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.

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.

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.

A sensitive and selective liquid chromatography-tandem mass spectrometry method for simultaneous determination of five isoquinoline alkaloids from Chelidonium majus L. in rat plasma and its application to a pharmacokinetic study

Chelidonium majus L. is one of the most important medicinal plants of the family Papaveraceae. Its pharmacological effects have been primarily attributed to the presence of a number of alkaloids. In the present study, a sensitive and selective liquid chromatography-tandem mass spectrometry method for simultaneous determination of five isoquinoline alkaloids from Chelidonium majus L. was developed and validated. The analytes (protopine, chelidonine, coptisine, sanguinarine and chelerythrine), together with the internal standard (palmatine), were extracted from acidified rat plasma with ethyl acetate-dichloromethane (4:1, v/v). Chromatographic separation was carried out on a Diamonsil C18 column with an isocratic mobile phase consisting of acetonitrile and water (adjusted to pH 2.3 with formic acid) (30:70, v/v) at a flow rate of 0.4 ml/min. Mass spectrometric detection was performed by selected reaction monitoring mode via electrospray ionization source operating in positive ionization mode. The assay exhibited good linearity (r ? 0.9933) for all the analytes. The lower limits of quantification were 0.197-1.27 ng/ml using only 50 mul of plasma sample. The intra- and inter-day precisions were less than 11.9%, and the accuracy was between -6.3% and 9.3%. The method was successfully applied to the pharmacokinetic study of the five alkaloids in rats after intragastric administration of Chelidonium majus L. extract.

Synergistic effects of Ginseng C. A. Mey and Astragalus membranaceus (Fisch.) Bunge on activating mice splenic lymphocytes detected by microcalorimetry and the underlying mechanisms predicted by in silico network analysis

The aim of the current study was to investigate the combination effect of Ginseng C. A. Mey (ginseng) and Astragalus membranaceus (Fisch.) Bunge (astragalus) which are commonly used for strengthening immune system. In this study, the effects of ginseng, astragalus and their combination on activating mice splenic lymphocytes were studied by microcalorimetry in vitro. The parameters of Pmax, Q and Tmax of heat-production curve in spleen lymphocytes were recorded and analyzed, as well as their association with drug concentration. Through the combination index analysis, it was found that ginseng and astragalus could induce the heat generation of splenic lymphocytes. Network analysis was used to investigate the mechanisms, which showed that their combination may cause immune activation in the body through several signaling pathways such as T cell receptor signaling pathway and PI3?K-Akt signaling pathway.
