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