“…A reverse synthetic strategy for wheel-and-axle (waa) systems takes into account bulky metal-containing units at the ends, while the central spacer can be constructed either by a bidentate divergent ligand granting a covalent rigid axle (covalent waa), or by a robust supramolecular synthon (supramolecular waa) (Scheme 1) occurring between suitable dimerizing functions present on an organic ligand bound to the metal [4].…”

“…11,42 Pyridine was selected as the coordinating moiety based on the widespread use of such ligands in the domain. [43][44][45][46][47][48][49][50][51] The uorous and alkyl chains are connected to the pyridine ligand via an ester linker that may, in principle, be hydrolysed by intracellular enzymes such as esterases. 41,52,53…”

Application of mild hyperthermia can increase the cytotoxicity of anticancer drugs in tumour cells. In this report, we describe low molecular weight thermoactive ruthenium-based drugs with fluorous chains that are selectively triggered by mild hyperthermia. The organometallic complexes were prepared, characterized, and evaluated for their in vitro cytotoxicity against a panel of human cancer cell lines and non-cancerous immortalized cells. The compounds show considerable chemo-thermal selectivity towards cancer cells (ca. 5 mM versus >500 mM for healthy cells) for the compound with the longest fluorous chain.

“…Two symmetry related water molecules are inserted in the NH⋯Cl-Ru cage (Fig. 6 Water is in fact a better hydrogen bond partner than alcohols, and therefore it associates with the best hydrogen bond donors (NH) and acceptors (Ru-Cl) 5,6 present in the organometallic building-block, while the amidic CO is not involved in the network.…”

“…In fact, the N-H bonds engage the hydrogen-bond acceptors, chloride ligands, 5 in intermolecular N-H⋯Cl-Ru hydrogen bonds, thus preventing their involvement in intermolecular Ru-Cl⋯H-OOC hydrogen bonds which would impede the creation of the desired supramolecular motif. 6 The clathrating properties of the isolated waa compounds are strongly dependent on the length of the supramolecular spacer which in turn dictates the roominess of the cavities present in the lattice, as demonstrated by the possibility of obtaining solvates only with 4-aminocinnamic acid. The complex containing 4ABA is instead completely insensitive to a number of different hydrogen-bond donor/acceptor solvents, such as methanol, THF, acetone and water.…”
