Lung cancer is a neoplasm with a 5-year survival rate of less than 15 % and a leading cause of death worldwide, despite recent progress in treatment and diagnostic methods. Lung cancer stem-like cells (CSCs) are pivotal in lung cancer metastasis and drug resistance. This study aimed to develop lung CSCs that stably express stem cell properties through transfection to further screen traditional Chinese herbal compounds. Lung adenocarcinoma stem cells, which include various phenotypic subgroups, are normally characterized by high expression levels of pluripotent stem cell genes, particularly Nanog and OCT4...

Intestinal ischemia-reperfusion (I/R) causes severe destruction in remote organs. Lung damage is a frequently seen complication after intestinal I/R. Ukrain (NSC 631570) is a synthetic thiophosphate derivative of alkaloids from the extract of the celandine (Chelidonium majus L.) plant. We investigated the effect of Ukrain in animals with lung injury induced by intestinal I/R. Adult male Spraque-Dawley rats were randomly divided into four groups: control, Ukrain, I/R, I/R with Ukrain. Before intestinal I/R was induced, Ukrain was administered intraperitoneally at a dose of 7...

The greater celandine (Chelidonium majus L.) has been known for the centuries as a medicinal plant. One of the therapeutic agents based on C. majus is anticancer drug Ukrain™ known as a semi-synthetic C. majus alkaloid derivative. Although there are no doubts about antitumor properties of the drug, there is still controversy about its composition. In this study, Ukrain™ was subjected to TLC and LC-MS/MS analyses to compare it with C. majus alkaloid root extract and to determine its composition. Moreover, microbiological activity of both Ukrain™ and the alkaloid extract were tested against Bacillus subtilis strains using TLC-direct bioautography...

BACKGROUND: Malaria caused by Plasmodium falciparum is the most virulent form of malaria, leading to approximately a half million deaths per year. Chemotherapy continues to be a key approach in malaria prevention and treatment. Due to widespread parasite drug resistance, identification and development of new anti-malarial compounds remains an important task of malarial parasitology. The semi-synthetic drug amitozyn, obtained through alkylation of major celandine (Chelidonium majus) alkaloids with N,N'N'-triethylenethiophosphoramide (ThioTEPA), is a widely used Eastern European folk medicine for the treatment of various tumours...

Lesser celandine, also known as Ranunculus ficaria, is a herbaceous perennial plant that commonly utilizes piles and is taken either internally or used externally. The causality assessment of several reports provided evidence for the existence of Greater Celandine hepatotoxicity. However, there hasn't been any case report published thus far, about lesser celandine induced liver injury. Here, we present a case of 36-year-old woman admitted to the hospital with acute hepatitis and jaundice on her sclera with no history of drug abuse or alcohol consumption...

The genuine major benzylisoquinoline alkaloid occurring in the traditional medicinal plant greater celandine (Chelidonium majus L.) is 13,14-dihydrocoptisine and not - as described previously - coptisine. Structure of 13,14-dihydrocoptisine was elucidated. The discrepancy between the alkaloid pattern of the living plants and that of detached and dried leaves is due to the rapid and prompt conversion of 13,14-dihydrocoptisine to coptisine in the course of tissue injuries. Indeed, apart from the major alkaloid, some minor alkaloids might also be converted; this however is not in the centre of focus of this paper...

This study evaluates the possible protective potentials of chelidonine and its poly lactide-co-glycolide (PLGA) encapsulated nano-form against cadmium chloride (CdCl₂) induced oxidative stress and hepatotoxicity in mice, ex vivo and in vivo. Acute exposure to CdCl₂ (1.0 mg/kg b.w; i.p., twice a week for 30 days) generated oxidative stress in mice through accumulation of reactive oxygen species and increased lipid peroxidation, and levels of certain liver marker enzymes (ALT, AST, ALP) with decrease in levels of GSH and certain other antioxidant enzymes (SOD, CAT, GR) in liver...

Amitozyn (Am) is a semi-synthetic drug produced by the alkylation of major celandine (Chelidonium majus L.) alkaloids with the organophosphorous compound N,N'N'-triethylenethiophosphoramide (ThioTEPA). We show here that the treatment of living cells with Am reversibly perturbs the microtubule cytoskeleton, provoking a dose-dependent cell arrest in the M phase. Am changed the dynamics of tubulin polymerization in vitro, promoted the appearance of aberrant mitotic phenotypes in HeLa cells and induced apoptosis by the activation of caspase-9, caspase-3 and PARP, without inducing DNA breaks...

In this study, the synergistic biological action of five celandine alkaloids in normal and cancer cells was investigated by capillary electrophoresis with light-emitting diode-induced native fluorescence detection. The specific capacity of each alkaloid to penetrate into the cells was estimated by monitoring alkaloid concentration decreases in the cell medium during incubation with murine fibroblast NIH/3T3, mouse melanoma B16F10, and human breast cancer MCF7 cell lines. Mixtures of isoquinoline alkaloids containing protopine, chelidonine, sanguinarine, allocryptopine, and stylopine were applied to cell cultures for 20 and 40 min, and the content of alkaloids in the cell media was measured by capillary electrophoresis (CE)...

Herbal hepatotoxicity is a rare and poorly described disease because reported cases are mostly scattered and lack an appropriate causality assessment. We now describe in detail the clinical picture of herbal hepatotoxicity by extracts of Greater Celandine (GC), syn. Chelidonium majus L. from the Papaveraceae family, which contain more than 20 ingredients including various biologically active isoquinoline alkaloids. For this purpose, we analyzed and reviewed published cases of 16 patients from various European countries...
