(+/-)-Gelliusines A and B, two diastereomeric brominated tris-indole alkaloids from a deep water New Caledonian marine sponge (Gellius or Orina sp.) [PDF]

open access: yes, 1994
Two new diastereomeric brominated tris-indole alkaloids occurring as enantiomeric pairs, (±)-gelliusine A (I) and its isomer (±)-gelliusine B, have been isolated from a deep water New Caledonian sponge (Gellius or Orina sp.), whose crude ext.

Analysis of alkaloids (indole alkaloids, isoquinoline alkaloids, tropane alkaloids)

open access: yes, 2020
Alkaloids are a large cluster of molecules found in Mother Nature all over the world. They are all secondary compounds and collection of miscellaneous elements and biomolecules, derived from amino acids or from transamination. This diverse chemical group is categorized, based on the amino acids that deliver their nitrogen atom and part of their ...

Indole Alkaloids of Ailanthus altissima

open access: yesJournal of Natural Products, 1984
Ailanthus altissima (Mill.) Swingle, Syn. A. glandulosa Desf. (Simaroubaceae), is a large tree indigenous to China. It is known as the “Tree of Heaven” and has been the subject of several chemical studies. The presence of quassinoid-type bitter principles (1-6), flavonols (7,8), and 2,6-dimethoxy-p-benzoquinone (9,10) has been reported in earlier ...
