Antiinflammatory constituents of Celastrus orbiculatus inhibit the NF-kappaB activation and NO production

J Nat Prod. 2002 Jan;65(1):89-91. doi: 10.1021/np010428r.

Abstract

Two new sesquiterpene esters, 1beta,8beta-diacetoxyl-6alpha,9alpha-difuroyloxydihydro-beta-agarofuran (1) and 1beta-acetoxyl-2beta,6alpha,9alpha-trifuroyloxydihydro-beta-agarofuran (2), together with four known sesquiterpene esters (3-6), celastrol (7), and celaphanol A (8) were isolated from the roots of Celastrus orbiculatus in a search for inhibitors of NF-kappaB activation and nitric oxide production. Compound 7 was the most active, while compounds 1, 2, 4, and 8 showed moderate inhibition in both NF-kappaB activation and nitric oxide production.
