Biological Activity of Chelidonine

DescriptionChelidonine is a promising model compound for overcoming MDR and for enhancing cytotoxicity of chemotherapeutics, especially against leukaemia cells, its efficacy needs to be confirmed in animal models. Chelidonine may be a potential therapeutic agent against metastasis of invasive human cancer cells, exhibits anti‑migratory and anti‑invasive effects in MDA‑MB‑231 cells, by suppressing COL‑I‑induced integrin signaling, through inhibiting the formation of the IPP complex and subsequent down‑regulation of IPP downstream signaling molecules, such as Akt and ERK1/2.
TargetsAkt | ERK | Bcl-2/Bax | Caspase | p53 | P450 (e.g. CYP17) | ROS | PI3K | JAK | STAT | p38MAPK | P-gp

Multiple mechanisms of cell death induced by chelidonine in MCF-7 breast cancer cell line.[Pubmed: 25265580]

Chem Biol Interact. 2014 Sep 30;223C:141-149.

In a preliminary study screening anti-proliferative natural alkaloids, a very potent benzophenanthridine, Chelidonine showed strong cytotoxicity in cancer cells. While several modes of death have been identified, most of anti-cancer attempts have focused on stimulation of cells to undergo apoptosis.
METHODS AND RESULTS:
Chelidonine seems to trigger multiple mechanisms in MCF-7 breast cancer cells. It induces both apoptosis and autophagy modes of cell death in a dose dependent manner. Alteration of expression levels of bax/bcl2, and dapk1a by increasing concentration of Chelidonine approves switching the death mode from apoptosis induced by very low to autophagy by high concentrations of this compound. On the other hand, submicromolar concentrations of Chelidonine strongly suppressed telomerase at both enzyme activity and hTERT transcriptional level. Long exposure of the cells to 50 nanomolar concentration of Chelidonine considerably accelerated senescence.
CONCLUSIONS:
Altogether, Chelidonine may provide a promising chemistry from nature to treat cancer.

Modulation of multidrug resistance in cancer cells by chelidonine and Chelidonium majus alkaloids.[Pubmed: 23238299]

Phytomedicine. 2013 Feb 15;20(3-4):282-94.

Cancer cells often develop multidrug resistance (MDR) which is a multidimensional problem involving several mechanisms and targets.
METHODS AND RESULTS:
This study demonstrates that Chelidonine and an alkaloid extract from Chelidonium majus, which contains protoberberine and benzo[c]phenanthridine alkaloids, has the ability to overcome MDR of different cancer cell lines through interaction with ABC-transporters, CYP3A4 and GST, by induction of apoptosis, and cytotoxic effects. Chelidonine and the alkaloid extract inhibited P-gp/MDR1 activity in a concentration-dependent manner in Caco-2 and CEM/ADR5000 and reversed their doxorubicin resistance. In addition, Chelidonine and the alkaloid extract inhibited the activity of the drug modifying enzymes CYP3A4 and GST in a dose-dependent manner. The alkaloids induced apoptosis in MDR cells which was accompanied by an activation of caspase-3, -8,-6/9, and phosphatidyl serine (PS) exposure. cDNA arrays were applied to identify differentially expressed genes after treatment with Chelidonine and the alkaloid extract. The expression analysis identified a common set of regulated genes related to apoptosis, cell cycle, and drug metabolism. Treatment of Caco-2 cells with 50 μg/ml alkaloid extract and 50 μM Chelidonine for up to 48 h resulted in a significant decrease in mRNA levels of P-gp/MDR1, MRP1, BCRP, CYP3A4, GST, and hPXR and in a significant increase in caspase-3 and caspase-8 mRNA.
CONCLUSIONS:
Thus, Chelidonine is a promising model compound for overcoming MDR and for enhancing cytotoxicity of chemotherapeutics, especially against leukaemia cells. Its efficacy needs to be confirmed in animal models.

In vivo

Cytotoxicity and apoptotic signalling cascade induced by chelidonine-loaded PLGA nanoparticles in HepG2 cells in vitro and bioavailability of nano-chelidonine in mice in vivo.[Pubmed: 23850776]

Toxicol Lett. 2013 Sep 12;222(1):10-22.

Poor oral bioavailability of Chelidonine, a bio-active ingredient of Chelidonium majus, showing anti-cancer potentials against cancer cells with multidrug resistance, makes its optimal use rather limited.
METHODS AND RESULTS:
To address this problem, we encapsulated Chelidonine in biodegradable poly(lactide-co-glycolide) (PLGA) polymers and evaluated nano-Chelidonine's (NCs) anti-cancer efficacy vis-à-vis free Chelidonine (FC) against HepG2 cells and also evaluated its bioavailability in mice. Physicochemical characteristics indicated that stable spherical NC were formed in nanometer size range (123±1.15 nm) with good yield (86.34±1.91%), better encapsulation efficiency (82.6±0.574%), negative surface charge (-19.6±2.48 mV) and ability of prolonged and sustained release of Chelidonine. Fourier transform infrared analysis revealed that NC resembled similar peaks as that of FC suggesting effective encapsulation in PLGA. NC exhibited rapid cellular uptake and stronger apoptotic effect (∼46.6% reduced IC₅₀ value) than FC, blocking HepG2 cells at G2/M phase. p53, cyclin-D1, Bax, Bcl-2, cytochrome c, Apaf-1, caspase-9 and caspase-3 expressions also corroborated well to suggest greater anticancer potentials of NC.
CONCLUSIONS:
Our in vivo studies demonstrated NC to be more bio-available than FC and showed a better tissue distribution profile without inducing any toxicity (100 mg/kg bw) in mice. Unlike FC, NC could permeate into brain tissue, indicating thereby NC's better potentials for use in therapeutic oncology.

Chelidonine suppresses migration and invasion of MDA-MB-231 cells by inhibiting formation of the integrin-linked kinase/PINCH/α-parvin complex.[Pubmed: 25890994]

Mol Med Rep. 2015 Aug;12(2):2161-8.

Metastasis is the primary cause of cancer-associated mortality. The ternary IPP complex of integrin-linked kinase, PINCH and parvin functions as a signaling platform for integrins, which modulate numerous cellular processes including cell migration and invasion. Chelidonine, isolated from Chelidonium majus, is a benzophenanthridine alkaloid that exhibits anticancer properties; however, the anti‑migratory and anti‑invasive effects of Chelidonine remain unknown.
METHODS AND RESULTS:
The aim of the present study was to investigate the inhibitory effects of Chelidonine on migration and invasion of MDA‑MB‑231 human breast cancer cells, and to determine the underlying mechanisms. Chelidonine was shown to inhibit the migration and invasion of MDA‑MB‑231 cells in a concentration‑dependent manner, without affecting the cell viability. Chelidonine did not significantly inhibit the adhesion of the cells to type 1 collagen (COL‑I), however it did affect cell spreading and reorganization of the actin cytoskeleton. Chelidonine also inhibited COL‑I‑induced protein kinase B (Akt) activation and translocation to the plasma membrane, however, it did not significantly inhibit the activation of focal adhesion kinase. Notably, Chelidonine treatment significantly inhibited COL‑I‑induced formation of the IPP complex and activation of IPP downstream signaling molecules, such as extracellular signal‑regulated kinase (ERK)1/2.
CONCLUSIONS:
These results suggest that Chelidonine exhibits anti‑migratory and anti‑invasive effects in MDA‑MB‑231 cells, by suppressing COL‑I‑induced integrin signaling, through inhibiting the formation of the IPP complex and subsequent down‑regulation of IPP downstream signaling molecules, such as Akt and ERK1/2. These results suggest that Chelidonine may be a potential therapeutic agent against metastasis of invasive human cancer cells.

To evaluate the role of Chelidonine isolated from ethanolic extract of Chelidonium majus in inducing apoptosis in HeLa cells and to assess the main signalling pathways involved.
METHODS AND RESULTS:
Cells were initially treated with different concentrations of Chelidonine for 48 h and the median lethal dose (LD50) value was selected by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Morphological analysis of nuclear condensation and DNA damage and fragmentation were measured by 4',6-diamidino-2-phenylindole staining and comet assay. Further, reactive oxygen species (ROS) generation, cell cycle arrest and change in mitochondrial membrane potential were also examined and analyzed by flow cytometry. Evaluation of interaction of drug with CT DNA was investigated by circular dichroism (CD) spectral analysis to find any possible drug-CT DNA interaction. The mRNA and protein expressions of major signal proteins like p38, p53, protein kinase B (AKT), phosphatidylinositol 3-kinases (PI3K), Janus kinase 3 (JAK3), signal transducer and activator of transcription 3 (STAT3) and E6 and E7 oncoproteins as well as the pro-apoptotic genes and antiapoptotic genes were also estimated by reverse transcriptase-polymerase chain reaction and Western blotting. Based on LD(50) value (30 μg/mL) of Chelidonine, three doses were selected, namely, 22.5 μg/mL (D1), 30.0 μg/mL (D2) and 37.5 μg/mL (D3). Results showed that Chelidonine inhibited proliferation and induced apoptosis in HeLa cells through generation of ROS, cell cycle arrest at sub-G1 and G0/G1 stage, change in mitochondrial membrane potential and fragmentation of DNA. Results of CD spectra showed effective interaction between Chelidonine and calf thymus DNA. Studies of signalling pathway revealed that Chelidonine could efficiently induce apoptosis through up-regulation of expressions of p38, p53 and other pro-apoptotic genes and down-regulation of expressions of AKT, PI3K, JAK3, STAT3, E6, E7 and other antiapoptotic genes.
CONCLUSIONS:
Chelidonine isolated from Chelidonium majus efficiently induced apoptosis in HeLa cells through possible alteration of p38-p53 and AKT/PI3 kinase signalling pathways.
