Target Overlap

ephedra and Piper share 6478 molecular targets based on binding affinity data from BindingDB (Kd/IC50 ≤ 10 µM) and ChEMBL. A Jaccard index of 0.694 means 69% of the combined target set is bound by both compounds. The IDF-weighted score of 0.657 accounts for non-specific binding to metabolic enzymes.

Note: High target overlap does not imply identical mechanism or therapeutic equivalence. Binding affinity, tissue distribution, bioavailability, and downstream signaling differ significantly between compounds even when they bind the same protein.
