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: '3p-C-DEPA-NO2 (1, 2- [(carboxymethyl)] [5-(4-nitrophenyl-1-[4, 7, 10-tris(carboxymethyl) -1, 4, 7, 10- tetraazacyclododecan-1-yl]pentan-2-yl)amino]acetic acid), is a decadentate ligand'. 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.'.
