- Recognition characteristics of molecularly imprinted microspheres for triazine herbicides using hydrogen-bond array strategy and their analytical applications for corn and soil samples.
- Wu S1, Xu Z, Yuan Q, Tang Y, Zuo X, Lai J.Author information 1School of Chemistry & Environment, South China Normal University, Guangzhou 510006, China.AbstractThe homogeneous molecularly imprinted microspheres (MIMs) based on a biologically inspired hydrogen-bond array were prepared using allobarbital as the novel functional monomer and divinylbenzene as the cross-linker. The host-guest binding characteristics were examined by molecular simulation and infrared spectroscopy. The resultant MIMs were evaluated using high performance liquid chromatography and solid-phase extraction. The results obtained demonstrate that the good imprinting effect and the excellent selectivity of MIMs are mainly due to the interaction involving the formation of three-point hydrogen bond between host and guest. The complete baseline separation was obtained for five triazine analogues and a metabolite on the MIM HPLC column. The MIMs were further successfully used as a specific sorbent for selective extraction of simetryne from corn and soil samples by molecularly imprinted solid phase extraction. Detection limits and recoveries were 5.8 μg/kg and 0.14 μg/kg and 87.4-105% and 94.6-101% for simetryne in corn and soil sample, respectively.

- [Studies on the structure-activity relationship of allyl substituted oxopyrimidines searching for the novel antagonist or agonist of barbiturates to the sleep mechanism based on the uridine receptor theory--barbituric acid to uridine (part I)].
- Yamamoto I.Author information Faculty of Pharmaceutical Sciences, Hokuriku University, Kanazawa 920-1181, Japan. iyamamoto@phoenix.ac.jpAbstractThirty-six allyl substituted oxopyrimidine analogues such as barbituric acid (BA), barbiturates, uracil, thymine, and related derivatives including 13 new compounds were synthesized and their pharmacologic effects ([hypnotic activity, anticonvulsant activity against pentylentetrazol (PTZ)-induced seizures, and LD(50)]) and interactions with the barbiturates were evaluated in mice and rats. The results are briefly and parially summarized as follows. BA prolonged pentobarbital (PB)-induced sleep and had some central depressant effects. N,5,5-triallyl-BA exhibited some hypnotic and anticonvulsant activities, although the other 5,N-allyl-compounds did not show any activity except for allobarbital (AlloB). N-allyl-BA, 5-allyl-BA, N(1),N(3),5-triallyl-BA, N,5,5-triallyl-BA, and N(1),N(3),5,5-tetraallyl-BA also prolonged PB-induced sleep. Interestingly, N,5,5-triallyl-BA was the most potent in the interaction with AlloB, phenobarbital (PheB), amobarbital (AB), PB, and thiopental (TP) but not barbital (B). N(1),N(3),5,5-tetraallyl-BA prolonged AlloB-, PB-, and AB-induced sleep but not B-, PheB-, and TP-induced sleep. N(1),N(3),5-triallyl-B prolonged only PB- and TP-induced sleep. 5,5-diallyl-BA prolonged PheB- and TP-induced sleep. N,5-diallyl-BA prolonged only TP-induced sleep. In contrast, BA and N(1),N(3),5-triallyl-AB tended to antagonize AlloB, AB, and B. N(1),N(3),5,5-tetraallyl-BA also slightly antagonized B, PheB, and TP. 5,5-diallyl-BA antagonized only AB. The prolonging effects of BA, N,5,5-triallyl-BA, and N(1),N(3),5,5-tetraallyl-BA on PB-induced sleep were dose dependent. These results indicate that the position and number of allyl groups substituted on the structure of BA play an important role in their depressant activities. This review deals with the structure-activity relationship of allyl-substituted oxopyrimidines as part of our search for antagonists and agonists of barbiturates as well as their mechanisms of action.

- Application of atmospheric pressure chemical ionisation mass spectrometry in the analysis of barbiturates by high-speed analytical countercurrent chromatography.
- Jones JJ1, Kidwell H, Games DE.Author information 1Mass Spectrometry Research Unit, University of Wales Swansea, Grove Building, Singleton Park, Swansea SA2 8PP, Wales, UK. 147437@swan.ac.ukAbstractFour barbiturates (barbital, allobarbital, phenobarbital and butalbital) were analysed using high-speed analytical countercurrent chromatography (HSACCC) and high-performance liquid chromatography (HPLC) interfaced with mass spectrometry, using negative mode atmospheric pressure chemical ionisation (APCI). The polar biphasic solvent system of butyronitrile/acetonitrile/water (1:1:1) was used, in the upper-stationary, lower-mobile mode of operation, at a flow rate of 1 mL/min and a rotational speed of 1200 rpm, equating to an applied "g"-field of 177 g. The fractional stationary phase retention (S(F)) was 0.58. Representative mass spectral data are presented from the HPLC and the HSACCC analyses. Structural information was obtained using source-induced fragmentation at increased source block voltages. The effect of increasing g-field on chromatographic resolution is illustrated using the binary base system of butyronitrile/water (1:1), under electrospray ionisation.
