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)

A series of para‐quinone methide (p QM) moiety and C‐20‐ modified derivatives of celastrol were synthesized and evaluated for their inhibitory effect on the secretion of HBsAg and HBeAg as well as the inhibitory effect against HBV DNA replication. The results suggested that amidation of C‐20 carboxylic group could generate derivatives with good anti‐HBV profile, among them compound 14 showed the best
Nur77, an orphan member of the nuclear receptor superfamily, plays an important role in the regulation of inflammatory processes. Our previous work found that celastrol, a pentacyclic triterpene, bound to Nur77 to inhibit inflammation in a Nur77-dependent manner. Celastrol binding to Nur77 promotes Nur77 translocation from nucleus to cytoplasm, resulting in clearance of inflamed mitochondria and then alleviation of inflammation. Here, we report the design, synthesis, SAR study and biological evaluation of a series of celastrol analogs. A total of 24 celastrol derivatives were made. Compound 3a with a K-d of 0.87 mu M was found to be less toxic than celastrol and could be a hit molecule for further optimization. (C) 2019 Elsevier Masson SAS. All rights reserved.
