How this set was arrived at. base set per Ph. Eur. general monograph 0125 (rule); receptor ligand with a saturable target -> molar activity (rule); organic-phase radiosynthesis assumed from isotope/compound class, no synthesis data confirming it -> GC residual solvents (preliminary)

Get in touchNotes
Added from reverse module search (stage 6); 2 article(s) with I-125. | Stage 30 (2026-09-18): Modality was 'Preclinical (I-125)' -- a stage and an isotope, not a modality. Left empty: PMID 31410585 describes [125I]CPCR4.3 as 'a preclinical tool' for in-vitro and biodistribution work and says its clearance 'will certainly restrict its use for in vivo imaging applications using 123I (for SPECT) or 124I (for PET)'; no imaging or therapy use is stated. Stage set to Preclinical. Open question: that paper's compound is CPCR4.3, a structurally related ligand, not pentixafor itself -- check whether this row's name is right. | Stage 30 (2026-09-18): renamed from '[125I]Pentixafor' (agent_id i125-pentixafor). The two articles behind this row (PMID 31410585, 32724470) describe [125I]CPCR4.3, 'a structurally related pentapeptide ligand' to pentixafor, not radioiodinated pentixafor itself; no corpus article names an '[125I]pentixafor'. Target from PMID 31410585 ('targeting of hCXCR4 and mCXCR4'). The spelling 'PENTIXAFOR' was dropped from the alternative names so a pentixafor search no longer lands here.
