摘要

Nitrone spin traps have been employed as probes for the identification of transient radical species in chemical and biological systems using electron paramagnetic resonance (EPR) spectroscopy and have exhibited pharmacological activity against oxidative-stress-mediated diseases. Since superoxide radical anion (O2•−) is a major precursor to most reactive oxygen species and calix [4] pyrroles have been shown to exhibit high affinity to anions, a ...
