Activation of Metal Complexes With Ultrasound Waves for Targeted Anticancer Therapy

Angewandte Chemie International Edition, EarlyView.
Ultrasound enables non‐invasive activation of metal‐based therapeutics deep within tumors. Acoustic cavitation can drive sonodynamic reactive oxygen species generation or mechanochemical metal–ligand bond dissociation, enabling controlled release of bioactive payloads.

Synthesis of a Stable Hydrophilic trans‐Cyclooctene Amino Acid Unlocks Fast Bioorthogonal Click Chemistry for the Generation of Antibody‐Drug Conjugates by Genetic Code Expansion

Angewandte Chemie International Edition, EarlyView.
A novel trans‐cyclooctene (TCO) based noncanonical amino acid (ncAA) is reported, characterized by high hydrophilicity and remarkable stability to trans‐cis isomerization. Its incorporation via genetic code expansion into an antibody and subsequent conjugation resulted in a highly efficacious antibody‐drug conjugate (ADC).
