The intertidal pulmonate limpetTrimusculus reticulatus, which is found in caves or crevices along the California coast, was previously reported to contain two novel diterpenoids, 6β-isovaleroxylabda-8,13-dien-7α,15-diol (1) and 2α,7α-diacetoxy-6β-isovaleroxylabda-8,13-dien-15-ol (2). Dissection of the animals prior to extraction revealed that the diterpenoids were concentrated in the mantle, foot, and mucus, but not in the viscera. The presence ofT. reticulatus or its mucus was toxic to veliger… Expand
Multiple Functions for Secondary Metabolites in Encrusting Marine Invertebrates
It was found that various fractions displayed the same type of bioactivity, while compounds from the same fraction were responsible for multiple activities, suggesting that secondary metabolites are multiple-purpose tools in nature, which is relevant to the understanding of species ecology and evolution.

New diterpenes from the marine pulmonate Trimusculus peruvianus
The isolation from the marine pulmonate Trimusculus peruvianus of two new labdane diterpenes closely related to the above mentioned characteristics are described. Expand
The chemistry of marine pulmonate gastropods.
Secondary metabolites from pulmonate molluscs of the genera Siphonaria, Onchidium, and Trimusculus are described and strong resemblance between class I and cephalaspidean metabolites and between class II and onchidiid metabolites encourages speculation about their biosynthetic and phylogenetic relationship. Expand
Unlike other marine pulmonates (Siphonariidae and Onchidellidae), T. costatus does not have large multicellular glands encapsulated in a well-developed muscle layer, and is more similar in structure to those of some terrestrial pulmonate. Expand
Terpenoids in Marine Heterobranch Molluscs
Overall, a huge variety of structures is found, indicating that chemodiversity correlates to the amazing biodiversity of this fascinating group of molluscs. Expand
Bioactive Compounds from Marine Heterobranchs
Heterobranch molluscs are extremely interesting in regard to the study of marine natural products in terms of both chemical ecology and biotechnology studies, providing many leads for further detailed research in these fields in the near future. Expand
Antifouling Sesterterpenes from the New Zealand Marine Sponge Semitaspongia Bactriana
Three antifouling sesterterpenes have been isolated from the New Zealand marine sponge Semitaspongia bactriana with toxicity against the diatom Nitzschia closterium and bryozoan Bugula neritina and show the most promise for incorporation of either these metabolites, or synthetic analogues, as biocides to produce paints or plastics with AF properties. Expand
Natural marine products with antifouling activities
This chapter pursues the objective of reviewing, although not exhaustively, the recent research on marine natural AF products, to focus on interesting cases that would allow the reader to understand the main trends that emerge from this field, and indicate future and promising directions of research.

Mantle defensive response of marine pulmonate Trimusculus peruvianus
The marine pulmonate Trimusculus peruvianus (Sowerby, 1835) which is found in caves or narrow crevices along the Chilean coast was studied to determine a possible chemical defense against theExpand

This review provides a taxonomic breakdown of the published research on marine molluscan natural products and the medicinal products currently derived frommolluscs, in order to identify priority targets and strategies for future research. Expand


Evidence of a defensive role for limatulone, a novel triterpene from the intertidal limpet Collisella limatula
Experiments and field observations strongly suggest that limatulone acts as a potent chemical defense against some intertidal predators, and may act to defend foraging limpets from predatory fishes in tidepools and on intert tidal boulders. Expand
An anti-predator chemical defense of the marine pulmonate gastropod Trimusculus reticulatus (Sowerby)
Feeding preference experiments with the crab Pachygrapsus crassipes indicated that the mucous defense of Trimusculus reticulatus is not effective against this predator. Expand
Chemical induction of larval settlement and metamorphosis in the reef-building tube worm Phragmatopoma californica (Sabellariidae: Polychaeta)
Naturally-occurring lipophilic inducers of larval settlement and metamorphosis wer isolated and identified for Phragmatopoma californica, a gregarious tube worm from southern California, and the larval response was contact-dependent, highly specific, and concentration-dependent. Expand
A chemical defense mechanism for the nudibranch cadlina luteomarginata
Abstract The nudibranch Cadlina luteomarginata from San Diego, California, concentrates selected metabolites from the sponges that constitute its diet. Gut analyses revealed that C. leutomarginataExpand
Diterpenes from the marine pulmonate trimusculus reticulatus
Abstract The marine pulmonate Trimusculus reticulatus contains 6β-isovaleroxylabda-8,13-dien-7α,15-diol ( 1 ) and 2α,7α-diacetoxy-6β-isovaleroxylabda-8,13-dien-15-ol ( 2 ). The diol 1 is found in theExpand
Screening and bioassays for biologically-active substances from forty marine sponge species from San Diego, California, USA
The discussion relates the possession of biologically-active substances to the ecology of each sponge species; for example, sponges with antimicrobial substances are rarely overgrown. Expand
Chemical defense and evolutionary ecology of dorid nudibranchs and some other opisthobranch gastropods
In the evolution of dorid nudibranchs and some other opisthobranch gastropods loss of the shell is correlated with the presence of defense mechanisms based upon chemicals derived from food, and food dependencies have constrained the adaptive radiation of oplsthobranchs. Expand
