WebMar 3, 2024 · Covalent chemical probes react specifically with a nucleophilic amino acid on a protein surface using an electrophilic moiety, such as an acrylamide or β-haloketone group. This is beneficial as the off-rate of small-molecule binding is reduced, enhancing target engagement. In organic chemistry, α-halo ketones can be reduced with loss of the halogen atom to form enolates. The α-halo ketones are readily prepared from ketones by various ketone halogenation reactions, and the products are reactive intermediates that can be used for a variety of other chemical reactions. WebIn organic chemistry, an α-haloketoneis a functional groupconsisting of a ketonegroup or more generally a carbonyl group with an α-halogensubstituent. α-haloketones are alkylating agents.
