Novel Polypyridyl chelators deplete cellular zinc and destabilize the X‐linked inhibitor of apoptosis protein (XIAP) prior to induction of apoptosis in human prostate and breast cancer cells
X‐linked inhibitor of apoptosis protein (XIAP), inhibits the initiation and execution phases of the apoptotic pathway. XIAP is the most potent member of the inhibitor of apoptosis protein (IAP)Expand

Light activation of a cysteine protease inhibitor: caging of a peptidomimetic nitrile with Ru(II)(bpy)2.
A novel method for caging protease inhibitors is described. The complex [Ru(II)(bpy)(2)(1)(2)](PF(6))(2) (2) was prepared from the nitrile-based peptidomimetic inhibitor Ac-Phe-NHCH(2)CN (1). (1)HExpand

Inhibition of Cathepsin Activity in a Cell‐Based Assay by a Light‐Activated Ruthenium Compound
Light‐activated inhibition of cathepsin activity was demonstrated in a cell‐based assay. Inhibitors of cathepsin K, Cbz‐Leu‐NHCH2CN (2) and Cbz‐Leu‐Ser(OBn)‐CN (3), were caged within the complexesExpand

Caging the uncageable: using metal complex release for photochemical control over irreversible inhibition.
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 organicExpand

New Ru(II) Complex for Dual Activity: Photoinduced Ligand Release and (1)O2 Production.
The new complex [Ru(pydppn)(biq)(py)](2+) (1) undergoes both py photodissociation in CH3CN with Φ500 =0.0070(4) and (1)O2 production with ΦΔ =0.75(7) in CH3 OH from a long-lived (3) ππ* stateExpand
