Attaching palladium catalysts to antibodies [PDF]

Bioorganic & Medicinal Chemistry, 2021
Antibody-directed enzyme prodrug therapy (ADEPT) is a powerful concept in which antibody targeting is linked to enzymatic prodrug activation. The work herein describes the first steps in the development of a technology analogous to ADEPT but in which a palladium catalyst is attached of an antibody rather than an enzyme.
