Water-soluble β-alanine C₆₀ adducts were synthesized, and the scavenging ability to superoxygen anion radical O₂^-and hydroxyl radicalOH were studied by autoxidation ofpyrogallol and chemiluminescence, respectively. It was found that β-alanine C₆₀ adducts showed an excellent efficiency in eliminating superoxygen anion radical and hydroxyl radical. The 50% inhibition concentration (IC₅₀) for superoxygen anion radical and hydroxyl radical were 0.15 mg/mL and 0.048 mg/mL, respectively. The difference should be mainly attributed to the different scavenging mechanisms.
- alanine C₆₀ adducts,
- superoxygen anion radical O₂^-,
