The structure you got from ChemSketch is wrong. The epoxide is incorrectly shown with a forward and backward wedge bond. I checked ChemSketch v.10 and v.11 and both have it with the correct stereochemistry.

Turns out this was an error in PubChem (http://pubchem.ncbi.nlm.nih.gov/summary/summary.cgi?cid=6476007). I have been bitten a few times by assuming that PubChem is the gold standard. I have corrected the structure in the new release of DrugBank, which will be out in a month.
