MAF amplification licenses ERα through epigenetic remodelling to drive breast cancer metastasis.
MAF amplification increases the risk of breast cancer (BCa) metastasis through mechanisms that are still poorly understood yet have important clinical implications. Oestrogen-receptor-positive (ER+) BCa requires oestrogen ...
Behaviour of Pt/TiO2 catalysts with different morphological and structural characteristics in the photocatalytic conversion of ethanol aqueous solutions
Pt/TiO2 catalysts with a similar Pt dispersion and different morphological and structural characteristics were prepared, characterized and used in the photocatalytic transformation of aqueous ethanol solutions at room ...

Cyclometallated Imides as Templates for the H-Bond Directed Iridium-Catalyzed Asymmetric Hydrogenation of N-Methyl, N-Alkyl and N-Aryl Imines.
A combined computational and experimental approach allowed us to develop overall the most selective catalyst for the direct hydrogenation of N-methyl, N-alkyl and N-aryl imines described to date. Iridium catalysts with a ...

Lanthanide molecules for spin-based quantum technologies
Since the molecular electronic spin emerged as one of the promising technologies to implement the quantum processing of information, coordination complexes of lanthanides and actinides have become protagonists as suitable ...
Three valuable peptides from bee and wasp venoms for therapeutic and biotechnological use: melittin, apamin and mastoparan
While knowledge of the composition and mode of action of bee and wasp venoms dates back 50 years, the therapeutic value of these toxins remains relatively unexploded. The properties of these venoms are now being studied ...
Kinetico-Mechanistic Studies on a Reactive Organocopper(II) Complex: Cu−C Bond Homolysis versus Heterolysis
Organocopper(II) reagents are an unexplored frontier of copper catalysis. Despite being proposed as reactive intermediates, an understanding of the stability and reactivity of the CuII-C bond has remained elusive. Two main ...
An algorithm to find the optimal oriented external electrostatic field for annihilating a reaction barrier in a polarizable molecular system
The use of oriented external electric fields (OEEFs) to promote and control chemical reactivity has motivated many theoretical and computational studies in the last decade to model the action of OEEFs on a molecular system ...
Tandem Mn-I Exchange and Homocoupling Processes Mediated by a Synergistically Operative Lithium Manganate
Pairing lithium and manganese(II) to form lithium manganate [Li2Mn(CH2SiMe3)4] enables the efficient direct Mn-I exchange of aryliodides, affording transient (aryl)lithium manganate intermediates which in turn undergo ...
Spacer-free BODIPY fluorogens in antimicrobial peptides for direct imaging of fungal infection in human tissue
Fluorescent antimicrobial peptides are promising structures for in situ, real-time imaging of fungal infection. Here we report a fluorogenic probe to image Aspergillus fumigatus directly in human pulmonary tissue. We have ...
Octanuclear Ni4Ln4 coordination aggregates from Schiff Base anion supports and connecting of two Ni2Ln2 cubes: syntheses, structures, and magnetic properties
A family of 3d-4f aggregates have been reported through guiding the dual coordination modes of ligand anion (HL−) and in situ generated ancillary bridge driven self-assembly coordination responses toward two different types ...
Exploiting protected maleimides to modify oligonucleotides, peptides and peptide nucleic acids
This manuscript reviews the possibilities offered by 2,5-dimethylfuran-protected maleimides. Suitably derivatized building blocks incorporating the exo Diels-Alder cycloadduct can be introduced at any position of ...
5-Phenyl-10,15,20-tris(4-sulfonatophenyl)porphyrin: Synthesis, catalysis and structural studies
A convenient protocol for the preparation of 5-phenyl-10,15,20-tris(4-sulfonatophenyl) porphyrin, a water-soluble porphyrin with unique aggregation properties, is described. The procedure relies on the one-pot reductive ...
Lanthanide chain assembled in metal-organic frameworks: slow relaxation of the magnetization in Dy (III) and Er (III) complexes
Three new LnIII-MOFs, {[Dy1.5(TAPB)1.5(DMF)]·9DMF}n (Ln = Dy (1), Er (2), Ho (3); TAPB = 4, 4′, 4″-(triazine‑2, 4, 6‑triyl‑tris‑(benzene‑4, 1-diyl)) tribenzoate), have been synthesized via a solvothermal method by using a ...
Strengthened cooperativity of DNA-based cyclic hydrogen-bonded rosettes by subtle functionalization
Cooperative effects cause extra stabilization of hydrogen-bonded supramolecular systems. In this work we have designed hydrogen-bonded rosettes derived from a guanine–cytosine Janus-type motif with the aim of finding a ...
Single-molecule transport of fullerene-based curcuminoids
We present experimental and theoretical studies of single-molecule conductance through nonplanar fullerocurcuminoid molecular dyads in ambient conditions using the mechanically controllable break junction technique. We ...
Aggregation of gold(I) complexes: phosphorescence vs. singlet oxygen production
Herein we report on the synthesis of six new phosphane-gold(I)-4-ethynylaniline complexes (neutral and cationic), with a tris-naphthalene substituted tertiary phosphane bearing a secondary amine as a linker and containing ...
