Highly selective ensembles for D-fructose based on fluorescent method in aqueous solution

Three highly sensitive and selective switches for monosaccharides were composed by anionic polyelectrolyte PPPSO3Na and cationic viologen quencheres BBVs. The sensing processes of three ensembles (PPPSO 3Na/o-BBV, PPPSO3Na/m-BBV and PPPSO3Na/p-BBV) to common seven monosaccharides have been determined by fluorescence spectra at pH 7.4 buffer solution. The results show that the three sensing ensembles all embody higher selectivity and sensitivity for d-fructose with reversible “on-off-on” fluorescence response. The research results can provide a new mode for developing highly selective probes.

Synthesis and reactivity of metal carbene complexes with heterobiaryl spacer substituents

Mono- and binuclear Fischer carbene complexes, [M(CO)5{C(OR)Ar- ArX}], X = H, {C(OR)M?(CO)5}; M, M? = W or Cr; R = Me, Et or (CH2)4OMe; Ar = thiophene, N-methylpyrrole or furan units 1-20, were synthesized. For this purpose, mono-, bi- or stepwise lithiated bithiophene, N,N?-dimethylbipyrrole, thienylfuran and N-methyl(thienyl)pyrrole were reacted with chromium and tungsten hexacarbonyl precursors. Dilithiation in the 2- and 9-positions of N-methyl(thienyl)pyrrole could not be achieved. Alkylation of acyl metallates with triethyloxonium tetrafluoroborate or methyl trifluoromethanesulfonate in THF afforded not only the expected carbene complexes with ethoxy or methoxy substituents, but in the case of bithiophene with methyl trifluoromethanesulfonate, carbene complexes with alkoxy substituents incorporating a ring-opened tetrahydrofuran moiety. X-Ray crystallographic structure determinations were performed on [W(CO) 5{C(OMe)(thienylfuran)}] (14), [W(CO)5{C(OMe)(N- methylthienylpyrrole)}] (20) and [{W(CO)5}2{mu-C(OEt)(N, N?-dimethylbipyrrolylC(OEt)}] (12) to assess the role of the heterobiaryl substituent on the structural features of the carbene ligand in the complexes. Complexes [{Cr(CO)5}2{mu-C(OMe)bithienylC(OEt)}] (3), [(CO)5Cr{mu-C(OMe)bithienylC(OMe)}W(CO)5] (5) and [{Cr(CO)5}2{mu-C(OMe)thienylfuranC(OMe)}] (15) were reacted with 3-hexyne to study their behaviour in benzannulation reactions. The major products generated by the biscarbene complexes were regio-selectively determined by the nature of the metal site and that of the heteroatom in the arene rings. The monocarbene complexes [Cr(CO)5{C(OMe)thienylfuran] (13) and [Cr(CO)5{C(OEt)(N-methylthienylpyrrole)}] (19) were refluxed in THF for 2 hours in the presence of [Pd(PPh4)4] to afforded the carbene-carbene coupled olefinic products and small amounts of the corresponding 2-ethyl(biheteroaryl)acetate. By contrast, the biscarbene complex of thienylfuran (15), afforded only the 2,9-diester of thienylfuran. The Royal Society of Chemistry 2009.

The cytotoxicity and mechanism of action of new multinuclear Scaffold AuIII, PdII pincer complexes containing a bis(diphenylphosphino) ferrocene/non-ferrocene ligand

New multinuclear gold(iii), palladium(ii) pincer complexes containing bis(diphenylphosphino) ferrocene/non-ferrocene ligands of formula [(L)Au(mu2-eta2-CS3)Pd(dppf)](PF6)2, 1, and [(L)Au(mu2-eta2-CS3)Pd(dppe)](PF6)2, 2 (HL = 5-methoxy-1,3-bis (1-methyl-1H-benzo[d]imidazol-2-yl)benzene, dppf = 1,1?-bis(diphenylphosphino)ferrocene, and dppe = bis(diphenylphosphino)ethane) have been synthesized and fully characterized. Both complexes are more cytotoxic to a number of human cancer cell lines than cisplatin. Moreover, complex 1 is more active than auranofin as the reference gold compound against a panel of several human tumor cell lines. Chemosensitivity tests completed on cisplatin sensitive and resistant cell lines have confirmed that both complexes were able to overcome cisplatin resistance. The complexes successfully inhibited the enzymes thioredoxin reductase (TrxR) and glutathione reductase (GR). The cellular uptake of both gold and palladium of the complexes was studied, which indicated a high biological stability of the complexes. The complexes 1 and 2 increase the production of ROS in HCT-15 cells. In addition, these complexes induce major levels of cancer cell death by apoptosis.

A Dipolar Anthracene Dye: Synthesis, Optical Properties and Two-photon Tissue Imaging

Two-photon microscopy is a powerful tool for studying biological systems. In search of novel two-photon absorbing dyes for bioimaging, we synthesized a new anthracene-based dipolar dye (anthradan) and evaluated its two-photon absorbing and imaging properties. The new anthradan, 9,10-bis(o-dimethoxy-phenyl)-anthradan, absorbs and emits at longer wavelengths than acedan, a well-known two-photon absorbing dye. It is also stable under two-photon excitation conditions and biocompatible, and thus used for two-photon imaging of mouse organ tissues to show bright, near-red fluorescence along with negligible autofluorescence. Such an anthradan thus holds promise as a new class of two-photon absorbing dyes for the development of fluorescent probes and tags for biological systems.

Synthesis and spectroscopic properties of beta,beta?-dibenzo-3,5,8-triaryl-BODIPYs

A series of beta,beta?-bicyclo-3,5-diaryl-BODIPYs were synthesized from the corresponding beta,beta?-bicyclo-3,5-diiodo-BODIPYs (1a,b) via Pd(0)-mediated Suzuki cross-coupling reactions in 82-92% yields. Subsequent aromatization with DDQ afforded the corresponding beta,beta?-dibenzo-aryl-BODIPYs, which showed red-shifted absorptions and emissions in the near-IR range. The dibenzo-appended BODIPYs showed characteristic 1H-, 13C-, 11B- and 19F-NMR shifts, and nearly planar conformations by X-ray crystallography.

Ultrashort helix pitch antiferroelectric liquid crystals based on chiral esters of terphenyldicarboxylic acid

Antiferroelectric liquid crystals (AFLCs) with a nanoscale helix pitch (<100 nm) were revealed in a composition containing achiral smectic-C biphenylpyrimidines and two non-mesogenic chiral dopants: p-terphenyldicarboxylates of chiral (2S)-1,1,1-trifluorooctane-2-ol and (S,S)-1,1,1-trifluorooctan-2-yl 2-hydroxypropanoate. The prepared multicomponent AFLCs exhibit two electro-optical effects, which are interrelated with the chemical structures of the mixture's components. The first effect is hysteresis free under special voltage waveform U-shaped switching, which exhibits an electro-optical response similar to that of nematic liquid crystals (NLCs) but around 1-2 orders of magnitude faster. Secondly, the deformed helix antiferroelectric liquid crystal (DHAFLC) effect has been investigated. The observed temperature independence of the electro-optical parameters, in a certain temperature range, combined with a fast U-shape response or with DHAFLC, adds a great value for applications. We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 95464-05-4, and how the biochemistry of the body works.Related Products of 95464-05-4

Total synthesis of ent-dioxepandehydrothyrsiferol via a bromonium-initiated epoxide-opening cascade

(Chemical Equation Presented) In the first total synthesis of ent-dioxepandehydrothyrsiferol, the signature trans-anti-trans 7,7,6-fused tricyclic polyether framework was constructed in a single bromonium-initiated epoxide-opening cascade that incorporates both endo- and exo-selective epoxide openings, each directed by the substitution pattern of the epoxide (methyl groups). This study thus demonstrates the feasibility of a possible biogenesis.

Regioselective hydroesterification of 1-alkynes catalyzed by palladium- phosphine complexes

The reaction of 1-alkynes, CO, and methanol (hydroesterification) catalyzed by palladium-phosphine complexes has been studied in acetonitrile media. Branched alpha,beta-unsaturated ester was mainly produced in the presence of a catalytic amount of a palladium complex containing PPh3. In contrast, dppf-based palladium complexes showed excellent regioselectivity for the formation of linear alpha,beta-unsaturated ester. On the other hand, hydroesterification of 1,7-octadiyne with a catalyst system of Pd(OAc)2/PPh3/TsOH followed a different path to give a cyclized carbonylation product aS the major product. A tentative mechanism involving a PdH species has been proposed for these reactions. (C) 2000 Elsevier Science B.V.
