We have cross-listed the compounds included in our SCREEN-WELL® kinase inhibitor library (BML-2832) with the compounds included in our SCREEN-WELL® FDA-approved drug library (BML-2843). We have also checked the FDA website and went through the entire list of compounds. As far as we can tell, there is only a single compound that has been approved by the FDA (i.e. Rapamycin, also referred to as Sirolimus).
