Evidence & regulatory context
- Mechanism
- ChEMBL compound_search 'cobalt protoporphyrin' returned 0 hits: an EXPLICIT NEGATIVE RESULT, not an omission. ClinicalTrials.gov intervention search 'cobalt protoporphyrin OR heme oxygenase-1 inducer' returned 0 trials, also an explicit zero. CoPP is a metalloporphyrin HO-1 inducer used only as a preclinical tool; no human trial administers it. to_trial=false by search, not by assumption.

Model: Unilateral hindlimb ischaemia produced by 2 h tourniquet application followed by 24 h reperfusion; parallel in vitro hypoxia (5 h, <0.5% O2) and 24 h reoxygenation of muscle-derived stem cells
CoPP given during ischaemia reduced gastrocnemius myocyte damage by 38% (86.4% to 53.2% Evans blue positive fibres, p<0.001) and by 30% when given at reperfusion onset; tibialis anterior damage fell 27% only with dosing at reperfusion onset. Delaying to 1 h after tourniquet release abolished protec…
