Method for obtaining supramolecular complex based on 3-ohypyridine derivatives and its application for correction of osteoporosis
Abstract
Introduction: Currently, there are no safe and ideal medicines for the prevention and treatment of oophorectomy-induced osteoporosis. The development of an effective pharmacotherapy for hypoestrogen-induced osteoporosis is an important task of pharmacology. Materials and Methods: A new supramolecular complex (composition №1) was obtained on the basis of 3-hydroxypyridine derivatives: 2-ethyl-6-methyl-3-hydroxypyridinium 3-pyridinocarbonoate and 2-ethyl-6-methyl-3-hydroxypyridinium N-acetyl-6-aminohexanoate in a ratio of 1:3 by topochemical synthesis. The study of the osteoprotective activity of the supramolecular complex at a dose of 50 mg/kg was performed on 60 white female rats of the Wistar line on a model of hypoestrogen-induced osteoporosis. The effectiveness of the osteoprotective activity of the complex was evaluated on the 57th day of the experiment. Results and Discussion: The new supramolecular complex (composition №1) has osteoprotective activity, which is expressed in improving the indicators of X-ray and histomorphological samples. Oral administration of composition №1 at a dose of 50 mg/kg led to an increase in bone density to values of 2.55±0.02 g/cm3, which is 1.3 times higher than in the control group 1.92±0.01 g/cm3 (p≤0.05) and reduce bone resorption by improving cortical and trabecular bone structures. Conclusion: The obtained data characterize the prospects of studying composition №1 for the correction and prevention of hypoestrogen-induced osteoporosis.
