Synthesis, properties, and antianemic activity of new metal complexes of sodium pectinate with iron and calcium

Аннотация

A new water-soluble complex based on sodium pectinate with iron and calcium (P-NaFeCa) was synthesized. The regularities of the complexation of sodium pectinate (with a 35% content of COONa groups) with biogenic metals Ca and Fe were studied. The content of macro- and microelements was determined by atomic emission spectrometry; the product was identified by IR spectroscopy. Using atomic force microscopy, it was found that the average particle size of P-NaFeCa is ~170 nm. The efficiency of P-NaFeCa (per os) was studied for the first time in animals with hemolytic anemia modeled by administration of phenylhydrazine. It was experimentally shown that in vivo P-NaCaFe at a dose of 60 mg kg^–1 containing 50% of the recommended therapeutic dose of iron helps to recover the number of erythrocytes and mean concentration hemoglobin in erythrocyte, which indicates the efficiency of P-NaCaFe as an agent restoring the blood parameters after exposure to hemolytic poisons.
