Title Rearranged ent-kauranes from the stems of Tricalysia dubia and their biological activities.
Journal J Nat Med
Abstract From the EtOAc-soluble fraction of an MeOH extract of the stems of Tricalysia dubia, two new rearranged ent-kaurane derivatives, named tricalysiolides H and I, were isolated, together with five known rearranged ent-kauranes, i.e. tricalysiolides A-E, stigmast-4-en-6beta-ol-3-one, (+)-pinoresinol, scopoletin and syringaldehyde. Their structures were elucidated from spectroscopic evidence, and their cytotoxicity toward KB cells and P-gp inhibitory activity were assayed.
