pressure, proximal lumen for measuring the central venous pressure). Left ventricular pressure is measured after the introduction of a Mikro-Tip catheter (Millar Instruments ^®) through the carotid artery into the left ventricle and derived from the dP / dt value as a measure of contractility. Substances are administered iv via the femoral vein. The hemodynamic signals are recorded and evaluated by means of pressure transducers / amplifiers and PONEMAH ^® as data acquisition software.

To induce acute pulmonary hypertension, either hypoxia or a continuous infusion of thromboxane A ₂ or a thromboxane A ₂ analogue is used as the stimulus. Acute hypoxia is induced by gradual lowering of the oxygen in the ventilation air to about 14%, so that the mPAP increases to values of> 25 mm Hg. In the case of a thromboxane A ₂ analogue stimulus, 0.21-0.32 μg / kg / min U-46619 [9, 11-dideoxy-9α, 11α-epoxy-methano-prostaglandin F _2α (Sigma)] is infused to obtain to increase the mPAP to> 25 mm Hg. B-sixth PAH model in anesthetized Göttinger Minipig

In this animal model of pulmonary arterial hypertension (PAH), Göttingen mini-pigs with a body weight of approx. 25 kg are used. The anesthesia is induced by 30 mg / kg Ketamine (Ketavet ^®) in, followed by an intravenous administration of 10 mg / kg of sodium thiopental (Trapanal ^®); it is maintained during the experiment by inhalation anesthesia from enflurane (2-2.5%) in a mixture of room air enriched with approximately 30-35% oxygen / N ₂ O (1: 1.5). To measure the hemodynamic parameters, a catheter filled with fluid is implanted in the carotid artery to measure blood pressure. A dual lumen Swan-Ganz catheter ^® is jugularis on the V. in the pulmonary artery is flooded (distal lumen for measuring the pulmonary arterial pressure, proximal lumen for measuring the central venous pressure). Left ventricular pressure is measured after the introduction of a Mikro-Tip catheter (Millar Instruments ^®) through the carotid artery into the left ventricle and derived from the dP / dt value as a measure of contractility. Substances are administered iv via the femoral vein. The hemodynamic signals are recorded and evaluated by means of pressure-sensitive devices / amplifiers and PONEMAH ^® as data acquisition software.

To induce acute pulmonary hypertension, a continuous infusion of a thromboxane A ₂ analogue is used as the stimulus. Here, 0.12-0.14 μg / kg / min of U-46619 [9, 11-dideoxy-9α, 11α-epoxymethano-prostaglandin F _2α (Sigma)] is infused to increase the mPAP to> 25 mm Hg.
