Ugandenial A, a New Drimane-type Sesquiterpenoid from Warburgia ugandensis

One new drimane-type sesquiterpenoid, named ugandenial A (1), was isolated from the ethyl acetate extract of the bark of Warburgia ugandensis (Canellaceae) together with eight known drimane-type sesquiterpenoids: 11α-hydroxycinnamosmolide (2), warburganal (3), polygodial (4), mukaadial (5), dendocar...

Sumario:One new drimane-type sesquiterpenoid, named ugandenial A (1), was isolated from the ethyl acetate extract of the bark of Warburgia ugandensis (Canellaceae) together with eight known drimane-type sesquiterpenoids: 11α-hydroxycinnamosmolide (2), warburganal (3), polygodial (4), mukaadial (5), dendocarbin A (6), 9α-hydroxycinnamolide (7), dendocarbin L (8) and dendocarbin M (9). Their structures were established by detailed spectroscopic analysis. In addition a keto-enol equilibrium was demonstrated for compound 1 through a detailed NMR analysis run in CD(2)Cl(2) at 190 K. Cytotoxicity of the isolated compounds against KB cells was evaluated.
