Application

N1-(7-Nitro-2,1,3-benzoxadiazol-4-yl)-N1,N2,N2-tris(2-pyridinylmethyl)-1,2-ethanediamine has a high sensitivity for zinc ions. Using fluorescent detection, a linear responsive is observed for Zn2+ con­cen­trations in the range of 1-10 μM. It has good selectivity for Zn2+ in the presence of competing metal ions, such as Ca2+, Mg2+, Fe2+, Fe3+, and Mn2+, and has been used in vivo to determine Zn2+ concentration in pancreatic β cells and zebra fish larvae.

Macrophages use diverse strategies to restrict intracellular pathogens, including either depriving the bacteria of (micro)nutrients such as transition metals or intoxicating them via metal accumulation. Little is known about the chemical warfare between Mycobacterium marinum, a close relative of Mycobacterium

Professional phagocytes have developed an extensive repertoire of autonomous immunity strategies to ensure killing of bacteria. Besides phagosome acidification and the generation of reactive oxygen species, deprivation of nutrients and the lumenal accumulation of toxic metals are essential to kill
