New cysteine-containing derivatives of glycyrrhizic acid were synthesized by its coupling with Cys(Bzl) esters or the Cys(Bzl)-Val-OBu(t) dipeptide by the active ester method (DCC/HOSu) or by Woodward's reagent K. The derivatives with Cys(Bzl) and Cys(Bzl)-Val residues attached to the carbohydrate part of the molecule stimulated the primary immune response and the reaction of delayed-type hypersensitivity
通过活性酯法(DCC / HOSu)或伍德沃德试剂K,将其与Cys(Bzl)酯或Cys(Bzl)-Val-OBu(t)二肽偶联,合成了新的含半胱氨酸的甘草次酸衍生物。 Cys(Bzl)和Cys(Bzl)-Val残基附着在分子碳水化合物部分上的衍生物以2 mg / kg的剂量刺激小鼠的初次免疫反应和迟发型超敏反应。该论文的英文版:Russian Journal of Bioorganic Chemistry,2004年,第1卷。30号 1; 另请参见http://www.maik.ru。
