Chelidonium majus L.: Components with in vitro Affinity for the GABAA Receptor. Positive Cooperation of Alkaloids

The influence of an ethanolic dry extract of Chelidonii herba on the GABAA receptor has been studied in vitro. In the presence of 90 mug/assay a positive cooperation was induced for [3H]muscimol accompanied by an increase of the specific binding (115%) while 160 mug/assay exerted a 50% inhibition of the specific binding of the radioligand [3H]muscimol. The quantitative determination of the Chelidonium alkaloids by HPLC together with the evaluation of the radioreceptor assays of the pure alkaloids revealed that the allosteric modulation of the GABAA receptor is mainly due to protopine. The small amounts of allocryptopine and stylopine assumingly support the action of protopine. Protopine, stylopine, and allocryptopine do not influence the specific binding of [3H]flunitrazepam. Thus, the positive cooperative modulation of the GABAA receptor is not based on an interaction of these alkaloids with the benzodiazepine receptor. The specific [3H]muscimol binding was inhibited only by chelerythrine and sanguinarine with IC50 values of 25 muM and 39 muM, respectively. The content of chelerythrine and sanguinarine in the ethanolic dry extract of Chelidonii herba is 500 or even 1000 times too low to account for the observed interference with the GABAA receptor activity. Thus, the alkaloids are not responsible for the inhibitory action on the GABAA receptor at higher concentrations of the ethanolic dry extract.

Synthesis and characterization of alternating copolymers of thiophene-containing N-phenyl maleimide and styrene by photoinduced radical polymerization and their use in electropolymerization

A novel N-(4-(3-thienyl methylene)-oxycarbonylphenyl) maleimide (MBThi) monomer was synthesized by the esterification reaction of maleimidobenzoic acid (MBA) with 3-thiophene methanol. Photoinduced radical polymerization was employed to prepare the alternating copolymers of MBThi with styrene (St) at room temperature using omega,omega-dimethoxy-omega-phenylacetophenone (DMPA) as photoinitiator. Different copolymerization conditions were examined to estimate the influence of the used solvents and comonomers’ total molar concentration on the conversion, the number-average molecular weight (M n), and polydispersity index (Mw/Mn) of the resulting polymers. Thermal behavior of the alternating copolymers (PSt-alt-MBThi) was also investigated by thermogravimetrical analysis (TGA) and differential scanning calorimetry. Moreover, the obtained alternating copolymers were employed in electropolymerization experiments and random conjugated graft copolymers with thiophene or pyrrole were synthesized through their pendant thienyl groups. These polymers were characterized by cyclic voltammetry (CV), FTIR and scanning electron microscopy (SEM). Conductivity measurements were carried out by the four-probe technique.

Development of a merged conjugate addition/oxidative coupling sequence. Application to the enantioselective total synthesis of metacycloprodigiosin and prodigiosin R1

A merged conjugate addition/oxidative coupling sequence that represents an efficient strategy for preparing structurally diverse pyrroles has been developed. Success of the method hinged upon the controlled oxidative coupling of unsymmetrical silyl bis-enol ether intermediates, formed by the 1,4-addition of a Grignard reagent with subsequent enolate trapping by a (chloro)silylenol ether. The process was applied to the first enantioselective syntheses of the biologically active pyrrolophane natural products, metacycloprodigiosin and prodigiosin R1.

Bioconjugation and Fluorescence Labeling of Iron Oxide Nanoparticles Grafted with Bromomaleimide-Terminal Polymers

Iron oxide nanoparticles have been widely applied in biomedical applications for their unique physical properties. Despite the relatively mature synthetic approaches for iron oxide nanoparticles, surface modification strategies for obtaining particles with satisfactory biofunctionality are still urgently needed to meet the challenge of nanomedicine. Herein, we report a surface modification and biofunctionalization strategy for iron oxide-based magnetic nanoparticles based on a dibromomaleimide (DBM)-terminated polymer with brushed polyethylene glycol (PEG) chains. PEG acrylate and phosphonate monomers, serving as antibiofouling and surface anchoring compartments for iron oxide nanoparticles, were incorporated utilizing a novel DBM containing reversible addition-fragmentation chain transfer (RAFT) agent. The particles prepared through this new surface architecture possessed high colloidal stability in a physiological buffer and the capacity of covalent conjugation with biomolecules for targeting. Cell tracking of the molecular probes was achieved concomitantly by exploiting DBM conjugation-induced fluorescence of the nanoparticles.

Catalytic, Cascade Ring-Opening Benzannulations of 2,3-Dihydrofuran O,O- and N,O-Acetals

An Al(OTf)3-catalyzed intramolecular cascade ring-opening benzannulation of 2,3-dihydrofuran O,O- and N,O-acetals is described. The cascade sequence involves the dihydrofuran ring-opening by acetal hydrolysis, an intramolecular Prins-type cyclization, and aromatization to generate an array of benzo-fused (hetero)aromatic systems in up to 95 % yield. This method represents the first example of dihydrofuran acetal usage in benzannulation reactions. The approach provides excellent regiocontrol based on the choice of alkenes used to form the requisite dihydrofuran acetals.

Intracellular accumulation as an indicator of cytotoxicity to screen hepatotoxic components of chelidonium majus L. By LC-MS/MS

A novel strategy was developed to identify hepatotoxic compounds in traditional Chinese medicines (TCMs). It is based on the exposure of HL-7702 cells to a TCM extract, followed by the identification and further determination of potential hepatotoxic compounds accumulated in the cells by liquid chromatography-tandem mass spectrometry (LC-MS/MS). As a case study, potential hepatotoxic components in Chelidonium majus L. were screened out. Five alkaloids (sanguinarine, coptisine, chelerythrine, protopine, and chelidonine) were identified by LC-MS/MS within 10 min, and their intracellular concentrations were first simultaneously measured by LC-MS/MS with a run time of 4 min. Acell viability assay was performed to assess the cytotoxicity of each alkaloid. With their higher intracellular concentrations, sanguinarine, coptisine, and chelerythrine were identified as the main hepatotoxic constituents in Ch. majus. The study provides a powerful tool for the fast prediction of cytotoxic components in complex natural mixtures on a high-throughput basis.

Pyrrolidino enaminones structural related to gyrase inhibitors: Synthesis, cyclization and pharmacological activity

The synthesis and stereochemical characteristics of pyrrolidino enaminones with structural analogy to quinolone antibacterial agents are reported. Retro-aldol reaction of the esters 7 is observed under all conditions of hydrolysis, the enzyme catalyzed reaction also does not yield the corresponding acids. In contrast to clinically used quinolones exemplary tests with monocyclic esters of type 7 and the tricyclic derivative 10 indicate low or no antibacterial activity. Additionally to the lack of the carboxylic acid function the enaminones 7 differ from quinolones in stereochemical demands and the electronic situation of the phenyl substituents of 10, respectively possibly preventing the formation of a co-operative tetrametric system between compounds and DNA bases.
