5-hydroxy-3-vinyl-2(5H)-furanone--a new inhibitor of human synovial phospholipase A2 and platelet aggregation from fermentations of a Calyptella species (basidiomycetes).
5-Hydroxy-3-vinyl-2(5H)-furanone, a potent and selective inhibitor of human synovial phospholipase A2 was isolated from fermentations of a Calyptella species. Its structure as identified by spectroscopic methods is identical to PA 147, an antibiotic previously isolated from a streptomycete. 5-hydroxy-3-vinyl-2(5H)-furanone inhibits the aggregation of human and bovine platelets stimulated by different inducers and exhibits weak antimicrobial activities.
