Dendrimeric-containing nitronyl nitroxides as spin traps for nitric oxide: Synthesis, kinetic, and stability studies

10.1021/ma021292m

The research focuses on the synthesis, kinetic, and stability studies of dendrimeric-containing nitronyl nitroxides as spin traps for nitric oxide (NO?). The purpose of this study was to develop a family of dendrimers that could effectively trap NO?, a free radical with a long lifetime in biological environments, and to overcome the limitations of traditional spin traps, such as iron chelates, which are unstable in biological milieus. The researchers synthesized a series of dendrimers with terminal nitronyl nitroxide groups and evaluated their reaction rates with NO?, their spin-trapping capacity, and their stability under various experimental conditions. The key chemicals used in the synthesis process included 2-(4-carboxyphenyl)-4,4,5,5-tetramethylimidazoline 3-oxide, N-hydroxysuccinimide, 1,3-dicyclohexylcarbodiimide, and various dendrimers like poly(propyleneimine tetraamine) dendrimers (DAB-Am).
