Copper-Catalyzed Synthesis of Fused Imidazopyrazine N-Oxide Skeletons

N-Propargyl-2-aroylimidazoles synthesized and converted into the corresponding ketoximes. Under various conditions, several mono- and diketoxime imidazole derivatives were formed by converting the carbonyl or carbonyl and propargyl groups into oxime groups. N-Propargyl monooxime imidazole derivatives were cyclized by treatment with CuI to give various imidazopyrazine N-oxides. Several copper salts, such as CuOAc, CuSO (4) , and CuOTf, formed the same cyclization product. This cyclization reaction occurred only in the presence of Cu(I) or Cu(II) salts; other transition metals such as Au, Ag, In, and Fe did not yield cyclic products. The nucleus-independent chemical shift method was used to calculate the aromaticity of the bicyclic rings.

Anti-Candida Activity of 4-Morpholino-5-Nitro- and 4,5-Dinitro-Imidazole Derivatives

The activities of some 4-morpholino-5-nitro- and 4,5-dinitro-imidazole derivatives with respect to several Candida species were evaluated. It is established that 4,5-dinitroimidazole derivatives constitute an important group of compounds possessing antifungal activity against Candida species. Some analogs showed moderate antifungal ability in vitro, especially in relation well-known antifungals such as flucytosine (5FC). The best results of antifungal action were obtained for 1-(3-bromo-2-hydroxypropyl)-2-methyl-4,5-dinitroimidazole (3c), 1-(3-bromo-2-oxopropyl)-2-methyl-4,5-dinitroimidazole (4c) and 2-methyl-1-phenacyl-4,5-dinitroimidazole (2b). The latter compound proved to be effective against Candida sake S-1 (in contrast to inactive 5FC).

Induction of CYPIA by the N-imidazole derivative, 1-benzylimidazole

Xenobiotics can induce cytochrome P4501A (CYP1A) by ligand binding to the aryl hydrocarbon receptor (AhR). Typical AhR ligands are polycyclic aromatic compounds with planar molecular conformation. The present work investigated the ability of the N-imidazole derivative, 1-benzylimidazole (BIM), to induce CYP1A in rainbow trout hepatocytes. Benzylimidazole increased hepatocellular CYP1A catalytic activity (determined as 7-ethoxyresorufin-O-deethylase [EROD] activity) and CYP1A mRNA in a concentration-dependent way. Computational studies on the molecular structure of BIM indicated that the energetically most stable BIM conformer has the imidazole ring and the phenyl ring in different planes, i.e., does not take a planar conformation. This property of BIM does not agree with the structural requirements of a typical AhR ligand. In line with this observation, we found that the AhR antagonist, alpha-naphthoflavone (alphaNF), was not able to inhibit BIM induction of EROD activity and CYP1A mRNA, although it inhibited the induction of CYP1A by the prototypic AhR ligand, alpha-naphthoflavone (betaNF). The results suggest that transcriptional activation of CYP1A by the N-imidazole derivative, BIM, is not mediated through direct ligand binding to the AhR.

COUPLING OF NU(NH…N) VIBRATIONS WITH THE GAMMA(NH…N) OVERTONE IN SOLID IMIDAZOLE DERIVATIVES

The IR spectra of a number of imidazole derivatives were studied in the solid state at room and liquid nitrogen temperatures. The bands ascribed to stretching and out-of-plane deformation vibrations of NH groups involved in strong NH…N hydrogen bonds were analysed. The energy of this bond reflected in the position of the nu(NH…N) band changes over a broad range so that it was possible to investigate band shaping due to the overlap with the overtone band of the gamma(NH…N) mode. The correlation between the gamma(NH…N) and nu(NH…) frequencies shows that the gamma(NH…N) value for strong NH…N bridges only slightly depends on nu(NH…N).

Crystallization Processes through Self-assembled Materials Dependent on the Substituents of Tetrapodal Adamantanes

Three tetrapodal tetraaryladamantanes bearing imidazole derivatives exhibit unique self-assembly and crystallization behaviors, including hollow spherical aggregation, a morphological change by fusion events, and phase transition into crystals. In crystals, the packing and arrangements of tetrapodal adamantanes are subject to the substituents of imidazole derivatives in the molecules.

Synthesis of imidazole derivatives and the spectral characterization of the binding properties towards human serum albumin

Small molecular drugs that can combine with target proteins specifically, and then block relative signal pathway, finally obtain the purpose of treatment. For this reason, the synthesis of novel imidazole derivatives was described and this study explored the details of imidazole derivatives binding to human serum albumin (HSA). The data of steady-state and time-resolved fluorescence showed that the conjugation of imidazole derivatives with HSA yielded quenching by a static mechanism. Meanwhile, the number of binding sites, the binding constants, and the thermodynamic parameters were also measured; the raw data indicated that imidazole derivatives could spontaneously bind with HSA through hydrophobic interactions and hydrogen bonds which agreed well with the results from the molecular modeling study. Competitive binding experiments confirmed the location of binding. Furthermore, alteration of the secondary structure of HSA in the presence of the imidazole derivatives was tested.

Induction of cytochrome P4501A (CYPIA) by clotrimazole, a non-planar aromatic compound. Computational studies on structural features of clotrimazole and related imidazole derivatives

The classical pathway for induction of cytochrome P4501A (CYP1A) by xenobiotics is ligand binding to the aryl hydrocarbon receptor (AhR). High-affinity AhR ligands are planar polyaromatic molecules such as the prototypic ligand, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). The present work investigated the ability of the imidazole derivative, clotrimazole [ 1-(2′ chlorotrityl)imidazole, CLO], to induce CYP1A in cultured rainbow trout (Oncorhynchus mykiss) hepatocytes at the catalytic activity (determined as 7-ethoxyresorufin-O-deethylase, EROD) and at the transcriptional level. CLO resulted in a significant increase of hepatocyte EROD activity and CYP1A mRNA at a concentration of 1.56 muM. Computational studies on the molecular structure of CLO show that CLO is unlikely to take a planar conformation. Further indications that CLO does not behave like a planar AhR ligand come from the experimental observation that co-incubation of trout hepatocytes with CLO and the AhR antagonist, alpha-naphthoflavone (alpha-NF), did not result in an inhibition of CLO induction of CYP1A mRNA, whereas alpha-NF was able to inhibit CYP1A induction by the prototpyic, planar AhR ligand, beta-naphthoflavone. The experimental findings on CLO agree with previous results obtained for another non-planar imidazole derivative, 1-benzylimidazole (B1M). Further, computational studies showed that the non-planar imidazoles, BIM and CLO, are highly similar with respect to some electrostatic properties, namely the dipole moment and the molecular electrostatic potential (MEP). Overall our experimental and computational studies suggest that transcriptional activation of CYP1A by the imidazole derivatives CLO and BIM is mediated by a mechanism different to that of prototypic CYP1A inducers such as the planar AhR-ligands.

1,4-benzothiazine and 1,4-benzoxazine imidazole derivatives with antifungal activity: A docking study

We have recently described the synthesis and antifungal activity of a series of 1,4-benzothiazine and 1,4-benzoxazine imidazole derivatives that mainly showed in vivo activity against a murine experimental model of candidiasis but that very often lacked in vitro activity. Here, we report a docking study of a representative set of our molecules in a 3D model of CYP51 of Candida albicans (CA-CYP51). The model was constructed on the basis of the sequence homology relationship with the recently reported crystal structure of the CYP51 of Mycobacterium tuberculosis (MT-CYP51).
