| In vitro | Sennoside B inhibits PDGF receptor signaling and cell proliferation induced by PDGF-BB in human osteosarcoma cells.[Pubmed: 19393247]Life Sci. 2009 Jun 19;84(25-26):915-22.AIMS:
To address the possibility that Sennoside B inhibition of cell proliferation is mediated via interference with platelet-derived growth factor (PDGF) signaling.
MAIN METHODS:
Human osteosarcoma MG63 cells were treated with PDGF in the presence or absence of Sennoside B. Activation of the PDGF signaling pathway was monitored using western immunoblotting with specific antibodies against the PDGF receptor, phosphotyrosine and components of the downstream signaling cascade. Activation of cell metabolism and proliferation was assessed by chromogenic reduction of MTT.
KEY FINDINGS:
Sennoside B was found to inhibit PDGF-BB-induced phosphorylation of the PDGF receptor (PDGFR) in human MG63 osteosarcoma cells. Downstream signaling was also affected; pre-incubation of PDGF-BB with Sennoside B inhibited the phosphorylation of pathway components including Ak strain To address the possibility that Sennoside B inhibition of cell proliferation is mediated via interference with platelet-derived growth factor (PDGF) signaling.

Production of monoclonal antibodies against a major purgative component, sennoside B, their characterization and use in ELISA.[Pubmed:11534608]
Analyst. 2001 Aug;126(8):1372-6.
For immunization, Sennoside B was conjugated with bovine serum albumin. The hapten density in the antigen conjugate was determined to be 3 mol mol(-1) protein by matrix-assisted laser desorption-ionization TOF mass spectrometry. A hybridoma secreting monoclonal antibody against Sennoside B was produced by fusing splenocytes from mouse immunized with the Sennoside B conjugate and mouse myeloma cells. Weak cross-reactivities occurred with sennoside A which is a stereochemical isomer, and a monomer of Sennoside B, rhein, but no cross-reactivity was observed with other related anthraquinones and phenolics. The range of the assay extended from 0.5 ng ml(-1) to 15 ng ml(-1) of Sennoside B, and good correlation between ELISA and HPLC methods was obtained when crude extracts of rhubarb were analyzed.
Experimental evaluation of radioiodinated sennoside B as a necrosis-avid tracer agent.[Pubmed:25330022]
J Drug Target. 2015 Feb;23(2):180-90.
Necrosis-avid agents are a class of compounds that selectively accumulate in the necrotic tissues after systemic administration, which can be used for in vivo necrosis imaging and targeted therapies. In order to search for a necrosis-avid tracer agent with improved drugability, we labelled iodine-131 on Sennoside B (SB) as a naturally occurring median dianthrone compound. The necrosis targetability and clearance properties of (131)I-SB were evaluated in model rats with liver and muscle necrosis. On SPECT/CT images, a "hot spot" in the infarcted liver lobe and necrotic muscle was persistently observed at 24 h and 72 h post-injection (p.i.). Gamma counting of the tissues of interest revealed a radioactivity ratio of necrotic to viable liver at 4.6 and 3.4 and of necrotic to viable muscle at 7.0 and 8.8 at 24 h and 72 h p.i., respectively. The good match of autoradiographs and fluoromicroscopic images with corresponding histochemical staining suggested preferential uptake of (131)I-SB in necrotic tissue. Pharmacokinetic study revealed that (131)I-SB has an elimination half-life of 8.6 h. This study indicates that (131)I-SB shows not only prominent necrosis avidity but also favourable pharmacokinetics, which may serve as a potential necrosis-avid diagnostic agent for assessment of tissue viability.
Sennoside B inhibits PDGF receptor signaling and cell proliferation induced by PDGF-BB in human osteosarcoma cells.[Pubmed:19393247]
Life Sci. 2009 Jun 19;84(25-26):915-22.
AIMS: To address the possibility that Sennoside B inhibition of cell proliferation is mediated via interference with platelet-derived growth factor (PDGF) signaling. MAIN METHODS: Human osteosarcoma MG63 cells were treated with PDGF in the presence or absence of Sennoside B. Activation of the PDGF signaling pathway was monitored using western immunoblotting with specific antibodies against the PDGF receptor, phosphotyrosine and components of the downstream signaling cascade. Activation of cell metabolism and proliferation was assessed by chromogenic reduction of MTT. KEY FINDINGS: Sennoside B was found to inhibit PDGF-BB-induced phosphorylation of the PDGF receptor (PDGFR) in human MG63 osteosarcoma cells. Downstream signaling was also affected; pre-incubation of PDGF-BB with Sennoside B inhibited the phosphorylation of pathway components including Ak strain transforming protein (AKT), signal transducer and activator of transcription 5 (STAT-5) and extracellular signal-regulated kinase 1/2 (ERK1/2). Further, we found that Sennoside B can bind directly to the extracellular domains of both PDGF-BB and the PDGF-beta receptor (PDGFR-beta). The effect was specific for Sennoside B; other similar compounds including aloe-emodin, rhein and the meso isomer (sennoside A) failed to inhibit PDGFR activation or downstream signaling. Sennoside B also inhibited PDGF-BB stimulation of MG63 cell proliferation. SIGNIFICANCE: These results indicate that Sennoside B can inhibit PDGF-stimulated cell proliferation by binding to PDGF-BB and its receptor and by down-regulating the PDGFR-beta signaling pathway. Sennoside B is therefore of potential utility in the treatment of proliferative diseases in which PDGF signaling plays a central role.
[Determination of sennoside A and sennoside B simultaneously in health food by HPLC].[Pubmed:21695913]
Wei Sheng Yan Jiu. 2011 May;40(3):355-7.
OBJECTIVE: To develop an analytical method for determination of sennoside A and Sennoside B simultaneously in health food by high performance liquid chromatography (HPLC). METHODS: Samples were extracted by ultrasound extraction and determined by HPLC with a UV detector. Using a Synergi Hydro-RP (250 mm x 4.6 mm, 4 microm) column and a mixture of CH3CN: 1.0% CH3COOH (17:83) as mobile phase for separation. The detection wavelength was at 270 nm. The contents were calculated with an external standard. RESULTS: The linearity was good in the ranges of 1.40 - 28.0 microg/ml for sennoside A and 1.45 - 29.0 microg/ml for Sennoside B. The average recovery rates of sennoside A and Sennoside B were 85.2% -97.2% and 86.1% -96.2%. The RSD was 7.5% and 6.8%, the limit of detection was 0.8 mg/kg and 0. 6 mg/kg, and the limit df quantification was 2.1 mg/kg and 2.0 mg/kg for sennoside A and Sennoside B respectively. CONCLUSION: The method is simple, accurate and suitable for the determination of sennoside A and Sennoside B in health food.
Gastroprotective Activities of Sennoside A and Sennoside B via the Up-Regulation of Prostaglandin E2 and the Inhibition of H(+)/K(+)-ATPase.[Pubmed:26336586]
Biomol Ther (Seoul). 2015 Sep;23(5):458-64.
Sennoside A (erythro) and Sennoside B (threo) are dianthrone glycosides and diastereomers. We investigated their abilities to prevent the gastric lesions associated with diseases, such as, gastritis and gastric ulcer. To elucidate their gastroprotective effects, the inhibitions of HCl*EtOH-induced gastritis and indomethacin-induced gastric ulcers were assessed in rats. It was observed that both sennoside A and Sennoside B increased prostaglandin E2 (PGE2) levels and inhibited H(+)/K(+)-ATPase (proton pump). In a rat model, both compounds reduced gastric juice, total acidity and increased pH, indicating that proton pump inhibition reduces gastric acid secretion. Furthermore, sennoside A and B increased PGE2 in a concentration-dependent manner. In a gastric emptying and intestinal transporting rate experiment, both sennoside A and Sennoside B accelerated motility. Our results thus suggest that sennoside A and Sennoside B possess significant gastroprotective activities and they might be useful for the treatment of gastric disease.
