a friedelane-type triterpenoid isolated from the genus Triperygium, possesses antitumor, anti-inflammatory, and immunosuppressive activities. A total of 42 celastrol derivatives (1a–1t, 2a–2l, and 3a–3j) were synthesized and evaluated for their immunosuppressive activities. Compounds 2a–2e showed immunosuppressive effects, with IC50 values ranging from 25 to 83 nM, and weak cytotoxicity (CC50 > 1 μM)
