Method for Making Industrial Chemicals

A process for producing industrially important chemicals from renewable resources is disclosed. This ?biobased? process employs readily available, renewable resources comprising fatty acids rather than exploiting fossil sources, such as coal and petroleum. In one embodiment of the process 1-octene, along with methyl-9-decenoate and butadiene, is produced from linoleic acid via an enzymemediated isomerization reaction, followed by a metathesis reaction with ethylene. Linoleic acid can be isolated from vegetable oils, such as soybean oil.

METHODS OF MAKING ORGANIC COMPOUNDS BY METATHESIS

Described are methods of making organic compounds by metathesis chemistry. The methods of the invention are particularly useful for making industrially-important organic compounds beginning with starting compositions derived from renewable feedstocks, such as natural oils. The methods make use of a cross-metathesis step with an olefin compound to produce functionalized alkene intermediates having a pre-determined double bond position. Once isolated, the functionalized alkene intermediate can be self-metathesized or cross-metathesized (e.g., with a second functionalized alkene) to produce the desired organic compound or a precursor thereto. The method may be used to make bifunctional organic compounds, such as diacids, diesters, dicarboxylate salts, acid/esters, acid/amines, acid/alcohols, acid/aldehydes, acid/ketones, acid/halides, acid/nitriles, ester/amines, ester/alcohols, ester/aldehydes, ester/ketones, ester/halides, ester/nitriles, and the like.

METHOD TO IDENTIFY MODULATORS OF B-RAF PROTEIN KINASE AND THEIR USE FOR THE TREATMENT OF ANXIETY AND DEPRESSION

The present invention relates to a method for identifying a compound capable of modulating an anxiety or depression disorder comprising the steps of: (a) contacting a composition comprising a B-Raf protein or a B-Raf gene in expressible form or a transcript thereof with a compound under conditions that allow for an interaction of the B-Raf protein or the B-Raf gene or a transcript thereof and the compound; and (b) measuring whether said interaction, if any, results in (i) a change of B-Raf kinase activity compared to B-Raf kinase activity in the absence of said compound; (ii) a modulation of the expression of the B-Raf gene compared to B-Raf gene expression in the absence of said compound; or (iii) the formation of a complex between the compound and the B-Raf protein, wherein such a change in activity, modulation of expression or the formation of a complex is indicative of the compound being a modulator of an anxiety or depression disorder. Further, the invention relates to a method for treating an anxiety or depression disorder in an individual comprising administering to the individual an effective amount of a compound inhibiting B-Raf kinase activity or gene expression and to a use of a compound that inhibits B-Raf kinase activity or gene expression in the manufacture of a pharmaceutical composition for treating an anxiety or depression disorder. Moreover, the invention relates to a method of diagnosing a B-Raf associated anxiety or depression disorder and to a genetically engineered mouse. Finally, the invention also relates to a method of identifying another gene contributing to the pathophysiology of an anxiety or depression disorder apart from B-Raf.

PROCESS FOR CO-PRODUCING OLEFINS AND DIESTERS OR DIACIDS STARTING FROM UNSATURATED FATS

In order to produce both an olefinic fraction and a composition of diacids or diesters of fats, a process is carried out which comprises, in succession: a) metathesis of an unsaturated fat with ethylene in the presence of at least one non-aqueous ionic liquid; b) separating and recycling the ionic liquid used in the first step; c) separating, by distillation, the olefinic fraction (fraction A) from the unsaturated fat mono-ester or mono-basic acid fraction (fraction B) formed in step a); d) homometathesis of the mono-unsaturated fat ester or acid cut (fraction B) which allows the co-production of unsaturated fat diesters or diacids (fraction C) and ethylene which is recycled to the first methathesis step of the process; and e) optionally, recycling the ionic liquid containing the catalyst used in step d). Of particular application to an oleic sunflower oil, an oleic rapeseed oil or to a mixture of mono-alcohol esters of said oils, whereupon the process can produce both an olefinic fraction (mainly composed of 1-decene) and a composition of diesters or diacids wherein, in general, over half of the chains is constituted by unsaturated C18 chains (mainly composed of octadecene-9 1,18-diacid or diester) and to recycle the ethylene employed.
