PR-104 is a drug from the class of hypoxia-activated prodrugs (HAPs), [1] which is being researched as a potential anti-cancer therapeutic agent. It is a phosphate ester "pre-prodrug" that is rapidly converted to the HAP PR-104A in the body. PR-104A is in turn metabolised to reactive nitrogen mustard DNA crosslinking agents in hypoxic tissues such as found in solid tumours. [2] [3] [4] Following initial clinical studies, [5] [6] it was discovered that PR-104A is also activated by the enzyme AKR1C3, independently of hypoxia. [7] Hypoxia in the bone marrow of patients with leukaemia, [8] [9] and high activity of AKR1C3 in some leukaemia subtypes [10] [11] [12] has led to interest in clinical trials of PR-104 in relapsed refractory acute leukaemias.
