Studies on interaction between an imidazole derivative and bovine serum by spectral methods

The interaction between a trifluoromethyl substituted imidazole derivative 2-(4-(trifluorometh yl)phenyl)-1-phenyl-1H-imidazo[4,5-f] [1,10] phenanthroline (tfmppip) and bovine serum albumin (BSA) was investigated by solution spectral studies. The observed experimental result shows that the imidazole derivative has strong ability to quench the fluorescence of BSA by forming complex which is stabilized by electrostatic interactions. The effective quenching constants (k(sv)) were 2.79 x 10(4), 2.51 x 10(4), and 2.32 x 10(4) at 301, 310 and 318 K respectively. The Stern-Volmer quenching constant (K-sv), binding site number (n), apparent binding constant (K-A) and corresponding thermodynamic parameters (Delta G, Delta H and Delta S) were calculated. The distance between the donor (BSA) and acceptor (tfmppip) was obtained according to fluorescence resonance energy transfer (FRET). Conformational changes of BSA were observed from synchronous fluorescence technique. The effect of metal ions such as Cu2+, Zn2+, Ca2+, Mg2+, Ni2+, Co2+ and Fe2+ on the binding constants between the imidazole derivative and BSA were also studied. (C) 2012 Elsevier B.V.

Synthesis of maleimide modified imidazole derivatives and their application in one-component epoxy resin systems

A series of novel maleimide modified imidazole derivatives were successfully synthesized through the addition reaction between N-(4-hydroxyphenyl) maleimide (HPM) and imidazole compounds with 1-position N-H bond. The maleimide modified imidazole derivatives were blended with epoxy resin (EP) to evaluate their reactivity and thermal latency. Compared with the common EP/imidazoles systems, the curing exothermic interval of the EP systems containing maleimide modified imidazole derivatives shifted to higher temperature regions. Moreover, the EP systems containing maleimide modified imidazole derivatives had much longer pot life under room temperature. The enhanced latency of maleimide modified imidazole derivatives was attributed to the strong electron withdrawing effect of maleimide group, which reduced the nucleophilicity of imidazole moiety. Notably, the maleimide modified imidazole derivatives regained fast curing ability towards EP by overcoming the curing reaction energy barrier under heating condition. (C) 2018 Elsevier B.V.

CALCULATION OF TAUTOMER PREFERENCE FOR RIGID IMIDAZOLE DERIVATIVES

The tautomeric preference of rigid imidazole derivatives has been analyzed theoretically from molecular orbital calculations ab initio. The present results indicate that the reduced potencies exhibited by imidazolylphenylene analogues of cimetidine and metiamide at the H2-receptor are consistent with those hypotheses that defined the N3-H tautomer of the monocation as the only recognizable species in this class of histamine H2-ligand. However, our results suggest that the 4-methylimidazolylphenylene analogue of cimetidine could be an effective histamine H3-antagonist.

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.
