Two Pairs of Enantiomeric Alkaloid Dimers from Macleaya cordata

Two pairs of enantiomeric alkaloid dimers, (¡À)-macleayins A (1) and B (2), representing a novel dimerization pattern of two different types of alkaloids via a C-C sigma-bond, were isolated from the aerial parts of Macleaya cordata. The enantiomeric separation was achieved by chiral chromatography. Their structures and stereochemistry were determined by the analysis of extensive spectroscopic data, electronic circular dichroism calculation, and single-crystal X-ray diffraction data. (-)-Macleayin A exhibits modest cytotoxic activity against HL-60 cell line with the IC50 value of 3.51 muM.

A NIR facile, cell-compatible fluorescent sensor for glutathione based on Michael addition induced cascade spirolactam opening and its application in hepatocellular carcinoma

A NIR fluorescence probe with long emission wavelength at 746 nm and high quantum yield of 0.36 was designed and synthesized to selectively detect GSH over Hcy and Cys in living systems. 2-(1,3,3-Trimethylindolin-2-ylidene)acetaldehyde was attached to rhodamine by Knoevenagel condensation to shift the emission to near infrared region. Then, ethylenediamine was linked to M2 get an important intermediate M3. Finally, target molecule named RhNM was synthesized through combined N-[4-(carbonyl)phenyl] with M3. RhNM shows excellent discrimination in detecting GSH from Hcy/Cys along with an obvious color change. The fluorescence band at 746 nm is rapidly enhanced 106-fold after adding GSH, and the quantum was calculated at 0.36. Titration experiments of GSH showed good linear relationship of intensity vs. GSG concentration, and the detection limit was calculated at 70 nM. The proposed mechanism for identifying GSH based on Michael addition involves reactions of the carbon-carbon double bond and subsequent spirolactam opening. Meanwhile, the probe RhNM can work in a wide range of pH of 4-10. The probe RhNM was used for endogenous and exogenous imaging in HepG2 cells for glutathione. There was an outstanding intracellular red fluorescence occurring upon the addition of GSH incubated with HepG2 cells. It has been successfully applied for the determination of GSH in diluted serum and for bio-imaging of GSH in living cells with low cell toxicity. All results indicated that the probe can be used as an ultra-sensitive, near-infrared fluorescent chemical sensor for selectively detecting GSH in living cell. It has great potential in imaging of live tissues and even, animal imaging.

Modulatory Effect of Chelidonium majus Extract and Its Alkaloids on LPS?Stimulated Cytokine Secretion in Human Neutrophils

Due to certain differences in terms of molecular structure, isoquinoline alkaloids from Chelidonium majus engage in various biological activities. Apart from their well-documented antimicrobial potential, some phenanthridine and protoberberine derivatives as well as C. majus extract present with anti-inflammatory and cytotoxic effects. In this study, the LC?MS/MS method was used to determine alkaloids, phenolic acids, carboxylic acids, and hydroxybenzoic acids. We investigated five individually tested alkaloids (coptisine, berberine, chelidonine, chelerythrine, and sanguinarine) as well as C. majus root extract for their effect on the secretion of IL-1beta, IL-8, and TNF-alpha in human polymorphonuclear leukocytes (neutrophils). Berberine, chelidonine, and chelerythrine significantly decreased the secretion of TNF-alpha in a concentration-dependent manner. Sanguinarine was found to be the most potent inhibitor of IL-1beta secretion. However, the overproduction of IL-8 and TNF-alpha and a high cytotoxicity for these compounds were observed. Coptisine was highly cytotoxic and slightly decreased the secretion of the studied cytokines. The extract (1.25?12.5 mug/mL) increased cytokine secretion in a concentration-dependent manner, but an increase in cytotoxicity was also noted. The alkaloids were active at very low concentrations (0.625?2.5 muM), but their potential cytotoxic effects, except for chelidonine and chelerythrine, should not be ignored.

Corydalis bungeana Turcz. attenuates LPS-induced inflammatory responses via the suppression of NF-kappaB signaling pathway in vitro and in vivo

Ethnopharmacological relevance Corydalis bungeana Turcz. (C. bungeana) is one of traditionally used medicines in China and possesses various biological effects, such as anti-inflammatory, antibacterial activity and inhibition of the immune function of the host. Aim of the study we studied the anti-inflammatory effect and molecular mechanism involved of C. bungeana both in vitro and in vivo model system in which the inflammatory response was induced by LPS treatment. Materials and methods Anti-inflammatory activity of C. bungeana was investigated by LPS-induced RAW 264.7 macrophages and BALB/c mice. The production and expression of pro-inflammatory cytokines were evaluated by Griess reagent, ELISA kits and RT-qPCR, respectively. Phosphorylation status of IkappaBalpha and p65 was illustrated by western blot assay. Results C. bungeana reduced the secretion of NO, TNF-alpha, IL-6 and IL-1beta through inhibiting the protein expression of iNOS, TNF-alpha, IL-6 and IL-1beta in vitro and in vivo. Western blot analysis suggested that C. bungeana supressed NF-kappaB activation via regulating the phosphorylation of IkappaBalpha and p65. Immunohistochemical assay also demostrated the histological inflammatory change in liver tissue. Conclusions The results indicate that C. bungeana supresses the activation of NF-kappaB signaling pathway through inhibiting phosphorylation of IkappaBalpha and p65, which results in good anti-inflammatory effect. In addition, C. bungeana attenuates inflammatory reaction by supressing the expression of various inflammatory cytokines both in vivo and in vitro.

Compounds containing a michael-acceptor, especially maleimide or maleic acid derivatives, directly or indirectly linked to a chromophore and their use in long lasting sunscreen compositions

The present invention relates to compounds which are useful as sunscreens. The compounds persist on the skin for much longer than conventional sunscreens because they comprise a Michael acceptor linked directly or indirectly to a chromophore. The Michael acceptor is capable of undergoing a conjugate addition reaction with thiol groups present in cysteine residues of keratin and thus the compound is chemically bound to the skin and will not be removed by immersion in water.

The UV-light induced photosubstitution of 3,4-dibromo-2,5-dihydro-1H- 2,5-pyrroledione (2) [1] with pyrrole derivatives leads to 3-mono- and 3,4- disubstituted pyrrolediones depending on the starting material. These pyrrole homologues of arcyriarubin A (1) are further processed by nucleophilic substitution of the remaining bromine substituent with pyrrolidine. Cleavage of the protecting group affords the free pyrrole substituents. By UV-light irradiation the azasiline, system (6) is accessible, and its structure was established by X-ray methods. The in vitro antibacterial activity of the pyrrolediones was evaluated, and a strong activity of the compounds 4, 7, 8 and 12 against the methicillin- and ciprofloxacin-resistant bacterium Staphylococcus aureus 134/94 was established.

Influence of vinegar and wine processing on the alkaloid content and composition of the traditional Chinese Medicine Corydalis rhizoma (Yanhusuo)

Corydalis Rhizoma is the dried tuber of Corydalis yanhusuo W.T. Wang which is used in traditional Chinese medicine for pain relief and blood activation. Before being used in the clinics, C. yanhusuo is traditionally processed through dry-frying or frying with vinegar, wine or salt. In this study, eleven alkaloids from Corydalis Rhizoma, namely protopine (1), alpha-allocryptopine (2), tetrahydrocolumbamine (3), coptisine (4), palmatine (5), berberine (6), dehydrocorydaline (7), D,L-tetrahydropalmatine (8), tetrahydroberberine (9), corydaline (10) and tetrahydrocoptisine (11) were simultaneously quantified using a newly developed high performance liquid chromatography-diode array detector (HPLC-DAD) method. The influence of vinegar and wine processing on the content of the main alkaloids of Corydalis Rhizoma was investigated. For this purpose, two common formulations with clinical application, namely the water decoction of Corydalis Rhizoma and its formula Jin Ling Zi San (combination of Corydalis Rhizoma and Toosendan Fructus) were studied. In the two water decoctions, wine and vinegar processing increased the amount of tertiary alkaloids. The differences were more pronounced for Jin Ling Zi San, in which case the content of all tertiary alkaloids (compounds 1, 2, 3, 8, 9, 10, 11) was increased by wine processing.

Synthesis and post-polymerization modification of polynorbornene bearing dibromomaleimide side groups

We demonstrate that polynorbornene containing dibromomaleimide side group is a novel polymer platform for post-polymerization modification. Polymer P0 was obtained through ring-opening metathesis polymerization of monomer 2 by using Grubbs third generation catalyst. Subsequently, P0 was chemically modified with 1-butanethiol and benzyl mercaptan to generate P1 and P2, respectively. In this way, the dibromomaleimide units on polymer side chain were quantitatively converted to dithiolmaleimide moieties. All the polymer samples exhibited good thermal stability and relatively high glass transition temperature. Meanwhile, the effects of substituent and solvent on fluorescent properties of the polymers were elucidated.
