Cross‐Coupling Modification of Nucleoside Triphosphates, PEX, and PCR Construction of Base‐Modified DNA
Authors: Macickova‐Cahová Hana , Vrábel Milan , Hocek Michal
Published: February 2010

A novel, efficient, two‐step methodology is presented for construction of base‐modified oligonucleotides or DNA, involving aqueous cross‐coupling reactions of halogenated nucleoside triphosphates (dNTPs) with terminal acetylenes or arylboronic acids, followed by polymerase incorporation of the modified dNTPs either using primer extension (PEX) or polymerase chain reaction (PCR).

Published: February 2010

Mapping kinase‐substrate interactions demands robust methods to rapidly and unequivocally identify substrates from complex protein mixtures. Toward this goal, we present a method in which a kinase, engineered to utilize synthetic ATPγS analogs, specifically thiophosphorylates its substrates in a complex lysate. The thiophosphate label provides a bio‐orthogonal tag that can be used to affinity purify and identify labeled proteins. Following the labeling reaction, proteins are digested with trypsin; thiol‐containing peptides are then covalently captured and non‐thiol‐containing peptides are washed from the resin. Oxidation‐promoted hydrolysis, at sites of thiophosphorylation, releases phosphopeptides for analysis by tandem mass spectrometry. By incorporating two specificity gates—kinase engineering and peptide affinity purification—this method yields high‐confidence substrate identifications. This method gives both the identity of the substrates and phosphorylation‐site localization. With this information, investigators can analyze the biological significance of the phosphorylation mark immediately following confirmation of the kinase‐substrate relationship. Here, we provide an optimized version of this technique to further enable widespread utilization of this technology. Curr. Protoc. Chem Biol. 2:15‐36. © 2010 by John Wiley & Sons, Inc.
Cadmium‐induced increase in uterine wet weight and its mechanism
Authors: Liu Jin , Huang Huiling , Zhang Wenchang , Li Hong
Published: February 2010

BACKGROUND: Cadmium (Cd) increases in uterine wet weight in rodents remain unclear and there are only a few studies that examined the effects of Cd on uterine morphology. It is unknown whether Cd induces a uterotrophic effect via its interaction with the estrogen receptor (ER). In our study, we compared the effects of cadmium chloride (CaCl2) on uterine wet weight and morphology to those of 17β‐estradiol in Sprague‐Dawley (SD) rats. METHODS: Forty‐eight SD rats (23 days of age) were ectomized and randomly divided into six groups (eight rats per group): vehicle control (sterile saline solution), positive control (17β‐estradiol, 0.03 mg/kg in peanut oil), and CaCl2 groups (0.0064, 0.032, 0.16, and 0.8 mg/kg, respectively). The animals were treated by daily intraperitoneal (i.p.) injection for 3 days. The uteri were removed and assessed for weight, morphology, and immunohistochemical analysis. RESULTS: Compared to the control group, the uterine wet weight, the thickness of endomerium, the thickness of the stroma and the nucleus/cytoplasm ratio in the 17β‐estradiol‐treated and 0.8 mg/kg‐day CaCl2‐treated groups changed (P<0.01 or P 0.05). The endometrial gland number, the uterine epithelial cell height, and the PCNA‐positive expression in 17β‐estradiol‐treated rats increased compared to that of the control (P<0.01), but not in the CaCl2 dose groups. CONCLUSIONS: These results indicate that cadmium may induce an increase in uterine wet weight. However, this effect is not similar to that caused by 17β‐estradiol, suggesting it is not via Ca‐ER interactions. Birth Defects Res (Part B) 89:43–49, 2010.© 2010 Wiley‐Liss, Inc.

Bioactive Compounds with Added Value Prepared from Terpenes Contained in Solid Wastes from the Olive Oil Industry
Authors: Parra Andres , Lopez Pilar E. , Garcia‐Granados Andres
Published: February 2010

Starting from solid wastes from two‐phase olive‐oil extraction, the pentacyclic triterpenes oleanolic acid and maslinic acid were isolated. These natural compounds were transformed into methyl olean‐12‐en‐28‐oate (5), which then was transformed into several seco‐C‐ring triterpene compounds by chemical and photolytic modifications. The triene seco‐products were fragmented through several oxidative procedures to produce, simultaneously, cis‐ and trans‐decalin derivatives, both potential synthons for bioactive compounds. The chemical behavior of the isolated fragments was investigated, and a suitable approach to several low‐molecular‐weight terpenes was performed. These are interesting processes for the value‐addition to solid waste from the olive‐oil industry.

A new sesquiterpene ester, tunetanin A (1), a new sesquiterpene coumarin, tunetacoumarin A (2), together with eight known compounds, i.e., coladin (3), coladonin (4), isosmarcandin (5), 13‐hydroxyfeselol (6), umbelliprenin (7) propiophenone (8), β‐sitosterol (9), and stigmasterol (10), were isolated from the roots of Ferula tunetana. Their structures were elucidated on the basis of extensive spectroscopic methods, including 1D‐ and 2D‐NMR experiments and MS analysis, as well as by comparison with published data. The cytotoxicity of compounds 1–7 towards two human colon cancer cell lines, HT‐29 and HCT 116, was evaluated. Compounds 3, 4, and 6 showed weak cytotoxic activities.
Inhibition of Lipopolysaccharide‐Induced Nitric Oxide Production by Antofine and Its Analogues in RAW 264.7 Macrophage Cells
Authors: Min Hye‐Young , Song Su‐Hyun , Lee Boeun , Kim Sanghee , Lee Sang Kook
Published: February 2010

Based on the anti‐inflammatory activity of phenanthroindolizidine alkaloids, the inhibitory effect of antofine and its analogues on lipopolysaccharide (LPS)‐induced nitric oxide (NO) production was examined, and structure–activity relationships are discussed. Antofine and several analogues suppressed NO production in LPS‐stimulated RAW 264.7 cells. The MeO group at C(2), and the bulkiness of the substituents at C(3) and C(6) in the phenanthrene ring might be critical for this effect. Besides, regulation of iNOS expression might be involved in the inhibitory effect of antofine on LPS‐induced NO production in macrophage cells.
A Reversible Dual‐Response Fluorescence Switch for the Detection of Multiple Analytes
Authors: Geng Junlong , Liu Ping , Liu Bianhua , Guan Guijian , Zhang Zhongping , Han Ming‐Yong
Published: February 2010

This paper reports a reversible dual fluorescence switch for the detection of a proton target and 2,4,6‐trinitrotoluene (TNT) with opposite‐response results, based on fluorophore derivatization of silica nanoparticles. Fluorescent silica nanoparticles were synthesized through modification of the surface with a nitrobenzoxadiazole (NBD) fluorophore and an organic amine to form a hybrid monolayer of fluorophores and amino ligands; the resultant nanoparticles showed different fluorescence responses to the proton target and TNT. Protonation of the amino ligands leads to fluorescence enhancement due to inhibition of photoinduced electron transfer (PET) between the amine and fluorophore. By contrast, addition of TNT results in fluorescence quenching because a fluorescence resonance energy transfer (FRET) happens between the NBD fluorophore and the formed TNT–amine complex. The fluorescence signal is reversible through washing with the proper solvents and the nanoparticles can be reused after centrifugal separation. Furthermore, these nanoparticles were assembled into chips on an etched silicon wafer for the detection of TNT and the proton target. The assembled chip can be used as a convenient indicator of herbicide (2,4‐dichlorophenoxyacetic acid) and TNT residues with the use of only 10 μL of sample. The simple NBD‐grafted silica nanoparticles reported here show a reversible signal and good assembly flexibility; thus, they can be applied in multianalyte detection.
Three‐Dimensional Antiferromagnetic Order of Single‐Chain Magnets: A New Approach to Design Molecule‐Based Magnets

Published: February 2010

Two one‐dimensional compounds composed of a 1:1 ratio of MnIII salen‐type complex and NiII oximato moiety with different counter anions, PF6− and BPh4−, were synthesized: [Mn(3,5‐Cl2saltmen)Ni(pao)2(phen)]PF6 (1) and [Mn(5‐Clsaltmen)Ni(pao)2(phen)]BPh4 (2), where 3,5‐Cl2saltmen2−=N,N′‐(1,1,2,2‐tetramethylethylene)bis(3,5‐dichlorosalicylideneiminate); 5‐Clsaltmen2−=N,N′‐(1,1,2,2‐tetramethylethylene)bis(5‐chlorosalicylideneiminate); pao−=pyridine‐2‐aldoximate; and phen=1,10‐phenanthroline. Single‐crystal X‐ray diffraction study was carried out for both compounds. In 1 and 2, the chain topology is very similar forming an alternating linear chain with a [‐MnIII‐ON‐NiII‐NO‐] repeating motif (where ‐ON‐ is the oximate bridge). The use of a bulky counteranion, such as BPh4−, located between the chains in 2 rather than PF6− in 1, successfully led to the magnetic isolation of the chains in 2. This minimization of the interchain interactions allows the study of the intrinsic magnetic properties of the chains present in 1 and 2. While 1 and 2 possess, as expected, very similar paramagnetic properties above 15 K, their ground state is antiferromagnetic below 9.4 K and paramagnetic down to 1.8 K, respectively. Nevertheless, both compounds exhibit a magnet‐type behavior at temperatures below 6 K. While for 2, the observed magnetism is well explained by a Single‐Chain Magnet (SCM) behavior, the magnet properties for 1 are induced by the presence in the material of SCM building units that order antiferromagnetically. By controlling both intra‐ and interchain magnetic interactions in this new [MnIIINiII] SCM system, a remarkable AF phase with a magnet‐type behavior has been stabilized in relation with the intrinsic SCM properties of the chains present in 1. This result suggests that the simultaneous enhancement of both intrachain (J) and interchain (J′) magnetic interactions (with keeping J ≫ J′), independently of the presence of AF phase might be an efficient route to design high temperature SCM‐based magnets.
Transcription of Chirality in the Organogel Systems Dictates the Enantiodifferentiating Photodimerization of Substituted Anthracene

Published: February 2010

An organogelator (G) that contains 2‐anthracenecarboxylic acid (2Ac) attached covalently to a gelator counterpart that consists of 3,4,5‐tris(n‐dodecan‐1‐yloxy)benzoic acid by means of a chiral amino alcohol linkage has been synthesized. G acts as an efficient gelator of organic solvents, including mixed solvents and chiral solvents. Photodimers isolated after the photoreaction of the gel samples display different degrees of stereoselectivity. In the gel state, the formation of head‐to‐head (h–h) photodimers is always favored over head‐to‐tail (h–t) photodimers. Enantiomeric excess (ee) values of the major h–h photodimers reached as high as −56 % in the case of the gels with enantiomeric glycidyl methyl ethers. Here, the solvent chirality is outweighed by the intrinsic chirality of the gelator molecule. The packing of the chromophore in the gel state has been characterized by the absorption and the emission behaviors and their variations during the course of gel‐to‐sol phase transition. Whereas for the hexane gel, emission intensity increases with an increase in temperature, other systems show a decrease in emission intensity. Redshift of the λmax in the gel spectra indicates the J‐aggregate arrangement of the chromophores. Chiral transcription in the gel state has been investigated by CD spectroscopy, which shows a decrease in CD intensity during the gel‐to‐sol phase transition. The X‐ray diffraction study clearly differentiates among the gels in terms of the order of molecular arrangements. The gel systems are categorized as strong, moderately strong, and weak, that originate from the cooperative or individual participations of intermolecular hydrogen‐bonding and π–π interactions, fine‐tuned by the solvent polarity and the gelation temperature. A simple model based on the experimental findings and the molecular preorientation as evidenced by the stereochemistry of the photodimers has been proposed.
Stereoselective Triplet‐Sensitised Radical Reactions of Furanone Derivatives

Published: February 2010

The stereo‐ and regioselectivity of triplet‐sensitised radical reactions of furanone derivatives have been investigated. Furanones 7 a,b were excited to the 3ππ* state by triplet energy transfer from acetone. Intramolecular hydrogen abstraction then occurred such that hydrogen was transferred from the tetrahydropyran to the β position of the furanone moiety. Radical combination of the tetrahydropyranyl and the oxoallyl radicals led to the final products 8 a,b. In the intramolecular reaction, overall, a pyranyl group adds to the α position of the furanone. The effect of conformation was first investigated with compounds 9 a,b carrying an additional substituent on the tether between the furanone and pyranyl moiety. Further information on the effect of conformation and the relative configuration at the pyranyl anomeric centre and the furanone moiety was obtained from the transformations of the glucose derivatives 12, 14, 17 and 18. Radical abstraction occurred at the anomeric centre and at the 5′‐position of the glucosyl moiety. Computational studies of the hydrogen‐abstraction step were carried out with model structures. The activation barriers of this step for different stereoisomers and the abstraction at the anomeric centre and at the 6‘‐position of the tetrahydropyranyl moiety were calculated. The results of this investigation are in accordance with experimental observations. Furthermore, they reveal that the reactivity and regioselectivity are mainly determined in the hydrogen‐abstraction step. Intramolecular hydrogen abstraction (almost simultaneous electron and proton transfer) in 3ππ* excited furanones only takes place under restricted structural conditions in a limited number of conformations that are defined by the relative configuration of the substrates. It is observed that in the biradical intermediate, back‐hydrogen transfer occurs leading to the starting compound. In the case of glucose derivatives, this reaction led to epimerisation at the anomeric centre.
