Electrogenerated N-heterocyclic carbenes: N-functionalization of benzoxazolones

A simple electrochemical procedure for the N-acylation and N-alkylation of benzoxazol-2(3H)-ones has been set up via electrolysis of an ionic liquid containing a benzoxazolone followed by addition of saturated or unsaturated anhydrides or alkyl halides. The electrochemically induced N-functionalization of benzoxazol-2(3H)-ones works very well in all tested ionic liquids, avoiding the use of volatile organic solvents. The N-acyl and N-alkyl derivatives of benzoxazol-2(3H)-ones were isolated in good to excellent yields; moreover, the ionic liquid has been reused fivefold maintaining the high yield of the products.

Inhibitory effects of astaxanthin, beta-cryptoxanthin, canthaxanthin, lutein, and zeaxanthin on cytochrome P450 enzyme activities

Astaxanthin, beta-cryptoxanthin, canthaxanthin, lutein and zeaxanthin, the major xanthophylls, are widely used in food, medicine, and health care products. To date, no studies regarding the inhibitory effects of these xanthophylls on the nine CYPs isozymes have been reported. This study investigated the reversible and time-dependent inhibitory potentials of five xanthophylls on CYPs activities in vitro. The reversible inhibition results showed that the five compounds had only a weak inhibitory effect on the nine CYPs. Lutein did not inhibit the nine CYPs activities. Astaxanthin weakly inhibited CYP2C19, with an IC50 of 16.2muM; and beta-cryptoxanthin weakly inhibited CYP2C8, with an IC50 of 13.8muM. In addition, canthaxanthin weakly inhibited CYP2C19 and CYP3A4/5, with IC50 values of 10.9 and 13.9muM, respectively. Zeaxanthin weakly inhibited CYP3A4/5, with an IC50 of 15.5muM. However, these IC50 values were markedly greater than the Cmax values reported in humans. No significant IC50 shift was observed in the time-dependent inhibition screening. Based on these observations, it is unlikely that these five xanthophylls from the diet or nutritional supplements alter the pharmacokinetics of drugs metabolized by CYPs. These findings provide some useful information for the safe use of these five xanthophylls in clinical practice.

The potential of Epimedium koreanum Nakai for herb?drug interaction

Objectives: This study aims to investigate potential herb?drug interactions (HDI) of Epimedium koreanum Nakai. Methods: Human liver microsomes (HLMs) were used to determine the enzyme kinetics of the major human cytochrome P450s (CYPs). Inducible potential of E.?koreanum on CYP1A2, 2B6, 2C19 and 3A4 activities of human primary hepatocytes was also examined. Key findings: Ethanol extract of E.?koreanum showed direct inhibitory potency for CYP1A2 (IC50?=?121.8?mug/ml, Ki?=?110.7?¡À?36.8?mug/ml) and CYP2B6 (IC50?=?59.5?mug/ml, Ki?=?18.1?¡À?2.9?mug/ml). For CYP2C9, 2C19, 2D6, 2E1 and 3A4, only negligible effect was observed. Time-dependent (irreversible) inhibition by E.?koreanum was observed for CYP1A2 (KI?=?32.9?¡À?18.4?mug/ml, kinact?=?0.031?¡À?0.006?min?1). However, ethanol extract of E.?koreanum (1.5?150?mug/ml) did not change the activity or mRNA expressions for CYP3A4, 1A2, 2C19 and 2B6. Conclusions: The ethanol extract of E.?koreanum is not likely to cause HDI via inducing the major human CYPs. But the potential for interactions between E.?koreanum extract and substrates of CYP1A2 or 2B6 cannot be overlooked.

Bis-(benzothiazol-2-yl)-amines and their metal amides: A structural comparison in the solid state

Within this work, the field of amide ligand platforms for group 13 metal complexation, especially for Al(iii) is investigated in a synthetic as well as in a structural comparative approach. Starting from bis-heterocyclo methanides, which mimic the omnipresent nacnac ligand, the next enhancement in this class of ligands includes the exchange of the central methylene bridge by an amine nitrogen atom. With this modification three different sec. amines, each symmetrically substituted, could be synthesised as parent neutral benzothiazole containing ligand systems: (NCSC6H4)2NH (1), (4-MeNCSC6H3)2NH (2) and (4-OMeNCSC6H3)2NH (3). Apart from these compounds also a lithiated species and a row of group 13 metal complexes of the deprotonated ligands could be examined by applying single crystal X-ray diffraction analyses. In this course three new dimethyl aluminium containing complexes [Me2Al{(NCSC6H4)2N}] (4), [Me2Al{(4-MeNCSC6H3)2N}] (5) and [Me2Al{(4-OMeNCSC6H3)2N}¡¤AlMe3] (6) as well as two lithiated compounds [Li{(NCSC6H4)2N}]4 (7), [Li{(4-MeNCSC6H3)2N}]4 (8) were structurally and spectroscopically characterised. A subsequent structural comparison of 1-6 and 8 in the solid state shows that the parent ligand systems prefer a planar cis-trans alignment due to hydrogen bond formation. In contrast to that, the metallated species favour a planar but trans-trans or cis-cis alignment depending on the metal cation.

Structure-based development of nitroxoline derivatives as potential multifunctional anti-Alzheimer agents

Tremendous efforts have been dedicated to the development of effective therapeutics against Alzheimer’s disease, which represents the most common debilitating neurodegenerative disease. Multifunctional agents are molecules designed to have simultaneous effects on different pathological processes. Such compounds represent an emerging strategy for the development of effective treatments against Alzheimer’s disease. Here, we report on the synthesis and biological evaluation of a series of nitroxoline-based analogs that were designed by merging the scaffold of 8-hydroxyquinoline with that of a known selective butyrylcholinesterase inhibitor that has promising anti-Alzheimer properties. Most strikingly, compound 8g inhibits self-induced aggregation of the amyloid beta peptide (Abeta1-42), inhibits with sub-micromolar potency butyrylcholinesterase (IC50 = 215 nM), and also selectively complexes Cu2+. Our study thus designates this compound as a promising multifunctional agent for therapeutic treatment of Alzheimer’s disease. The crystal structure of human butyrylcholinesterase in complex with compound 8g is also solved, which suggests ways to further optimize compounds featuring the 8-hydroxyquinoline scaffold.
