One step conversion method of indole-3-carboxaldehydes into indole-3-acetonitriles is developed. Applying the method, 4-nitro- (7 a), 4-phenyl-(7 b), 4-iodo- (7 c), 4-methoxy- (7 d), and 4-benzyloxyindole-3-acetonitrile (7 e) are available in two steps from indole-3-carboxaldehyde (4).

Arvelexin is one of major constituents of Brassica rapa that exerts anti-inflammatory activities. Several indolyl-3-acetonitrile derivatives were synthesized as arvelexin analogs and evaluated for their abilities to inhibit NO and PGE2 productions in LPS-induced RAW 264.7 cells. Of the indolyl-3-acetonitriles synthesized, compound 2k, which possesses a hydroxyl group at C-7 position of the indole ring and an N-methyl substituent, more potently inhibited NO and PGE2 productions and was less cytotoxic than arvelexin on macrophage cells.

A facile synthesis of 6-hydroxyindole-3-acetic acid 1a, which is the proposed aromatic subunit of NPTX-1~6, is described. Radical cyclization of isonitrile 2 successfully afforded 9 in high yield. The aromatic subunit of NPTX-1~6 was confirmed as 4-hydroxyindole-3-acetic acid 12 by comparison of the 1H-NMR spectra with those of authentic 4- and 6-hydroxyindole-3-acetic acids.
Characterization and synthesis of a new calcium antagonist from the venom of a fishing spider
McCormick, Kevin D.,Kobayashi, Kazumi,Goldin, Stanley M.,Laxma Reddy,Meinwald, Jerrold
, p. 11155 - 11168 (2007/10/02)
A new calcium antagonist, CNS 2103, is isolated from the venom of a fishing spider, Dolomedes okefinokensis. The structure of this compound is derived from spectroscopic data, including tandem mass spectrometry. A flexible, convergent synthesis of CNS 2103 is described.
