Lysergic vs Nicergoline
Mechanistic comparison of Lysergic Acid Diethylamide Semisynthetic derivative of ergot (Claviceps purpurea). It has complex effects on serotonergic systems including antagonism at some peripheral serotonin receptors and Nicergoline 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.

Target Overlap
Lysergic and Nicergoline share 15 molecular targets based on binding affinity data from BindingDB (Kd/IC50 ≤ 10 µM) and ChEMBL. A Jaccard index of 0.306 means 31% of the combined target set is bound by both compounds. The IDF-weighted score of 0.252 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.
