A novel 2,4,5-triaryl-substituted imidazole (IZCM-1) has been found to display distinct and specific fluorescence enhancement upon binding to parallel G-quadruplexes. Such a sensitive and topology-specific probe is able to light up without affecting the topology or thermal stability of the G-quadruplex sample. Thus, these advantages distinguish IZCM-1 from other G-quadruplex probes.

An efficient synthesis of 1,3-diaryl-4-halo-1H-pyrazoles was achieved. The synthesis involves the [3 + 2] dipolar cycloaddition of 3-arylsydnones and 2-aryl-1,1-dihalo-1-alkenes. The process proceeds smoothly in moderate to excellent yields. 1,3-Diaryl-4-halo-1H-pyrazoles are found to be important intermediates that can easily be converted into 1,2,5-triaryl-substituted pyrazoles via Pd-catalyz...

Low-temperature studies of the simple variously substituted imidazole types 4-phenyl-1H-imidazole, C9H8N2, 1-benzyl-1Himidazole, C10H10N2, and 1-mesityl-1H-imidazole, C12H14N2, extend comparisons between parent imidazole species and their derivatives, the pronounced double-bond localization opposite the substituted N atom common to simple neutral species being redistributed aromatically on prot...

The inability to meet the desired outcomes of anticancer treatment and decrease in success bacterial fungal infections accelerated research these areas. Our group has conducted numerous studies, especially on benzimidazole ring systems’ antiproliferative antimicrobial activities. In this study, activity compounds was tested against A549, A498, HeLa, A375, HepG2 cancer cell lines by MTT assay. A...

Mono- and binuclear arene–ruthenium(II) complexes with imidazole-containing ligands were prepared by the reaction of (L1 = bis(imidazole-1-yl)methane; ImH 1H-Imidazole; BImH 1H-Benzimidazole) [(p-cym)Ru(µ-Cl)2]2 dimers. When bis(imidazole-1-yl)methane reacted in methanol, a complex type [Ru2(L1)2(p-cym)2Cl2]Cl2 (2) cyclic structure was synthesized, whereas using acetonitrile as solvent under sa...

This study aimed to use an existing ligand (imidazole)-assisted 1H-nuclear magnetic resonance (1H-NMR) spectroscopy protocol determine sulfate content of seaweed sulfated saccharides. Twenty samples – spanning nine species and multiple geographic locations were analyzed. Extracts obtained by immersing freeze-dried seaweeds in boiling water, followed alginate precipitation. Remaining supernatant...

The asymmetric unit of the crystal structure of the title compound, [Cd(2)Cl(4)(C(5)H(8)N(2))(3)](n), contains two Cd(II) cations, three 1-ethyl-1H-imidazole ligands, and four Cl(-) anions. The two Cd(II) atoms have quite different coordination environments: one is octa-hedrally coordinated by four Cl atoms and two N atoms from two 1-ethyl-1H-imidazole ligands, and the second is in a severely d...
