This study demonstrates that verapamil and a newly synthesized verapamil derivative, NMeOHI(2), behave as apoptogens in multidrug resistance protein 1 (MRP1)-expressing cells. When treated with either verapamil or NMeOHI(2), surprisingly, baby hamster kidney-21 (BHK) cells transfected with human MRP1 were killed. Because parental BHK cells were not, as well(More)
In the perspective of expanding the use of annexin A5 (anx A5) as radioactive tracer of cell death in vivo, we recently described its radiolabeling with (99m)Tc-tricarbonyl [(99m)Tc(H(2)O)(3)(CO)(3)](+) via the mercaptobutyrimidyl group (anx A5-SH). The aim of the present article was to compare this new method with the HYNIC strategy (anx A5-HYNIC),(More)
Antisense oligodeoxynucleotides (ODNs) have great promise for therapy. Oligomers labeled with gamma-emitting radioelements have great promise for diagnosis. These radiolabeled oligomers can be used to identify the presence of a particular messenger RNA through simple external detection of radioactivity by means of scintigraphy. This review evaluates the(More)
The synthesis of two new iron chelators built on the tris-l-serine trilactone scaffold of enterobactin and bearing a 8-hydroxyquinoline (oxinobactin) or 8-hydroxyquinoline-5-sulfonate (sulfoxinobactin) unit has been described. The X-ray structure of the ferric oxinobactin has been determined, exhibiting a slightly distorted octahedral environment for(More)
This paper describes the synthesis of four new polyisocyanides (three diisocyanides and one triisocyanide). The complexation of 99mTc with these ligands is also studied through chromatography and revealed the formation of hexacoordinated 99mTc+1 complexes. Finally, biodistributions of these complexes in mice are given and compared. Heart captations are(More)
The nickel(ii) complexes of three unsymmetrical thiosemicarbazone-based ligands featuring a sterically hindered salicylidene (1), aminophenol (2) or thiophenol (3) moiety were synthesized and structurally characterized. The metal ion lies in an almost square planar geometry in all the complexes. The cyclic voltammetry (CV) curve of 1 shows an irreversible(More)
The sterically hindered bis(2-aminophenyl)dipyrrin ligand H3NL was prepared. X-ray diffraction discloses a bifurcated hydrogen bonding network involving the dipyrrin and one aniline ring. The reaction of H3NL with one equivalent of nickel(II) in the air produces a paramagnetic neutral complex, which absorbs intensively in the Vis-NIR region. Its electron(More)
