MESH:C053590 (quinquefolan B) is combined with CHEBI:16335 (adenosine)

Confirmed on NodeNorm Dev.

The connections here appear to be:

concords/mesh_cas:MESH:C053590	xref	CAS:109767-06-8
concords/PUBCHEM_CAS:PUBCHEM.COMPOUND:60961	xref	CAS:109767-06-8
concords/CHEBI:CHEBI:16335	xref	PUBCHEM.COMPOUND:60961

concords/PUBCHEM_CAS is generated from the "Depositor Supplied Synonyms" of PUBCHEM.COMPOUND:60961 "Adenosine", so that's where that connection comes from.

However, note that CAS:109767-06-8 "quinquefolan B" has "Adenosine" as the chemical name, has exactly the same chemical formula as PUBCHEM.COMPOUND:60961 "Adenosine", but has a slightly different IUPAC name:

ID	IUPAC name
PUBCHEM.COMPOUND:60961	(2R,3R,4S,5R)-2-(6-aminopurin-9-yl)-5-(hydroxymethyl)oxolane-3,4-diol
CAS:109767-06-8	(2R,3R,4S,5R)-2-(6-amino-9H-purin-9-yl)-5-(hydroxymethyl)tetrahydrofuran-3,4-diol

So I think we'll need a chemist to figure out if this needs to be split (and -- if so -- it'll be easier to complain to PubChem about it rather than trying to fix it within Babel.)

"quinquefolan B" seems to be the name of a Polysaccharide glycans extracted from American ginseng though...

Looking up this name from Duckduckgo:
