Suberosin Attenuates the Proliferation of MCF-7 Breast Cancer Cells in Combination with Radiotherapy or Hyperthermia
Curr Drug Res Rev 2021;13(2):148-153.PMID:33371865DOI:10.2174/2589977512666201228104528.
Aim: The aim of this study was to determine the proliferation of MCF-7 following irradiation or hyperthermia as alone or pre-treatment with Suberosin. Background: Radiotherapy is a major therapeutic modality for the control of breast cancer. However, hyperthermia can be prescribed for relief of pain or enhancing cancer cell death. Some studies have attempted its use as an adjuvant to improve therapeutic efficiency. Suberosin is a cumarin- derived natural agent that has shown anti-inflammatory properties. Objective: In this in vitro study, possible sensitization effect of Suberosin in combination with radiation or hyperthermia was evaluated. Methods: MCF-7 breast cancer cells were irradiated or received hyperthermia with or without treatment with Suberosin. The incidence of apoptosis as well as viability of MCF-7 cells were observed. Furthermore, the expressions of pro-apoptotic genes such as Bax, Bcl-2, and some caspases were evaluated using real-time PCR. Results: Both radiotherapy or hyperthermia reduced the proliferation of MCF-7 cells. Suberosin amplified the effects of radiotherapy or hyperthermia for induction of pro-apoptotic genes and reducing cell viability. Conclusion: Suberosin has a potent anti-cancer effect when combined with radiotherapy or hyperthermia. It could be a potential candidate for killing breast cancer cells as well as increasing the therapeutic efficiency of radiotherapy or hyperthermia.
Identification of Suberosin metabolites in human liver microsomes by high-performance liquid chromatography combined with high-resolution quadrupole-orbitrap mass spectrometer
J Mass Spectrom 2021 Apr;56(4):e4623.PMID:32734675DOI:10.1002/jms.4623.
Suberosin is a natural prenylated coumarin derivative isolated from Citropsis articulata. It has various pharmacological properties, especially as an anticoagulant, for which it has been used since antiquity. However, its metabolic pathway and metabolites have not yet been studied. Therefore, this study characterizes its metabolic pathway and metabolites in human liver microsomes (HLMs) using high-resolution quadrupole-orbitrap mass spectrometry (HRMS/MS). Eight metabolites (M1-M8) were found, including three monohydroxylated (M1-M3), one hydrated (M4), three dihydroxylated (M5-M7), and one glucuronide conjugate (M8). Furthermore, forms of cytochrome P450 (CYPs) responsible for Suberosin metabolism in HLMs were characterized. CYP1A2 was identified as a major enzyme for the production of M1 and M5 metabolites. The M2, M3, and M7 metabolites were predominantly generated by CYP2B6. M8 was the only phase II metabolite, identified as a glucuronide conjugate from either M1 or M2. This glucuronide conjugate may be the only promising metabolite from phase II metabolism. Phase I metabolism, especially hydroxylation, was found to provide a predominant metabolic pathway of Suberosin in HLMs. Further studies should be conducted to explore the metabolites, examining their efficacy and their toxicity in an in vivo system.
Suberosin Alleviates Sepsis-Induced Lung Injury in A Rat Model of Cecal Ligation and Puncture
J Invest Surg 2023 Dec;36(1):1-9.PMID:36345760DOI:10.1080/08941939.2022.2136802.
Background/aims: Sepsis is one of the major problems encountered in intensive care units, causing organ damage and increasing mortality. Suberosin (SBR) is a type of coumarin with antioxidant and anti-inflammatory activities. The goal of this study is to explore the protective effects of SBR on the lungs in a rat model of sepsis. Methods: Male Wistar rats were utilized in this study. A cecal ligation and puncture (CLP) model was applied to induce sepsis. Rats were separated into six groups with nine animals in each group, including healthy control, SBR, CLP, and CLP + SBR (5, 10, and 20 mg/kg) groups. Superoxide dismutase (SOD), glutathione (GSH) enzyme activities, and malondialdehyde (MDA) level were measured via enzyme-linked immunosorbent assay (ELISA). The messenger RNA (mRNA) expressions of tumor necrosis factor α (TNF-α) and interleukin 1β (IL-1β) were evaluated by real-time polymerase chain reaction (RT-PCR). Histopathological changes in the lungs were investigated with hematoxylin and eosin (H&E). Results: MDA levels and GSH and SOD enzyme activities were negatively affected in the CLP group, but SBR treatment ameliorated these oxidative stress parameters in the SBR1-3 groups (p< 0.05). The mRNA expressions of TNF-α and IL-1β were increased in the CLP group, and SBR treatment decreased those expression levels in a dose-dependent manner (p < 0.05). Organ damage and necrosis were seen in the CLP group and were alleviated in the SBR3 group. Immunohistochemical (IHC) analysis of lung tissues demonstrated decreased TNF-α and IL-1β immunopositivity in the SBR1-3 groups (p< 0.05). Conclusions: SBR ameliorated sepsis-related lung injury in a dose-dependent manner. This compound has significant potential as a future agent in the treatment of sepsis.
Suberosin inhibits proliferation of human peripheral blood mononuclear cells through the modulation of the transcription factors NF-AT and NF-kappaB
Br J Pharmacol 2007 Feb;150(3):298-312.PMID:17179947DOI:10.1038/sj.bjp.0706987.
Background and purpose: Extracts of Plumbago zeylanica containing Suberosin exhibit anti-inflammatory activity. We purified Suberosin from such extracts and studied its effects on a set of key regulatory events in the proliferation of human peripheral blood mononuclear cells (PBMC) stimulated by phytohemagglutinin (PHA). Experimental approach: Proliferation of PBMC in culture was measured by uptake of 3H-thymidine; production of cytokines and cyclins by Western blotting and RT-PCR. Transcription factors NF-AT and NF-kappaB were assayed by immunocytochemistry and EMSA. Key results: Suberosin suppressed PHA-induced PBMC proliferation and arrested cell cycle progression from the G1 transition to the S phase. Suberosin suppressed, in activated PBMC, transcripts of interleukin-2 (IL-2), interferon-gamma (IFN-gamma), and cyclins D3, E, A, and B. DNA binding activity and nuclear translocation of NF-AT and NF-kappaB induced by PHA were blocked by Suberosin. Suberosin decreased the rise in intracellular Ca2+ concentration ([Ca2+]i) in PBMC stimulated with PHA. Suberosin did not affect phosphorylation of p38 and JNK but did reduce activation of ERK in PHA-treated PBMC. Pharmacological inhibitors of NF-kappaB, NF-AT, and ERK decreased expression of mRNA for the cyclins, IL-2, and IFN-gamma and cell proliferation in PBMC activated by PHA. Conclusions and implications: The inhibitory effects of Suberosin on PHA-induced PBMC proliferation, were mediated, at least in part, through reduction of [Ca2+]i, ERK, NF-AT, and NF-kappaB activation, and early gene expression in PBMC including cyclins and cytokines, and arrest of cell cycle progression in the cells. Our observations provide an explanation for the anti-inflammatory activity of P. zeylanica.
Evaluation of the Antimalarial Effect of Ferulago angulata (Schlecht.) Boiss. Extract and Suberosin Epoxide Against Plasmodium berghei in Comparison with Chloroquine Using in-vivo Test
Iran J Pharm Res 2016 Summer;15(3):515-521.PMID:27980587doi
Resistance to most antimalarial drugs has encouraged the development of novel drugs. An alternative source for discovering such drugs is natural products. Some Ferulago species are used in folk medicine for their sedative, tonic and anti-parasitic effects. Besides, coumarins isolated from this genus found to have in vitro anti-leishmanicidal effect. The present study is aimed to evaluate the in-vivo antimalarial activity of Ferulago angulata (Schlecht.) Boiss. extract and Suberosin epoxide, using suarian mice. A rodent malaria parasite, Plasmodium berghei was used to inoculate healthy male Swiss Albino mice of age 6-8 weeks and weight 23-27 g. Hydro-alcoholic extract of F. angulata (20, 100, 300, 600 mg/Kg) and Suberosin epoxide suspension (10, 30, 50, 100 mg/Kg) were administered subcutaneously. Parameters including percentage of parasitemia, suppression of parasitemia and mean survival time were determined using standard test such as peter٬s. Chemo-protective effects were exerted by the crude extract and Suberosin epoxide. Maximum effect was observed with the larger doses of the crude extract and Suberosin epoxide. Suberosin epoxide increased the survival time compared to chloroquine. However, the results of this study indicate that the plant has a promising anti-plasmodial activity against plasmodium berghei. Thus, it could be considered as a potential source of new antimalarial agents. Suberosin epoxide at the dose of 100 mg/Kg possesses relatively significant antimalarial effect. Chemical derivatization of the parent compound or preparation of the modified formulation is required to improve its systemic bioavailability.
