Bistratamides M and N, Oxazole-Thiazole Containing Cyclic Hexapeptides Isolated from Lissoclinum bistratum Interaction of Zinc (II) with Bistratamide K
(Multidisciplinary Dixital Publishing Institute, 2017-07-01)
[Abstract] Two novel oxazole-thiazole containing cyclic hexapeptides, bistratamides M (1) and N (2) have been isolated from the marine ascidian Lissoclinum bistratum (L. bistratum) collected in Raja Ampat (Papua Bar, ...
Synthesis of Acetylhomoagmatine
(Molecular Diversity Preservation International, 2006)
The first total synthesis of acetylhomoagmatine, a natural product isolated form the methanolic extracts from the sponge Cliona celata, is performed in four steps in a very high yield.
Dolabelladienols A–C, New Diterpenes Isolated from Brazilian Brown Alga Dictyota pfaffii
(Multidisciplinary Digital Publishing Institute, 2014)
[Abstract:]The marine brown alga Dictyota pfaffii from Atol das Rocas, in Northeast Brazil is a rich source of dolabellane diterpene, which has the potential to be used in future antiviral drugs by inhibiting reverse ...
Natural Products from Antarctic Colonial Ascidians of the Genera Aplidium and Synoicum: Variability and Defensive Role
Ascidians have developed multiple defensive strategies mostly related to physical, nutritional or chemical properties of the tunic. One of such is chemical defense based on secondary metabolites. We analyzed a series of ...
Cytotoxic furanoditerpenes from the sponge Spongia tubulifera collected in the Mexican Caribbean
[Abstract] Two new spongian furanoditerpenes, 3β-hydroxyspongia-13(16),14-dien-2-one (1) and 19-dehydroxy-spongian diterpene 17 (2), along with five known terpenes, the spongian furanoditerpenes 9-nor-3-hydroxyspongia-3, ...
Marine natural products from the Yucatan peninsula
(MDPI AG, 2020-01-16)
[Abstract]: Mexico is one of the three areas of the world with the greatest terrestrial and cultural biological diversity. The diversity of Mexican medicinal flora has been studied for a long time and several bioactive ...
Anti-inflammatory effects of 5α,8α-epidioxycholest-6-en-3β-ol, a steroidal endoperoxide isolated from "Aplysia depilans", based on bioguided fractionation and NMR analysis
[Abstract:] Sea hares of "Aplysia" genus are recognized as a source of a diverse range of metabolites. 5α,8α-Endoperoxides belong to a group of oxidized sterols commonly found in marine organisms and display several ...
In vitro and in vivo assessment of the efficacy of bromoageliferin, an alkaloid isolated from the sponge "Agelas dilatata", against "Pseudomonas aeruginosa"
[Abstract] The pyrrole-imidazoles, a group of alkaloids commonly found in marine sponges belonging to the genus Agelas, display a wide range of biological activities. Herein, we report the first chemical study of the ...
Relative Configuration of Micrograms of Natural Compounds Using Proton Residual Chemical Shift Anisotropy
[Abstract] 3D molecular structure determination is a challenge for organic compounds or natural products available in minute amounts. Proton/proton and proton/carbon correlations yield the constitution. J couplings and ...
Antiviral and Antiproliferative Potential of Marine Organisms from the Yucatan Peninsula, Mexico
[Abstract] Viral infections are one of the main human health problems in recent decades and the cancer remains one of the most lethal diseases worldwide. The development of new antiviral drugs for the treatment of human ...
