The asymmetric unit of the title compound, C(7)H(3)F(4)NO(2), obtained as an inter-mediate in the synthesis of a coupling reagent, contains four independent and conformationally similar mol-ecules. The amine H atoms form both intra-molecular and inter-molecular N-H⋯O(carbox-yl) hydrogen bonds which, together with inter-molecular O-H⋯O(carbox-yl) hydrogen bonds and N-H⋯F associations form ribbon...

We have found CueO from Escherichia coli to have a robust cuprous oxidase activity, severalfold higher than any homologue. These data suggest that a functional role for CueO in protecting against copper toxicity in vivo includes the removal of Cu(I).

A one-step synthesis of water soluble and pH-responsive trypsin-stabilized fluorescent copper nanoclusters (CuNCs) was reported without using additional protective or reducing agents, and the as-prepared CuNCs exhibited highly stable properties including oxidation resistance, thermal stability and photostability.

Liquid or low melting association products of carbon dioxide and a secondary amine, both neutral molecules that may be gaseous, are recognised as "distillable" ionic media.

The structure and properties of diethanolamine complexes of copper(ii) triflates dissolved in an excess of diethanolamine (DH2) were studied. The copper containing substance was found to be a solution of copper(ii) complex salt [Cu(2+)DH2(DH(-))]OTf(-) in LTTM composition [(DH2)4H(+)](OTf(-)), where LTTM = low-transition-temperature mixture, OTf(-) = triflate anion. According to the EXAFS data,...

The use of data mining techniques in the field of nanomedicine has been very limited. In this paper we demonstrate that data mining techniques can be used for the development of predictive models of the cytotoxicity of poly(amido amine) (PAMAM) dendrimers using their chemical and structural properties. We present predictive models developed using 103 PAMAM dendrimer cytotoxicity values that wer...

N-Methyl-bis (3-mesyloxypropyl)amine hydrochloride is now in use as an antitumer drug. In view of its activity against some bacteria the present work was conducted to study its mode of action of Bacillus subtilis. The compound was found to induce irreversible damage to bacterial DNA whereas its effect on RNA was temporary and depending on maintenance of effective concentrations of the compound.

Weakly charged solid substrates can be nano-patterned in liquid-like order with large and well-defined spacing by adsorbing poly(amido amine) (PAMAM) dendrimers; highly charged substrates lead to lower spacing due to electrostatic three-body attractions between the dendrimers and the substrate.
