Furaltadone (AMOZ)

Furaltadone is a nitrofuran antibiotic that is effective against bacterial infections in birds when added to feed or drinking water. Furaltadone is an oxazolidinone that is 1,3-oxazolidin-2-one substituted at position 1 by a (5-nitro-2-furyl)methylene]amino group and at position 5 by a morpholin-4-ylmethyl group. An antibacterial formerly used oraly but withdrawn due to toxicity, it is used topically (as the hydrochloride salt) for treatment of ear disorders. It has a role as an antibacterial drug. It is a C-nitro compound, a member of furans, a member of morpholines and an oxazolidinone. A competitive time-resolved fluoroimmunoassay (TRFIA) using a biotin–streptavidin system was developed for the detection and quantification of the furaltadone metabolite 3-amino-5-morpholinomethyl-2-oxazolidinone (AMOZ) in aquatic tissues. AMOZ-bovine serum albumin was coated to a solid phase and then competed with a free nitrophenyl derivative of AMOZ (2-NP-AMOZ) in standards or samples for binding with biotin-anti-AMOZ-ovalbumin polyantibody.
