Application

KB02yne is a cysteine-reactive small-molecule fragment for chemoproteomic and ligandability studies for both traditionally druggable proteins as well as ″undruggable,″ or difficult-to-target, proteins. This fragment electrophile is the functionalized version of KB02 (912131).

Reversible covalency, achieved with, for instance, highly electron-deficient olefins, offers a compelling strategy to design chemical probes and drugs that benefit from the sustained target engagement afforded by irreversible compounds, while avoiding permanent protein modification. Reversible covalency has mainly been

Covalent ligands are a versatile class of chemical probes and drugs that can target noncanonical sites on proteins and display differentiated pharmacodynamic properties. Chemical proteomic methods have been introduced that leverage electrophilic fragments to globally profile the covalent ligandability of

Ligand-dependent protein degradation has emerged as a compelling strategy to pharmacologically control the protein content of cells. So far, however, only a limited number of E3 ligases have been found to support this process. Here, we use a chemical proteomic
