CURATION_TODO
OPEN
patricin B shares InChIKey HASLPZZCXDUQET-OTXZUHDPSA-N with patricin A, but the sources name them as different compounds. Which record does this structure belong to?
Both structures come from PubChem CIDs cross-referenced by CARD. Identical structures under different names mean at least one cross-reference is wrong upstream; the seeder cannot tell which, so it flags rather than merges.
