Sixteen new and three known polyacylated ent-kaurane diterpenoid glycosides were isolated from Inula hupehensis, with compound 5 showing notable inhibition of nitric oxide production. Additionally, compound 13 displayed strong inhibitory effects in an alpha-glucosidase assay.
Sixteen new (1-16) and three known (17-19) polyacylated ent-kaurane diterpenoid glycosides were isolated from the aerial parts of Inula hupehensis. The planar structures of 1-16 and their relative configurations were established on the basis of extensive spectroscopic analysis. The absolute configurations of all stereogenic centers for compounds 1 and 6 were determined by single-crystal X-ray diffraction experiments, and the absolute configurations of the other new compounds were assigned by chemical degradation and experimental ECD data. Antineuroinflammatory testing of all the isolates showed that compound 5 inhibited lipopolysaccharide-induced nitric oxide production in BV-2 microglial cells with an IC50 value of 15.6 mu M. In an alpha-glucosidase inhibitory assay, compound 13 exhibited a strong inhibitory effect with an IC50 value of 32.8 mu M, whereas the IC50 value of the positive control, acarbose, was 387.8 mu M.
