Changes in energy charge and block of protein synthesis in rabbit reticulocytes under the action of valinomycin.
Valinomycin blocks protein synthesis at the elongation stage in intact reticulocyte while being without action on a cell free system. We demonstrate here that this membrane mediated inhibition is acco...Read More
[Experimental evaluation of the toxicity and late effects of crown ethers at acceptable levels in water].
[Study of characteristics of the transplacental effects of formaldehyde and dicyclohexyl-18-crown-6 based on morphologic and biochemical indicators].
The synthesis, complexation properties and catalytic activities under phase-transfer (PT) conditions of differently substituted cyclohexapeptoids are reported. Association constants, for small cationi...Read More
Novel polysiloxane resin functionalized with dicyclohexano-18-crown-6 (DCH18C6): Synthesis, characterization and extraction of Sr(II) in high acidity HNO3 medium.
A novel kind of polysiloxane resin functionalized with dicyclohexano-18-crown-6 (DCH18C6) was synthesized through a post-modification approach. The DCH18C6 moieties bearing amino groups were firstly p...Read More
A molecularly imprinted polymer (MIP) comprising dicyclohexano-18-crown-6 (DCH18C6) was synthesized as a Sr-selective sorbent for urine bioassay purposes. MIP particles (326 ± 2 nm diameter) were for...Read More
Ultra-Trace Determination of Lead(II) in Water Using Electrothermal Atomic Absorption Spectrometry after Preconcentration by Solid-Phase Extraction to a Small Piece of Cellulose Acetate Type Membrane Filter.
A simple and inexpensive preconcentration technique has been developed for the ultra-trace determination of lead(II) using electrothermal atomic absorption spectrometry (ETAAS). The lead(II) complex w...Read More
Extraction and separation of a lysine-rich protein by formation of supramolecule between crown ether and protein in aqueous two-phase system
The macrocyclic calixarenes and crown ethers have recently been found to form hydrophobic complexes with the cationic protein cytochrome c (Cyt-c), by recognizing lysine residues on the protein surfac...Read More
Experimental and theoretical investigation of isotope fractionation of zinc between aqua, chloro, and macrocyclic complexes.
This work reports on the chemical isotope fractionation of Zn(II) by a solvent extraction method with the crown ether dicyclohexano-18-crown-6. The (m)Zn/(64)Zn ratios (m = 66, 67, and 68) were analyz...Read More
Preconcentration of thallium (I) by single drop microextraction with electrothermal atomic absorption spectroscopy detection using dicyclohexano-18-crown-6 as extractant system
A simple single drop liquid-phase microextraction (SDME) technique, combined with electrothermal atomic absorption spectroscopy (ETAAS) is developed both to preconcentrate and determine thallium (I) i...Read More
The effects of some potassium channel blockers on the ionic currents and on the so-called K(+)-depolarization in intact myelinated nerve fibres were studied. 4-AP, and in particular, Flaxedil, proved ...Read More
Solvent extraction of amino acids into a room temperature ionic liquid with dicyclohexano-18-crown-6.
Amino acids Trp, Gly, Ala, Leu are extracted efficiently from aqueous solution at pH 1.5-4.0 (Lys and Arg at pH 1.5-5.5) into the room temperature ionic liquid 1-butyl-3-methylimidazolium hexafluoroph...Read More
Could LogP be a principal determinant of biological activity in 18-crown-6 ethers? Synthesis of biologically active adamantane-substituted diaza-crowns
18-crown-6 ethers are known to exert their biological activity by transporting K^+ ions across cell membranes. Using non-linear Support Vector Machines regression, we searched for structural features ...Read More
