Cyclovirobuxine D (also known as CVB-D or Bebuxine) is a naturally occurring and bioactive substance that was isolated from the Buxus microphylla and has been used to treat acute myocardial ischemia. The human breast cancer cell line MCF-7 may be induced to undergo autophagy by the alkaloid cyclovirobuxine D, which is found in a traditional Chinese herb. In rats with experimental myocardial injury brought on by sympathetic overactivity, it has a preventing effect against oxidative stress and energy metabolism. Additionally, Cyclovirobuxine D helps treat heart failure brought on by myocardial infarction, which supports its potential as a new treatment for heart failure.
ln Vitro |
Only 10% of MGC-803 cells and 20% of MKN28 cells survived 72 hours after treatment with cyclobuxine D (0-240 µM; 24-72 hours) due to a concentration- and time-dependent decrease in cell viability following CVB-D therapy[2]. Gastric cancer cells' cell cycle is stopped in the S phase in a concentration-dependent manner by cyclobuxine D (0-120 µM; 48 hours) [2]. Cyclovirobuxine D (0-120 µM; 48 hours) induces concentration-dependent apoptosis in gastric cancer cells, particularly early apoptosis. In gastric cancer cells, cyclobuxine D (0-120 µM; 48 hours) induces apoptosis via upregulating cleaved Caspase-3, Bax/Bcl-2 ratio, and other apoptosis-related proteins [2].

Solubility in Formulation 1: ≥ 1.08 mg/mL (2.68 mM) (saturation unknown) in 10% EtOH + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 10.8 mg/mL clear EtOH stock solution to 400 μL of PEG300 and mix evenly; then add 50 μL of Tween-80 to the above solution and mix evenly; then add 450 μL of normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 1.08 mg/mL (2.68 mM) (saturation unknown) in 10% EtOH + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 10.8 mg/mL clear EtOH stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
