A PAF antagonist, designated as FR-900452, was isolated from fermentation products of Streptomyces phaeofaciens and the molecular formula was determined as C22H25N3O3S. The compound inhibited PAF-induced rabbit platelet aggregation with an IC50 of 3.7 X 10(-7)M, but was much less active against collagen-, arachidonic acid- or ADP-induced aggregation (IC50; 6.4 X 10(-5), greater than 10(-4) or greater than 10(-4)M, respectively).
