Reported Study

The paper researches the effect of cobalt (АСCo2+) and zinc (АСZn2+), nickel (Ni2+) and manganese (Mn2+) acetylsalicylates in doses of 5 and 10 mg/kg on the characteristics of the rats’ cardiorespiratory system. The study was carried out on the basis of the Center for collective use of scientific equipment «Experimental Physiology and Biophysics» of the Department of Human and Animal Physiology and Biophysics of the V. I. Vernadsky Crimean Federal University. The research of the biological effect of the acetylsalicylic acid, АСCo2+, АСZn2+ , АСNi2+, АСMn2+was carried out during their intraperitoneal injection into rats in doses of 5 mg/kg and 10 mg/kg. Simultaneously the following characteristics of all the groups’ animals were registered: heart rate (HR), respiratory rate (RR), systolic blood pressure (SBP) and diastolic blood pressure (DBP). The pulse pressure (PP) was calculated on the basis of the SBP and DBP indices difference. BP, HR and RR of the rats were registered with the help of the system NIBP200A («BiopacSystems, Inc.», USA). The results of the current research allowed to determine that the coordinating compounds of the acetylsalicylic acid with such metals as Co, Zn, Ni2+, Mn2+ not only have more pronounced biological effect in comparison with the acetylsalicylic acid, but demonstrate new properties; the most effect on the cardiorespiratory system was achieved by АСZn2+. Thus, the results of the current research allow us to claim that the salts of the acetylsalicylates, having the metal-complexing in its molecules’ composition, have more pronounced and qualitatively new properties in comparison with the acetylsalicylic acid precursor’s properties; this makes the further search for biological and pharmaceutical activity of these coordinating compounds more perspective, as well as it makes the technology of complexingan inexpensive and highly efficient approach to the creation of new medicines. The reported study was funded by RFBR, project number 20-33-70142

In this paper the synthesis and the study of some complex compounds of Fe(III) with ligands derived from: 2-(4-chloro-phenylsulfanyl)-1-(2-hydroxy-3,5-diiodo-phenyl)-ethanone (HL1), 1-(3,5-dibromo-2-hydroxy-phenyl)-2-phenylsulfanyl-ethanone(HL2), and 2-(4-chloro-phenylsulfanyl)-1-(3,5-dibromo-2-hydroxy-phenyl)-ethanone (HL3) is presented. The characterization of these complexes is based on method as: the elemental chemical analysis, IR and ESR spectroscopy, M�ssbauer, the thermogravimetric analysis and X-ray diffraction. Study of the IR and chemical analysis has evidenced that the precipitates form are a complexes and the combination ratio of M:L is 1:2. The central atoms of Fe(III) presented paramagnetic properties and a octaedric hybridization. Starting from this precipitation reactions, a method for the gravimetric determination of Fe(III) with this organic ligands has been possible. Based on the experimental data on literature indications, the structural formulae of the complex compounds are assigned.
