标题 :ENANTIOSELECTIVE, ENZYMATIC SYNTHESIS OF S(-) and R(+) ESTERS OF 4-HYDROXY-CYCLOPENTENE-1-ONE AND ITS 2',2'-DIMETHYLPROPANE-1',3'-DIOL-KETAL
发明人：SCHAPOEHLER STEFAN B; SCHEPER THOMAS; SCHUEGERL KARL
权利人:EUROP COMMUNITIES
摘要:The S(-) and R(+) esters of 4-hydroxy-cyclopentene-1-one and its 2',2'-dimethylpropane 1',3'-diol-ketal are produced by direct, enantioselective, enzymatic synthesis by reacting the corresponding 4-hydroxy compounds with an ester as acyl donor in the presence of an enzyme. The esters obtained are valuable intermediate products for stereospecific synthesis, in particular for the stereoselective synthesis of chemical compounds, in particular stable, storable, chiral prostaglandin derivatives, especially storable chiral prostaglandinsynthone.

摘要:The present invention is generally directed to diester-based lubricant compositions comprising one or more isomeric mixtures of diester species. The present invention is also directed to methods of making these and other similar lubricant compositions. In some embodiments, the methods for making such diester-based lubricants utilize a biomass precursor material from which mono-unsaturated free lipid species can be provided or otherwise generated, wherein such mono-unsaturated free lipid species are converted to isomeric diol species en route to the synthesis of diester species for use as/in the diester-based lubricant compositions.

标题:Method of enzyme immobilization on a particulate silica carrier for synthesis inorganic media
发明人：PEDERSEN SVEN; LARSEN ANNE MORKEBERG; AASMUL PER
权利人:NOVO NORDISK AS
摘要:An immobilized enzyme is prepared for synthesis in a mainly organic medium devoid of free water. In one embodiment, an enzyme and liquid binder are introduced by atomization onto a particulate silica carrier having a particle size below 100 μm in a granulator and simultaneously granulating to form the immobilized enzyme. In another embodiment, a liquid enzyme composition is contacted with the particulate silica carrier to obtain a particulate immobilized enzyme having a particle size below 100 μm, the immobilized enzyme is introduced into granulator, a liquid binder is introduced into the granulator and granulation is carried out. The enzyme is preferably a lipase such as a thermostable lipase, and the immobilized lipase is used for interesterification of fats or synthesis of fatty acid esters.

摘要:The present invention describes novel nitrosated and/or nitrosylated taxanes, and novel compositions comprising at least one nitrosated and/or nitrosylated taxane, and, optionally, at least one compound that donates, transfers or releases nitric oxide, elevates endogenous levels of endothelium-derived relaxing factor, stimulates endogenous synthesis of nitric oxide or is a substrate for nitric oxide synthase and/or at least one therapeutic agent. The present invention also provides novel compositions comprising at least one taxane and at least one compound that donates, transfers or releases nitric oxide, elevates endogenous levels of endothelium-derived relaxing factor, stimulates endogenous synthesis of nitric oxide or is a substrate for nitric oxide synthase and/or at least one therapeutic agent. The compounds and compositions of the present invention can also be bound to a matrix. The present invention also provides methods for treating or preventing cardiovascular diseases and disorders, autoimmune diseases, pathological conditions resulting from abnormal cell proliferation, polycystic kidney disease, inflammatory disease, preserving organs and/or tissues or to inhibit wound contraction, particularly the prophylactic and/or therapeutic treatment of restenosis, by administering nitrosated and/or nitrosylated taxane or parent taxanes in combination with nitric oxide donors that are capable of releasing nitric oxide or indirectly delivering or transferring nitric oxide to targeted sites under physiological conditions.
