Notes

Added at stage 22: promoted from 'Reported once' (single-article, no diagnostic pair at discovery) because a full-text synthesis with extracted data exists in parsed-therapy.xlsx -- PMID(s): 40833585. Target/mechanism, clinical application, indications, approval and precursor fields still need per-agent research and are intentionally left empty. Compound class inferred from precursor name (not stated outright) -- PMID 40833585: 'p-SCN-Bn-DOTA-A1-His'. Stage set/updated at stage 23 from PMID 40833585: 'Biodistribution and imaging studies in mice bearing mesothelin-expressing tumors showed specific tumor targeting for both tracers.'.
