| 1. | Bufalin, ouabain and digoxin are a few toxic cardiac glycosides.
|
| 2. | The glycosylation of ouabagenin to add the rhamnose moiety produced ouabain.
|
| 3. | The figure below shows the key steps in the synthesis of ouabain.
|
| 4. | E contained all the required functionalities and stereochemistry needed to produce ouabain.
|
| 5. | Post asked whether the enzyme was inhibited by ouabain.
|
| 6. | Small doses of ouabain can be used to treat hypotension and cardiac arrhythmias.
|
| 7. | There is disagreement though on whether or not this endogenous substance actually is ouabain.
|
| 8. | The total synthesis of ouabain was achieved in 2008 by Deslongchamps laboratory in Canada.
|
| 9. | The structure of E was confirmed by comparison against the degradation product of ouabain.
|
| 10. | Ataxia is observed for lower ouabain concentrations, dystonia is observed at higher ouabain concentrations.
