Common NameDextramycin
DescriptionTyfomycine, also known as levoplast or levosin, belongs to the class of organic compounds known as nitrobenzenes. Nitrobenzenes are compounds containing a nitrobenzene moiety, which consists of a benzene ring with a carbon bearing a nitro group. Tyfomycine is an extremely weak basic (essentially neutral) compound (based on its pKa). High-level resistance is conferred by the cat-gene; this gene codes for an enzyme called chloramphenicol acetyltransferase, which inactivates chloramphenicol by covalently linking one or two acetyl groups, derived from acetyl-S-coenzyme A, to the hydroxyl groups on the chloramphenicol molecule. This compound has been identified in human blood as reported by (PMID: 31557052 ). Dextramycin is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Dextramycin is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
