Benzoylaconine (Benzoylaconitine) is an orally active monoester alkaloid found in the traditional Chinese medicine Aconitum carmichaelii. Benzoylaconine is an ACE2 agonist (EC₅₀: 1.5 μM) with antihypertensive and anti-heart failure effects. Benzoylaconine inhibits TLR-induced MAPK and NF-κB pathways to exert anti-inflammatory effects. Benzoylaconine upregulates the protein levels of P-gp, MRP2, and has anti-tumor effects.

Stock Solution Working Solution

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.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
