New Glucocerebrosidase Inhibitors by Exploration of Chemical Diversity of <i>N</i>-Substituted Aminocyclitols Using Click Chemistry and in Situ Screening
the reaction can be carried out in an aqueous system, the resulting library members can be screened in situ with minimal manipulation. From the preliminary GCase inhibition data, the most potent library members have been individually resynthesized for further biological screening and complete characterization. Some of the library members have shown biochemical data (IC50, Ki, and stabilization ratio)
Disclosed herein are analogs of Salinosporamide A, having the Formula I as follows:
Like Salinosporamide A, the compounds of the present invention will inhibit the proteasome, an intracellular enzyme complex that destroys proteins the cell no longer needs. Without the proteasome, proteins would build up and clog cellular machinery. Fast-growing cancer cells make especially heavy use of the proteasome, so thwarting its action is a compelling drug strategy.
The invention features compositions comprising at least one monomer that comprises a cyclic dithiane moiety attached to a (meth)acryloyl moiety. The composition may optionally contain additional polymerizable compounds, such as ethylenically unsaturated compounds, that are typically used in dental compositions.
The invention provides a palladium-promoted hydrolytic polypeptide cleavage process which selectively cleaves the polypeptide at a Cys-His cleavage site comprising solubilizing the polypeptide in a reaction mixture comprised of a palladium promoter dissolved in a high-concentration formic acid, wherein the concentration of the formic acid in the reaction mixture is between about 1 to about 22 molar.
