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): 42569132. 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 42569132: 'Compound PEG2-COU (m = 2): obtained as a faint yellow solid in 20.3% yield.'. | Stage 30 (2026-09-18): Modality was 'Therapy' -- a bucket value given to every agent found by the therapy-oriented bulk search (stages 21-22), not a source statement. Corrected to PET: Ga-68 is a positron emitter used only for PET imaging. Linked articles: PMID 42569132.
