Abstract

Two previously undescribed 7, 20-epoxy-ent-kauranes along with six known ent-kauranoids, were isolated from the aerial parts of Isodon eriocalyx. The structures of new compounds were established on the basis of extensive spectroscopic analyses. Compound 2 could inhibit the production of interleukin - 1β (IL - 1β) in monosodium urate (MSU) and lipopolysaccharide (LPS) induced macrophages.

Abstract

Two new eremophilanolides, sibiriolides A (1) and B (2), were isolated from the aerial parts of Xanthium sibiricum. The structures of the new compounds were identified as 4S,5R,7R,8R, 11R-2-oxo-1(10)-eremophilen-12,8-olide (1) and 4S,5R,7R,8R,11S-2-oxo-1(10)-eremophilen-12,8-olide (2) by HREIMS and NMR spectroscopic techniques in combination with X-ray crystallographic analysis and CD measurements.
