Two tris-indole alkaloids, (+/-) gelliusines A and B [1], have been isolated for the first time from a marine source, the New Caledonian sponge, Orina sp. (or Gellius sp.), along with five further indole constituents [2-6]. Compound 6 has been identified as 2,2-bis-(6'-bromo-3'-indolyl(-ethylamine, previously isolated from the tunicate Didemnum candidum, but the remaining four indoles [2-5] are novel compounds. These showed anti-serotonin activity and a strong affinity for somatostatin and… Expand
Araiosamines A-D: tris-bromoindole cyclic guanidine alkaloids from the marine sponge Clathria (Thalysias) araiosa.
Four new tris-bromoindole cyclic guanidine alkaloids were isolated from the methanol extract of a marine sponge, Clathria (Thalysias) araiosa, collected from Vanuatu, delineate a new class of indole alkaloid apparently derived from a linear polymerization process involving a carbon-carbon bond formation.

Dragmacidin F: A New Antiviral Bromoindole Alkaloid from the Mediterranean Sponge Halicortex sp.
Abstract A new bromoindole alkaloid, named dragmacidin F ( 1 ) and structurally related to other dragmacidins previously described, was isolated from a marine sponge of the genus Halicortex collectedExpand
Antiviral enantiomers of a bisindole alkaloid with a new carbon skeleton from the roots of Isatis indigotica
A pair of indole alkaloid enantiomers with a novel bisindolylacetamide skeleton, insatindibisindolamides A and B (1a and 1b), was isolated from an aqueous extract of Isatis indigotica roots. TheExpand
New Antimalarial and Antimicrobial Tryptamine Derivatives from the Marine Sponge Fascaplysinopsis reticulata
Three new tryptophan derived alkaloids are highlighted and the known 8-oxo-tryptamine and the mixture of the (E)-6-bromo-2′-demethyl-3′-N-methylaplysinopsin (6) and (Z) showed moderate antiplasmodial activity against Plasmodium falciparum. Expand
Chlorinated bis-indole alkaloids from deep-sea derived Streptomyces sp. SCSIO 11791 with antibacterial and cytotoxic activities
Two new chlorinated bis-indole alkaloids, dionemycin (1) and 6-OMe-7′,7″-dichorochromopyrrolic acid (2), along with seven known analogs 3–9, were isolated from the deep-sea derived Streptomyces sp.Expand
Alkaloids from the root of Isatis indigotica.
Seventeen new alkaloids and 14 known analogues have been isolated from an aqueous extract of the root of Isatis indigotica by extensive spectroscopic data analysis, including 2D NMR, single-crystal X-ray crystallography using anomalous scattering of Cu Kα radiation, and electronic circular dichroism spectra calculations based on the quantum-mechanical time-dependent density functional theory.
