The effect of metalloprotein inhibitors on cellular metal ion content and distribution.

ABSTRACT: With metalloproteins garnering increased interest as therapeutic targets, designing target-specific metalloprotein inhibitors (MPi) is of substantial importance. However, in many respects, the development and evaluation of MPi lags behind that of conventional small molecule therapeutics. Core concerns around MPi, such as target selectivity and potential disruption of metal ion homeostasis linger. Herein, we used a suite of analytical methods, including energy-dispersive X-ray spectroscopy (EDX), inductively coupled plasma atomic emission spectroscopy (ICP-OES), and synchrotron X-ray fluorescence microscopy (SXRF) to investigate the effect of several MPi on cellular metal ion distribution and homeostasis. The results reveal that at therapeutically relevant concentrations, the tested MPi hav
