Iron(III) Monoglycerolate: A Potential Hemostatic Agent for Topical Application

Background: Glycerolates of biogenic elements are of interest because of their pharmacological activity. Some of them are used as active substances in agents for topical application and as biocompatible precursors in sol-gel synthesis of bioactive materials. Objective: In this work, morphostructural feature, ability to hydrolyze, and the pharmacological activity of previously synthesized iron(III) monoglycerate were studied. Methods: Analytical techniques, including SEM, TEM, XRD, TGA, IR spectroscopy, DLS and ELS, were used. Hemostatic activity was studied in vivo, and primary toxicological studies were carried out on experimental animals. Antimicrobial activity was studied using the agar diffusion method. Results: When dispersed in glycerol, solid crystalline iron(III) monoglycerolate transforms into an amorphous state, forming aggregates with an average particle size of 250 nm (according to DLS data). It slowly hydrolyzes in water at room temperature, while hydrolysis does not take place in an aqueous glycerol media. Iron(III) monoglycerolate is nontoxic and exhibits pronounced hemostatic activity and low antibacterial activity (relative to the strain S. аureus). Conclusion: Iron(III) monoglycerolate can be considered a potential hemostatic agent, showing promise for topical application in medical and veterinary practice, as well as a novel biocompatible precursor in the sol-gel synthesis of practically useful substances.
