Provided herein are aryl and heteroaryl sulfone and sulfoxide modifying agents for facile and selective chemical alteration of proteins at thiol in cysteine residues, thiol- and selenol-containing moieties. Also provided herein are TAK242 derivatives for selective reaction with amino-containing compounds. The modifying agents disclosed herein can be used under mild reaction conditions for a variety of conjugation applications in molecules that possess amino, thiol or selenol functionalities. Also provided herein are methods of chemoselectively modifying a moiety containing the amino acids cysteine or lysine. Provided herein are CCR5 and CXCR antagonist derivatives modified for bioconjugation to macromolecules.
