The speciation and distribution of zinc (II) within cells is not well established and the range of zinc (II) probes available are of limited use. The quest was to develop responsive lanthanide complexes to bind selectively and respond (by change in hydration state) to biologically relevant concentrations of zinc at physiological pH for possible application in MRI and luminescence. A pyridyl sulfonamide ligand with an a-CH(_2)NHSO(_2)CF(_3) substituent was found to have the desired properties for strong zinc (II) coordination.

Abstract:
Discovery of the antitumor activity of platinum complex, cisplatin, cis-Pt(NH3)2Cl2, and later carboplatin and oxaliplatin, led to the intensive investigation of the potential antitumor activity of the huge number of platinum complexes. Furthermore, it is well-known that platinum complexes express toxicity, numerous side effects and resistance, so the scientists make a lot of efforts to synthetize, beside Pt(II) and Pt(IV), other non-platinum compounds with potential antitumor activity, such as Pd(II), Ru(II/III) and Au(III) complexes. The goal of this study is to summarize the results of the

Abstract:
Rhizoferrin, a siderophore produced by Rhizopus arrhizus, has been shown in previous studies to be an outstanding Fe carrier to plants. However, calculations based on stability constants and thermodynamic equilibrium lead to contradicting conclusions. In this study a kinetic approach was employed to elucidate this apparent contradiction and to determine the behavior of rhizoferrin under conditions representing soil and nutrient solutions. Stability of Fe3+ complexes in nutrient solution, rate of metal exchange with Ca, and rate of Fe extraction by the free ligand were monitored for rhizoferrin
