N-oxides of adenosine-type nucleosides undergo pyrimidine ring opening and closure to give 5-amino-4-(1,2,4-oxadiazol-3-yl)imidazole derivatives

Treatment of acylated adenosine N-oxides with carboxylic anhydrides and thiophenol resulted in pyrimidine ring opening followed by exocyclic ring closure. Ammonolysis gave 5-amino-4-(5-substituted-1,2,4-oxadiazol-3-yl)-1-(beta-D-ribofuranosyl) imidazole derivatives, whereas iodine in methanol selectively unmasked the 5-amino group. Related flexible nucleoside analogues can be prepared from adenine-type precursors.

Synthesis and antibacterial activity of novel and potent DNA gyrase inhibitors with azole ring

The 4-piperidyl moiety and the pyrazole ring in 1-(3-chlorophenyl)-5-(4-phenoxyphenyl)-3-(4-piperidyl)pyrazole 2, which has previously shown improved DNA gyrase inhibition and target-related antibacterial activity, were transformed to other groups and the in vitro antibacterial activity of the synthesized compounds was evaluated. The selected pyrazole, oxazole and imidazole derivatives showed moderate inhibition against DNA gyrase and topoisomerase IV with similar IC50 values (IC50 = 9.4-25 mug/mL). In addition, many of the pyrazole, oxazole and imidazole derivatives synthesized in this study exhibited potent antibacterial activity against quinolone-resistant clinical isolates and coumarin-resistant laboratory isolates of Gram-positive bacteria with minimal inhibitory concentration values equivalent to those against susceptible strains.

Effect of 1-substituted imidazole derivatives for the curing process of epoxy-isocyanate composition

The kinetics of the curing process of isocyanate-epoxy materials hardened in the presence of 1-substituted imidazole derivatives was studied by the Coast-Redfern method. The extent of a conversion parameter of the curing process in two ways was calculated: DSC (peak area integration) and rheology (viscosity changes). The activation energy values were determined for epoxy-isocyanate cured in the presence of 0.5; 1.0 and 2.0 phr 1-substituted imidazole derivatives respectively. Increasing of accelerators amount results in decreasing the activation energy and other kinetic parameters.

SYNTHESIS AND OPTICAL PROPERTIES OF 2,2 ‘-BIIMIDAZOLE AND BENZO[d]IMIDAZOLE DERIVATIVES: CHANGING pi-CONJUGATION BY PHOTOEXCITATION

1,1′,5,5′-Tetraaryl-2,2′-biimidazole and benzo [d] imidazole derivatives were synthesized. Symmetrical and unsymmetrical benzo[d]imidazole derivatives could be obtained by the Pd-catalyzed coupling reaction between 2-iodo-benzo[d]imidazole and the corresponding (benzo)imidazole anion. Hypsochromic shifts in absorption and fluorescence spectra of 1,1′,5,5′-tetraaryl-2,2’-biazole were observed by switching pyrrole rings for imidazole and benzo[d]imidazole rings, resulting in compounds with various Stokes shifts. Based on the (TD)DFT calculation, it was reasoned that changing the conformation of each single bond from a twisted to planar structure by photoexcitation led to larger Stokes shifts.

Conformation study on recognition of imidazole derivatives by chiral amino acids linked porphyrins

Chiral recognition is an attractive subject in the area of host-guest chemistry. Conformation study is performed to understand chiral recognition of zinc(II) porphyrin with imidazole derivatives on a molecular level. The molecular recognition of three novel chiral zinc porphyrin(1-3) with four types of imidazole derivatives was studied. The conformation searching of this host-guest system was studied by using simulated annealing method on the basis of Tripos force field. The different minimal energy conformation of imidazole combind with porphyrin was studied. The quantum chemistry calculation was performed to calculate the single-point energies of the host-guest system. The minimal energy conformation of ZnT(o-BocAla)APP (3)-Im showed that Im attaching from the singleside chain of the host had the reasonable configuration than that from the three-side chain. The former also had the lower energy than the latter. And the quantum chemistry calculation results of orbital energy, DeltaE(L-H), and atomic net charge revealed the same way. The results illumate that combination oriention of the host-guest system is the single chain of the hosts.

SYNTHESIS AND BIOLOGICAL EVALUATION OF NOVEL IMIDAZOLE DERIVATIVES AS POTENT ANTICONVULSANT AGENTS

In this study, we have made an attempt to synthesize novel imidazole derivatives (2a-h) and evaluate them for anticonvulsant activity using maximal electroshock method (MES). In the first step, substituted amines were allowed to react with substituted benzaldehyde in an equimolar amount with glacial acetic acid to form various substituted Schiff’s base intermediate (1a-h). Schiff’s base on treatment with benzil in the presence of ammonium acetate afforded corresponding imidazole derivatives (2a-h). The structure of the final analogs has been confirmed on the basis of elemental analysis, Fourier transform infrared spectroscopy (FT-IR), H-1 nuclear magnetic resonance (NMR), C-13 NMR, and mass spectra. Among all synthesized compounds, compounds 2a, 2f, and 2b were found to be most potent in comparison with standard phenytoin. [GRAPHICS]
