Microbial Hydroxylation of Indole Alkaloids [PDF]

open access: yesApplied Microbiology, 1964
The hydroxylation of the indole-type alkaloids, yohimbine, α-yohimbine, β-yohimbine, and corynanthine, was achieved with several genera of higher fungi and species of Streptomyces . Microorganisms were found which monohydroxylated these compounds in three different positions.

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 ...

New Approaches to Indoles and Indole Alkaloids [PDF]

open access: yesProceedings of the 14th Brazilian Meeting on Organic Synthesis Proceedings, 2013
Second only to pyridines, indoles are among the most common aromatic scaffolds present in bioactive molecules. The 5-hydroxy indole moiety alone has currently >10,500 substructure hits Among the many indole-containing alkaloid scaffolds, ergot alkaloids comprise a notable group of natural products of great biological activities. The striking biological

Studies on indole alkaloids [PDF]

open access: yes, 1936
Among different types of alkaloids the structure of those derived from indole is least known. The constitution of only very few members of this group is fixed, and in most cases it remains obscure.#1. On the Alkaloids of Calycanthus floridus L.
