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.

IMIDAZOLIUM YLIDES: CYCLOADDITION versus HYDROLISIS

Reactions of imidazolium ylides with dimethyl acetylenedicarboxylate in polar solvents (methanol) were studied. In the competition between cycloaddition versus hydrolysis, the last one prevails leading to base heterocycle, diene structures and benzoate esters. A feasible reaction mechanism is presented. When fused pyrrolo-imidazole derivatives are desirable to be obtained, polar solvents should be avoided.

Formation of hydrogen-bonded chains between strong N-base and N-H acids – a FTIR study

Mixtures of imidazole derivatives with the strong base 7-methyl-1,5,7-triazabicyclo[4.4.0]dec-5-ene (MTBD) were studied by FTIR spectroscopy as a function of the imidazole derivative:MTBD ratio. In the case of complexes of MTBD with the lowest acidic imidazole only molecular complexes are found. This is true in the chloroform solutions as well as in the acetonitrile solutions. With increasing acidity of the imidazoles in both solvents more and more polar structure of the complexes is found. In chloroform the polar structure predominates and the proton polarizability in the chains remains weak. In the acetonitrile solution the complexes dissociate. If more imidazole molecules are present one observes large proton polarizability of the negatively charged structurally symmetrical imidazole chains. (C) 1998 Elsevier Science B.V.

1H-Benzo[d]Imidazole Derivatives Affect MmpL3 in Mycobacterium tuberculosis

1H-benzo[d]imidazole derivatives exhibit antitubercular activity in vitro at a nanomolar range of concentrations and are not toxic to human cells, but their mode of action remains unknown. Here, we showed that these compounds are active against intracellular Mycobacterium tuberculosis. To identify their target, we selected drug-resistant M. tuberculosis mutants and then used whole-genome sequencing to unravel mutations in the essential mmpL3 gene, which encodes the integral membrane protein that catalyzes the export of trehalose monomycolate, a precursor of the mycobacterial outer membrane component trehalose dimycolate (TDM), as well as mycolic acids bound to arabinogalactan. The drug-resistant phenotype was also observed in the parental strain overexpressing the mmpL3 alleles carrying the mutations identified in the resistors. However, no cross-resistance was observed between 1H-benzo[d]imidazole derivatives and SQ109, another MmpL3 inhibitor, or other first-line antitubercular drugs. Metabolic labeling and quantitative thin-layer chromatography (TLC) analysis of radiolabeled lipids from M. tuberculosis cultures treated with the benzoimidazoles indicated an inhibition of trehalose dimycolate (TDM) synthesis, as well as reduced levels of mycolylated arabinogalactan, in agreement with the inhibition of MmpL3 activity. Overall, this study emphasizes the pronounced activity of 1H-benzo[d]imidazole derivatives in interfering with mycolic acid metabolism and their potential for therapeutic application in the fight against tuberculosis.
