Abstract

A variety of neutral carrier type ionophores for monovalent cations were employed to prepare solid-state cation-selective electrodes (SSEs) for use as a detector in single-column ion chromatography (IC). The polyurethane-based pseudoreference electrode made it possible to assemble an array type SSE detector for IC. An SSE-based detector provides not only the overall chromatogram for the separated ion species (monensin methyl ester-nonactin-based membrane), but also the enhanced chromatogram for specified ions of interest (valinomycin as K+ and nonactin for NH4+). This feature makes it possible to perform highly quantitative analysis with low detection limits even if the separation efficiency of the ion-exchange is not sufficient. Since SSE-based IC detectors are easily miniaturized and replaceable at low cost, they are an ideal component of a portable IC system.

Cation-pi interactions and the gas-phase thermochemistry of the Na(+)/phenylalanine complex.

The complex of Na(+) with phenylalanine (Phe) is a prototype for the participation of cation-pi interactions in metal-ion binding to biological molecules. A recent comparison of this complex with the Na(+)/alanine (Na(+)/Ala) counterpart suggested only a small contribution of the phenyl ring interaction to binding, casting doubt on the extent of the cation-pi effect. The present work reexamines this thermochemistry using ligand-exchange equilibrium measurements in the Fourier transform ion cyclotron resonance (FT-ICR) ion trapping mass spectrometer. An increment of 7 +/- 2 kcal mol(-1) was found in the Ala/Phe comparison of binding enthalpies, confirming the importance of cation-pi binding enhancement in the Phe case. Absolute Na(+) binding enthalpies of 38 +/- 2 and 45 +/- 2 kcal mol(-1) were assigned for Ala and Phe, respectively, using pyridine as the thermochemical reference ligand. All of these results were supported by quantum calculations using both density functional and Hartree-Fock/MP2 methods, improved in several respects over previous calculations. Alanine methyl ester (AlaMe) was also observed, and found to have an Na(+) ion affinity larger by 2.3 kcal mol(-1) than Ala. New, lower energy conformations of neutral Phe were discovered in the computations.

Optimized analytical method for cyclosporin A by high-performance liquid chromatography-electrospray ionization mass spectrometry.

The Micromass Platform LCZ mass detector parameters were optimized for simultaneous recording of the protonated (CsA-H+), sodium adduct (CsA-Na+) and potassium adduct (CsA-K+) of cyclosporin A eluted from a Symmetry Shield RP8 column. The optimized procedure allows a precise analysis of CsA in whole blood or serum without removal of salts prior to analysis. The ratio of the three forms of CsA varied depending on the assay condition and the types of specimens being analyzed. The summation of three ionic forms of CsA detected by LC-ESI-MS is a reliable and simple method to assess CsA concentration in the blood.

Alkali metal cation-pi interactions observed by using a lariat ether model system.

The Na(+) or K(+) cation-pi interaction has been experimentally probed by using synthetic receptors that comprise diaza-18-crown-6 lariat ethers having ethylene sidearms attached to aromatic pi-donors. The side chains are 2-(3-indolyl)ethyl (7), 2-(3-(1-methyl)indolyl)ethyl (8), 2-(3-(5-methoxy)indolyl)ethyl (9), 2-(4-hydroxyphenyl)ethyl (10), 2-phenylethyl (11), 2-pentafluorophenylethyl (12), and 2-(1-naphthyl)ethyl (13). Solid-state structures are reported for six examples of alkali metal complexes in which the cation is pi-coordinated by phenyl, phenol, or indole. Indole-containing crown, 7, adopts a similar conformation when bound by NaI, KI, KSCN, or KPF(6). In each case, the macroring and both arenes coordinate the cation; the counteranion is excluded from the solvation sphere. NMR measurements in acetone-d(6) solution confirm the observed solid-state conformations of unbound 7 and 7.NaI. In 7.Na(+) and 7.K(+), the pyrrolo, rather than benzo, subunit of indole is the pi-donor for the alkali metal cation. Cation-pi complexes were also observed for 10.KI and11.KI. In these cases, the orientation of the cation on the aromatic ring is in accord with the binding site predicted by computational studies. In contrast to the phenyl case (11) the pentafluorophenyl group of 12 failed to coordinate K(+). Solid-state structures are also reported for 7.NaPF(6), 10.NaI, 11.NaI, 13.KI, 13.KPF(6), and 9.NaI, in which cation-pi complexation is not observed. Steric and electrostatic considerations in the pi-complexation of alkali metal cations by these lariat ethers are thought to account for the observed complexation behavior or lack thereof.
