When Is an Indole Not an Indole? [PDF]
An indole is not an indole when it is a naphthalene derivative! We routinely measure 5-hydroxyindoleacetic acid (5HIAA) by a long-established method using nitrosonaphthol, as first described by Udenfriend in 1955 (1), but with various modifications to improve specificity (2).

Synthesis of Bis(3‐indolyl)methanes Mediated by Potassium tert‐Butoxide
The indole moiety is an important N‐heterocycle found in natural products, and a key structural component of many value‐added chemicals including pharmaceuticals. In particular, bis(3‐indolyl)methanes (BIMs) are an important subgroup of indoles, composed

The Emergence of Insect Odorant Receptor-Based Biosensors
The olfactory receptor neurons of insects and vertebrates are gated by odorant receptor (OR) proteins of which several members have been shown to exhibit remarkable sensitivity and selectivity towards volatile organic compounds of significant importance ...

Marine indole alkaloids comprise a large and steadily growing group of secondary metabolites. Their diverse biological activities make many compounds of this class attractive starting points for pharmaceutical development. Several marine-derived indoles were found to possess cytotoxic, antineoplastic, antibacterial and antimicrobial activities, in ...

New Approaches to Indoles and Indole Alkaloids [PDF]
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

α-Glucosidase Inhibitors Based on Oleanolic Acid for the Treatment of Immunometabolic Disorders
Using oleanolic acid as a starting compound, a series of new oleanane-type triterpenic derivatives were synthesized via O-acylation (with nicotinic, isonicotinic, and methoxycinnamic acid acyl chlorides), N-amidation (with cyclic- or polyamines), the ...
