21-Acetoxypregna-1,4,9(11),16-tetraene-3,20-dione is an intermediate of delta 9,11 steroids synthesis, for example, Vamorolone (HY-109017). The delta 9,11 steroids are modifications of glucocorticoids and has anti-inflammatory properties. The delta 9,11 steroids are agents for protection against cell damage (lipid peroxidation) and inhibition of neovascularization.

How to use

In Vitro:

Δ9,11 derivatives are designed and developed to stably incorporate into cell membranes and inhibit lipid peroxidation without glucocorticoid or mineralocorticoid activities, thus avoiding side effects associated with traditional corticosteroids. VBP15 acts as a lead compound due to potent NF-κB inhibition and GR translocation similar to prednisone and dexamethasone, lack of transactivation properties, and good bioavailability.
