Angew. Chem. Int. Ed. [BCB]

Abstract: Copper-complexes are of medicinal and biological interest, including as anticancer drugs designed to cleave intracellular biomolecules via O2 activation. To exhibit such activity, the copper complex must be redox-active and resistant to dissociation. Metallothioneins (MTs) and glutathione (GSH) are abundant in the cytosol and nucleus. Because they also are thiol-rich reducing molecules...[more]

Chemistry Eur. J. [CBAT/RMN]

Abstract: IspH/LytB, an oxygen‐sensitive [4Fe‐4S] enzyme, catalyzes the last step of the methylerythritol phosphate (MEP) pathway, a target for the development of new antimicrobial agents. This metalloenzyme converts (E)‐4‐hydroxy‐3‐methylbut‐2‐en‐1‐yl diphosphate (HMBPP) into the two isoprenoid precursors: isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP). Here, the synthesis...[more]

J. Mat. Chem. C [LECPCS]

Abstract: A series of three new polyoxometalate/spiromolecule compounds – including the (TBA)3[AlMo6-SN] (SN = spironaphthoxazine) and (TBA)3[AlMo6-SP] (SP = spiropyran) Anderson-type polyoxometalates (POMs) and the unprecedented (TBA)5[P2W15V3-SP] Dawson-type species – has been synthesized and characterized using a full panel of techniques. These hybrids have been thoroughly investigated by...[more]

Chemistry Eur. J. [BCB /POMAM]

Abstract: Mounting evidence supports the role of amyloidogenesis, oxidative stress, and metal dyshomeostasis in the development of neurodegenerative disorders. Parkinson's Disease is characterized by α-Synuclein (αSyn) accumulation and aggregation in brain regions, also promoted by Cu2+. αSyn is modified by reactive carbonyl species, including acrolein (ACR). Notwithstanding these findings, the...[more]

Organic Geochemistry [Biogéochimie moléculaire]

Abstract: The widely distributed aromatic di- and triterpenoids from higher plants occurring in sediments are formed by diagenetic microbial processes affecting their precursor plant lipids. These compounds and their stable isotopic composition (δ13C and δ2H) have the potential to be used for palaeoenvironmental and palaeoclimatic studies. In the present study, the isotopic composition of di-...[more]

Organic Geochemistry [Biogéochimie moléculaire]

Abstract: Birch bark tar, an organic material frequently encountered during archaeological excavations, has been identified from its lipid composition on the cracks of a ceramic dated to the late Neolithic. Lipids of this black substance were dominated by a characteristic triterpenoid assemblage of lupane-related triterpenoids from birch bark, together with their thermal degradation products...[more]
