23,24-Anhydro tacrolimus

CAS: 104987-16-8

23,24-Anhydro tacrolimus is a synthetic prodrug of the immunosuppressant drug tacrolimus. It has the same pharmacological effects as the parent compound and can be used in its place to avoid adverse reactions. The metabolite of 23,24-anhydro tacrolimus is a natural metabolite of tacrolimus and has been synthesized for research purposes or for use as an analytical standard. 23,24-Anhydro tacrolimus is not an impurity standard, but rather a niche product that is not commercially available from suppliers.
