PH-Responsive N-heterocyclic carbene copper(i) complexes: Syntheses and recoverable applications in the carboxylation of arylboronic esters and benzoxazole with carbon dioxide

A pH-controlled monophasic/biphasic switchable system has been developed as a green and novel strategy for homogeneous catalyst recycling, which has been successfully applied to the Cu-NHC-catalyzed carboxylation of organoboronic esters and benzoxazole with carbon dioxide. Additionally, the present strategy could also be extended to the Ag-NHC-catalyzed carboxylation of terminal alkyne. The tertiary amine-functionalized catalysts could be used for at least four times with a slight loss of activity.

Indoles via Knoevenagel-Hemetsberger reaction sequence

A series of substituted indoles have been synthesized by the sequential reaction of aromatic aldehydes with ethyl azidoacetate in the presence of sodium ethoxide to form the corresponding ethyl alpha-azido-beta-arylacrylates (Knoevenagel process) followed by a solvent mediated thermolysis (Hemetsberger process). The isolated yields of the ethyl alpha-azido-beta-arylacrylates were significantly increased when employing the sacrificial electrophile ethyl trifluoroacetate. 1H NMR and coupled 1H-13C NMR analysis of the ethyl alpha-azido-beta-arylacrylates indicate that the condensation is stereospecific – only the Z-isomer could be detected. Solvent mediated thermal treatment of the meta-substituted ethyl alpha-azido-beta- arylacrylates resulted in the formation of both the 5- and 7- substituted indoles – the 5-regioisomer being slightly favored over the 7-regioisomer. Analogous thermal treatment of (2Z, 2Z?)-diethyl 3,3?-(1,3- phenylene)bis(2-azidoacrylate) and (2Z, 2Z?)-diethyl 3,3?-(1,4- phenylene)bis(2-azidoacrylate) exclusively produced pyrroloindoles, diethyl 1,5-dihydropyrrolo[2,3-f]indole-2,6-dicarboxylate and diethyl 1,5-dihydropyrrolo[2,3-f]indole-2,6-dicarboxylate, respectively. Results are also reported which indicate that the alpha-azido-beta-arylacrylates can be used in the subsequent Hemetsberger indolization process without prior purification.

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.

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.

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.
