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.

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.

Imidazole derivatives differentially destabilize the low pH conformation of lysozyme through weak electrostatic interactions

The structure-stability-function paradigm of proteins is highly governed by the pre-existence of repulsive and attractive non-covalent interactions. Electrostatic interactions with charged solvent molecules at the protein surface can contribute significantly to their stability. In order to unravel the electrostatic contributions of the positively charged species on a protein, we have studied the interactions of the imidazole derivatives (imidazole, histidine and histamine) with Hen Egg Lysozyme (HEL) in the pH range 4-2. At acidic pH, these compounds are reported to form charge transfer complexes (CTCs) with HEL through their protonated imidazole moiety with indole ring of protein’s tryptophan. Although literature is available on the molecular geometry and functional roles of CTCs, no knowledge is available on the electrostatic interactions and stability attenuation features of these complexes. To unravel the stability aspects of HEL upon binding to imidazole derivatives, we have performed pH dependent stability and structural studies using various biophysical techniques. Our results evidenced a stability attenuation of HEL in the pH range 4-2, both in its apo conformations and also in complex with imidazole derivatives. Moreover, at pH values 4 and 3 all these positive charged compounds destabilized HEL by a Tm of 57 degrees C, leaving the pH 2 conformation untouched. Structural analysis suggested that interactive networks of negatively charged Glu/Asp residues of the protein with CTC forming compounds is responsible for such differential stability attenuation. We believe that our results are handy to the researchers in deciphering the contributions of weak non-covalent interactions in biomolecular recognition processes.

Isoprene-Mediated Lithiation of 1-Alkylimidazoles: Chiral Induction of the Alkyl Substituent

The isoprene-mediated lithiation of imidazoles bearing a secondary alkyl substituent at the nitrogen (7, 8 and 13) and the subsequent nucleophilic addition to different electrophiles allows the preparation of the corresponding 2-functionalized imidazoles 10, 11 and 14. The presence of a stereogenic center in the alkyl substituent induces diastereoselection during the nucleophilic addition step with a prochiral electrophile (i.e. pivalaldehyde), producing the expected imidazole derivative with excellent overall yield, but low de (up to 26%).

Screening novel, potent multidrug-resistant modulators from imidazole derivatives

The overexpression of P-glycoprotein (P-gp) by tumor cells results in multidrug resistance (MDR) to structurally unrelated anticancer drugs. Combined therapy with MDR-related cytotoxins and MDR modulators is a promising strategy to overcome clinical MDR. This study was designed to screen potent MDR modulators from imidazole derivatives. Cytotoxicity was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The intracellular accumulation of doxorubicin (Dox) was detected by fluorescence spectrophotometry. The function of P-gp was examined by Rhodamine 123 accumulation detected with flow cytometry (FCM). Among imidazole derivatives, FG020326, FG020327, and FG020318 were found to possess three- to fourfold stronger reversal MDR activity than verapamil, a well-known positive MDR modulator. Imidazole derivatives significantly increased the Dox accumulation and inhibited P-gp function exhibited by the increase of Rhodamine accumulation in MDR cells. The fold reversal of MDR was relative with the increase of Rhodamine accumulation. FG020326, FG020327, and FG020318 showed potent MDR reversal activity in vitro. Their mechanism of MDR reversal is associated with the inhibition of P-gp function and the increase of anticancer accumulation. These results suggest FG020326, FG020327, and FG020318 are promising to further study and develop.
