Novel antiproliferative alkyl sulfates from the Mediterranean tunicate Ascidia mentula

A bioassay guided approach was used to isolate two antiproliferative sulfated metabolites, the 3,7,11,15-tetramethyl-hexadecan-1,19-sodium disulfate (1a) and the heneicosane-1,21-sodium disulfate (2a) from the Mediterranean tunicate Ascidia mentula. Their structures were determined by an extensive spectroscopic analysis and chemical methods.

Synthetic polyester from algae oil

Current efforts to technically use microalgae focus on the generation of fuels with a molecular structure identical to crude oil based products. Here we suggest a different approach for the utilization of algae by translating the unique molecular structures of algae oil fatty acids into higher value chemical intermediates and materials. A crude extract from a microalga, the diatom Phaeodactylum tricornutum, was obtained as a multicomponent mixture containing amongst others unsaturated fatty acid (16:1, 18:1, and 20:5) phosphocholine triglycerides. Exposure of this crude algae oil to CO and methanol with the known catalyst precursor [{1,2-(tBu2PCH2) 2C6H4}Pd(OTf)](OTf) resulted in isomerization/methoxycarbonylation of the unsaturated fatty acids into a mixture of linear 1,17- and 1,19-diesters in high purity (>99%). Polycondensation with a mixture of the corresponding diols yielded a novel mixed polyester-17/19.17/19 with an advantageously high melting and crystallization temperature. Algae as feedstock: Crude algae oil from the strain Phaeodactylum tricornutum was transformed into polycondensation-grade purity monomers and thus utilized as feedstock for the production of an algae oil based polyester.
