Mitogen-activated protein (MAP) kinases are responsible for many cellular functions, and their malfunction manifests itself in several human diseases. Usually, monitoring the phosphorylation states of MAP kinases in vitro requires the preparation and puri

The present invention relates to bacteria-targeted contrast agents for magnetic resonance imaging (MRI). In particular, the present invention relates to bacteria targeted MRI contrast agents that can be used to detect bacteria in vivo or in vitro. In certain embodiments, the contrast agents comprise a metal chelate conjugated to at least two Zn-dipicolylamine groups.

A bacteria-targeted MR contrast agent, Zn-1, consisting of two Zn-dipicolylamine (Zn-dpa) groups conjugated to a GdIII chelate has been synthesized and characterized. In vitro studies with S. aureus and E. coli show that Zn-1 exhibits a significant improvement in bacteria labeling efficiency vs. control. Studies with a structural analogue, Zn-2, indicate that removal of one Zn-dpa moiety dramatically reduces the agent's affinity for bacteria. The ability of Zn-1 to significantly reduce the T1 of labeled vs. unlabeled bacteria, resulting in enhanced MR image contrast, demonstrates its potential for visualizing bacterial infections in vivo.
