生物活性

Oxytetracycline is an antibiotic belonging to the tetracycline class. Oxytetracycline potent inhibits Gram-negative and Gram-positive bacteria. Oxytetracycline is a protein synthesis inhibitor and prevents the binding from aminoacil-tRNA to the complex m-ribosomal RNA. Oxytetracycline also possesses anti-HSV-1 activity.

体外研究(In Vitro)

Oxytetracycline is an important member of the bacterial aromatic polyketide family, which is a structurally diverse class of natural products. Oxytetracycline is synthesized by a type II polyketide synthase that generates the poly-beta-ketone backbone through successive decarboxylative condensation of malonyl-CoA extender units, followed by modifications by cyclases, oxygenases, transferases, and additional tailoring enzymes.

Medlife has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究(In Vivo)

The effects of administration a therapeutic dose of Oxytetracycline (82.8 mg/kg of bw to 1 % bw/day) for 10 days are species specific. Oxytetracycline increases the relative liver weight in Morone chrysops x M. saxatilis, the enzymatic activity of CYP3A4 in Ictalurus punctatus, protein expression of CYP3A4 in Oreochromis niloticus and depleted the hepatic CYP3A4 in the latter.
For Oxytetracycline, the limits are 100 μg/kg in muscle and milk, 200 μg/kg in egg, 300 μg/kg in liver and 600 μg/kg in kidney. Oxytetracycline (OTC) is administered to fish as medicated feed at concentrations ranging from 35 to 75 mg a.i kg-1 biomass day-1 for 7-14 days.
