| description | Relevance. Cyclic 3′,5′-guanosine monophosphate is a secondary intracellular messenger that plays a key role in many physiological processes.Quantitative determination of the level of c-GMP in the tissues of laboratory animals is an urgent task of experimental pharmacology and physiology.Purpose of the study. Development of a method for the quantitative determination of cyclic guanosine monophosphate in various tissues of rats using high performance liquid chromatography with mass spectrometric detection.Methods. The biomaterial was homogenized with deionized water. Extraction of c-GMP from homogenates was performed with methanol, acyclovir was used as an internal standard. Detection of c-GMP and acyclovir was performed using a Sciex QTrap 3200MD mass spectrometer, chromatographic separation was performed using an Agilent Technologies 1260 Infinity II HPLC. The mobile phase was methanol and deionized water.Results. Detection of c-GMP was performed by MRM transitions m/z 346.2/152.1; 346.2/135.1, chromatographic determination of c-GMP was performed in reverse phase mode on an Agilent InfinityLab Poroshell 120 EC-C18 4.6×100 mm, 2.7 µm column. The retention time of c-GMP and acyclovir was 7.85 and 7.45 minutes, respectively, the total duration of the chromatographic analysis was 12 minutes. The analytical range of the procedure for determining c-GMP in homogenates was 0.5–1000.0 pmol/ml. The content of c-GMP in the tissues of intact Wistar rats was analyzed using the developed method.Conclusion. The developed bioanalytical HPLC-MS/MS method for the quantitative determination of c-GMP fully complies with the validation requirements. The metrological characteristics of the method make it possible to estimate the content of c-GMP in various tissues of rats with high accuracy. |
