Phosphine-free palladium-catalysed direct 5-arylation of imidazole derivatives at low catalyst loading

The regioselective 5-arylation of imidazole derivatives with aryl bromides using a low loading of a phosphine-free palladium catalyst gives a simple and economic access to the corresponding 5-arylimidazoles. The choice of the base and of the solvent was found to be crucial to form these products in high yields. Using KOAc as the base, DMAc as the solvent and only 0.5-0.01 mol % Pd(OAc)(2) as the catalyst, the target products were obtained in moderate to good yields with a wide variety of aryl bromides. Substituents Such as fluoro, trifluoromethyl, formyl, acetyl, propionyl, ester OF nitrile on the aryl bromide are tolerated. Sterically congested aryl bromides or heteroaryl bromides can also be employed. The nature of the substituents on the imidazole derivative has an important influence on the yields.

MOLECULAR DOCKING STUDIES OF IMIDAZOLE DERIVATIVES AS NEW CLASS OF HIV-1 PROTEASE INHIBITOR

The human immunodeficiency virus (HIV) infects the immune system that leads to immune deficiency. Acquired immunodeficiency syndrome (AIDS) is defined as the most advanced stages of HIV infection. It is defined by the occurrence of any of more than 20 opportunistic infections or HIV-related cancers. According WHO and UNAIDS estimation, 36.7 million people were living with HIV globally by the end of 2015. 2.1 million People became newly infected, and 1.1 million died of HIV-related causes at the same year. HIV-1 protease plays a vital role in the maturation of virus in order to produce the infectious viral particles.

Physicochemical studies of some novel Y-shaped imidazole derivatives – A sensitive chemisensor

Some novel Y-shaped imidazole derivatives were developed for highly sensitive chemisensors for transition metal ions. A prominent fluorescence enhancement was found in the presence of transition metal ions such as Hg2+, Pb2+ and Cu2+ and it is due to the suppression of radiationless transitions from the n-pi* state in the chemisensors. The HOMO-LUMO energies, electric dipole moment (mu) and the first-hyperpolarizability (beta) values of the investigated molecule have been studied theoretically which reveal that the synthesized molecules have microscopic non-linear optical (NLO) behaviour with non-zero values.

Synthesis and antimicrobial study of 2-amino-imidazole derivatives

A novel series of 2-amino-imidazole derivatives have been synthesized by conventional method from various di carbonyl compounds with substituted N-phenyl amides in presence of ammonium acetate and glacial acetic acid under reflux conditions with good yields. All the synthesized compounds have been characterized by IR, H-1 and C-13 NMR, mass and elemental analysis in full accordance with their depicted structures. The synthesized products have been screened for antimicrobial activity and the results reveal that introduction of amine at 2nd position of imidazole moiety enhances the antibacterial as well as antifungal activity.

Facile and Efficient Syntheses of a Series of N-Benzyl and N-Biphenylmethyl Substituted Imidazole Derivatives Based on (E)-Urocanic acid, as Angiotensin II AT1 Receptor Blockers

In the present work, a facile and efficient route for the synthesis of a series of N-substituted imidazole derivatives is described. Docking studies have revealed that N-substituted imidazole derivatives based on (E)-urocanic acid may be potential antihypertensive leads. Therefore, new AT1 receptor blockers bearing either the benzyl or the biphenylmethyl moiety at the N-1 or N-3 position, either the (E)-acrylate or the propanoate fragment and their related acids at the C-4 position as well as a halogen atom at the C-5 position of the imidazole ring, were synthesized. The newly synthesized analogues were evaluated for binding to human AT1 receptor. The biological results showed that this class of molecules possesses moderate or no activity, thus not always confirming high docking scores. Nonetheless, important conclusions can be derived for their molecular basis of their mode of action and help medicinal chemists to design and synthesize more potent ones. An aliphatic group as in losartan seems to be important for enhancing binding affinity and activity.

EVALUATION OF THE MUTAGENIC AND GENOTOXIC ACTIVITIES OF 48 NITROIMIDAZOLES AND RELATED IMIDAZOLE DERIVATIVES BY THE AMES TEST AND THE SOS CHROMOTEST

The mutagenic and genotoxic activities of 48 nitroimidazoles and related imidazole derivatives have been evaluated by using modified versions of the Ames test and the SOS Chromotest. Salmonella typhimurium tester strain TA 100 was used with and without metabolic activation in the Ames test and Escherichia coli tester Strain PQ 37 was used with and without metabolic activation in the SOS Chromotest. Including metronidazole and dimetridazole, 45 derivatives were mutagenic and genotoxic. The mutagenic potencies (MP) ranged from 0.127 to 53,717 revertants/nmol while the SOS induction powers (SOSIP) ranged from 0.00131 to 107 IF/nmol. The overall correlation between MP and SOSIP was r = 0.845 (n = 84) as calculated by linear regression analysis. A higher correlation was observed between MP and SOSIP without the S9 mix than with it. Among the imidazole derivatives, the 5-nitroimidazoles with a lactam ring at the 2-position showed the highest MP and SOSIP. The presence of a nitro group at the 5-position was critical for the mutagenicity and the genotoxicity of the derivatives. Substituents at the 1- and 2-positions were also found to modulate these activities.

Determination of inhibition effects of various imidazole derivatives on copper corrosion in 0.1M HCl media

In the present study the inhibitive behaviour of 1H-imidazole, 1-methyl imidazole, imidazolidin-2-one, 4-(imidazole-1-yl) acetophenone, 4-(imidazole-1-yl) phenol and L-hystidine on the corrosion of copper in 0 center dot 1 M HCl has been investigated by potentiodynamic polarisation and polarisation resistance techniques. Except for 2-imidazolidone, the tested imidazole derivatives were found to behave as cathodic inhibitors. 1-methyl imidazole, 4-(imidazole-1-yl) acetophenone, 4-(imidazole-1-yl) phenol and L-hystidine were adsorbed on copper surface according to Temkin isotherm model. By using semi-empirical quantum chemical methods, physical parameters such as charge on the heteroatoms of imidazole derivatives q(n), energies of highest occupied molecular orbital ( HOMO) and lowest unoccupied molecular orbital (LUMO) and dipole moments were calculated. Possible correlations between these calculated physical parameters and inhibitor efficiencies were considered. Finally, the mechanistic information relating to the inhibition process was elucidated.
