SAFit2 is a drug which acts as a potent and selective inhibitor of the signalling factor FK506 binding protein 51 (FKBP51), which is involved in the downstream response to glucocorticoid release in the body.[1] Since elevated glucocorticoid levels are a characteristic marker of chronic stress, blocking glucocorticoid signalling pathways using SAFit2 has been shown to counteract many of the associated symptoms such as obesity,[2][3] chronic pain,[4][5] depression and anxiety,[6][7] and addiction.[8][9] While SAFit2 itself is a relatively large molecule and is unlikely to have suitable properties to be developed for medical use, it has demonstrated that inhibition of FKBP51 may be a useful therapeutic approach for alleviating consequences of long-term chronic stress and pain.
