Nine myriocin analogs, 2-epi-myriocin, 14-deoxomyriocin, Z-14-deoxomyriocin, and nor-deoxomyriocins, were synthesized from 2-deoxy-D-glucose via common intermediates used in previous myriocin and Z-myriocin syntheses. Immunosuppressive activites of those myriocin analogs on mouse allogeneic mixed lymphocyte reaction were examined, and Z-14-deoxomyriocin was found to show the most potent activity among them. The structure-activity relationships are discussed.
通过先前合成沙生腊壳菌素(myriocin)和Z-myriocin过程中使用的共同中间体,合成了9种沙生腊壳菌素类似物:2-表-沙生腊壳菌素、14-去氧沙生腊壳菌素、Z-14-去氧沙生腊壳菌素和去甲去氧沙生腊壳菌素。检测了这些沙生腊壳菌素类似物对小鼠异
基因混合淋巴细胞反应的免疫抑制活性,发现Z-14-去氧沙生腊壳菌素在其中表现出最强的活性。并讨论了结构-活性关系。
