⚠ 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
Claimed or disclosed in 12 patents. claimed = in the patent's claims; disclosed = body only.
