| Description: |
Matrine, a novel autophagy inhibitor, possesses anti-inflammation, immunosuppression, anti-fibrotic and anticancer activities, it could inhibit cell proliferation and induce apoptosis of SGC-7901 cells in vitro by up-regulating Fas/FasL expression and activating caspase-3 enzyme. Matrine can be a potential candidate to fight against Candida-related infections by regulating yeast-to-hypha transition.

| J Appl Microbiol. 2014 Sep;117(3):618-26. | | Matrine reduces yeast-to-hypha transition and resistance of a fluconazole-resistant strain of Candida albicans.[Pubmed: 24860982] | To evaluate the potential effect of Matrine on reducing the growth of hypha and lowering the resistance of a fluconazole-resistant colony of Candida albicans.
METHODS AND RESULTS:
Candida albicans SC5314 and a fluconazole-resistant C. albicans 215 were used. As for C. albicans SC5314, minimal inhibitory concentration (MIC(80)) and effective concentration (EC(50)) were determined, 1 mg ml(-1) Matrine could inhibit nearly 80% of planktonic growth by inverted microscope, 2 mg ml(-1) Matrine suppressed 50% of metabolic activity of biofilm by XTT assay, vanishing hypha could be observed on spider agar containing 2 mg ml(-1) Matrine, the expressions of three hypha-related genes, namely ALS 3, SUN 41 and PBS 2, were suppressed by 29, 45 and 61% by 2 mg ml(-1) Matrine. Also, Matrine could lower the resistance of C. albicans 215, in either the free-floating form or the biofilm phenotype.
CONCLUSIONS:
Matrine had favourable antifungal potential and might be able to reverse the fluconazole resistance of clinical isolates at relatively high concentration. The anti-candidal performance of Matrine could be tightly associated with yeast-to-hypha transition proved by spider agar test and qRT-PCR. More efforts are needed to find new antifungal agents. Matrine could be a potential candidate to fight against Candida-related infections by regulating yeast-to-hypha transition. | | Oncol Rep. 2015 May;33(5):2561-6. | | Matrine induces mitochondrial apoptosis in cisplatin-resistant non-small cell lung cancer cells via suppression of β-catenin/survivin signaling.[Pubmed: 25760455] | Matrine is an alkaloid isolated from Sophora flavescens and shows anticancer activities. The present study was carried out to determine the cytotoxic effects of matrine on cisplatin-resistant non-small cell lung cancer (NSCLC) cells and the associated molecular mechanisms.
METHODS AND RESULTS:
Parental and cisplatin-resistant A549 and H460 NSCLC cells were treated with 1 or 2 g/l of matrine for 48 h, and cell viability and apoptosis were assessed. β-catenin-mediated transcriptional activity, mitochondrial membrane potential (ΔΨm) changes, activation of caspases, and survivin expression were examined. The effect of overexpression of survivin on the anticancer activity of matrine was investigated. Compared to the parental cells, cisplatin-resistant NSCLC cells showed increased β-catenin transcriptional activity. Matrine treatment resulted in a significant reduction in β-catenin activation and survivin expression in the cisplatin-resistant cells. Matrine caused apoptotic death in the cisplatin-resistant NSCLC cells, coupled with loss of ΔΨm and activation of caspase-9 and -3. Matrine-induced apoptosis of the cisplatin-resistant NSCLC cells was significantly reversed by overexpression of survivin.
CONCLUSIONS:
In conclusion, matrine exposure induces mitochondrial apoptosis in cisplatin-resistant NSCLC cells, which is largely mediated through inactivation of β-catenin/survivin signaling. Further investigation of the therapeutic benefit of matrine in overcoming cisplatin resistance in NSCLC is warranted. | | Chem Biol Interact. 2009 Sep 14;181(1):15-9. | | Hepatoprotective and anti-hepatocarcinogenic effects of glycyrrhizin and matrine.[Pubmed: 19426721] | Matrine (Mat), a component extracted from Sophora flavescens Ait, has a wide spectrum of pharmacological effects. Glycyrrhizin (Gly), a major active constituent of licorice (Glycyrrhiza glabra) root, has various pharmacological effects. Gly and Mat are ancillary drugs used clinically in China for protection of liver function and treatment of tumors. However, habitual administration of Gly may cause adverse effects marked by the development of pseudohypercorticosteroidism.
METHODS AND RESULTS:
This work was designed to see whether combination use of Gly and Mat could offer better liver protective and anti-hepatocarcinogenic effects than Gly or Mat alone, and whether it could reduce the adverse effects of Gly alone by acetaminophen-induced hepatotoxicity, diethylnitrosamine-induced hepatocarcinogenesis, induction of immunosuppression, albumen-induced swelling of rat hind paws. The results showed that compared with Gly or Mat alone, Gly+Mat reduced the mortality of acetaminophen overdosed mice more effectively, attenuate acetaminophen-induced hepatotoxicity, and reduced the number and area of gamma-GT positive foci, thus protecting liver function and preventing HCC from occurring. In addition, Gly+Mat had a protective effect on immunosuppression, a strong non-specific anti-inflammatory effect, and an effect of reducing the incidence of sodium and water retention. | | Biofactors. 2008;33(2):121-8. | | Matrine inhibits PMA-induced MMP-1 expression in human dermal fibroblasts.[Pubmed: 19346587] | Matrix metalloproteinase-1 (MMP-1) plays an important role in the maintenance and turnover of extracellular matrix (ECM) macromolecules. Remodelling of extracellular matrix by MMPs is a hallmark feature of physiological and pathological processes. In this study, in order to establish the therapeutic potential of Matrine, we investigated its effect on MMP-1 expression in human dermal fibroblast cells.
METHODS AND RESULTS:
We found that Matrine inhibited both MMP-1 mRNA and protein expression induced by PMA (phorbol myristate acetate). Therefore, we characterized the inhibitory mechanism of Matrine on PMA-induced MMP-1 expression. Matrine inhibited PMA-induced activation of the AP-1 promoter, an important nuclear transcription factor in MMP-1 expression. Additionally, we detected that Matrine suppressed the PMA-induced phosphorylation of two mitogen-activated protein kinases, extracellular signal-regulated protein kinase and c-Jun N-terminal kinase, but did not suppress the PMA-induced phosphorylation of p38 kinase.
CONCLUSIONS:
These results suggest that Matrine suppresses PMA-induced MMP-1 expression through inhibition of the AP-1 signaling pathway and also may be beneficial for treatment of some inflammatory skin disorders. |
