The conditions for achieving the maximal unquenched orbital angular momentum L = 3 and highest magnetic anisotropy in mononuclear 3d complexes with axial coordination symmetry are examined terms of ligand field theory. It is shown that, apart from known linear two-coordinate 3d7 complex CoII(C(SiMe2ONaph)3)2 characterized by record single-molecule magnet (SMM) performance (with largest spin-rev...

Reaction of bis-(pyridin-3-ylmeth-yl)sulfane (L) with cobalt(II) chloride in methanol led to the formation of the title coordination polymer, [CoCl2(C12H12N2S)(CH3OH)2] n , in which the CoII cation lies on a crystallographic inversion centre and the S atom of the L ligand lies on a twofold rotation axis. Each CoII ion is coordinated by two pyridine N atoms from two bridging L ligands, two O ato...

We assessed the in vitro toxicity of tenofovir (TFV) and compared it with those of zidovudine (AZT), didanosine (ddI), ritonavir (RTV), and lopinavir (LPV) alone and in combination in human renal proximal tubule epithelial cells (RPTECs). The cells were treated with various concentrations and combinations of the tested antiretrovirals for up to 22 days, and cytotoxicity was determined. In addit...

The synthesis and the structure of the new potentially heptadentate ligand 1,3-bis-(3-oxo-3-(2-hydroxyphenyl)-propionyl)-2-methoxybenzene (H5L) is described. The reaction in pyridine or DMF of this ligand with various M(AcO)2 salts (M = NiII, CoII, MnII) leads to very different products depending on the metal. Thus, the dinuclear complexes [M2(H3L)2(py)4] (M = NiII, 1; CoII, 2) or the linear zi...

Due to their strict maternal inheritance in most animals and plants, mitochondrial genomes are predicted to accumulate mutations that are beneficial or neutral in females but harmful in males. Although a few male-harming mtDNA mutations have been identified, consistent with this 'Mother's Curse', their effect on females has been largely unexplored. Here, we identify COII(G177S), a mtDNA hypomor...

Pulse dipolar electron paramagnetic resonance spectroscopy (PDS) is continuously furthering the understanding of chemical and biological assemblies through distance measurements in nanometer range. New paramagnets pulse sequences can provide structural insights not accessible other techniques. In pursuit alternative spin centers for PDS, we synthesized a low-spin CoII complex bearing nitroxide ...

An octahedral cobalt(III) complex, trans-[(Me2bpb)Co(bzlan)2]ClO4 (1), with H2Me2bpb = N,N’-(4,5-dimethyl-1,2-phenylene)dipicolinamide and bzlan = benzylamine, has been synthesized and characterized by elemental analyses, IR, UV-Vis, and 1H NMR spectroscopy. The structure of this complex has been determined by X-ray crystallography. The Me2bpb2– is a di-anionic tetradentate ligand furnishing a ...

DNA sequence diversity in the tRNA(leu)-COII portion of the mitochondrial genome was investigated in samples of Apis cerana from Yunnan, China. A fragment of about 480 bp in tRNA(leu)-COII, including a noncoding area and part of COII, was sequenced. The noncoding area was 97-98 bp; 8 haplotypes were found, among which 5 had been reported previously, while 3 were new. The mean diversity of haplo...
