High-dimensional assembly depending on polyoxoanion templates, metal ion coordination geometries, and a flexible bis(imidazole) ligand

By introducing the flexible 1,1'-(1,4-butanediyl)bis(imidazole) (bbi) ligand into the polyoxovanadate system, five novel polyoxoanion-templated architectures based on [As8V14O42](4-) and [V16O38Cl](6-) building blocks were obtained: [M(bbi)(2)](2)[As8V14O42(H2O)] [M = Co (1), Ni (2), and Zn (3)], [Cu(bbi)](4)[As8V14O42(H2O)] (4), and [Cu(bbi)](6)[V16O38Cl] (5). Compounds 1-3 are isostructural, and they exhibit a binodal (4,6)-connected 2D structure with Schlafli symbol (3(4)center dot 4(2))(3(4)center dot 4(4)center dot 5(4)center dot 6(3))(2), in which the polyoxoanion induces a closed four-membered circuit of M-4(bbi)(4). Compound 4 exhibits an interesting 3D framework constructed from tetradentate [As8V14O42](4-) cluster anions and cationic ladderlike double chains. There exists a bigger M-8(bbi)(6)O-2 circuit in 4. The 3D extended structure of 5 is composed of heptadentate [V16O38Cl](6-) anions and flexural cationic chains; the latter consists of six Cu(bbi) segments arranged alternately. It presents the largest 24-membered circuit of M-24(bbi)(24) so far observed made of bbi molecules and transition-metal cations. Investigation of their structural relations shows the important template role of the polyoxoanions and the synergetic interactions among the polyoxoanions, transition-metal ions, and flexible ligand in the assembly process.

Syntheses, crystal structures and properties of two Cu(II) coordination polymers: Cu(C3N2H4)(2)(HL)(2) andCU(C3N2H4)(2)L with C3N2H4 = imidazole, H2L = adipic acid

The reactions of freshly prepared Cu(OH)(2).xH(2)O and Cu(OH)(2-2y)(CO3)(y).zH(2)O precipitates with imidazole and adipic acid in CH3OH/H2O at pH = 5.4 yielded CU(C3N2H4)(2)(HL)(2) 1 and CU(C3N2H4)(2)L 2, respectively. Complex 1 consists of ribbon-like polymeric chains (1)(infinity)[CU(C3N2H4)(2)(HL)(4/2)], in which the octahedrally coordinated Cu atoms are doubly bridged by bis-monodentate hydrogen adipato ligands. The interchain N-H...O hydrogen bonding interactions are responsible for supramolecular assembly of the polymeric chains into open 3D frameworks and two-fold interpenetration of the resulting open frameworks completes the crystal structure of 1. Within complex 2, the Cu atoms are penta-coordinated to form CuN2O3 square pyramids and condensed into CU2N4O4 dimers, which are doubly bridged by twisted bis-monodentate adipato ligands into polymeric chains (1)(infinity)([CU(C3N2H4)(2)](2)L-4/2) with 4- and 18-membered rings progressing alternatively. The polymeric chains are assembled due to interchain N-H...O hydrogen bonding interactions. The thermal and magnetic behaviors of 1 and 2 is discussed.

Novel < 110 >-oriented organic-inorganic perovskite compound stabilized by N-(3-aminopropyl) imidazole with improved optical properties

In the organic-inorganic perovskites family, the < 100 >-oriented type has been extensively investigated as a result of its unique magnetic, optical, and electrical properties, and only one type of < 110 >-oriented hybrid perovskite stabilized by methylammonium and iodoformamidinium cations or the latter themselves has been known so far. In this paper, another novel < 110 >-oriented organic-inorganic perovskite (C6H13N3)-PbBr4 (compound 1) has been prepared by reacting N-(3-aminopropyl)imidazole (API) with PbBr2 in hydrobromic acid. The crystal structure is determined, which indicates that the perovskite is stabilized by API. The introduction of the optically active organic ligand API into the hybrid perovskite results in a red shift and a great enhancement of photoluminescence in the perovskite with respect to organic ligand API itself. These results have been explained according to calculation based on density-functional theory. Moreover, the excellent film processing ability for the perovskite (C6H13N3)PbBr4 together with the improved optical properties makes it have potential application in optoelectronic devices.

Tuning of emission: Synthesis, structure and photophysical properties of imidazole, oxazole and thiazole-based iridium (III) complexes

Three new iridium (III) complexes with two cyclometalated (CN)-N-boolean AND ligands (imidazole, oxazole and thiazole-based, respectively) and one acetylacetone (acac) ancillary ligand have been synthesized and fully characterized. The structure of the thiazole-based complex has been determined by single crystal X-ray diffraction analysis. The Ir center was located in a distorted octahedral environment by three chelating ligands with the N-N in the trans and C-C in the cis configuration. By changing the hetero-atom of (CN)-N-boolean AND ligands the order S, O and N, a marked and systematic hypsochromic shift of the maximum emission peak of the complexes was realized. The imidazole-based complex emits at a wavelength of 500 nm, which is in the blue to green region. The tuning of emission wavelengths is consistent with the variation of the energy gap estimated front electrochemistry results. An electroluminescent device using the thiazole-based complex as a dopant in the emitting layer has been fabricated. A highly efficient yellow emission with a maximum luminous efficiency of 9.8 cd/A at a current density of 24.2 mA/cm(2) and a maximum brightness of 7985 cd/m(2) at 19.6 V has been achieved.

Synthesis and structural characterization of a new molecule-based complex constructed from dodecamolybdophosphoric acid and imidazole

A new compound, (CH5N2)(3)(PMo12O40CH4N23H2O)-C-.-H-. (1), was synthesized and structurally characterized by elemental analyses, IR spectra, UV spectra, NMR spectra and ESR spectra. This is, to our knowledge, the first example of an imidazole-polyoxometalate species. The compound was recrystallized from N,N-dimethylformamide (DMF), and then black block-like crystals of (C3H5N2)(4)((PMoMo11O40)-Mo-V-O-VI)(.)4C(3)H(7)NO(.) 2H(2)O (2), were obtained. It crystallizes in a triclinic space group P (1) over bar with n=12.423(3) Angstrom, b=12.666(3) Angstrom, c=13.341(3) Angstrom, alpha=70.56(3)degrees, beta=71.16(3)degrees, gamma=64.18(3)degrees, V= 1742.3(6) Angstrom(3), Z=1, R1 = 0.0585, wR2 = 0.1885. An X-ray crystallographic study showed that the crystal structure is constructed by electrostatic attractions and hydrogen bonds between a dodecamolybdophosphoric anion and an imidazole. The imidazole and DMF molecules occupy cavities in a polyoxometalate lattice ordered along a c-axis. The structure of (2) is similar to that of (1) from a comparison of both IR spectra and TGA Curves.

Networks with hexagonal circuits in co-ordination polymers of metal ions (Zn-II, Cd-II) with 1,1 '-(1,4-butanediyl)bis(imidazole)

Three new compounds, [ZnL1.5(H2O)(SO4)]. 6H(2)O 1, [ZnL1.5(H2O)(2)][NO3](2). 2H(2)O 2 and [CdL1.5(H2O)(2)(SO4)]. 4H(2)O 3 were obtained from self-assembly of the corresponding metal salts with 1,1'-(1,4-butanediyl)bis(imidazole) (L). In both 1 and 2 zinc ion is five-co-ordinated, showing a less-common trigonal bipyramidal co-ordination polyhedron, while cadmium ion of 3 is six-co-ordinated with a common octahedral arrangement. The sulfate ions of 1 and 3 are co-ordinated, however the nitrate ions of 2 are not. Each of the three compounds is composed of a (6, 3) network with the hexagonal smallest circuit containing six metal ions and six L; each L is co-ordinated to two metal ions, acting as a bridging ligand. In 1 the 2-D sheet of (6, 3) networks is interpenetrated in an inclined mode by symmetry related, identical sheets to give an interlocked 3-D structure, while the (6, 3) networks of both 2 and 3 stack in a parallel fashion to construct frameworks having channels.

Investigation of metalloporphyrins and their imidazole complexes using electrospray ionization mass spectrometry

Three compounds of metalloporphyrins were studied using electrospray ionization mass spectrometry. The bonding power between substitutional phenyl and porphyrin cycle and the coordinate conditions of metalloporphyrins with imidazole were discussed. The experimental result indicated that the bonding power between substitutional phenyl and porphyrin cycle in metalloporphyrins became weak from Mn, Fe to Co. The complexes abundances formed by metallophorphyrin with imidazole were stronger with the increase of the ligand concentration. At the same ligand concentration, the abundance of the complexes was intensified gradually and the stability of the ligands was become stronger from Mn, Fe to Co.

A new two-dimensional hybrid zinc phosphate with electro-neutral open-framework has been hydrothermally synthesized by using imidazole as a structure-directing agent, whose structure is characterized with 3-, 4-, 5, and 12-ring layers and coordination bonds between imidazole groups and zinc atoms, resulting in primary building units of ZnO2N2 and ZnO3N.

Diisothiocyanatobis(1-vinyl-1H-imidazole-kappa N-3)-copper(II)

In the title compound, [Cu(NCS)(2)(C5H6N2)(2)], each Cu atom is coordinated by two N atoms from two Eim (Eim = 1-vinyl-1H-imidazole) ligands and two N atoms from two isothiocyanate groups. The Cu atom adopts a square-planar geometry. The mean Cu-N(Eim) and Cu-N(NCS) distances are 1.960 (6) and 1.993 (6) angstrom, respectively.

2-(2-Phenyl-1H-phenanthro-[9,10-d]imidazole-1-yl)-acetic acid (PPIA) and its application for determination of amines by high performance liquid chromatography with fluorescence detection and identification with mass spectroscopy/atmospheric pressure chemical ionization

A simple, sensitive, and mild method for the determination of amino compounds based on a condensation reaction with 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide hydrochloride (EDC-HCI) as the dehydrant with fluorescence detection has been developed. Amines were derivatized to their acidamides with labeling reagent 2-(2-phenyl-1H-phenanthro-[9,10-d]imidazole-1-yl)-acetic acid (PPIA). Studies on derivatization conditions indicated that the coupling reaction proceeded rapidly and smoothly in the presence of a base catalyst in acetonitrile to give the corresponding sensitively fluorescent derivatives with an excitation maximum at lambda(ex) 260nm and an emission maximum at lambda(em) 380nm. The labeled derivatives exhibited high stability and were enough to be efficiently analyzed by high-performance liquid chromatography. Identification of derivatives was carried out by online post-column mass spectrometry (LC/APCI-MS/MS) and showed an intense protonated molecular ion corresponding m/z [MH](+) under APCI in positive-ion mode. At the same time, the fluorescence properties of derivatives in various solvents or at different temperature were investigated. The method, in conjunction with a gradient elution, offered a baseline resolution of the common amine derivatives on a reversed-phase Eclipse XDB-C-8 column. LC separation for the derivatized amines showed good reproducibility with acetonitrile-water as mobile phase. Detection limits calculated from 0.78 pmol injection, at a signal-to-noise ratio of 3, were 3.1-18.2 fmol. The mean intra- and inter-assay precision for all amine levels were < 3.85% and 2.11%, respectively. Excellent linear responses were observed with coefficients of > 0.9996. The established method for the determination of aliphatic amines from real wastewater and biological samples was satisfactory. (c) 2006 Elsevier B.V. All rights reserved.

QM/MM and Classical Molecular Dynamics Simulation of Histidine-Tagged Peptide Immobilization on Nickel Surface

The hybrid quantum mechanics (QM) and molecular mechanics (MM) method is employed to simulate the His-tagged peptide adsorption to ionized region of nickel surface. Based on the previous experiments, the peptide interaction with one Ni ion is considered. In the QM/MM calculation, the imidazoles on the side chain of the peptide and the metal ion with several neighboring water molecules are treated as QM part calculated by “GAMESS”, and the rest atoms are treated as MM part calculated by “TINKER”. The integrated molecular orbital/molecular mechanics (IMOMM) method is used to deal with theQMpart with the transitional metal. By using the QM/MM method, we optimize the structure of the synthetic peptide chelating with a Ni ion. Different chelate structures are considered. The geometry parameters of the QM subsystem we obtained by QM/MM calculation are consistent with the available experimental results. We also perform a classical molecular dynamics (MD) simulation with the experimental parameters for the synthetic peptide adsorption on a neutral Ni(1 0 0) surface. We find that half of the His-tags are almost parallel with the substrate, which enhance the binding strength. Peeling of the peptide from the Ni substrate is simulated in the aqueous solvent and in vacuum, respectively. The critical peeling forces in the two environments are obtained. The results show that the imidazole rings are attached to the substrate more tightly than other bases in this peptide.

新型非肽类血管紧张素II受体拮抗剂设计合成及其生物活性研究

Ang II受体拮抗剂是作用于肾素-血管紧张素系统(RAS)的抗高血压药，因其抗高血压作用与较老的抗高血压药物作用相同，且更具有选择性，不良反应状况与安慰剂相似,而在高血压治疗中逐渐引起研究者重视，并成为目前增长最快的抗高血压药物。在许多AngII受体拮抗剂中四氮唑结构已成为固定基团，但四氮唑有许多合成及代谢弊端。因此，寻找其他合适的杂环酸性基团来替代四氮唑，在保持较高口服活性的同时克服相应缺陷，具有极其重要的意义。 本项目以四氮唑沙坦类药物为先导化合物，运用生物电子等排原理及拼合原理，根据计算机分子模拟研究结果，对其进行结构修饰和改造，首次将咪唑、氯代咪唑、三氮唑及咪唑啉替代四氮唑，并结合具有较高AngII受体拮抗活性的联苯并咪唑衍生物，设计并合成一系列含咪唑，咪唑啉，氯代咪唑及三氮唑衍生物的Ang II受体拮抗剂。 研究这一系列新型AngII受体拮抗剂的体内、体外抗高血压活性时，发现咪唑啉衍生物展示了与对照药物几乎相当的活性，而咪唑、氯代咪唑和三氮唑衍生物分别表现了较弱或者没有活性，这些研究对今后更进一步设计合成新的Ang II受体拮抗剂具有重要的指导意义，同时也为筛选抗高血压药物奠定良好的基础。 The angiotensin II receptor antagonists act on renin-angiotensin system (RAS), which are as effective as other types of anti-hypertensive drugs. Because even the more specific and comparable to placebo in terms of side effects, Ang II receptor antagonists cause a high attention and become the fastest growing anti-hypertension drugs. Most of such compounds share the biphenyltetrazole unit with the lead Losartan. However, there are many defects in tetrazole synthesis and vivo metabolism. Therefore, we felt quite encouraged to find some proper acidic heterocyclic groups which maintain the same oral bioavailability to replace the tetrazole. In the present paper, we applied the bioisostere and combination principle, in accordance with the results of computer modeling of molecular, to modify the lead structural of terazole in sartan compounds reported. We turned our attention to replace the tetrazole ring with imidazole rings, chloro-imidazole, imidazoline, traizole ring and combinated them with benzimidazoles derivatives which have antagonistic activity for angiotensin II to design and synthesize a series of Ang II receptor antagonists contaning imidazole ring, chloro-imidazole, imidazoline or traizole ring. In addition, activity tests in vivo and in vivo had shown that imidazoline derivatives display almost equivalent activity with the reference drug, but imidazole derivatives, chloro-imidazole, triazole derivatives were weak or non-performance of the hypotensive activity. We believe that the imidazoline derivative type Ang II receptor antagonists can build a foundation for the development of a novel series of anti-hypertensive drugs.

人载脂蛋白APOA5的克隆表达纯化及相互作用蛋白研究

人类的载脂蛋白A5（apolipoprotein A5，APOA5）是一个新近发现的载脂蛋白家族成员。它在血浆中的含量比其他载脂蛋白低1-2个数量级，但能显著影响血浆三酰甘油水平，对血脂代谢具有重要意义，可以作为降血脂药物治疗中一个强有力的潜在靶标。 由于APOA5在血浆中含量低，直接从血浆中分离纯化很困难，国内一直没有报道简易可靠的纯化方法。为进一步研究APOA5的生物学特性，探讨其与TG代谢中的其它关键成分之间的相互关系，揭示其在脂类代谢相关疾病中的重要地位，必须有大量的蛋白和抗体用于基础研究。因此本研究首先利用基因工程技术，诱导表达纯化APOA5蛋白，免疫动物制备多克隆抗体，为进一步研究人肝脏细胞中APOA5的相互作用蛋白，研究APOA5蛋白在肝脏细胞中的功能奠定基础。 为了深入研究APOA5在肝脏中如何行使功能，我们采用细菌双杂交技术寻找与APOA5相互作用的蛋白因子。并采用Pull-down技术，免疫荧光及免疫共沉淀技术进一步确证其在体外和体内的相互作用关系，为进一步阐明APOA5在体内的生理功能提供了新的线索。 第一部分 APOA5基因的克隆、原核表达、纯化及其多克隆抗体的制备 本研究首先应用基因克隆技术，从人肝癌细胞系SMMC-7721的cDNA中扩增出1.1 kb的ApoA5基因全长序列。然后将其克隆至表达载体pThioHisD，构建原核表达载体pTH-APOA5。该重组质粒转化至大肠杆菌 BL21（DE3），成功实现人APOA5融合蛋白在大肠杆菌中的表达。经发酵得到高效表达的融合蛋白。 融合蛋白在 IPGT 诱导下以包涵体的形式大量表达。利用融合蛋白上的一段组氨酸序列，用镍离子亲和柱进行纯化和复性后，获得较高纯度的人APOA5融合蛋白。利用该融合蛋白免疫新西兰大耳白兔，获得了高效价的兔抗人APOA5多克隆抗体，Western Blot结果显示此多克隆抗体与APOA5特异性结合。 第二部分 细菌双杂交筛选与APOA5相互作用的蛋白 本实验首先构建了pBT-APOA5重组质粒，经双酶切、PCR和测序鉴定证明重组诱饵质粒构建成功，并进行了表达、自激活鉴定。Western Blot鉴定证实报告菌株中表达了分子量为 68 kD左右的重组融合蛋白，与预测的分子量APOA5（41 kD）/lamda cI （27 kD）一致。自激活实验证明诱饵蛋白不能单独激活报告基因，可用于筛选人肝脏cDNA文库。经过双重抗性筛选和回复筛选，分离出10个阳性克隆。对结果进行生物信息学分析，得到7个与APOA5相互作用的蛋白，其中BI1为细胞凋亡调节因子；ATP6、CYTB、ND2、COX-1为线粒体表达蛋白； ALB、TTR为血清蛋白。 第三部分 APOA5与BI1相互作用的确证 首先构建了BI1的原核表达载体pGEX-5X-3-BI1，利用Pull-down实验检测了APOA5与BI1在体外具有相互作用。然后构建了BI1的真核表达载体pCDNA3.1-HA-BI1和APOA5的真核表达载体pCDNA3.1-APOA5，并验证其表达。通过免疫荧光细胞内共定位研究发现，靶蛋白APOA5主要分布于胞浆，与BI1在HEK293细胞有共定位，即APOA5与BI1存在相互作用的可能。最后利用免疫共沉淀手段，在HEK293细胞中确证了靶蛋白APOA5与BI1在体内的相互作用。 上述研究结果，为深入研究APOA5在体内的生物学功能提供了新的思路。 Apolipoprotein A5 (APOA5) is a newly discovered protein belongs to apolipoprotein family. APOA5’s concentration is 1-2 orders of magnitude lower than other apolipoproteins in the circulation. APOA5 significantly affected plasma triglyceride levels, which is important on lipid metabolism. APOA5 has strong potential to be used as a hypolipidemic drug target. Large amount of APOA5 protein and antibodies are needed in basic research, such as biological characteristics study of the APOA5, its relationship with other key components in TG metabolism, its role played in Lipid metabolism-related diseases. Due to its low concentration in plasma, separation and purification of APOA5 from the plasma is very difficult. Until now no report on simple and reliable method for purification has been published in China. In this study, we firstly got APOA5 recombinant protein using genetic engineering technology. The purified recombinant protein was used to immunize rabbits to get antiserum. It is important for further study of the APOA5 protein-interacting protein. And it lays the foundation for studing APOA5 function in liver. In order to study APOA5 function in liver, we used bacterial two-hybrid technology to find the APOA5 protein interactor. Pull-down, immunofluorescence and immunoprecipitation techniques were used to further confirm the interaction between APOA5 with its interactor in vitro and in vivo. All of these stdudies provided new clues on its physiological functions in vivo. Part I: Cloning, prokaryotic expression, purification and polyclonal antibody preparation of APOA5 First of all, we amplified APOA5 CDS sequence from the human hepatoma cell line SMMC-7721, and subcloned into Expression vector pThioHisD, and got the recombinants named pTH-APOA5. The plasmid was transformed to BL21 (DE3). E. coli BL21(DE3) cells bearing the pTH-APOA5 plasmid were cultured and APOA5 protein synthesis was induced by the addition of IPTG. Recombinant protein was expression in the form of inclusion. Inclusion bodies were dissolved in phosphate-buffered saline containing 8 M urea and 40 mM imidazole, then applied to a Ni2+ affinity column, and were eluted in a buffer containing 4 M urea and 200 mM imidazole. Fractions containing the APOA5 protein were pooled and dialyzed against buffer containing phosphate-buffered saline. Antiserum to recombinant human APOA5 was generated by immuning rabbit. Western Blot showed that this antiserum specific binding with APOA5. Part II Two-hybrid system screening protein interactions with the APOA5 The coding sequence of human APOA5 was amplified using synthetic oligonucleotide primers from pTH-APOA5 vector and was subcloned into the pBT plasmidc to yield pBT-APOA5 vector. DNA sequencing was performed to verify that no unwanted mutations occurred during the process of plasmid vector construction. We verified recombinant protein expression and tested self-activation by pBT-APOA5 prior to screening. Western Blot verified inducing a 68 kD band, consistent with the predicted molecular weight (APOA5 41 kD, lamda cI 27 kD). pBT-APOA5 can be used for screening human liver cDNA library because it can not self-activation. Totally 10 positive clones were isolated. The nucleotide sequence of the positive clones were determined and compared to NCBI nucleotide sequence databases. We got 7 protein which interact with APOA5, included BI1(Apoptosis regulator); ATP6, CYTB, ND2, COX-1(Mitochondrial protein) and ALB, TTR(Serum protein). Part III Confirming of interaction between APOA5 with BI1 pGEX-5X-3-BI1 vector was subcloned at first. Pull-down experiments were used to detect the interaction between APOA5 with BI1 in vitro. Later, pCDNA3.1-HA-BI1 and pCDNA3.1-APOA5 were subcloned. Through immunofluorescence co-localization study, we found APOA5 mainly distributed in the cytoplasm. APOA5 is co-localization with BI1 in HEK293 cells. Finally, we verified interaction between APOA5 with BI1 in vivo through immunoprecipitation.
