Ligand-controlled Assembly of Cd(II) Metal-Organic Coordination Polymers Based on 3,5-Dinitrobenzoate and Flexible Bis(imidazole) Derivatives

Three new Cd(II) metal-organic coordination polymers, [Cd(bbi)(DNBA)(2)] (1), [Cd(bbbi)(DNBA)(2)] (2), and [Cd(dmbbbi)(DNBA)Cl]center dot 0.38H(2)O (3) [HDNBA = 3,5-dinitrobenzoic acid, bbi = 1-(1,4-butanediyl)bis(imidazole), bbbi = 1,1-(1,4-butanediyl)bis(benzimidazole), and dmbbbi = 1,1-(1,4-butanediyl)bis(5,6-dimethylbenzimidazole)], have been obtained from hydrothermal reactions of cadmium(II) chloride with the mixed ligands HDNBA and the three structurally related flexible bis(imidazole) derivatives. Single-crystal X-ray diffraction analyses have revealed that the dinuclear cadmium clusters acting as nodes interlinked by two mu(2)-carboxylic groups, are connected to four other clusters through bridging bbi (for 1) and bbbi (for 2) units to generate two extended two-dimensional (2-D) networks. Compound 3 features a 1-D zigzag chain structure. A systematic structural comparison of the title compounds indicates that the conformations and the steric hindrance of flexible bis(imidazole) derivatives each play an important role in the formation of the Cd(II) coordination polymers. The thermal stability of 1 and 2, and the luminescence behavior of 3 were also investigated.

EFFECTS OF IMIDAZOLE DERIVATIVES ON CYTOCHROMES-P450 FROM HUMAN HEPATOCYTES IN PRIMARY CULTURE

The expression of several forms of cytochrome P450 including P450 1A2, 2D6, 2E1 and 3A was investigated in human hepatocytes maintained in primary culture for 96 h in the absence or presence of 50-mu-M of various imidazole derivatives. These included ketoconazole, clotrimazole, miconazole, fluconazole, secnidazole and metronidazole. In addition, the typical inducers rifampicin and beta-naphthoflavone were used for comparison. Western and Northern blot analysis of microsomes and RNA prepared from these cultures as well as de novo synthesis experiments revealed that, among the imidazole derivatives tested, only clotrimazole was a strong rifampicin-like inducer of P450 3A. The expression of the other forms of P450 tested was not affected by the treatments. Analysis of the inhibition of 13 monoxygenase activities, including ethoxyresorufin and phenacetin O-deethylases, coumarin 7-alpha-, lauric acid 11- and 12-, mephenytoin 4-, debrisoquin 4-, and aniline hydroxylases, benzphetamine, aminopyrine, mephenytoin and erythromycin demethylases, and cyclosporin oxidase (representative of 10 different forms of P450 in human liver microsomes) revealed that ketoconazole was a strong and selective in vitro inhibitor of P450 3A (cyclosporin oxidase) with a K(i) < 1-mu-M. Clotrimazole and miconazole were also strong inhibitors of P450 3A-mediated activities in contrast to the other imidazole derivatives.

Solid state hydrogen bonding in imidazole derivatives: a persistent tape motif

The Cambridge Structural Database was mined for non N-substituted, neutral imidazole derivatives. Solid states with metal centres bound to the imidazole nitrogen atoms and ionic species were not included. The N-N, hydrogen-bound, tape motif was found to be a structural trend in the solid-state of neutral imidazole derivatives in the presence of possible competing hydrogen bonds and in highly steric environments. A chemically intuitive set of parameters was chosen to characterize the relationships between imidazole rings in the solid states. The choice of structural parameters and the values these parameters take as a function of substitution patterns of imidazole derivatives was discussed. The complexities that can arise in the crude extraction of hydrogen bond strength from solid state data was discussed.

Utilization of cyanothioformamides in the syntheses of various types of imidazole derivatives

When, cyanothioformamide derivatives are reacted with certain electrophiles, they produce imidazole, oxazole, thiazole, 2,5-thiadiazole, bis-imidazole and bis-oxazole derivatives; while the reaction with certain nucleophiles furnish benzoxazole, quinaolinone, triazole, bis-triazole, benzoxazinethione and 1,3,4-thiadiazole derivatives. Imidazolidineiminothione derivatives were obtained by ring closure reaction of cyanothioformamide derivatives with isocyanates. These reactions give rise to imidazole derivatives that contain adjacent thione and imino functional groups in the positions 4 and 5 which are reactive in numbers of subsequent ring closure reactions. These compounds find applications as medicinal and pharmacological agents.

Continuous-flow photo-induced decarboxylative annulative access to fused imidazole derivatives via a microreactor containing immobilized ruthenium

Visible-light-driven continuous-flow decarboxylative annulation was achieved and used along with a microreactor containing immobilized ruthenium catalyst to construct valuable fused imidazole derivatives with high yields under an open atmosphere. Notably, this chemistry included the use of l-proline and alpha-azidochalcone as precursors of an alpha-amino radical and 2H-azirine via photo-induced decarboxylation and denitrogenation, respectively, to give the annulated imidazole derivatives as a result of the formation of two new C-N bonds. Moreover the novel, environmentally benign and efficient continuous-flow protocol was further improved by carrying out the reaction in a polydimethylsiloxane (PDMS) microreactor with immobilized Ru3+ under fluorescent or white LED light, enabling excellent yields (70-94%) at a reaction time (2 min) significantly shorter than that (16 h) of the batch protocol.

Studies on interaction between an imidazole derivative and bovine serum by spectral methods

The interaction between a trifluoromethyl substituted imidazole derivative 2-(4-(trifluorometh yl)phenyl)-1-phenyl-1H-imidazo[4,5-f] [1,10] phenanthroline (tfmppip) and bovine serum albumin (BSA) was investigated by solution spectral studies. The observed experimental result shows that the imidazole derivative has strong ability to quench the fluorescence of BSA by forming complex which is stabilized by electrostatic interactions. The effective quenching constants (k(sv)) were 2.79 x 10(4), 2.51 x 10(4), and 2.32 x 10(4) at 301, 310 and 318 K respectively. The Stern-Volmer quenching constant (K-sv), binding site number (n), apparent binding constant (K-A) and corresponding thermodynamic parameters (Delta G, Delta H and Delta S) were calculated. The distance between the donor (BSA) and acceptor (tfmppip) was obtained according to fluorescence resonance energy transfer (FRET). Conformational changes of BSA were observed from synchronous fluorescence technique. The effect of metal ions such as Cu2+, Zn2+, Ca2+, Mg2+, Ni2+, Co2+ and Fe2+ on the binding constants between the imidazole derivative and BSA were also studied. (C) 2012 Elsevier B.V.
