Conformation study on recognition of imidazole derivatives by chiral amino acids linked porphyrins

Chiral recognition is an attractive subject in the area of host-guest chemistry. Conformation study is performed to understand chiral recognition of zinc(II) porphyrin with imidazole derivatives on a molecular level. The molecular recognition of three novel chiral zinc porphyrin(1-3) with four types of imidazole derivatives was studied. The conformation searching of this host-guest system was studied by using simulated annealing method on the basis of Tripos force field. The different minimal energy conformation of imidazole combind with porphyrin was studied. The quantum chemistry calculation was performed to calculate the single-point energies of the host-guest system. The minimal energy conformation of ZnT(o-BocAla)APP (3)-Im showed that Im attaching from the singleside chain of the host had the reasonable configuration than that from the three-side chain. The former also had the lower energy than the latter. And the quantum chemistry calculation results of orbital energy, DeltaE(L-H), and atomic net charge revealed the same way. The results illumate that combination oriention of the host-guest system is the single chain of the hosts.

Facile synthesis of optically active imidazole derivatives

Five optically active imidazole derivatives have been synthesized via a facile 4-step reaction sequence starting from commercially available and inexpensive N-Cbz amino acids. While microwave assisted condensation was unsuccessful, the condensation of the corresponding alpha-bromoketones with formamidine acetate in liquid ammonia was revealed to be a useful method for the synthesis of such imidazole derivatives. The derivatives thus prepared are structurally-related to histamine.

Synthesis, NMR Spectral and DFT Studies of Styryl Imidazole Derivatives-Nano-SiO2 as an Efficient Catalyst

A series of novel styryl imidazole derivatives has been designed and synthesized using nano-SiO2 as an efficient catalyst. Synthesized compounds have been characterized by H-1 and C-13-NMR spectral studies. The significant features of this nanocatalyst are high product yield, short reaction times and a vast range of substrates usage. Proton and C-13 chemical shifts of the synthesized compounds were calculated. Single crystal XRD analysis has been carried out to confirm the structure of MDPI (1-(3-methoxyphenyl)-4, 5-dimethyl-2-phenyl-1H-imidazole) and it shows the imidazole ring is essentially planar and triclinic crystal. Optimization of compound MDPI was performed by DFT at B3LYP/ 6-31G (d, p) using Gaussian-03. Imidazole derivatives were used to construct highly sensitive fluorescent chemosensors for sensing of metal ions.

Synthesis, antimicrobial and docking study of three novel 2,4,5-triarylimidazole derivatives

A novel series of 2-[5-(4-substituted phenyl)furan-2-yl]-4,5-diphenyl-1H-imidazole derivatives (2a-c) were synthesized and characterized using IR, H-1 NMR and GC-MS spectra. These compounds were in vitro screened against several bacterial species as well as Candida albicans, the common fungi species and found exhibiting moderate to potent activity. Docking of synthesized compounds against glucosamine-6-phosphate synthase, the target enzyme for the antimicrobial agents, was achieved to explore and explain the interactions of the discovered hits within the amino acid residues of the enzyme binding pocket. The docking results enhanced the activity of new derivatives as promising antimicrobial agents. (C) 2013 Production and hosting by Elsevier B.V. on behalf of King Saud University.

Synthesis and biological evaluation of 3-(azolylmethyl)-1H-indoles and 3-(alpha-azolylbenzyl)-1H-indoles as selective aromatase inhibitors

This present study identifies a number of azolyl-substituted indoles as potent inhibitors of aromatase. In the sub-series of 3-(azolylmethyl)-1H-indoles, four imidazole derivatives and their triazole analogues were tested. Imidazole derivatives 11 and 14 in which the benzyl moiety was substituted by 2-chloro and 4-cyano groups, respectively, were the most active, with IC50 values ranging between 0.054 and 0.050 mu M. In the other sub-series, eight 3-(alpha-azolylbenzyl)-1H-indoles were prepared and tested. Compound 30, the N-ethyl imidazole derivative, proved to be an aromatase inhibitor, showing an IC50 value of 0.052 mu M. All target compounds were further evaluated against 17 alpha-hydroxylase/C17,20-lyase to determine their selectivity profile.

Remarkable Improvement Achieved by Imidazole Derivatives in Ruthenium-Catalyzed Hydroesterification of Alkenes Using Formates

Imidazole derivatives are revealed to be effective ligands in the Ru-catalyzed hydroesterification of alkenes using formates, affording one-carbon-elongated esters in high yields. Further, intramolecular hydroesterification was successfully performed to give lactones for the first time. Imidazole derivatives can contribute to promote the reaction as well as to suppress the undesired decarbonylation of formate. Toxic CO gas, a directing group, and large excess alkenes are not required.

An iminophosphorane-based approach for the synthesis of spiropyrrolidine-imidazole derivatives

A method based on the reaction of an E-phosphazide, an intermediate in the Staudinger reaction between triphenylphosphine and an azide, with heterocumulenes allows the one-pot, two-component synthesis of a number of pyrrole-imidazole derivatives. The procedure, which involves sequential treatment of the appropriate a-azido ester with triphenylphosphine and isocyanate leads to the hydantoin product after aqueous work-up. The cyclization conditions can also be adapted for the synthesis of thiohydantoins by using isothiocyanates. These hybrids pyrrole-thiohydantoins undergo a novel oxidative spirocyclization by action of DDQ to give a tricyclic derivative (pyrrole-pyrrolidine-imidazole), which displays an interesting cytotoxic activity.
