Estrone vs Nandrolone
Mechanistic comparison of Estrone and Nandrolone C18 steroid with androgenic and anabolic properties. It is generally prepared from alkyl ethers of ESTRADIOL to resemble TESTOSTERONE but less based on molecular target overlap from BindingDB and ChEMBL binding affinity data.

IDF-Weighted Similarity
Jaccard measures raw target overlap. IDF-weighted downweights promiscuous hub targets (e.g. CYP enzymes) that bind many compounds non-specifically.
Evidence Comparison
Target Overlap
Estrone and Nandrolone share 12 molecular targets based on binding affinity data from BindingDB (Kd/IC50 ≤ 10 µM) and ChEMBL. A Jaccard index of 0.316 means 32% of the combined target set is bound by both compounds. The IDF-weighted score of 0.296 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.
