Arabinogalactan propargyl ethers: Au-catalysed hydroamination by imidazols

A method for the synthesis of pharmacologically prospective arabinogalactan (AG) imidazole- and benzimidazole derivatives in a yield of up to 97 % via Au(III)-catalyzed hydroamination of AG propargyl ethers has been developed. It is found that in the presence of 5 mol% HAuCl4 and 10-fold excess imidazole relative to the propargyl groups, the hydroamination successfully competes with cross-linking processes to afford products soluble in DMSO and aqueous HCl solutions (degree of substitution of imidazolylpropenyl fragments 0.5-1.8, yield 62-97 %). It is established that under the conditions of hydroamination Au(III) is reduced to give mainly Au(0) and minor amounts of Au(I), which are contained in AG imidazole derivatives as particles of 190-640 nm in size. Hydrochlorides of Au-containing AG imidazole derivatives show high bacteriostatic activity with respect to test gram-positive microorganisms and thus confirming their prospects as new AG-derived bioactive agents.

A green, facile approach for the multicomponent synthesis of bioactive spiro[indoline-3,7 ‘-pyrrolo[1,2-c]imidazole] derivatives

An efficient synthesis of spiro[indoline-3,7’-pyrrolo[1,2-c]imidazole] is achieved through a three-component reaction of isatins, malononitrile, and hydantoin/2-thiohydantoin in water catalysed by NaHCO3.

Influence of functionalised multiwalled carbon nanotubes with imidazole derivative and thiosemicarbazide on MKN45 and SW742 cancer cells

Carboxylated multiwall carbon nanotubes (MWCNT-COOH) were first modified by an imidazole derivative, 2-amino-1-methyl-5-(3,4,5-trimethoxybenzylidene)-1H-imidazol-4(5H)-one, to form a MWCNT-Im and then by thiosemicarbazide to produce MWCNT-Py. All products were characterised by Fourier transform infrared spectroscopy, Raman spectroscopy, scanning electron microscope, energy dispersive X-ray spectroscopy, solubility test, thermogravimetric analysis, derivative thermogravimetric and cellular investigations. These functionalisations have been chosen due to active sites of C=C and carbonyl groups in MWCNT-Im and NH2 and sulphur groups in MWCNT-Py, which might be used as functional materials in future. Toxicity of these samples was evaluated with human gastric (MKN45) and colon (SW742) cancer cells, and the killed cell numbers were measured by reduction in living cells with 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyltetrazolium bromide (MTT) after 48 h of cell culture experiments. Cellular investigations showed high toxicity of modified MWCNTs on the gastric cancer cells compared to colon cells. In addition, MWCNT-Py sample indicated the highest toxicity for both cancer cells compared to other samples.

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.

Synthesis, spectral studies and solvatochromic analysis of novel imidazole derivatives

Bioactive imidazole derivatives were synthesized and characterized by spectral techniques. The photophysical properties of imidazole derivatives were studied in several solvents. The observed spectral shift is attributed to a loss of planarity in the excited state provided by the non-co-planarity of the aryl rings attached to C(2) and N(1) atoms of the imidazole ring. The observed solvatochromic shifts were analyzed in detail by Kamlet-Taft and Catalan parameters. The interaction between bioactive imidazole derivative and bovine serum albumin (BSA) was also investigated. (C) 2012 Elsevier B.V. All rights reserved.

A molecular probe based on pyrimidine imidazole derivatives for stable super-resolution endoplasmic reticulum imaging in living cells

Multi-functional florescent dyes capable of acting as molecular probes in living systems under two-photon microscopy, as well as super-resolution nanoscopy, are of great interest. Herein, a novel donor–acceptor (D–A) type pyrimidine imidazole derivative with a flexible alkyl chain molecule (EX-1) has been efficiently synthesized through improved Knoevenagel condensation with high yield and relatively large 2PA cross-sections. Furthermore, a cytotoxicity assay and photo-resistance evaluation indicated that such small organic dyes could not only effectively target the endoplasmic reticulum in living cells, but also reveal its ultrastructure under stimulated emission depletion (STED) nanoscopy.
