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): 35666363. 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 35666363: 'DO3A-BODIPY-Tz (13)'. Stage set/updated at stage 23 from PMID 35666363: 'Pilot small animal in vivo immuno-SPECT imaging with [111In]In-DO3A-BODIPY-Tz-TCO-trastuzumab was also conducted and exhibited high tumor uptake (21.2 ± 5.6%ID/g 6 days post-injection) with low uptake in non-target tissues.'.
