Compounds of formula (I) and salts thereof: wherein R1, R2, R3, R4 are defined herein. Compounds of formula (I) and salts thereof have been found to inhibit the binding of the BET family of bromodomain proteins to, for example, acetylated lysine residues and thus may have use in therapy, for example in the treatment of autoimmune and inflammatory diseases, such as rheumatoid arthritis; and cancers.
Ligations: The title immunoglobin (Ig) domain was chemoenzymatically synthesized. The domain was divided into three segments and N‐ and S‐protected peptide thioesters were synthesized by solid‐phase peptide synthesis. The one‐pot sequential ligation was achieved by using Ag+‐free and Ag+‐assisted activation of the thioester. After folding and enzymatic transfer of the synthetic glycan, the desired

can be achieved by redox decarboxylation of distal N-hydroxyphthalimide esters of protected aspartic, glutamic or α-aminoadipic acids via radical addition to methylideneoxazolidinones. The products are useful for solid-supported syntheses of robust bioactive carbocyclic peptide analogs. Yields of reactive primary radical addition are superior to those of more stabilized radicals, and the reaction fails
A catalytic method for the formation of amide bonds was developed in which the amidation of N-hydroxyimino esters with a broad range of amino acid tert-butyl esters is promoted by a niobium catalyst in the absence of solvent. Contrary to the predominant protocol based on reagent control commonly applied to amidation reactions, this study provides insight into an approach based on substrate control
