Oxytetracycline 是一种四环素类抗生素。它强力抑制革兰氏阴性和革兰氏阳性细菌。它是一种蛋白质合成抑制剂，可阻止 aminoacil-tRNA 与复杂的核糖体 RNA 结合，具有抗HSV-1的活性。

Oxytetracycline is a TETRACYCLINE analog isolated from the actinomycete STREPTOMYCES rimosus and used in a wide variety of clinical conditions.

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]
