The labdane diterpene solidagenone and four semisynthetic derivatives were assessed for effects on the glucocorticoid-mediated signal transduction. Solidagenone and the derivatives proved to be active with IC50 values between 1 and 25 micrograms/mL. All compounds were cytotoxic towards L 1210, BHK and COS 7 cells with IC50 from 10-100 micrograms/mL.

prostaglandin content. Concerning the proliferation assays, a significant stimulating effect was observed for compounds 2, 8, 9 on AGS cells and for 5, 7-9 on MRC-5 fibroblasts. Regarding cytotoxicity, solidagenone showed higher toxicity while compounds 4 and 7 were the less toxic. Our results showed that most of the studied compounds act in vitro as gastroprotectors increasing the cellular GSH content. Additionally

A series of nine derivatives (2–10) were prepared from the diterpene solidagenone (1) and their structures were elucidated by means of spectroscopic studies. Their ability to inhibit inflammatory responses elicited in peritoneal macrophages by TLR ligands was investigated. Compounds 5 and 6 showed significant anti-inflammatory effects, as they inhibited the protein expression of nitric oxide synthase
