Functional protein- and antibody-conjugates for intra- and extracellular targeting

In this presentation, l will focus on the chemical modification of functional proteins for for pharmaceutical and medicinal applications.¹ In my laboratory, we use a combined approach of recently developed chemoselective reactions and enzymatic ligations, for instance the so-called P5-² or Tub-tag³-labeling, for bioconjugation.

By generating stable antibody-drug conjugates (ADCs),^2b structurally defined multivalent scaffolds⁴ or cell-permeable antibodies via conjugating cyclic cell-penetrating peptides,⁵ we provide new modalities for most challenging pharmaceutical targets, including next generation cancer therapeutics or novel inhibitors against viral infections.
