where X, O, NH or CH2. Reagent 1:5 - hydroxynicotinic acid. Reagent 2: morphology. Reaction conditions: under stirring at an elevated temperature. 5 table. The invention relates to the synthesis of biologically active compounds, namely, salts of nitrogen-containing heterocyclic derivatives and 5-hydroxynicotinic acid of General formula:
< / BR>where X 0(1a), CH2(1B), NH(1B).has antianginal and antiarrhythmic activity.These properties suggest the possibility of using the compounds for treatment of ischemic heart disease and arrhythmias.Known means inderal showing antianginal and antiarrhythmic activity, but has a relatively high toxicity and cardiodepressive action.The purpose of the invention, the search and synthesis of new compounds with antianginal and antiarrhythmic properties, low toxic the x compounds by the interaction of 5-hydroxynicotinic acid with the corresponding cyclic amines in the presence of a solvent under heating.Compounds are white crystalline substances, soluble in water and alcohol.P R I m e R 1. To a mixture of 40 mmol of 5-hydroxynicotinic acid in 200 ml of atacora add 40 mmol of the research or piperidine, or piperazine. The reaction mixture was stirred 15 min at 76-78oC, treated with 1 g of activated charcoal, filtered, the filtrate evaporated to a residual volume of 50 ml, cooled to 5-7oC, the target product is separated, dried, get, respectively: morpholino-5-hydroxynicotinate 1A, piperidine-5-hydroxynicotinate (1B) and piperazine-5 - hydroxynicotinate (1B).Physico-chemical data and results of analyses are given in table. 1.P R I m m e R 2. The study of the cardioprotective action of heterocyclic derivatives of 5-hydroxynicotinic acid.Determination of acute toxicity.Studied the acute toxicity of substances in experiments on white mice weighing 18-20 g with the definition of LD50according to the method of Litchfield and Wilcoxon signed intraperitoneal injection. Observation of animals should be performed within 48 h after injection of the drug. The results are shown in table.2 and indicate low toxicity of the claimed compounds.eriment put on rabbits of the Chinchilla breed weighing 3-3 .5 kg with pre-implanted in the coronary artery by occluder (Y. B. Rozanov, T. C. Morozova "Bulletin of experimental biology and medicine, 1984, 10, S. 460-462). Compound is injected immediately after the establishment of stable threshold myocardial ischemia (table. 3).1A at a dose of 0.2 mg/kg in all 4 experiments consistently increased the threshold for myocardial ischemia in experimental animals with duration of antianginal effect 15-20 minutes 1B in a dose range of 0.2 to 5 mg/kg had antianginal effect in all experimental animals, and the duration of prophylactic anti-ischemic action of the compounds increased with increasing dose in the dose of 5 mg/kg over 60 minutes 1B in a dose of 0.2 mg/kg had antianginal effect of duration of 15-20 min, and at a dose of 1 mg/kg 30-40 minutesComparison drug from the group of --blockers inderal in effective anti-ischemic dose of 1 mg/kg steadily increased the threshold of an ischemia of a myocardium of rabbits with a duration of antianginal effect 30-40 minutesThus, studies have shown that the heterocyclic derivatives of 5-hydroxynicotinic acids have antianginal effect and are not inferior in efficacy to the comparator drug from the group of --blockers.2. Antiarrhythmic activity of what you put on bisexual Wistar rats, mass 160-240 g, anesthetized by intraperitoneal injection of sodium thiopental dose of 50 mg/kg Occlusion of the descending branch of the left coronary artery is performed during artificial ventilation of the lungs. Produce thoracotomy in the fourth intercostal space to the left and opened the pericardium. Under the anterior descending branch of the left coronary artery at the level of the left atrial appendage down the thread using atraumatic needles. In experiments on rats coronary flow block for 10 min, after which the circulation is restored and continue to monitor the heart rate during the next 5 minutesCompound injected, inkjet, simultaneously for 5 min prior to occlusion of a coronary artery (the EYE).Comparison drug inderal slowly injected directly in front of the EYE.The results are shown in table. 4, 5. At intravenous introduction of the claimed compounds in doses of 5% LD50not registered cardiodepressive effect on the basic electrophysiological parameters of the heart muscle. On the model of early postocclusion arrhythmias, all compound at a dose of 5% LD50showed antifibrillatory effect, and the compound 1A was significantly (the awn ventricular arrythmia (GA). 1B reduced the duration of adipose tissue, reduced the intensity IA and 1B reduced the intensity IA. In isomolar doses (for 1A and 1B is approximately equal to 2% LD50) have been the most effective compounds 1A and 1B, which together with antifibrillatory effect reduced the duration of VT and intensity IE. Comparison drug inderal dose of 1.0 mg/kg showed a cardiotoxic effect, which was expressed in the impaired function of the conductance of myocardium. At this dose inderal had antifibrillatory effect and significantly (p < 0,05) was affected only for the duration of VT and intensity IA, i.e. inferior to one of the claimed compounds (1A).Dose not calling cardiodepressive effect (0.1 mg/kg), inderal significantly (p < 0,05) was affected only on the latent period of arrhythmia, i.e., inferior in the efficiency of the claimed compounds.On the model of reperfusion arrhythmias among the tested compounds, taken in isotoxicity doses (5% LD50the most effective was the connection 1B, which was significantly (P < 0,05) reduced the incidence of ventricular fibrillation (Fi), duration adipose tissue and the intensity IA and increased latent period. In isomolar doses (about 2% LD50) the greatest effect was shown by the compounds comparison of inderal dose of 1 mg/kg (causing dysfunction of the conductance of myocardium) reduced the incidence of Fi, extended latent period and reduced the duration of VT, i.e., the characteristic of the antiarrhythmic actions yielded compound 1B in a dose of 5% LD50. At a dose of 0.1 mg/kg inderal yielded in the antiarrhythmic activity of the claimed compounds.Thus, the claimed heterocyclic derivatives of 5-hydroxynicotinic acid, have antianginal and antiarrhythmic properties. On antianginal activity of these compounds do not yield --the blocker inderal and have much lower toxicity. In the investigated dose range of the claimed compounds do not show cardiotoxic properties are not inferior, and in some cases superior to antiarrhythmic activity of inderal. When you save the spectrum and intensity of antiarrhythmic effect of these compounds less toxic compared with similar-blocker-inderal and isoeffective doses not have cardiodepressive effect.
