Assay for determining oxazolidinone antibiotics having minimum monoamine oxidase inhibitory activity

摘要

Anti-microbial oxazolidinone antibiotics are provided having formula I and formula II wherein R1 is methyl, ethyl, cyclopropyl, or dichloromethyl; R2 and R3 are independently hydrogen or fluoro; R4 is ethyl or dichloromethyl.The oxazolidinone antibiotics have minimum inhibitory activity for monoamine oxidase. An assay for detecting such oxazolidinone antibiotics is carried out by incubating a potential oxazolidinone inhibitor with a monoamine oxidase, then adding 1-methyl-4-(1-methyl-2-pyrryl)-1,2,3,6-tetrahydropyridine and determining inhibitory activity of the antibiotic.
