  • Patent number: 11661404
    Abstract: AKR1C3-activated prodrugs of Formula (I), pharmaceutical compositions comprising prodrugs of Formula (I), and their use in the treatment of hyperproliferative diseases such as cancer and for cell ablation. The compounds of the invention are able to penetrate neoplasm tissue and be selectively reduced to an active (cytotoxic) form by contact with an AKR1C3 enzyme found in the neoplasm. This active form is therefore able to ablate AKR1C3-expressing target cells of the neoplasm and therefore has particular utility in the treatment of cancer and other hyperproliferative disorders.
