OCTOBER 20, 2024
Bangyan Xu, Simon J. Mountford, Philip E. Thompson, and Laura E. Edgington-Mitchell ACS Omega 2024 DOI: 10.1021/acsomega.4c07604 Covalent activity-based probes are invaluable tools to monitor protease activity in vitro and in vivo. We recently discovered that dimethyl sulfoxonium ylides (SYs) bind selectively to cysteine cathepsin proteases in a mechanism-dependent manner.
