Biological Activity

Description Oxytetracycline(Terramycin) is a broad-spectrum tetracycline antibiotic, used to treat infections with bacteria.
In vivo

Oxytetracycline (200 mg/kg for 15 days) results a significant elevation in serum hepatospecific markers such as aspartate transaminase, alanine transaminase, alkaline phosphatase, lactate dehydrogenase, and bilirubin and the levels of lipid peroxidation markers (thiobarbituric acid reactive substances (TBARS) and lipid hydroperoxides) in rat liver. Oxytetracycline also causes a significant reduction in the activities of superoxide dismutase, catalase, glutathione peroxidase, reduced glutathione (GSH), vitamin C and vitamin E in rat liver. Oxytetracycline (200 mg/kg) combined with Naringenin (50 mg/kg b.w.t.) significantly decreases the activities of serum aspartate transaminase, alanine transaminase, alkaline phosphatase, lactate dehydrogenase and the levels of bilirubin along with significant decrease in the levels of lipid peroxidation markers in the rat liver. [1] Oxytetracycline (200 mg/kg, oral for 15 days) produces hepatic damage as manifested by a significant increase in serum hepatic markers namely aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), bilirubin and increases plasma and hepatic lipid peroxidation indices (TBARS and hydroperoxide) in rats. Oxytetracycline significantly decreases the levels of enzymatic antioxidants namely superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx). [2]

Customer Product Validation

Effect of FDA approved drugs on EBOV transfected donor and recipient immune cells. (A) Varying concentrations of Cambinol and Esomepraole (1 nM, 1 μM, 10 μM), Oxytetracycline (1 nM, 10 nM, 10 μM), and DMSO (0.00001, 0.0001, 0.001%) treatments were administered to VP40-transfected 293T cells, followed by incubation for 3 days. Supernatant was centrifuged to remove cellular material and subsequently incubated for 72 h at 4°C with 20 μL of 30% slurry of NT80/82 beads. The NT pellet was washed twice with PBS and resuspended in SDS Laemmli buffer, followed by Western blot analysis for levels of exosomal markers CD63 and Alix. Actin levels were also analyzed. Mid-log phase EVTR2C cells (containing VP40) were treated with either low (0.1 μM), medium (1 μM), or high (10 μM) concentrations of Oxytetracycline and incubated for 5 days along with untreated 293T cells. Cell-free supernatants were harvested, filtered, and used to treat CEM (B), Jurkat (C), and U937 (D) cells. Cells were incubated for 5 days and assayed with CellTiter-Glo for viability. Statistical significance was determined using two-tailed student’s t-test with all groups compared to the untreated 293T cell control groups.
