Withanolide A (1 μM, 4 days) can induce presynaptic and postsynaptic reconstruction of rat neurons and induce significant regeneration of axons and dendrites[1].
Withanolide A (0.5-2 μM, 24-48 h) inhibits growth of CaOV3 and SKOV3 ovarian cancer cells by targeting Notch1 and Notch3[2].
Withanolide A (0.5-50 μg/mL, 3 h) has the potential of vascular relaxation by promoting the production of NO in endothelial cells[3].

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.
