“…The crown-of-thorns starfish Acanthaster planci is a large, nocturnal sea star that preys upon coral polyps. Recently, four new carotenoids: 4-ketodeepoxyneoxanthin ( 62 ), 4-keto-4′-hydroxydiatoxanthin ( 63 ), 3′-epigobiusxanthin ( 64 ), and 7,8-dihydrodiadinoxanthin ( 65 ), were isolated from A. planci as minor components along with the major carotenoids 7,8-didehydroastaxanthin, peridininol, and astaxanthin, and several other minor carotenoids including 7,8,7′,8′-tetrahydroastaxanthin, diadinoxanthin, diatoxanthin, and alloxanthin [30]. …”

Marine animals contain various carotenoids that show structural diversity. These marine animals accumulate carotenoids from foods such as algae and other animals and modify them through metabolic reactions. Many of the carotenoids present in marine animals are metabolites of β-carotene, fucoxanthin, peridinin, diatoxanthin, alloxanthin, and astaxanthin, etc. Carotenoids found in these animals provide the food chain as well as metabolic pathways. In the present review, I will describe marine animal carotenoids from natural product chemistry, metabolism, food chain, and chemosystematic viewpoints, and also describe new structural carotenoids isolated from marine animals over the last decade.

“…Furthermore, four new carotenoids; 4-ketodeepoxyneoxanthin, 4-keto-4′-hydroxydiatoxanthin, 3′-epigobiusxanthin, and 7,8-dihydrodiadinoxanthin, were isolated [14]. Details of the structural elucidation of those compounds were described previously [14]. In the present paper, the biosynthetic origins of these compounds are discussed (Figure 2).…”

“…Peridinol, one of the major carotenoids in the crown-of-thorns starfish, was converted from peridinin, which originated from corals, by hydrolysis. Furthermore, four new carotenoids; 4-ketodeepoxyneoxanthin, 4-keto-4′-hydroxydiatoxanthin, 3′-epigobiusxanthin, and 7,8-dihydrodiadinoxanthin, were isolated [14]. Details of the structural elucidation of those compounds were described previously [14].…”

Carotenoids in Marine Invertebrates Living along the Kuroshio Current Coast

Carotenoids of the corals Acropora japonica, A. secale, and A. hyacinthus, the tridacnid clam Tridacna squamosa, the crown-of-thorns starfish Acanthaster planci, and the small sea snail Drupella fragum were investigated. The corals and the tridacnid clam are filter feeders and are associated with symbiotic zooxanthellae. Peridinin and pyrrhoxanthin, which originated from symbiotic zooxanthellae, were found to be major carotenoids in corals and the tridacnid clam. The crown-of-thorns starfish and the sea snail D. fragum are carnivorous and mainly feed on corals. Peridinin-3-acyl esters were major carotenoids in the sea snail D. fragum. On the other hand, ketocarotenoids such as 7,8-didehydroastaxanthin and astaxanthin were major carotenoids in the crown-of-thorns starfish. Carotenoids found in these marine animals closely reflected not only their metabolism but also their food chains.

The marine environment provides a rich source of natural products with potential therapeutic applications.The rate of studies in marine animals, particularly invertebrates has increased considerably in the last few years leading to an increase in the number of bioactive compounds discovered. In this context, this review focuses on the phylum Echinodermata and aims at summarizing and highlighting the bioactive compounds derived from the echinoderms discovered between 2009 and 2013, clarifying their structure, distribution, biosynthetic origin, and biological activity.
