Progress in the Studies of Triterpene Glycosides From Sea Cucumbers (Holothuroidea, Echinodermata) Between 2017 and 2021

open access: yesNatural Product Communications, 2021
Structural diversity of triterpene glycosides produced by sea cucumbers or holothurians (Holothuroidea, Echinodermata) is extremely high, although all of them are either lanostane derivatives or, rarely, products of their molecular rearrangements.

On Some Plymouth Holothurians [PDF]

open access: yesJournal of the Marine Biological Association of the United Kingdom, 1914
Some of the specific and differential characters of these two species have already been enumerated by Pace (1). Subsequently Norman (2) denied that these two forms were different, so that the literature on them was left in an unsatisfactory state. On investigating these two forms, however, I have obtained sufficient evidence-from the characters of the ...

Effects of Gallic Acid Supplementation on Intestinal Function and Gut Microbial Community Structure in Holothuria leucospilota

open access: yesAquaculture Nutrition, Volume 2026, Issue 1, 2026.
Gallic acid (GA) is a plant‐derived polyphenol with antioxidant and antimicrobial activities, yet its efficacy as a functional feed additive in sea cucumbers remains unclear. Here, we systematically evaluated graded dietary GA supplementation in the tropical sea cucumber Holothuria leucospilota by integrating growth performance, body‐wall nutritional ...

Anticancer Activities of Some Triterpene Glycosides from Holothurians of Cucumariidae, Stichopodidae, Psolidae, Holothuriidae and Synaptidae families

open access: yesNatural Product Communications, 2016
Triterpene glycosides isolated from holothurians are natural products known to possess cytotoxic properties against cancer cells. However, their anticancer prophylactic activity has not been studied sufficiently.

A Quorum-Sensing Inhibitor Strain of Vibrio alginolyticus Blocks Qs-Controlled Phenotypes in Chromobacterium violaceum and Pseudomonas aeruginosa

open access: yesMarine Drugs, 2019
The cell density-dependent mechanism, quorum sensing (QS), regulates the expression of virulence factors. Its inhibition has been proposed as a promising new strategy to prevent bacterial pathogenicity.

Cold Seep Communities in the Sea of Japan Are Species‐Poor and Dominated by a New Species of Provannid Snail

open access: yesJournal of Zoological Systematics and Evolutionary Research, Volume 2026, Issue 1, 2026.
The Sea of Japan is a semi‐enclosed marginal sea in the northwestern Pacific whose bathyal communities exhibit a depauperate species diversity due to anoxic events during the last glacial maximum. Cold seeps associated with chemosynthetic ecosystems were discovered in this region over three decades ago, yet their fauna have not been characterised. Here,

Exploring the Antiparasitic Activity of the Sea Cucumber Isostichopus sp. aff. badionotus From the Northern Coast of Colombia Against Trypanosoma cruzi

open access: yesThe Scientific World Journal, Volume 2026, Issue 1, 2026.
Chagas disease, caused by Trypanosoma cruzi, remains a neglected tropical infection with limited therapeutic options. Sea cucumbers are recognized as rich sources of bioactive sulfated metabolites with potential antiparasitic properties; however, information on the chemistry and trypanocidal activity of Caribbean Isostichopus species is still scarce ...
