⚠ Novel chemotype — no close known analogue (best Tanimoto < 0.3). Unexplored chemical space relative to ChEMBL.

Similar compounds — the chemically nearest patent molecules

Nearest neighbours by Morgan-fingerprint cosine across the patent-compound collection, with each neighbour's top predicted target and the predicted targets it shares with this molecule.

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 2207 patents — a generic fragment claimed broadly, so it's down-weighted as IP noise. Top by claim status then date:
