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 ...

The Therapeutic Effects of Bioactive Compounds on Colorectal Cancer via PI3K/Akt/mTOR Signaling Pathway: A Critical Review

open access: yesFood Science &Nutrition, Volume 12, Issue 12, Page 9951-9973, December 2024.
This study discussed the therapeutic capacity of various polyphenols, terpenoids, and alkaloids on CRC via the PI3K/Akt/mTOR pathway. Each bioactive component causes various physiological processes, such as triggering free radical production, disruption of mitochondrial membrane potential, cell cycle arrest, inhibition of CRC stem cell migration ...

C. elegans-based screen identifies lysosome-damaging alkaloids that induce STAT3-dependent lysosomal cell death

open access: yesProtein & Cell, 2018
Lysosomes are degradation and signaling centers within the cell, and their dysfunction impairs a wide variety of cellular processes. To understand the cellular effect of lysosome damage, we screened natural small-molecule compounds that induce lysosomal ...

Bisindoles : synthesis and reactions

open access: yes, 1999
In this thesis, synthesis of various bisindoles have beendeveloped.2,3-Bis-(3-indolyl) succinic acid derivatives wereobtained via iodine promoted coupling of the trianion ofindole-3-acetic acid (IAA) or from the dianion of themethylester of IAA. These compounds were converted to2,3-bis(3-indolyl) maleimides (arcyriarubin analogues) by DDQoxidation ...

A Facile Synthesis of Deaza-Analogues of the Bisindole Marine Alkaloid Topsentin

open access: yesMolecules, 2013
A series of substituted ethyl 1-[(tert-butoxycarbonyl)amino]-2-methyl-5- (1-methyl-1H-indol-3-yl)-4-[(1-methyl-1H-indol-3-yl)carbonyl]-1H-pyrrole-3-carboxylates were prepared in excellent yields (82-98%) by one-pot reactions between β-dicarbonyl ...
