A two-component initiator system having accelerators for curing polymerizable materials comprising the following components: (a) a hydroperoxide compound containing one or more hydroperoxide groups that are bound to a tertiary carbon; (b) a thiourea derivative; and (c) as accelerator, a copper compound which is soluble in the preparation is preferably free of amine and is particularly suited for polymerizable dental compositions.
Structure-Guided Design of Novel Thiazolidine Inhibitors of <i>O</i>-Acetyl Serine Sulfhydrylase from Mycobacterium tuberculosis
catalyzes the formation of l-cysteine from O-acetyl serine and hydrogen sulfide. Here we report nanomolar thiazolidineinhibitors of Mycobacterium tuberculosis CysK1 developed by rational inhibitordesign. The thiazolidine compounds were discovered using the crystal structure of a CysK1–peptide inhibitor complex as template. Pharmacophore modeling and subsequent in vitro screening resulted in an initial
