Xeniolides A (152) and B (153) are a pair of lactones, related to the prenylated caryophyllene xeniaphyllenol and xenicin, which have been isolated from the soft coral Xenia macrospiculata. Hydroxydilophol (154) is a germacrene-like diterpenoid which has been obtained from the brown alga Dictyota masonii. The full paper, including an X-ray analysis, has appeared on dictyodial and dictyolactone which were obtained from various Dictyota and Aplysia species. A... 

Again, soft corals and gorgonians are a rich source of diterpenoids of 19 structural classes, some of which are specific to them (35, 36). Besides tobacco plants, cembranoid diterpenes are limited to soft corals. Lophotoxin (126) isolated from sea whips of the genus Lophogorgia is a sodium channel inhibitor (3). Xenicin (127) from the soft coral Xenia elongata and briarein A (128) from the gorgonian Briareum asbestinum represent non-cembranolide diterpenes. Diterpenoids of these classes show antimicrobial, cytotoxic, and insecticidal activities. 

Tiny Yellow Springs is a small artists and writers colony east of Dayton. The annual Antioch Writers Workshop brings in budding authors from around the US. The quaint, downtown strip houses a number of earth-friendly eateries and groceries, including Sunrise Cafe (259 Xenia Ave., a 937-767-1065), Winds Cafe Bakery (215 Xenia Ave., a 937-767-1144), and Organic Grocery (230 Keith s Alley St., a 937-767-7215). 

Marine organisms have provided the source of a number of unusual diterpenoid skeleta. Obtusadiol (115) is a bromo-diterpenoid which has been obtained from the red alga Laurencia obtusa. Its structure followed from chemical degradation including a facile ring contraction of the bromohydrin. A group of prenylated caryophyllenes , xeniaphyllenol (116), its 4,5-epoxide, and an enol-ether related to xenicin, ° xeniculin (117), have been found in Xenia macro-... 

There have been no natural products investigations of soft corals from the cool temperate west coast of southern Africa. Soft corals are common along the south-east coast of South Africa and as part of our ongoing search for bioactive metabolites from the marine invertebrate fauna of the Tsitsikamma Marine Reserve we isolated four bioactive xenicane diterpenes, the tsitsixenicins A - D (93 - 96) from the endemic soft coral Capnella thyrsoidea (Family Nephtheidae) [91]. The structures of 93 -96 were delineated from standard analysis of their NMR data and comparison of these data with those published for related compounds e.g. 9-deacetoxy-14,15-deepoxyxeniculin (diastereomic with 93) isolated from the Red Sea soft coral Xenia macrospiculata [92]. 

An unusual intraspecific variation in the structures of the diterpene metabolites produced by the soft coral Eleutherobia aurea (formerly Alcyonium aurea) has been observed from several collections of this species made from the Aliwal Shoal and Sodwana Bay regions [95]. The Sodwana Bay specimens yielded antheliatin (106), zahavins A and B (107,108) [96], sarcodictyin A (109) and eleuthosides A and B (110, 111) [95], In addition to 107, other xenicane diterpenes including 9-deacetoxy-14,15-deepoxyxeniculin (112), 7,8-epoxyzahavin A (113) and xeniolide C (114) were isolated from the Aliwal Shoal specimens of E. aurea [97]. Sarcodictyon A and 9-deacetoxy-14,15-deepoxyxeniculin were isolated previously from the stoloniferous octocoral Sarcodictyon roseum [98] and the soft coral Xenia obscuronata [99]. 

The serious entry of the author into the field of deformation and fracture of polymers started in 1971 during a sabbatical leave at Leeds University in Britain with Professor Ian Ward. The friendly association with Ward has continued until the present. For this reason the book is dedicated first of all to him in appreciation of his long-term friendship. Secondly, however, the book is dedicated in equal measure to my wife Xenia for her enduring support.
