Synthesis and biological evaluation of 1,2,4,5-tetrasubstituted imidazoles

Tetrasubstituted imidazoles were synthesized in high yields via the four-component reaction of aromatic aldehydes, amines, substituted benzils and ammonium acetate catalyzed by a porous CeO2 nanorod. Their anti-cancer activities on the Huh-7 hepatocellular carcinoma cell and antibacterial activities on four bacterial species (wild-type Escherichia coli, wild-type Staphylococcus aureus, Pseudomonas aeruginosa PAM1032 and Escherichia coli-NMD-1) in vitro were evaluated. One compound (5p) was screened out because of its high inhibition rate on all four bacterials at 100 μg/mL. Three products (5p, 5t and 5y) showed a high inhibition rate on the Huh-7 hepatocellular carcinoma cell at 10 μg/mL. The results indicated their potential in new drug development.

Triarylimidazole redox catalysts: Electrochemical analysis and empirical correlations

A series of triarylimidazoles was synthesized and characterized electrochemically. The synthetic route is general, providing a pathway to 30 redox mediators that exhibit a > 700 mV range of accessible potentials. Most of the triarylimidazoles display three oxidation peaks where the first redox couple is quasi-reversible. The electronic character of the substituents affects the oxidation potential. This is exemplified by a linear correlation between the first oxidation potential and the sum of the Hammett σ+ substituent constants, as well as with a series of calculated ionization potentials. We close by putting forward a rule of thumb stating that for a given mediator, the upper limit of accessible potentials can be extended by at least 500 mV beyond the largest recorded value. A rationale, the conditions under which the rule is likely to apply, and an example are provided.

Synthesis of 2-substituted-N-[4-(1-methyl-4,5-diphenyl-1H-imidazole-2-yl) phenyl] acetamide derivatives and evaluation of theiranticancer activity

In the present study 18 novel imidazole-(benz)azole and imidazoleepiperazine derivatives were synthesized in order to investigate their probable anticancer activity. The structures of the compounds were confirmed by IR,1H NMR and EI-MS spectral data. Cytotoxicity (MTT),analysis of DNA synthesis and detection of apoptotic DNA assays were applied to determine anticancer activity of the compounds against colon (HT-29) and breast (MCF-7) carcinoma cell lines. Most of the compounds,showed greater activity against HT-29 cells than MCF-7 cells. Some of them indicated considerable cytotoxicity against both of the carcinogenic cell lines. However,their inhibitory activity on DNA synthesis was relatively poor. Anticancer activity screening results revealed that 11,12 and 13 were the most active compounds in the series. They exhibited significant cytotoxicity against both of the carcinogenic cell lines and caused DNA fragmentation of the HT-29 cells.

Synthesis and?antibacterial activity of?various substituted s-triazines

Series of substituted-s-triazines (1-22) were synthesized and evaluated for their in vitro antibacterial activity against six representative Gram-positive and Gram-negative bacterial strains. Many compounds have displayed comparable antibacterial activity

New class of imidazoles incorporated with thiophenevinyl conjugation pathway for robust nonlinear optical chromophores

A new series of thermally stable heterocyclic imidazole-based nonlinear optical chromophores has been developed. These chromophores possess a thiophene based stilbene conjugation pathway with a nitro acceptor group attached to the phenyl end. This feature leads to robust chromopores with high thermal stability and enhanced molecular nonlinearity.
