| Additional Infomation |
Trans-rhaponticin is a rhaponticin in which the double bond adopts a trans-configuration. It possesses a range of pharmacological activities including antitumour, antiinflammatory, antilipemic and neuroprotective activities. It has a role as an anti-inflammatory agent, a plant metabolite, a neuroprotective agent, an EC 2.3.1.85 (fatty acid synthase) inhibitor, an antineoplastic agent, an apoptosis inducer, an angiogenesis inhibitor, a hypoglycemic agent, an anti-allergic agent and an antilipemic drug. Rhapontin has been reported in Rheum likiangense, Rheum franzenbachii, and other organisms with data available. |
Solubility Data
| Solubility (In Vitro) | DMSO: 84~250 mg/mL (199.8~594.7 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (4.95 mM) (saturation unknown) in 10% DMSO + 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 20.8 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL 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: ≥ 2.08 mg/mL (4.95 mM) (saturation unknown) in 10% DMSO + 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 20.8 mg/mL clear DMSO 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. (Please use freshly prepared in vivo formulations for optimal results.) |
