Structure elucidation and NMR assignments of two unusual monoterpene indole alkaloids from Psychotria stachyoides.
Summary of "Structure elucidation and NMR assignments of two unusual monoterpene indole alkaloids from Psychotria stachyoides."
Two unusual monoterpene indole alkaloids, stachyoside (1) and nor-methyl-23-oxo-correantoside (2), have been isolated from the aerial parts of Psychotria stachyoides. The structural elucidation of both compounds was performed by the aid of HRESIMS, FT-IR, and 1D- and 2D-NMR techniques including COSY, HSQC, HMBC, and NOESY.

Medical and Biotech [MESH] Definitions
Carbazoles
Benzo-indoles similar to CARBOLINES which are pyrido-indoles. In plants, carbazoles are derived from indole and form some of the INDOLE ALKALOIDS.
Indole Alkaloids
Group of alkaloids containing a benzylpyrrole group (derived from TRYPTOPHAN)
Vinca Alkaloids
A group of indole-indoline dimers which are ALKALOIDS obtained from the VINCA genus of plants. They inhibit polymerization of TUBULIN into MICROTUBULES thus blocking spindle formation and arresting cells in METAPHASE. They are some of the most useful ANTINEOPLASTIC AGENTS.
Securidaca
A plant genus of the family POLYGALACEAE that contains securiosides and indole alkaloids.
Psychotria
A plant genus of the family RUBIACEAE. Members contain psychotridine and brachycerine (indole alkaloids).
