Antiplasmodial agents from the Bhutanese medicinal plant Corydalis calliantha

The alkaloidal components of the Bhutanese medicinal plant Corydalis calliantha Long, which is used for the treatment of malaria, have been assessed. Four known alkaloids, protopine (1), scoulerine (2), cheilanthifoline (3) and stylopine (4) are reported from this plant for the fi rst time. The protopine alkaloid, protopine, and the tetrahydroprotoberine alkaloid, cheilanthifoline, showed promising in vitro antiplasmodial activities against Plasmodium falciparum, both wild type (TM4) and multidrug resistant (K1) strains with IC50 values in the range of 2.78-4.29 muM. Such activity had not been demonstrated previously for cheilanthifoline. The results thus support, at a molecular level, the clinical use of this plant in the Bhutanese traditional medicine and identifi ed cheilanthifoline as a potential new antimalarial drug lead.

Divergent oriented synthesis for the design of reagents for protein conjugation

Instead of using diversity oriented syntheses (DOS) to obtain compounds with biological activities, we employed the DOS method to efficiently obtain multifunctional single attachment point (MSAP) reagents for the conjugation to proteins. Acid insensitive functional groups (chelators, fluorochromes) were attached to Lys-Cys-NH2 or Lys-Lys-betaAla-Cys-NH2 peptide scaffolds. After cleavage from solid supports, the modified peptide intermediates were split and further modified by two solution phase, chemoselective reactions employing the single amine and single thiol presented on the intermediates. MSAP-based fluorochrome-chelates were obtained, some possessing a third functional group like a polyethylene glycol (PEG) polymer or “click chemistry” reactive alkynes and azides. The DOS of MSAP reagents permitted the efficient generation of panels of MSAP reagents that can be used to obtain multifunctional proteins with a single modified amino acid (a single attachment point).

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.

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.

ELICITOR INDUCTION AND CHARACTERIZATION OF MICROSOMAL PROTOPINE-6-HYDROXYLASE, THE CENTRAL ENZYME IN BENZOPHENANTHRIDINE ALKALOID BIOSYNTHESIS

The chemical synthesis of <6-3H>protopine is described.Microsomal preparations from Eschscholtzia california cell suspension cultures challenged with a crude elicitor preparation from yeast, catalyse the hydroxylation of <6-3H>protopine with the concomitant formation of <11-3H>dihydrosanguinarine and HO3H.This reaction served as an assay for the enzyme.The hydroxylase reaction is strictly dependent on NADPH as a reducing cofactor and on molecular oxygen.Cytochrome c, inhibitors such as prochloraz and ketoconazole and carbon monoxide inhibit the hydroxylation reaction, suggesting that the enzyme is a cytochrome P-450 linked monooxygenase.The hydroxylase was induced by the yeast elicitor ca eight-fold, 20h after challenging the plant cell culture with the yeast carbohydrate, having no effect on the cell dry weight of the culture.The hydroxylase is specifically present in different plant species that produce benzophenanthridine alkaloids in culture and also respond to induction by the elicitor.

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.

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.
