ALPHA-APO-OXYTETRACYCLINE Chemical Properties,Usage,Production

Description

β-Apooxytetracycline is a potential impurity found in commercial preparations of oxytetracycline. β-Apooxytetracycline is a degradation product formed from oxytetracycline via acid hydrolysis. It has a relative potency of 0.1 compared with oxytetracycline for inhibiting the growth of aerobic sludge bacteria, an MIC50 value of 32 mg/L for tetracycline-sensitive strains of Pseudomonas, and MIC50 values of greater than 32 mg/L for tetracycline-sensitive strains of Agrobacterium, Moraxella, and Bacillus, as well as tetracycline-resistant strains of E. coli. β-Apooxytetracycline (10 mg/kg) is toxic to rats, decreasing body weight, disrupting blood cell counts, and inducing hepatocyte necrosis.

Chemical Properties

yellow-brown to brown powder

Uses

Oxytetracycline metabolite (absolute stereochemistry unknown)

Uses

β-Apooxytetracycline is a degradation product of oxytetracycline formed under acidic conditions. An initial dehydration to anhydrooxytetracycline then undergoes an internal cyclisation of the C5-OH to the C12 ketone. The resulting cleavage of the C12-C12a bond generates two isomers, α- and β-apooxytetracycline. β-apooxytetracycline is an important standard for monitoring oxytetracycline stability.
