“…These findings are in course of Tsushima, Byrne, Amemiya, and Matsuno (1995), who found that echinenone and β-carotene were the major carotenoids in the gonads of 19 out of the 20 sea urchin species examined. However, carotenoids were not any more present in ESD3 fraction which was obtained by 70% EtOH after extractions with chloroform-95% EtOH and 95% EtOH.…”

“…Indeed, the threefold higher MAA levels and one-third higher peridinin levels normally invested in eggs compared with the maternal tissues of Lobophytum compactum highlight the greater potential of UVR damage to pelagic larvae than sessile adults. Parental provision of carotenoids (Dall et al 1995;Tsushima et al 1995) and MAAs to larvae (Chiocarra et al 1986;Adams and Shick 1996;Fig. 3 Relationship between zooxanthellae densities in adult females following experimental bleaching and protein concentrations 8 months later in both eggs and adult females of Lobophytum compactum, n 100 Carefoot et al 1998) is a common strategy for avoiding UV damage in the early life history stages of other taxa with planktonic larvae, and a number of studies have demonstrated the negative impact of UVR on invertebrate larvae with reduced MAA levels (Gleason and Wellington 1995;Adams and Shick 1996).…”

“…Parental provisioning of resources to eggs has been documented for both MAAs (Chiocarra et al 1986;Adams and Shick 1996;Carefoot et al 1998) and carotenoids (Dall et al 1995;Tsushima et al 1995) for a number of invertebrates with pelagic larval stages. The presence of MAAs decreases mortality of larvae due to UVR in experimental manipulations (Gleason and Wellington 1995).…”

Experimental bleaching reduces the levels of important biochemical parameters in adult tissues and eggs of the soft coral Lobophytum compactum. Protein, lipid, mycosporine-like amino acids (MAAs) and carotenoid concentrations remained lower in bleached adults than in controls for at least 8 months. Reductions in concentrations of all four parameters were greater in eggs than in maternal tissues, potentially jeopardizing egg and larval viability. In particular, reductions in lipids, proteins and carotenoids in tissues of heavily bleached soft corals were ampli®ed approximately twofold in eggs. In comparison, ampli®cation of maternal tissue reductions were not as great for MAAs, suggesting that MAAs are given higher priority in egg provisioning. Our ®nding that MAA levels are normally three times higher in eggs than in unbleached maternal tissues supports the importance of MAAs for larval survival. Twenty months after experimental bleaching the biochemical composition of both adult tissues and their eggs were indistinguishable from those of control (unbleached) soft corals.

“…The cytotoxic acetylenic carotenoids diatoxanthin, and alloxanthin were present in the gonads of Australian and Japanese species of the echinoids Heliocidaris erythrogramma and H. tuberculata (380); in the sea urchin Pseudocentrotus depressus (381); in the sea urchin Peronella japonica (382); in seven species of sea urchins, belonging to the orders Cidaroida, Echinothurioida, Diadematoida, and Arbacioida, as well as pectenolone (308) and 4-keto-cynthiaxanthin (309) (383).…”

This review is a comprehensive survey of acetylenic lipids and their derivatives, obtained from living organisms, that have anticancer activity. Acetylenic metabolites belong to a class of molecules containing triple bond(s). They are found in plants, fungi, microorganisms, and marine invertebrates. Although acetylenes are common as components of terrestrial plants, fungi, and bacteria, it is only within the last 30 years that biologically active polyacetylenes having unusual structural features have been reported from plants, cyanobacteria, algae, invertebrates, and other sources. Naturally occurring aquatic acetylenes are of particular interest since many of them display important biological activities and possess antitumor, antibacterial, antimicrobial, antifouling, antifungal, pesticidal, phototoxic, HIV-inhibitory, and immunosuppressive properties. There is no doubt that they are of great interest, especially for the medicinal and/or pharmaceutical industries. This review presents structures and describes cytotoxic and anticancer activities only for more than 300 acetylenic lipids and their derivatives isolated from living organisms.
