SYNTHESES OF NEW IMMUNOSUPPRESSIVE MYRIOCIN ANALOGS, 2-EPI-MYRIOCIN, 14-DEOXOMYRIOCIN, Z-14-DEOXOMYRIOCIN, AND NOR-DEOXOMYRIOCINS : THEIR STRUCTURE-ACTIVITY RELATIONSHIPS

Abstract

Eight new myriocin analogs, 2-epi-myriocin, Z-14-deoxomyriocin, and nor-deoxomyriocins, and a known myriocin derivative, 14-deoxomyriocin, were synthesized from 2-deoxy-D-glucose via common intermediates in previous myriocin and Z-myriocin syntheses. The immunosuppressive activities of new myriocin analogs and Z-myriocin on mouse allogeneic mixed lymphocyte reaction were examined, and, by comparing with those of myriocin and 14-deoxomyriocin, some structure-activity relationships have been found.
