TS-015133 — 5-carbamoyl-5-methyl-1-pyrroline N-oxide (AMPO) as an improved cyclic spin trap, especially in mitigating superoxide radicals.
The linear PBN-type nitrones are limited by their ability to discern different radicals while the cyclic DMPO-type nitrones are limited by the stability of the adducts they form. Enolized DMPO-type spin adducts have been shown to dimerize and produce a six-line electron paramagnetic resonance (EPR…
