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): 41428153. 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 41428153: 'Conjugation of trastuzumab with 3p-C-DEPA-NCS, 3p-C-DEPA-TFP-PEG4, DOTA-NCS, and macropa-NCS yielded immunoconjugates'. Stage set/updated at stage 23 from PMID 41428153: 'Preclinical characterization of 3p-C-DEPA-NCS and 3p-C-DEPA-TFP-PEG4 as potential Actinium-225 bifunctional chelators using DOTA-NCS and macropa-NCS as benchmarks.'.
