摘要

A 13-C labeled water soluble derivative of alkylcatechol was synthesized and reacted with human serum albumin in phosphate buffer at pH 7.4 in air to allow a slow oxidation of the catechol into orthoquinone. The formation of several adducts was evidenced by a combination of 13C and 1H 13C correlation NMR. Although some adducts could result from a classical o-quinone formation—Michael type addition, our results suggest that a ...
