Euphane- and 19(10 → 9)abeo-euphane-type triterpenoids from Jatropha gossypiifolia

Four new tetracyclic triterpenoids (1–4) were isolated from the leaves and twigs of Jatropha gossypiifolia. Their structures were elucidated by MS and NMR data analysis, together with the Mo2(OAc)4-induced CD data. Jagabeoeuphols A-C (1–3) are rare 19(10 → 9)abeo-euphane-type triterpenoids possessin...

Summary:Four new tetracyclic triterpenoids (1–4) were isolated from the leaves and twigs of Jatropha gossypiifolia. Their structures were elucidated by MS and NMR data analysis, together with the Mo2(OAc)4-induced CD data. Jagabeoeuphols A-C (1–3) are rare 19(10 → 9)abeo-euphane-type triterpenoids possessing a Δ5(10) group and a 7,8-epoxide moiety, and jagoseuphone A (4) is a typical euphane-type triterpenoid. The inhibitory effects of 1–4 on nitric oxide production induced by lipopolysaccharide in RAW264.7 cells were evaluated, and 4 exhibited moderate inhibitory activity with an IC50 value of 20.1 μM.
