N-substituted-2-butyl-5-chloro-3H-imidazole-4-carbaldehyde derivatives as anti-tumor agents against Ehrlich ascites tumor cells in vivo

A new series of N-substituted2-butyl-5-chloro-3H-imidazole-4-carbaldehyde derivatives were synthesized by using the different bioactive heteroaralkyl halides with 2-butyl-4-chloro-1H-imidazole-5-carbaldehyde in presence of powdered potassium carbonate in DMF medium. These compounds were screened for their antitumor activity. Our results show that treatment of imidazole derivatives inhibit proliferation EAT cells, decreases the ascites volume and increases the survivability of the animals in vivo. These compounds also inhibited the cellular proliferation of HUVEC cells in vitro by MTT assay. Further, these compounds could induce apoptosis, which is evident by the nuclear condensation of imidazole derivatives treated EAT cells in vivo by the cytological analysis. We have identified that pyrrolidine substituted imidazole derivative as potent anti-tumor compound. These inhibitors could represent as promising candidates for anticancer therapies, where the formation of peritoneal malignant ascites is a major cause of morbidity and mortality.

Physicochemical studies of bioactive heterocycles of some novel imidazole derivatives as sensitive NLO materials

Some novel imidazole derivatives were developed as highly sensitive chemisensors for transition metal ions. A prominent fluorescence enhancement was found in the presence of transition metal ions such as Hg2+, Pb2+,Cu2+, Zn2+, Co2+ and Fe2+ and this was suggested to result from the suppression of radiationless transitions from the n-pi* state in the chemisensors. By OFT calculation HOMO LUMO energies were calculated, the electric dipole moment (mu) and the hyperpolarizability (beta) of the investigated molecules have been studied experimentally and also theoretically. These synthesized molecules were found to have microscopic non-linear optical (NLO) behaviour with non-zero tensor components. (C) 2011 Elsevier B.V. All rights reserved.

Evaluation of non-toxic corrosion inhibitors for copper in sulphuric acid

The aim of this paper is to study influence of the molecular structure on the inhibiting properties of organic compounds in corrosion processes in acid media. The inhibiting efficiency of non-toxic imidazole derivatives on copper corrosion in sulphuric acid is investigated. The investigation is performed using electrochemical methods of potentiodynamic polarisation as well as gravimetric measurements. The results of the investigation show that the inhibiting properties of substituted imidazoles depend on molecular structure. The best protection (93%) is obtained by adding a phenyl ring to the imidazole structure. The values of standard free energies of adsorption, as calculated from the Freundlich isotherm, indicate that in the presence of sulphuric acid imidazole derivatives adsorb on copper by a physisorption-based mechanism.

Imidazole derivatives as angiotensin II AT1 receptor blockers: Benchmarks, drug-like calculations and quantitative structure-activity relationships modeling

We performed benchmark studies on the molecular geometry, electron properties and vibrational analysis of imidazole using semi-empirical, density functional theory and post Hartree-Fock methods. These studies validated the use of AM1 for the treatment of larger systems. Then, we treated the structural, physical and chemical relationships for a series of imidazole derivatives acting as angiotensin II AT1 receptor blockers using AM1. QSAR studies were done for these imidazole derivatives using a combination of various physicochemical descriptors. A multiple linear regression procedure was used to design the relationships between molecular descriptor and the activity of imidazole derivatives. Results validate the derived QSAR model.

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.

Phenanthro[9,10-d]imidazole with thiophene rings toward OLEDs application

A series of phenanthro [9,10-d]imidazole derivatives with thiophene units were synthesized using the Debus-Radziszewski reaction. A study of the optical, electrochemical and thermal properties of the new compounds was conducted. All derivatives were found to be thermally stable, with high melting temperatures (250-267 degrees C) and with the beginning of decomposition starting above 350 degrees C. They underwent the multistage electrochemical reduction. All phenanthro [9,10-d]imidazole derivatives were luminescent in solution and in solid state. In solution they emitted radiation with maximum emission band located at 414-461 nm with photoluminescence quantum yields in the range of 56%-64% in chloroform. As films they emitted blue light with Phi(PL) ranging from 12 to 23%. The possibility of applying one of the synthesized compound in optoelectronics devices was studied as well.

Imidazole derivatives as thermal latent catalyst for thiol-michael reaction thermosetting resins

Imidazole is an excellent nucleophilic initiator in thiol-Michael addition reaction of thiol and vinyl sulfone at room temperature. To delay the gelation of the monomer mixture, thermal latent curing agents based on imidazole are designed and the latency and curing efficiency towards thiol-vinyl sulfone system are evaluated. Ncarbonylated imidazole derivatives are non-nucleophilic towards Michael reaction with vinyl sulfone. However, during curing at elevated temperature ( > 80 degrees C), thiol monomer thiolyze imidazole derivative and the released imidazole acts as a nucleophilic initiator. It is found that the viscosity at room temperature of thiol-vinyl sulfone system with 2b or 2d imidazole derivatives increases slowly up to over 10 h, which permits sufficient time for processing such as mixing, degassing and injection into the mold. In the application of 2b or 2d in network polymerization of polythiol and divinyl sulfone, both catalysts have excellent curing ability with a 98% and 95% thiol conversion, respectively within 7 h at 100 degrees C. Using 2b or 2d, transparent thiol-vinyl sulfone resins with a refractive index of 1.57 and an Abbe number of 47.78 are successfully produced.
