Sesquiterpenes from Laurencia similis.
One new sesquiterpene, (4E)-1-bromo-5-[(1'S*,3'R*)-3'-bromo-2',2'-dimethyl-6'-methylenecyclohexyl]-3-methylpent-4-ene-2,3-diol (1), and fifteen known sesquiterpenes, isopalisol (2), luzonensol (3), palisadin B (4), aplysistatin (5), palisadin A (6), 4-hydroxyl-palisudin C (7), 5-acetoxypalisadin B (8), 10-hydroxyaristolan-9-one (9), aristol-8-en-1-one (10), aristolan-9-en-1-one (11), aristolan-...
متن کاملCytotoxic compounds from Laurencia pacifica
BACKGROUND The current investigation sought to explore the nature of the secondary metabolites in the algae, Laurencia pacifica. RESULTS This report details the first isolation of the sesquiterpenes isoaplysin (1), isolaurenisol (2), debromoisolaurinterol (3), debromoaplysinol (4), laur-11-en-10-ol (5), 10α-hydroxyldebromoepiaplysin (6), and the previously unknown 10-bromo-3,7,11,11-tetrameth...
متن کاملIn Vivo and in Vitro Anti-Inflammatory Activity of Neorogioltriol, a New Diterpene Extracted from the Red Algae Laurencia glandulifera
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...
متن کاملFormation of highly oxygenated organic molecules from aromatic compounds
Anthropogenic volatile organic compounds (AVOC) often dominate the urban atmosphere and consist to a large degree of aromatic hydrocarbons (ArHC), such as benzene, toluene, xylenes, and trimethylbenzenes, e.g. from handling and combustion of fuels. These compounds are important precursors for the formation of secondary organic aerosol. Here we show that oxidation of aromatics with OH leads to a...
متن کاملEjection of neutral molecules from ion-bombarded organic surfaces.
Time-of-flight distributions of neutral molecules ejected from various organic surfaces have been measured subsequent to 8 keV Ar+ and H2+ ion bombardment. The distributions show that depending on the physical and chemical nature of the substrate, the neutral molecules have strikingly different desorption profiles. For C6H6/Ag¿111¿, at low coverage the C6H6 molecules eject with energies in the ...
