Gold(III) complexes containing N-heterocyclic carbene ligands: Thiol “switch-on” fluorescent probes and anti-cancer agents

Illuminating results: Activation of non-emissive [AuIII(N N N)(NHC)]+ complexes (such as 1) through reduction by intracellular glutathione gives active AuI-NHC complexes, which show promising anti-cancer properties, accompanied by release of the highly fluorescent ligand. The high fluorescence “switch-on” efficiency makes these Au III complexes excellent probes for cellular thiol detection. Copyright

Molybdenum and tungsten eta2-alkyne-1-thio complexes acting as sulfur donors in homoleptic werner type complexes with nickel(II) and palladium(II)

Facile access to the eta2-alkyne-1-thio complexes [Tp?M(CO)2{eta2-(BnS)CC(S)}] (Tp? = hydrotris(3,5-dimethylpyrazolyl)-borate; Bn = benzyl; M = Mo, W) by reductive removal of one benzyl group in the corresponding bis(benzylthio)-acetylene complexes, [Tp?M(CO)2{eta2-(BnS)CC(SBn)}](PF 6), has been thoroughly investigated. Experimental evidence of the intermediates, [Tp?M(CO)2{eta2-(BnS)CC(SBn)}] (M = Mo, W), and the fate of the cleaved benzyl group by isolation of the byproduct, [Tp?W(CO){C(O)Bn}{eta2-(BnS)CC(SBn)}], is provided. Neutral eta2-alkyne-1-thio complexes [Tp?M(CO)2{eta 2-(BnS)CC(S)}] bearing a free terminal sulfur atom have been established as monodentate ligands L in homoleptic pentanuclear [M?L 4]2+ complexes with nickel(II) and palladium(II). Comparison of the NMR and IR spectroscopic as well as cyclovoltammetric data of the heterobimetallic complexes with the free thio-alkyne complexes reveals a strong electronic coupling of the redox-active eta2-CC-bound metal centers and the sulfur-coordinated metal ion.

Identification of potent tricyclic prodrug S1P1 receptor modulators

Recently, our research group reported the identification of prodrug amino-alcohol 2 as a potent and efficacious S1P1 receptor modulator. This molecule is differentiated preclinically over the marketed drug fingolimod (Gilenya 1), whose active phosphate metabolite is an S1P1 full agonist, in terms of pulmonary and cardiovascular safety. S1P1 partial agonist 2, however, has a long half-life in rodents and was projected to have a long half-life in humans. The purpose of this communication is to disclose highly potent partial agonists of S1P1 with shorter half-lives relative to the clinical compound 2. PK/PD relationships as well as their preclinical pulmonary and cardiovascular safety assessment are discussed.

Blue-to-transmissive electrochromic switching of solution processable donor-acceptor polymers

The electrochromic performance of poly[2,3-bis-(3-octyloxyphenyl) quinoxaline-5,8-diyl-alt-thiophene-2,5-diyl] (TQ1), switching from an intense blue color to a transmissive yellow-brown oxidized state, are presented. Additionally, two new polymers, based on the same polymeric backbone but with oligoethylene oxide (TQ2) and ethylhexyloxy (TQ3) side chains, were prepared to compare the structure-property relationships. TQ1 has the highest optical contrast, with a transmittance change of 50%, recorded by spectroelectrochemistry at the low-energy absorption maximum (623 nm). The high optical contrast, facile synthetic preparation, and processability through good solubility in organic solvents make TQ1 an interesting polymer for implementation in non-emissive electrochromic devices. Response times were improved by the introduction of ethylhexyloxy side chains (TQ3), where 92% of the transmittance modulation was maintained at switching times of 0.5 s. The influence of film thickness on optical contrast was also investigated, where the highest optical contrast for TQ1 was obtained for films having reduced absorption of 0.84 a.u. at the low-energy absorption maximum. All three polymers show decent electrochemical stability over 200 full switches.
