  Two new glycosidated coumaramides from Clerodendron cyrtophyllum

  摘要：

  Two new glycosidated coumaramides clerodendiod A (1) and B (2), together with seven known glycosidic compounds were isolated from the branches of Clerodendron cyrrophyllum Turcz. Clerodendiod A and B were elucidated as beta-D-glucopyranosyl-(1 -> 3)-beta-D-glucopyranosyl-(1 -> 3)-[6-O-(E)-p-methoxycinnamoyl]-beta-D-glucopyranosyl-(1 -> 2)-[4-O-4((E)-2-(4-acetamidobutylcarbamoyl)vinyl)-phenyl]-alpha-L-rhamnopyranoside (1) and 6-O-(E)-p-coumaroyl-beta-D-glucopyranosyl-(1 -> 3)-beta-D-glucopyranosyl-(1 -> 3)-[6-O-(E)-p-methoxycinnamoyl]-beta-D-glucopyranosyl-(1 -> 2)-[4-O-((E)-2-(4-acetamidobutylcarbamoyl)vinyl)-phenyl]-alpha-L-rhamnopyranoside (2) on the basis of chemical and spectral evidence. The isolated new compound 2 was assayed for the inhibition of the NF-kappa B pathway and showed potent activity in inhibiting NF-kappa B which its IC50 values was found to be 24.9 nM.
