| Manual synthesis | — | none | ≥96% | ≥95% | eSOMA-02 | 37513897 2023 Pharmaceuticals (Basel) [203Pb]PbCl2 (40 MBq) in 0.5 M HCl ... was added to a mixture of DOTAM-TATE or eSOMA-(01-03) (1 nmol), ascorbic acid/gentisic acid (10 μL, 50 mM), sodium acetate (30 μL, 2.5 M), and H2O (final volume of 140 μL). The mixture was incubated for 20 min at rt. — All labeled compounds were obtained with a RCY ≥ 96% and a RCP ≥ 95%. |

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): 37513897. 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 37513897: 'DOTAM-TATE or eSOMA-(01-03)'.
