A new C15-acetogenin, sagonenyne (20), exhibiting an unusual single tetrahydropyran ring was isolated from an ethyl acetate extract of Laurencia obtusa collected on the Corsican coastline. Its structure was established by detailed NMR spectroscopic analysis, mass spectrometry, and comparison with literature data. Twenty-three known compounds were identified in the same extract by means of colum...
Clumps of highly-branched red algae Laurencia spp. serve as important settling habitat for postlarval spiny lobsters Panulvus argus and as residence for early benthic-stage juveniles. G ~ v e n choice between the 2 most abundant macrophytes in Florida Bay, Laurenna spp. and the seagrass Thalassia testudinum, postlarval and juvenile lobsters chose Laurencia spp. Postlarvae apparently use intrica...
Neorogioltriol is a tricyclic brominated diterpenoid isolated from the organic extract of the red algae Laurencia glandulifera. In the present study, the anti-inflammatory effects of neorogioltriol were evaluated both in vivo using carrageenan-induced paw edema and in vitro on lipopolysaccharide (LPS)-treated Raw264.7 macrophages. The in vivo study demonstrated that the administration of 1 mg/k...
جنس laurencia از راسته ceramiales، خانواده rhodomelaceae و شاخه جلبک های قرمز می باشد که برای اولین بار در سال 1813 توسط lamouroux و تنها با هشت گونه شناسایی و معرفی شد. از این جنس امروزه 170 گونه گزارش شده است که اکثر اعضای آن در خطوط ساحلی مناطق حاره مثل جنوب ایران یافت می شوند. بسیاری از این گونه ها دارای مورفولوژی متغیری هستند که تنها از طریق ویژگی-های تولیدمثلی و تفاوت های آناتومی جزئی متم...
The red seaweed Laurencia dendroidea belongs to the Rhodophyta, a phylum of eukaryotic algae that is widely distributed across the oceans and that constitute an important source of bioactive specialized metabolites. Laurencia species have been studied since 1950 and were found to contain a plethora of specialized metabolites, mainly halogenated sesquiterpenes, diterpenes and triterpenes that po...
Marine red algae (Rhodophyta) are a rich source of bioactive halogenated natural products. The biogenesis of the cyclic halogenated terpene marine natural products, in particular, has attracted sustained interest in part because terpenes are the biogenic precursors of many bioactive metabolites. The first enzymatic asymmetric bromination and cyclization of a terpene, producing marine natural pr...
