Modular chiral polyether podands and their lanthanide complexes

A novel tin-based imidazolium-modified montmorillonite catalyst for the preparation of poly(butylene terephthalate)-based nanocomposites using in situ entropically-driven ring-opening polymerization

A novel alkylimidazolium salt incorporating a 2,2-di-n-butyl[1,3,2]dioxastannolane moiety was synthesized and characterized.

Binding modes of reverse fosmidomycin analogs toward the antimalarial target IspC

1-Deoxy-d-xylulose 5-phosphate reductoisomerase of Plasmodium falciparum (PfIspC, PfDxr), believed to be the rate-limiting enzyme of the nonmevalonate pathway of isoprenoid biosynthesis (MEP pathway), is a clinically validated antimalarial target. The enzyme is efficiently inhibited by the natural product fosmidomycin. To gain new insights into the structure activity relationships of reverse fosmidomycin analogs, several reverse analogs of fosmidomycin were synthesized and biologically evaluated. The 4-methoxyphenyl substituted derivative 2c showed potent inhibition of PfIspC as well as of P. falciparum growth and was more than one order of magnitude more active than fosmidomycin. The binding modes of three new derivatives in complex with PfIspC, reduced nicotinamide adenine dinucleotide phosphate, and Mg(2+) were determined by X-ray structure analysis. Notably, PfIspC selectively binds the S-enantiomers of the study compounds.

1,2-Diphenylethane-1,2-diyl diisonicotinate monohydrate

In the novel title compound, C₂₆H₂₀N₂O₄·H₂O, the two phenyl rings make a dihedral angle of 45.3 (1)° with each other, and the dihedral angle between the two pyridyl planes is 69.8 (1)°.

Responsive lanthanide luminescent cyclen complexes: from switching/sensing to supramolecular architectures

This article highlights some of the recent developments in the use of responsive cyclen based lanthanide luminescent devices, focusing on Eu(III), Tb(III), Nd(III) and Yb(III) complexes, where the photophysical properties, such as the excited state lifetimes, quantum yield/intensity and emission polarisation are modulated by the local chemical environment, e.g. ions and molecules, or through self-assembly of either f-f or mixed f-d cyclen complexes.
