Known targets — ChEMBL curated mechanism
The experimentally established mechanism targets of Morphine. The predicted profile below is derived independently by chemical similarity — agreement is a validation signal, a miss is honest.

Similarity is cosine over the 2,048-bit Morgan fingerprint (≈ Tanimoto). Identical fingerprints score 1.00.
Patent provenance — the patents this molecule appears in, and who filed them
Appears in 141090 patents — a generic fragment claimed broadly, so it's down-weighted as IP noise. Top by claim status then date:
