Inhibitory effects of (4-alkoxy-2, 3, 6-trimethylphenyl) glycopyranosides on histamine release induced by antigen-antibody reaction.
The inhibitory effects of newly synthesized 4-alkoxy-2, 3, 6-trimethylphenyl D-glycopyranosides on histamine release induced by antigen-antibody reaction were examined. Among the compounds tested, 4-hexoxy-2, 3, 6-trimethylphenyl alpha-D-mannopyranoside exhibited the strongest inhibitory effect. Furthermore, 4-hexoxy-2, 3, 6-trimethylphenyl alpha-D-glucopyranoside and alpha-D-galactopyranoside markedly inhibited antigen-induced histamine release, and their activities were more potent than those of the corresponding beta-anomers. These results suggest that these compounds may possess excellent anti-allergic activities.
