Known targets — ChEMBL curated mechanism
The experimentally established mechanism targets of Topotecan. 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
Claimed or disclosed in 11 patents. claimed = in the patent's claims; disclosed = body only.
