“…from Rottnest Island, Western Australia, 172 has been proposed on the basis of total synthesis. 173 Six additional acetylenic enol ethers, petroraspailynes A1 202, A2 203, A3 204, B1 205, B2 206 and B3 207, and the alcohol 208, the absolute configurations of which were determined by Mosher's method, have been isolated from a Korean species of Petrosia. 174 Seven additional cytotoxic polyacetylenes, (3S,14S)-petrocortyne A 209, petrotetrayndiols A 210, B 211 and C 212, dideoxypetrosynols E 213 and F 214, and nor-3S,14S-petrocortyne A 215, were also isolated from a Petrosia sp.…”

“…5 Among the materials investigated were polymers such as thermoplastic polyurethanes, silicone-polycarbonate block copolymers, ethylene-vinyl acetate copolymers, flexible polyesters, and various thermoplastic elastomers and polyolefin blends. 6 We also tried to solve the problem of the toxicity of plasticized PVC by use of a polyurethane (PU) and polypropylene (PP) blend as a blood bag material. PUs are one of the few synthetic materials with good biocompatibility and other performance characteristics, which make them suitable for a wide range of medical application such as for blood bags and surgical gloves and for a wide range of high-risk applications such as catheters, synthetic veins, and, more recently, wound dressings.…”

ABSTRACT:Blends with different ratios of thermoplastic polyurethane/polypropylene (TPU/PP) were prepared by melt mixing using an internal Haake mixer. Properties of the blends were investigated using SEM micrographs of cryofractures and measurement of the mechanical strength, water absorption, cell culture, and platelet adhesion in vitro tests, which were compared with those of PVC blood bags. The effect of the addition of the ethylene-vinyl acetate (EVA) copolymer on the TPU/PP blend properties was investigated. The results indicated that a TPU/PP/EVA ϭ 80/ 20/5 blend can be used as a new blood bag material. It was observed that the blend is homogeneous with higher mechanical strength than that of the commercial PVC blood bag. This blend also showed a compatible cell response in contact with L929 fibroblast cells and fewer tendencies to interaction with platelets compared to the PVC blood bag. Although the blends were immissible and no chemical reaction at the interface could be found, the blood compatibility of the blends were improved.

Marine Natural Products from Flora and Fauna of the Western Australian Coast: Taxonomy, Isolation and Biological Activity

Marine natural products occurring along the Western Australian coastline are the focus of this review. Western Australia covers one-third of the Australian coast, from tropical waters in the far north of the state to cooler temperate and Antarctic waters in the south. Over 40 years of research has resulted in the identification of a number of different types of secondary metabolites including terpenoids, alkaloids, polyketides, fatty acid derivatives, peptides and arsenic-containing natural products. Many of these compounds have been reported to display a variety of bioactivities. A description of the compound classes and their associated bioactivities from marine organisms found along the Western Australian coastline is presented.
