In this study, limonin derivatives were used to design new anti-inflammatory compounds with high pharmacological activity and low toxicity. A total of 23 new limonin derivatives were discovered, synthesized, and screened for their anti-inflammatory activity against lipopolysaccharide (LPS)-treated RAW 264.7 cells. Of them, compound f4 was found to be the most active, with a higher efficiency compared with limonin and celecoxib. Subsequently, we studied the mechanism underlying the activity of f4 and found that it inhibited proinflammatory cytokines by blocking the NF-κB/MAPK signaling pathway in LPS-treated RAW 264.7 cells as well as mice. In conclusion, f4 may be a promising anti-inflammatory lead compound.

A series of novel oridonin derivatives bearing various substituents on the 14-OH position were designed and synthesised. Their antitumour activity was evaluated in vitro against three human cancer cell lines (HCT116, BEL7402, and MCF7). Most tested derivatives showed improved anti-proliferative activity compared to the lead compound oridonin and the positive control drug 5-fluorouracil (5-Fu). Among them, compound C7 (IC50 = 0.16 μM) exhibited the most potent anti-proliferative activity against HCT116 cells; it was about 43- and 155-fold more efficacious than that of oridonin (IC50 = 6.84 μM) and 5-Fu (IC50 = 24.80 μM) in HCT116 cancer cells. Interestingly, the IC50 value of compound C7 in L02 normal cells was 23.6-fold higher than that in HCT116 cells; it exhibited better selective anti-proliferative activity and specificity than oridonin and 5-Fu. Furthermore, compound C7 possibly induced cell cycle arrest and apoptosis by regulating the p53-MDM2 signalling pathway. Notably, C7 displayed more significant suppression of tumour growth than oridonin in colon tumour xenograft models where the tumour growth inhibition rate was 85.82%. Therefore, compound C7 could be a potential lead compound for the development of a novel antitumour agent.
