Convenient synthesis of a variety of photoaffinityprobes was accomplished by utilizing our Ns strategy and novel resin. The synthetic probes were evaluated via the labeling ability with the preseniline 1 C-terminal fragments, which was identified as a therapeutic target for Alzheimer's disease.

Peptide selenoesters have recently emerged as key building blocks for the ligation-based assembly of large polypeptides and proteins. Herein, we report an efficient solid-phase method for the high yielding and epimerisation-free synthesis of peptide selenoesters using a side-chain immobilisation strategy.

electron-deficient arenes, including Lewis basic heterocycles. Here we report a highly Markovnikov-selective, dual-catalytic olefin hydroarylation that tolerates arenes and heteroarenes of any electronic character. Hydrogen atom transfer controls the formation of branched products and arene halogenation specifies attachment points on the aromatic ring. Mono-, di-, tri-, and tetra-substituted alkenes yield Markovnikov

The present invention relates to a cleavable linker platform. In particular, the invention relates to construction of an enzyme cleavable linker platform conjugated to a drug or a diagnostically relevant compound, a biomolecule, and an enzyme cleavable group, for which cleavage of the enzyme cleavable group leads to release of the drug or diagnostically relevant compound.

experiments in which high-resolution studies of enzyme activity and localization are necessary. In this article, we reported a new class of fluorescently Quenched Activity-BasedProbes (qABPs) which are highly modular, and can sensitively image (through multiple enzyme turnovers leading to fluorescence signal amplification) different types of enzyme activities in live mammalian cells with good spatial
