efficient cobalt-catalyzed reductive coupling reaction of alkyl halides with electron-withdrawing alkenes (CH2CR1EWG, EWG = electron-withdrawing group) in the presence of water and zinc powder in acetonitrile to give the corresponding Michael-type addition product (RCH2CR1EWG) was described. The methodology is versatile such that unactivated primary, secondary, and tertiary alkyl bromides and iodides and

The invention relates to an iodinated CT contrast agent made of fatty acid derivatives for noninvasive visualisation and quantification of the brown and/or beige adipose tissue (BAT) or for imaging the heart and/or liver of a subject. Advantageously, this contrast agent is to be taken orally which is a breakthrough in CT imaging. Image resolution by CT is significantly enhanced compared to PET.

The present invention is directed to pharmaceutical compositions, and method for preparing pharmaceutical compositions, comprising a cross-linked matrix physically entrapping at least one therapeutic agent. The matrix may comprise one or more phases in addition to an aqueous phase, such as a solid and/or oil phase. The matrix of the invention has at least one controlled release in-vivo kinetic profile, and may have additional profiles for the same agent. The matrix may also comprise more than one therapeutic agent, and each additional therapeutic agent may have one or more controlled release in-vivo kinetic profile.

The present invention relates to novel mutant thioesterase enzymes and naturally-occurring equivalents thereof, compositions made from such enzymes and uses of thioesterase enzymes. In particular, the present invention provides mutant thioesterase enzymes that have altered properties, for example, altered substrate specificity, altered activity, altered selectivity, and/or altered proportional yields in the product mixtures. The present invention also provides polynucleotides encoding such mutant thioesterase enzymes, and vectors and host cells comprising such polynucleotides. The invention further provides for novel uses of thioesterases in the production of various fatty acid derivatives, which are useful as, or as components of, industrial chemicals and fuels.
