  • Cyclization of Peptides by using Selenolanthionine Bridges
    作者:Aline Dantas de Araujo、Mehdi Mobli、Glenn F. King、Paul F. Alewood
    DOI:10.1002/anie.201204229
    日期:2012.10.8
    Selenocysteine does the job: Lanthionine bridges are important structural elements in naturally occurring lantibiotics. They can be engineered into peptides to increase biological activity and metabolic stability. Macrocyclization of peptides by intramolecular thiolation of cysteine is often difficult but can be achieved by replacing cysteine with the more reactive isosteric selenocysteine amino acid

Single-crystal X-ray analysis revealed that conformation isomerism of the ppcd ligand was associated with the configuration of −N–N– (trans or cis) and could induce the versatile coordination mode in the presence of different anions. The 1D chiral chain was interestingly obtained from the achiral rigid ligand in complex 2. Magnetic studies indicated

  • Tuning Transverse Anisotropy in Co<sup>III</sup>–Co<sup>II</sup>–Co<sup>III</sup> Mixed-Valence Complex toward Slow Magnetic Relaxation
    作者:Dayu Wu、Xingxing Zhang、Ping Huang、Wei Huang、Mingyue Ruan、Z. W. Ouyang
    DOI:10.1021/ic401057f
    日期:2013.10.7
    Two cobalt mixed-valence complexes with different substituents have been prepared and structurally characterized by single-crystal X-ray diffraction to alter slow magnetic relaxation by tailoring the transverse anisotropy. The trinuclear complexes [(L-1)(4)Co-3(H2O)(2)](NO3)(4)center dot CH3OH center dot 5H(2)O (1-NO3) and [(L-2)(4)Co-3(H2O)(2)](NO3)(4)center dot 6H(2)O (2-NO3) feature a distorted octahedral Co(II) strongly hindered in a trinuclear Co-III-Co-II-Co-III mixed-valence array. Detailed magnetic studies of 1-NO3 and 2-NO3 have been conducted using direct- and alternating-current magnetic susceptibility data. In accordance with variable-field magnetic susceptibility data at low temperatures, high-field electron paramagnetic resonance (HF-EPR) spectroscopy reveals the presence of an easy-plane anisotropy (D > 0) with a significant transverse component, E, in complexes 1-NO3 and 2-NO3. These findings indicate that the onset of the variation of distortion within complex 2-NO3 leads to a suppression of quantum tunneling of the magnetization within the easy plane, resulting in magnetic bistability and slow relaxation behavior. Consequently, the anisotropy energy scale associated with the relaxation barrier, 5.46 cm(-1) (tau(o) = 1.03 X 10(-5) s), is determined by the transverse E term. The results demonstrate that slow magnetic relaxation can be switched through optimization of the transverse anisotropy associated with magnetic ions that possess easy-plane anisotropy.
