manganese(II) chelate with dipicolylamine/zinc(II) (DPA/Zn2+) arms (MnLDPA-Zn 2) was developed for adenosine triphosphate (ATP) responsive magnetic resonance imaging (MRI) T1 contrast applications. Compound 2 shows enhanced relaxivity (r1 = 11.52 mM−1 s−1) upon selective ATP binding over other phosphates.
