Abstract

Objective: to study the ability of imidazo [1,2-a]azepinium derivatives for myocardium preconditioning. Material and methods. 9 imidazo [1,2-a]azepinium derivatives, purebred laboratory rats, perfusion technique of the isolated rat heart in constant pressure, measuring of the contractile activity of the heart using a latex cylinder introduced into the left ventricle. Results. The derivatives IFT_000280 and IFT_000281 raised the left ventricular pressure by 20-80 % depending on the dose. These derivatives showed considerable coronarodilatative activity that exceeded that for phlocaline (reference compound, ATP-dependent potassium channels activator). Used at the concentrations of 1×10-5 mole/l, they considerably (twice/thrice as much) increased the duration of contraction of isolated hearts in total ischemia in comparison with other studied compounds by 32-38 % compared to the control group. Conclusion. Taking into account our results, we decided to choose the compounds IFT_000280 and IFT_000281 as the most promising for the myocardium preconditioning and to carry out further investigation.
