Published: April 2006

AbstractThe aims of this study were to analyze flavin‐containing monooxygenase3 (FMO3)polymorphisms and allele and genotype frequencies in 256 Han Chinese and 50 African‐American individuals, to compare the allele and genotype frequencies of these populations with those of other world populations. For Han Chinese, genotyping of three common single nucleotide polymorphisms, E158K, V257M and E308G was performed by polymerase chain reaction‐restriction fragment length polymorphism (PCR‐RFLP). For African‐Americans, genotyping of all coding exons was performed by modified PCR‐single strand conformational polymorphism (SSCP). Evolutionary rates ofFMO3were estimated computationally. We found that there were significant differences in allele and genotype frequencies among Han Chinese, African‐Americans and other world populations. In Han Chinese, the minor allele frequencies (MAFs) were 0.229 (E158K), 0.203 (V257M) and 0.148 (E308G), respectively. In African‐Americans, MAFs were 0.48 (E158K), 0.05 (V257M) and 0 (E308G), respectively. There was rapid evolution during the divergence of primateFMO3. This is the first report comparingFMOalleles and genotypes between Han Chinese and African‐Americans. A Han Chinese population database has been established for three gene polymorphisms. The data presented here justify further pharmacogenetic studies for potentially optimizing recommended drug dosages and evaluating relationships with disease processes.

Catheter management of aortic valve stenosis in neonates and children
Authors: Weber Howard S. 
Published: April 2006

AbstractTherapy for severe aortic valve stenosis in infants and children has shifted from the operating suite to the catheterization laboratory and even to the bedside as a direct result of improved catheter technology, evolving techniques, and comparable results to conventional surgical intervention. This review summarizes the brief history pertaining to the various techniques and outcomes of transcatheter balloon valvuloplasty in infants and children with critical or severe aortic valve stenosis. © 2006 Wiley‐Liss, Inc.
One‐Pot Enantioselective Aziridination of Olefins Catalyzed by a Copper(I) Complex of a Novel Diimine Ligand by Using PhI(OAc)2 and Sulfonamide as Nitrene Precursors
Authors: Wang Xisheng , Ding Kuiling 
Published: April 2006

AbstractA novel chiral C2‐symmetric 1,4‐diamine with multistereogenic centers at the backbone of the ligand has been synthesized from cheap natural product D‐mannitol through multistep transformations. Its diimine derivative (3 a) was found to be highly effective for the enantioselective control of the copper‐catalyzed asymmetric aziridination of olefin derivatives with PhINTs as the nitrene source, affording the corresponding N‐sulfonylated azirindine derivatives in good to excellent yields with up to 99 % ee (ee=enantiomeric excess). The catalyst system discovered in the present work was also extended to a one‐pot enantioselective aziridination by using sulfonamide/iodobenzene diacetate as the nitrene source. In this case, most reactions proceeded smoothly to give the corresponding products in moderate yields with good to excellent enantiomeric excesses (75–96 % ee).
Photosensitized Oxidation of Sulfides: Discriminating between the Singlet‐Oxygen Mechanism and Electron Transfer Involving Superoxide Anion or Molecular Oxygen

Published: April 2006

AbstractThe oxidation of diethyl and diphenyl sulfide photosensitized by dicyanoanthracene (DCA), N‐methylquinolinium tetrafluoroborate (NMQ+), and triphenylpyrylium tetrafluoroborate (TPP+) has been explored by steady‐state and laser flash photolysis studies in acetonitrile, methanol, and 1,2‐dichloroethane. In the Et2S/DCA system sulfide‐enhanced intersystem crossing leads to generation of 1O2, which eventually gives the sulfoxide via a persulfoxide; this mechanism plays no role with Ph2S, though enhanced formation of 3DCA has been demonstrated. In all other cases an electron‐transfer (ET) mechanism is involved. Electron‐transfer sulfoxidation occurs with efficiency essentially independent of the sulfide structure, is subject to quenching by benzoquinone, and does not lead to Ph2SO cooxidation. Formation of the radical cations R2S.+ has been assessed by flash photolysis (medium‐dependent yield, dichloroethane≫CH3CN>CH3OH) and confirmed by quenching with 1,4‐dimethoxybenzene. Electron‐transfer oxidations occur both when the superoxide anion is generated by the reduced sensitizer (DCA.−, NMQ.) and when this is not the case (TPP.). Although it is possible that different mechanisms operate with different ET sensitizers, a plausible unitary mechanism can be proposed. This considers that reaction between R2S.+ and O2.− mainly involves back electron transfer, whereas sulfoxidation results primarily from the reaction of the sulfide radical cation with molecular oxygen. Calculations indeed show that the initially formed fleeting complex RS2+⋅⋅⋅OO. adds to a sulfide molecule and gives strongly stabilized R2SO.+OSR2 via an accessible transition state. This intermediate gives the sulfoxide, probably via a radical cation chain path. This mechanism explains the larger scope of ET sulfoxidation with respect to the singlet‐oxygen process.
Controlled Assembly of a Heterogeneous Single‐Site Ethylene Trimerization Catalyst as Probed by X‐ray Absorption Spectroscopy

Published: April 2006

AbstractX‐ray absorption spectroscopy at the Cr K‐ and L2,3‐edges was used to study the assembling process of a heterogeneous Cr‐based single‐site catalyst. The starting point was a Phillips‐type system with monochromate species anchored on a silica surface, which was first reduced to a variety of different surface CrII species. The reduced sample was modified with a 1,3,5‐tribenzylhexahydro 1,3,5‐triazine (TAC) ligand in the presence of CH2Cl2 as solvent to yield a heterogeneous single‐site Cr‐based catalyst active in the trimerization of ethylene. The molecular structure of the resultant catalytic material consists of distorted octahedral CrIII species. The extended X‐ray absorption fine‐structure (EXAFS) spectroscopy fitting procedure in R space up to 2.5 Å showed that the synthesis leads to coordination with a TAC ligand. The fit also shows that it was possible to complete the six‐fold environment around CrIII with two oxygen atoms and one chloride ligand. This chloride ligand is formed in a redox process from the solvent and is responsible for the oxidation of surface CrII to CrIII. The obtained geometry and the local environment of the surface complex are discussed in light of its homogeneous counterpart and confirm the single‐site characteristics of the prepared catalytic material.
