title: IC202A, a new siderophore with immunosuppressive activity produced by Streptoalloteichus sp. 1454-19. I. Taxonomy, fermentation, isolation and biological activity.
abstract: IC202A, a new immunosuppressive compound, was isolated from the culture filtrate of Streptoalloteichus sp. 1454-19. It showed a suppressive effect on mixed lymphocyte culture reaction with an IC50 value of 3.6 microg/ml and mitogen induced lymphocyte blastogenesis in vitro.
