Chen K, Yap L, Park R et al (2011) Evaluation of 64Cu-labeled dipicolylamine (DPA) as a small-molecule PET probe for in vivo imaging of phosphatidylserine exposure. J Nucl Med 52(Suppl 1): 1502. http://jnumedmtg.snmjournals.org/cgi/content/meeting abstract/5...
DPA-NPI showed selective and sensitive fluorescence turn-on type signaling behavior toward Zn2+ ions. The detection of Zn2+ ions was not affected by the presence of commonly encountered physiologically relevant metal ions. Interference from Hg2+, Cd2+, and Cu2+ ions was observed but not ...
Herein, bis(zinc(II)-dipicolylamine)-functionalized sub-2 μm core-shell silica microspheres (SiO@DpaZn) are tailored for rapid and effective N-phosphopeptides enrichment. Due to the coordination of phosphate groups to Zn(II), N-phosphopeptides can be effectively captured under neutral ...
Hydroxo-bridged cubaneA novel tetranuclear complex, [Ni(μ 3-OH)(DPA)] 4(ClO 4) 4 (where DPA = 2,2′-dipicolylamine) has been synthesized, with characterization including electronic and infrared spectroscopy, elemental analysis, mass spectrometry, crystal structure analysis, and variable-...
Small-molecular probe 18 F-labeled bis(zinc(II)-dipicolylamine) complex ( 18 F-FB-DPAZn2) was evaluated for PET imaging of sterile inflammation. In comparison with 18 F-2-deoxy-尾- d -glucose ( 18 F-FDG), 18 F-radiolabeled Annexin V ( 18 F-FB-Annexin V) showed rapid clearance ...
Bis-dipicolylamine-zinc (DPA-Zn) showed selective affinity for anionic phospholipids (11, 12) on the surface of apoptotic bacteria and inflammatory neutrophils. Cy7, a NIR carbocyanine dye, was conjugated to DPA-Zn to form Cy7-DPA-Zn for in vivo NIR imaging of bacterial infection in mice ...
2,2-Dipicolylamine (DPA) based receptors detect Zn2+ with high fidelity. A fluorescent sensor with thiocarbamate-linked DPA turns it into a highly selective module for Ag+ with up to ∼7-fold enhancement of fluorescence. The sensor exhibits a double ratiometric behavior. It also displays an...
Di-2-picolylamine (DPA) is an organic compound that has been shown to possess antioxidant properties when conjugated to form a metal complex. The basis of this study was to determine the effects of DPA on the proliferation and apoptosis of human hepatocellular carcinoma cells and elucidate...
The DPA and diazine units can act as coordination sites for metal cations such as Zn2+, Cd2+ or Hg2+, leading to a blue or red shift in the fluorescence spectra due to the change in the intramolecular charge transfer properties. This phenomenon could become a powerful tool for the ...
Two dipicolylamine (DPA) derivatives with the pyrene and anthracene groups, 1-(pyren-1-yl)-N, N-bis-(pyridine-2-ylmethyl)benzylamine (L1) and 1-(anthracen-9-yl)-N, N-bis-(pyridine-2-ylmethyl)benzylamine (L2) were synthesized, characterized, and their affinitive properties for metal ions...
