Morpho‐functional analyses reveal that changes in the chemical structure of a marine bisindole alkaloid alter the cytotoxic effect of its derivatives

open access: yesMicroscopy research and technique (Print), 2022
2,2‐bis(6‐bromo‐1H‐indol‐3‐yl) ethanamine, a marine bisindole alkaloid, showed anticancer property in several tumor cell lines thanks to the presence of a 3,3′‐diindolylmethane scaffold.

Chapter 3 Noniridoid Bisindole Alkaloids

open access: yes, 1995
This chapter discusses that indole is a reactive nucleus prone to dimerization when it is isolated or a part of tryptamine or tryptophan, which themselves are reactive toward many functionalities. For these reasons, bisindoles, the majority of which are of iridoid origin, are frequently isolated in nature. Besides these “dimers,” there exists a growing

From data to discovery: leveraging big data in plant natural products biosynthesis research

open access: yesThe Plant Journal, Volume 122, Issue 6, June 2025.
SUMMARY Plant natural products or specialized metabolites play a vital role in drug discovery and development, with many clinically important derivatives such as the anticancer drugs topotecan (derived from the natural alkaloid camptothecin) and etoposide (derived from the natural polyphenol podophyllotoxin).

2‐Aminoindoles and 2‐Iminoindolines as Viable Precursors of Indole‐Fused Nitrogenated Polyheterocycles

open access: yesAdvanced Synthesis &Catalysis, Volume 367, Issue 6, March 18, 2025.
Abstract The synthesis of architecturally complex polyheterocyclic structures embedding the indole ring represents a growing field of interest. Carbolines and their partially dehydro derivatives, pyrazinoindoles, indoloindoles, azepinoindoles and other medium‐sized derivatives are only some examples of indole‐containing polycyclic compounds featured by

Assessment of Mechanisms Involved in Antinociception Produced by the Alkaloid Caulerpine

open access: yesMolecules, 2014
In previous works we showed that oral administration of caulerpine, a bisindole alkaloid isolated from algae of the genus Caulerpa, produced antinociception when assessed in chemical and thermal models of nociception.

Advances in the Study of Necroptosis in Vascular Dementia: Focus on Blood–Brain Barrier and Neuroinflammation

open access: yesCNS Neuroscience &Therapeutics, Volume 31, Issue 2, February 2025.
Neuroinflammation and blood–brain barrier disruption play key roles in the progression of vascular dementia, and necroptosis is closely associated with vascular dementia. This review guides the prevention and treatment of vascular dementia by discussing the tumor necrosis factor‐α signaling pathway, destruction of endothelial cells, glial cells, and ...
