Glutoxim ® renders immunomodulating, gemostimulating, detoxifying, hepatoprotective action, suppresses drug resistance of tumor cells to antibiotics of anthracycline series, alkylating agents; allows to overcome drug resistance Mycobacterium tuberculosis to isoniazid, associated with genes katG (the catalase peroxidase gene) and inhA (enol-APB-reductase gene).
Glutoxim ® potentiates the action of doxorubicin on tumor cells, chemotherapy agents (isoniazid, rifampicin, rifabutin, cycloserine, capreomycin, levofloxacin, cationic antimicrobial peptide of catalatezin) on Mycobacterium tuberculosis.
The immunomodulatory effect of Glutoxim® is due to a receptor-mediated effect on calcium dependent macrophage signaling pathways, which leads to an increase in:
- Survival and functional capacity of tissue macrophages;
- exocytosis of sub-membrane granules with intracellularly parasitic forms Mycobacterium tuberculosis;
- activity of lysosomal enzymes;
- formation of reactive oxygen species;
- absorption and death of microorganisms;
- secretion of cytokines: interleukin 1, interleukin 6, tumor necrosis factor, interferons, erythropoietin, interleukin 2; cationic antimicrobial peptides - Defensins, catalecidins.
The gemostimulating effect of Glutoxim® is due to the receptor-mediated enhancement of bone marrow hematopoiesis: the processes of erythropoiesis, lymphopoiesis and granulocytomonocytopoiesis. The effect on the progenitor cells of different lines of blood cells is mediated by the functioning of MAP and inositol kinase systems, leads to an increase in the stability of differentiating hematopoietic cells, restores their sensitivity to the action of endogenous factors of hemopoiesis.
Detoxification and hepatoprotective effects of the drug are due to the receptor-mediated enhancement of the expression of second-phase enzymes of xenobiotic detoxification, including glutathione reductase, glutathione peroxidase, glutathione-S-transferase, glucose-6-phosphate dehydrogenase, hemoxygenase-1, increased intracellular level of reduced glutathione, from the toxic effects of radicals.
Glutoxim® has a direct inhibitory effect on the activity of the multidrug resistance factor of tumor cells - the P-glycoprotein protein (Pgp), which determines the stability of tumor cells to the action of chemotherapy, including anthracycline antibiotics, preparations of alkylating action.
Glutoxim ® initiates the isoniazid transformation reaction - a prodrug, into a pharmacologically active form - isonicotinic acid, having a bacteriostatic effect on Mycobacterium tuberculosis, that allows to overcome drug resistance Mycobacterium tuberculosis, caused by negative transformation of genes katG (the catalase peroxidase gene) and inhA (enol-APB-reductase gene).
Glutoxim ® stimulates the processes of exocytosis of vesicles from macrophages with intracellularly parasitizing microorganisms, including Mycobacterium tuberculosis, ensuring their removal from the pharmacological shelter and making antibacterial drugs available for action, including isoniazid, rifampicin, rifabutin, cycloserine, capreomycin, levofloxacin.
Glutoxim ® enhances the secretion of cationic peptides - defensins and catalacidins by macrophages, stimulates their absorption by mycobacteria of tuberculosis, determining the mediated antibacterial action of the drug.
