The reactions of [ Ru2(O2CCH3) 4Cl] with 2-aminopyridine (Hamp) and 2-amino-4-methylpyridine (Hammp) afforded two novel Ru2 complexes, [ Ru2(amp) 4Cl2] (1) and [ Ru2(ammp) 4Cl2] (2), respectively. Single crystal X-ray diffraction analyses revealed that 1 and 2 adopted typical paddlewheel-type structures, where the Ru2 units are coordinated with four aminopyridinate ligands with a cis-2: 2 arrangement at the equatorial positions and two chloride ligands at the axial positions. The stabilities of 1 and 2 were supported by unrestricted density functional theory (uDFT) calculations. The zero-point energies of the three structural isomers (trans-2: 2, 3: 1, and 4: 0 arrangements) of 1 and 2 were less stable than those of the respective cis-2: 2 arrangements. Temperature-dependences of the magnetic susceptibility measurements and uDFT calculations showed that the oxidation and spin states of the Ru2 units in 1 and 2 were commonly Ru2 6+ and triplet states, respectively. Cyclic voltammetry showed that 1 and 2 underwent oneelectron reduction processes, i. e., 1/1-and 2/2-, at redox potentials (E1/2) of -0.08 and -0.18 V vs. SCE, respectively. These results agreed well with the DFT-calculated E1/2 values of 1 (-0.08 V vs. SCE) and 2 (-0.18 V vs. SCE) and were theoretically attributed to Ru2-centred (d*(Ru2)) redoxes. Moreover, 1 and 2 showed unique near-infrared absorption bands at approximately 1200-1500 nm, which were theoretically attributed to the ligand-to-metal charge transfer (LMCT) with p(amp or ammp). d*(Ru2) transition characteristics.

Despite the crucial roles of duodenal cytochrome b (Dcytb), divalent metal transporter 1 (DMT1), ferritin light chain (Ftl1), ferroportin 1 (FPN1), transferrin receptor 1 (TfR1), and hepcidin antimicrobial peptide (Ramp) in Fe metabolism, no studies have investigated the modulations of these genes during Fe repletion with fermented milks. Analysis included Fe status markers and gene and protein expression in enterocytes of control and anemic animals fed fermented milks. Fermented goat's milk up-regulated enterocyte Dcytb, DMT1, FPN1, and Ftll and down-regulated TfR1 and Hamp gene expression in control and anemic animals. Anemia decreased Dcytb, DMT1, and Ftll in animals fed fermented cow's milk and up-regulated TfR1 and Ramp expression. Fe overload down-regulated Dcytb and TfR1 in animals fed fermented cow's milk and up-regulated DMT1 and FPN1 gene expression. Fermented goat's milk increased expression of duodenal Dcytb, DMT1, and FPN1 and decreased Ramp and TfR1, improving Fe metabolism during anemia recovery.
