Usage

Description

LUZINDOLE, also known as a melatonin receptor antagonist, is a member of the indole class, specifically tryptamine with an acetyl group replacing one of the amino hydrogens and a benzyl group replacing the hydrogen at position 2. It is characterized as an off-white amorphous solid and plays a significant role in the modulation of melatonin signaling.

Uses

Used in Pharmaceutical Research:
LUZINDOLE is used as a research compound for studying the roles of melatonin receptor signaling in various pathways, including circadian rhythms, animal behavior, and melanophore response. It is particularly useful in both in vitro and in vivo experiments to evaluate the functions of melatonin receptor signaling.
Used in Pain Management Research:
LUZINDOLE is used as an antagonist in the study of melatonin-mediated antinociception, suggesting that MEL-1B-R plays a role as a mediator of melatonin modulation of pain signaling. This application aids in understanding the underlying mechanisms of pain relief and the potential therapeutic applications of melatonin receptor antagonists.
Used in Anticancer Applications:
Although not explicitly mentioned in the provided materials, LUZINDOLE has been studied for its potential use in cancer research, particularly in the context of understanding the role of melatonin receptors in tumor growth and progression. Further research may reveal its potential applications in this field.

Biological Activity

Melatonin antagonist.

Biochem/physiol Actions

Luzindole is a melatonin (mel) receptor antagonist. It has higher affinity towards the Mel 1b receptor than the Mel 1a receptor subtype.

Iodine-Catalyzed Metal-Free Oxidative Ring Opening of 1-Aryltetrahydro-β-carbolines: Facile Synthesis of C-2 Aroyl and Aryl Methanimino Indole Derivatives

Indole derivatives bearing C-2 substituents have garnered a lot of attention due to their diverse biological activities. Various methods forthe synthesis of these compounds have been reported. Inspired by the hydrolysis of imines, an oxidative ring-opening reaction of 1-aryltetrahydro-β-carbolines with catalytic iodine in aqueous hydrogen peroxide, and also in the presence of appropriate amines, is described for the generation of 2-aroyl and arylmethanimine indole derivatives. The reaction proceeds under mild reaction conditions with ethanol as the solvent or under solvent-free conditions, respectively. This metal-free strategy facilitates the formation of the desired substituted C-2 indoles in moderate to excellent yields. The utility of this reaction is demonstrated by a facile multigram-scale synthesis of Luzindole, a selective melatonin receptor antagonist and an investigational drug against depression and disruption of the circadian rhythm.

Iridium-catalyzed direct synthesis of tryptamine derivatives from indoles: Exploiting N-protected β-amino alcohols as alkylating agents

The selective C3-alkylation of indoles with N-protected ethanolamines involving the "borrowing hydrogen" strategy is described. This method provides convenient and sustainable access to several tryptamine derivatives.
