title: Luminaolide, a novel metamorphosis-enhancing macrodiolide for scleractinian coral larvae from crustose coralline algae.
abstract: A new metamorphosis-enhancing macrodiolide, luminaolide (1), was isolated from the crustose coralline algae (CCA) Hydrolithon reinboldii. Its structure was determined by spectroscopic analysis. A fraction (1.30 mug/mL) eluted with 80% aqueous MeOH by ODS gel column chromatography of the same CCA extract induced larval metamorphosis (25.9 +/- 7.4%) against Leptastrea purpurea, and its metamorphosis-inducing activity was further enhanced to 92.6 +/- 2.9% with the addition of 1 (25.6 ng/mL).
