Strophanthidin
Based on 2 publication(s) in Google Scholar
Strophanthidin is a naturally available cardiac glycoside. Strophanthidin 0.1 and 1 nmol/L increases and 1~100 μmol/L inhibits the Na+/K+-ATPase activities, but Strophanthidin 10 and 100 nmol/L does not affect Na+/K+-ATPase activities in cardiac sarcolemmal. Strophanthidin increases both diastolic and systolic intracellular Ca2+ concentration.

Strophanthidin (0~10 μM; 24 hours; MCF-7, A549, and HepG2 cells) is effective at suppressing the growth of cancer cells and has no toxicity in normal cells[1].
Strophanthidin (0.5 to 500 μM; PBMCs) does not show significant cytotoxicity in PBMCs. Strophanthidin (2 μM; MCF-7 cells) can arrest cell cycle at the G2/M phase[1].
Strophanthidin (MCF-7, A549, and HepG2 cells) is effective at suppressing the growth of cancer cells and has no toxicity in normal cells. Strophanthidin (MCF-7, A549, and HepG2 cells) inhibits the expression of checkpoint and cyclin-dependent kinases in three cancer cells compared to untreated controls. Strophanthidin can modulate the protein localization from the nucleus to the membrane as well as to the cytoplasm. Strophanthidin is a monosaccharide cardiac glycoside with one aglycone portion and without any sugar unit. Strophanthidin induces apoptosis by the attenuation of multiple biochemical signaling pathways and by arresting cell cycle at the G2/M phase through p53-dependent and p53-independent mechanisms[1].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Add each solvent one by one: 10% EtOH 90% Corn Oil
Solubility: ≥ 2.5 mg/mL (6.18 mM); Clear solution
