标题 :Multicyclic nitrone spin trapping compositions

摘要:Multicyclic nitrone spin trapping compounds capable of forming stable free radical spin adducts are provided as well as methods for their synthesis. The multicyclic nitrone spin trapping compounds can be reacted with a free radical, such as a hydroxy or hydroperoxy radical, in solution to form a spin adduct which is stable and readily detectable by electron paramagnetic resonance (EPR) spectroscopy. The multicyclic nitrone spin traps can be used to detect free radicals in a sample such as a biological system. In one embodiment, the spin trapping compound, 1,3,3-trimethyl-6-azabicyclo-[3.2.1]oct-6-ene-N-oxide ('TRAZON') is provided, as well as methods for the synthesis of TRAZON and of modified forms of TRAZON. TRAZON can react with a wide range of different free radicals in solution to form free radical spin adducts which are readily detectable by EPR.

摘要:Disclosed are implantable or insertable medical devices that provide resistance to microbial growth on and in the environment of the device and resistance to microbial adhesion and biofilm formation on the device. In particular, the invention discloses implantable or insertable medical devices that comprise at least one biocompatible matrix polymer region, an antimicrobial agent for providing resistance to microbial growth and/or a microbial adhesion/biofilm synthesis inhibitor for inhibiting the attachment of microbes and the synthesis and accumulation of biofilm on the surface of the medical device. Also disclosed are methods of manufacturing such devices under conditions that substantially prevent preferential partitioning of any of said bioactive agents to a surface of the biocompatible matrix polymer and substantially prevent chemical modification of said bioactive agents.
