Caging the uncageable: using metal complex release for photochemical control over irreversible inhibition†
Abstract
Photochemical control over irreversible inhibition was shown using Ru(II)-caged inhibitors of cathepsin L. Levels of control were dependent on where the Ru(II) complex was attached to the organic inhibitor, reaching >10 : 1 with optimal placement. A new strategy for photoreleasing Ru(II) fragments from inhibitor–enzyme conjugates is also reported.
