What is the substance here?

The article prose talks about a ~25 kDa glycoprotein, but many of the drugbox fields instead refer to a spirodioxane–furan small molecule (File:3-(2-Furyl)-2,4-dioxaspiro(5.5)undec-8-ene.png). The linked wikidata:Q7879029 likewise has SMILES/InChI/etc for the small molecule but ontology of a glycoprotein. And the MeSH record from Wikidata says it's 68 kDa. SciFinder says Ulinastatin is CASNo 80449-31-6 and the small molecule is 80499-32-7 (separate records) whereas Pubchem lists both registry numbers in its Ulinastatin record and draws the small-molecule structure for it. Sounds like SciFinder is more reasonably correct, and PubChem and Wiki are in a feedback loop with an unknown starting point? DMacks (talk) 15:12, 28 April 2021 (UTC)[reply]

Checking SciFinder, the protein is 80449-32-7 whereas the small molecule is 80499-32-7. So the cross-contaminated database entries probably began as a simple typo in someone's manual keying. I cleaned up Wikidata, and now things here look self-consistent. DMacks (talk) 05:11, 29 April 2021 (UTC)[reply]
