Abstract

Three new acylhomoserine lactone (AHL) inhibitors have been isolated from the Korean red alga.Ahnfeltiopsis flabelliformis, via bioactivity-guided fractionation using the recombinantAgrobacterium tumefaciens liquid culture bioassay. Unlike the majority of AHL inhibitors reported to date, these compounds were α-d-galactopyranosyl-(1→2)-glycerol (floridoside) (1), betonicine (2), and isethionic acid (3), all of which are structurally unrelated to AHLs.
