abstract
A new amide-imine conjugate, 2-hydroxybenzoic acid-(2-hydroxybenzylidene)-hydrazide (L-1), is employed to prepare a single crystal X-ray structurally characterized poly-nuclear Cu(ii) complex (M1). M1 selectively and spatially interacts with cytochromeC(CytC) to allow fluorescence imaging of intracellular translocation events in living cells. Thus, direct visualization of a CytCtranslocation event during an apoptotic process is achieved for the first time. The binding constant and LOD are 7.52 x 10(4)M(-1)and 34.0 nM, respectively.
