Identification and characterization of novel benzil (diphenylethane-1,2-dione) analogues as inhibitors of mammalian carboxylesterases.
J. Med. Chem. 48 , 2906-15, (2005) Carboxylesterases (CE) are ubiquitous enzymes responsible for the metabolism of xenobiotics. Because the structural and amino acid homology among esterases of different classes, the identification of selective inhibitors of these proteins has proved problemat... |

Influence of composition on rate of polymerization contraction of light-curing resin composites.
Acta Odontol. Scand. 60(3) , 146-50, (2002) A slow contraction may result in reduced gap formation when a restorative resin polymerizes in a dental cavity. It was the aim in the present work to investigate the rate of contraction in relation to composition of experimental light-curing resin composites.... |

Inhibition of the reconstituted mitochondrial oxoglutarate carrier by arginine-specific reagents.
Arch. Biochem. Biophys. 331(1) , 48-54, (1996) The effect of arginine-specific reagents on the function of the purified and reconstituted oxoglutarate carrier protein of the inner mitochondrial membrane has been investigated. The alpha-dicarbonyl reagents 2,3-butanedione, 2,3-pentanedione, 2,3- and 3,4-he... |

A combined NMR, DFT, and X-ray investigation of some cinchona alkaloid O-ethers.
J. Org. Chem. 73(17) , 6559-69, (2008) Structures and conformational behavior of several cinchona alkaloid O-ethers in the solid state (X-ray), in solution (NMR and DFT), and in the gas phase (DFT) were investigated. In the crystal, O-phenylcinchonidine adopts the Open(3) conformation similar to c... |
