Sulfonate Esters of 1-Hydroxypyridin-2(1H)-one and Ethyl 2-Cyano-2-(hydroxyimino)acetate (Oxyma) as Effective Peptide Coupling Reagents to Replace 1-Hydroxybenzotriazole and 1-Hydroxy-7-azabenzotriazole

family of sulfonate ester-type coupling reagents is described which differs in its leaving group. The sulfonate ester coupling reagents ethyl 2-cyano-2-(naphthalen-2-ylsulfonyloxyimino)acetate (NpsOXY), and ethyl 2-cyano-2-(tosyloxyimino)acetate (TsOXY) are more efficient alternatives to the benzotriazole sulfonate esters in terms of racemization suppression and coupling effectiveness. Both oxyma and
Set forth herein, inter alia, are compositions and methods for treating diseases with prodrugs. Provided herein are prodrug compositions for inhibiting the function of proteins, compositions and methods for treating diseases associated with oxidative compounds, oxidatively-sensitive prodrugs of inhibitors of metalloproteases. and methods of inhibiting metalloproteases using oxidatively-sensitive prodrugs.
The present invention concerns photopolymerisable systems comprising reactive oligomers and/or monomers having ethylenically unsaturated groups and as photoinitiator at least one hydroxamic ester of Formula (I) or (II) or (III).
