| Research Abstract |
In Asia-Pacific food web, we found that natural organobromine compounds are produced by some specific species of marine algae and sponges. We developed the LC/MS/MS method for screening of dihydroxy-PBDEs in sponges from Palau. In thorny oyster from the Philippines, naturally produced hydroxy-PBDEs were O-methylated with growth to the corresponding methoxy-PBDEs. In bivalves from Vietnam, halogenated biphenols(i. e. Br_3Cl-and Br_2Cl_2-analogs) that show antibacterial activities, were isolated. These secondary metabolites are accumulated in the higher organisms via food chain and also anticipated as lead compounds for bioactive medicines.
