Duerre, John A. (University of North Dakota, Grand Forks), and Chris H. Miller. Cleavage of S-ribosyl-l-homocysteine by extracts from Escherichia coli. J. Bacteriol. 91:1210-1217. 1966.-Cell-free extracts prepared from Escherichia coli catalyze the cleavage of the thioether linkage of S-ribosylhomocysteine. One of the products has been identified as homocysteine by paper chromatography of the N...

A homologous series of methylene- and thioether-linked cyanobiphenyl-based liquid crystal dimers, CBnSCB, was developed found to exhibit stable twist-bend nematic (NTB) phases, which undergo vitrification give NTB glass phases.

A series of thioether-functionalised imidazolium salts have been prepared and characterized. Subsequent reaction of the thioether-functionalised imidazolium salts with iodomethane affords imidazolium-sulfonium salts composed of doubly charged cations and two different anions. Imidazolium-sulfonium salts containing a single anion type are obtained either by a solvent extraction method or by anio...

Several N-functionalized bis(phosphino)amine ligands with ether, thioether and pyridyl tethers [(R'')2PN(R')P(R'')2=PNP] () have been synthesized. They react with CrCl3(THF)3 in CH2Cl2 to give dinuclear chloro bridged Cr2(micro-Cl)2Cl4(PNP)2 () which converts to the corresponding mononuclear solvento complexes fac-CrCl3(PNP)(NCR) (). The structures of the ligand with R'=-(CH2)3SCH3 and R''=Ph, ...

As a kind of promising drug carriers, smart polymers have attracted much attention due to the effective and controlled release in target cells. Herein, reactive oxygen species (ROS)-responsive thioether-containing amphiphilic hyperbranched polymer prepared from MTPA TMPTGE (HBPMT) is synthesized 3-(methylthio)propylamine (MTPA) trimethylolpropane triglycidyl ether (TMPTGE) by amine-epoxy click ...

The thioether-functionalized aminosilanes Me2Si(NH-C6H4-2-SR)2 (R=Ph, Me) were lithiated with n-BuLi and subsequently allowed to react CuCl in the presence of PMe3. In case Me2Si(NH-C6H4-2-SPh)2, dinuclear complex [Cu2{Me2Si(NC6H4-2-SPh)2}(PMe3)2] was isolated. copper atoms adopt a distorted trigonal-planar coordination (Cu−N: 191.2(2) pm, Cu−P: 216.3(1) Cu−S: 244.4(1) pm). reaction Li2Me2Si(N-...

Many biologically active peptides found in nature exhibit a bicyclic structure wherein a head-to-tail cyclic backbone is further constrained by an intramolecular linkage connecting two side chains of the peptide. Accordingly, methods to access macrocyclic peptides sharing this overall topology could be of significant value toward the discovery of new functional entities and bioactive compounds....

Current interest in copper/dioxygen reactivity includes the influence of thioether sulfur ligation, as it concerns the formation, structures, and properties of derived copper-dioxygen complexes. Here, we report on the chemistry of {L-Cu}2-(O2) species L = ESE, ESP, and ESDP, which are N3S(thioether)-based ligands varied in the nature of a substituent on the S atom, along with a related N3O(ethe...
