Molluscs with a greatly reduced shell, the opis-thobranchs, lack a physical defence mechanism and are potentially vulnerable to carnivorous predators. Loss of the shell in these animals is compensated for by.

Biogenesis of the enantiomeric The chemistry of some opisthobranch molluscs book 1 and 5 of the marine nudibranch Doriopsilla areolata was investigated by feeding of [C]glucose, [1,C2]glucose, and [1,C2]acetate.

Evidence is presented that supports de novo origin of both compounds via mevalonic acid. Summary. An evolutionary scenario incorporating recent advances in phylogenetic research begins with an opisthobranch-pulmonate common ancestor that was herbivorous and had some diet-derived chemical defense.

The Nudibranchia and their closest relatives, the Notaspidea, form a lineage the ancestors of which had switched to feeding upon sponges and deriving protection from metabolites.

A feature of the conference was the three workshop sessions on chemotaxonomy, applications of marine natural products, and chemical communication.

CHAPMAN Department of Biology, University of California, Los Angeles, California (U.S.A.) ABSTRACT Chapman, D.J., Opisthobranch molluscs represent an ideal model for studying chemo-ecological interac- tions.

3–5 Despite an apparent vulnerability, these invertebrates defend themselves by sophisti- cated mechanisms that involve both behavioural strategies and use of chemical compounds.

1,3,4. A series of isocyanides, compounds 4−11, including diterpenes never before found in Phyllidiid nudibranchs, have been isolated from a Chinese population of the nudibranch Phyllidiella pustulosa.

Three new sesquiterpenes (8, 10, and 11), with eudesmane, guaiane, and bisabolane skeletons, respectively, have been characterized by spectral methods and chemical comparison with known.

The chemistry of Chromodoris spp. Mollusks from the family Chromodorididae (order Nudibranchia) frequently contain oxygenated diterpene metabolites [9].

In an early study on a single specimen of a chromodorid mollusk (possibly Chromodoris reticulata, now known as Goniobranchus reticulatus, ), we identified the new dialdehyde metabolite 1 together with the ring-closed.

Opisthobranch are marine mollusks that are scarcely protected by a shell, which suggests that they possess defensive substances.For instance, when the Pacific aglajid Navanax inermis is damaged by enemies, it secretes a bright-yellow water-insoluble mixture into its slime trail.

From the extracts, three major compounds have been isolated and identified as polyenic compounds 51– This class comprises snails and slugs from saltwater, from freshwater, and from the land.

There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number.

The fossil history of this class goes back to the Late Cambrian. The papers presented at the conference contain a mixture of original research in marine natural products and reviews of some of the more important subjects. The biologists were asked to present papers which could initiate new directions for marine natural products research.

Introduction. Nudibranch gastropod molluscs have traditionally been classified with the Infraclass Opisthobranchia Milne Edwards,which consists of more than species ().Although this taxon is not monophyletic and therefore is considered obsolete (Schrödl et al. ), taxonomic works still refer to “opisthobranchs” for practical reasons (e.g.

Uribe et al. ) and. In particular, the so-called “sea slugs” (Mollusca: Gastropoda: Opisthobranchia) provide some of the most remarkable, and best documented, examples of the evolution of chemical defense in marine organisms –.

With the regression of the external shell and less reliance upon mechanical defense, chemical defense has played a primary role in.Moreover, some bacterial OBFA, such as n-8 and n-8, evidently serve as potential precursors for the biosynthesis of odd-chain PUFA identified in the nudibranchs, such as Δ7,13, as well as n-7 isolated from other marine opisthobranch mollusk, Scaphander lignarius, and possessed activity against a range of human cancer cell.

Introduction Opisthobranch sea slugs (Mollusca: Opisthobranchia) are among the most strikingly colored marine animals. The bright and contrasting external colorations of many opistho-branchs have been considered to be aposematic (Edmunds, ; Gosliner and Behrens, ; Rudman, ) because of the wealth of chemical defenses in these organisms (Cimino and Ghiselin.
