          Abstract

          A series of complexes of the type [Cu(X)(NHC)] (X = I, Br, Cl, NHC = N-heterocyclic carbene) was synthesised using a one-pot, mild and user-friendly (aerobic, tech. grade solvents) procedure.

          Abstract

          A one-pot procedure for the synthesis of [Cu(X)(NHC)] (X = Cl, Br, I) is reported. The reaction is applicable to a wide range of saturated and unsaturated NHC ligands, is scalable and proceeds under mild conditions using technical grade solvents in air.

          Metal N-heterocyclic carbene complexes as potential antitumor metallodrugs.

          The discovery of cisplatin's antitumor activity in 1969 prompted the search for novel metal-containing complexes as potential anticancer drugs. Among these novel complexes, metal N-heterocyclic carbene (NHC) complexes have recently gained considerable attention because they perfectly fit prerequisites for efficient drug design and fast optimization. Moreover, most of them have shown higher cytotoxicity than cisplatin. This review describes the advances that have been achieved in using transition metal (Ag, Au, Pt, Pd, Cu, Ni, and Ru) complexes containing NHC ligands as antitumor agents. Their modes of action at the cellular lever are further discussed. All these initial achievements clearly demonstrate the great potential of metal-NHC complexes as antitumor agents.

            Design and properties of functional nanotubes from the self-assembly of cyclic peptide templates.

            β-Sheet forming self assembling cyclic peptides offer a versatile scaffold for the construction and control of hydrogen-bonded nanotube assemblies. These structures have major advantages over other nanoscale tubular structures, including sub-nanometer control over the internal diameter, and the ability to control internal and external chemical functionality. This Tutorial Review presents an overview of nanotubes derived from this class of cyclic peptides. The design rationale for functional nanotubes based on cyclic peptide ring size and chemical functionality is discussed. Additionally, we highlight the recent expansion of the nanotube toolbox through conjugation of (macro)molecules to the cyclic peptides. These provide additional functionality and control nanotube dimensions that could potentially prove beneficial in future applications.
