Biological Activity

Description Tubeimoside I (Lobatoside H, TBMS1), a triterpenoid saponin, isolated from the tubers of Bolbostemma paniculatum, shows potent antitumor and antitumor-promoting effects.
In vitro
In vitro TBMS I inhibits the proliferation of both HepG2 and L-02 cells in a dose- and time-dependent manner, but HepG2 cells appear more sensitive to the agent. When exposed to TBMS I for 24, 48 and 72 h, IC50 for HepG2 cells versus L-02 cells are 15.5 vs. 23.1, 11.7 vs. 16.2, 9.2 vs. 13.1 (μM, p<0.01), respectively. TBMS I induces cell shrinkage, nuclear condensation and fragmentation, cell cycle arrest at the G2/M phase, mitochondrial membrane disruption, release of cytochrome c from the mitochondria, activation of caspase 3 and 9, and shifting Bax/Bcl-2 ratio from being anti-apoptotic to pro-apoptotic, all indicative of initiation and progression of apoptosis involving mitochondrial dysfunction[1].
Cell Research Cell lines HepG2 cells, L-02 cells, HCCLM3 cells, or QSG-7701 cells
Concentrations 5, 10, 15, 20, 30, 40, 90 μM
Incubation Time 24, 48 and 72 h
Method TBMS I cytotoxicity to cultured HepG2 cells, L-02 cells, HCCLM3 cells, or QSG-7701 cells are evaluated in terms of proliferation inhibition determined by the relative absorbance of MTT dye by the cells. In brief, cells (1×104 cells/well) are seeded in 96-well tissue culture plates and then cultured in RPMI-1640 growth medium for 24 h. Subsequently, the medium is replaced with RPMI 1640 growth medium containing designated concentrations of TBMS I (5, 10, 15, 20, 30, 40, 90 μM). Cells treated with sham containing equal volume of cell culture medium but no TBMS I (0 μM) are used as control in every experiment throughout this study. After exposure to TBMS I for 24, 48 and 72 h, MTT dye is added into each well at a final concentration of 0.5 mg/ml, and the plates are incubated for an additional 4 h at 37 °C. The insoluble formazan produced by the living cells in response to MTT dye is collected and dissolved in DMSO and measured with an ELISA reader at the wavelength of 492 nm. Each plate contained multiple wells for a given experimental condition and multiple wells of control. The procedure is replicated three times.
In Vivo
In vivo TBMS1 significantly inhibits the production of the pro-inflammatory cytokines, TNF-α, IL-6 and IL-1β in vitro and in vivo. Pretreatment with TBMS1 markedly attenuates the development of pulmonary edema, histological severities and inflammatory cells infiltration in mice with acute lung injury (ALI). TBMS1 exerts an anti-inflammatory effect in vivo model of ALI through suppression of IkB activation and p38/extracellular signal-regulated kinase mitogen-activated protein kinases signaling in a dose-dependent manner. TBMS1 could be a potent anti-tumor agent by inducing apoptosis in a variety of cancer types via the mitochondrial-related signaling pathway[2].

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
