Additional Information

Pipobroman was approved in German. Pipobroman is an antineoplastic agent. Specifically it is a piperazine derivative with a chemical structure close to that of many DNA alkylating agents. Pipobroman has well documented clinical activity against polycythemia vera and essential thrombocythemia. According to drugbank, pipobroman was indicated for the treatment of polycythaemia vera and refractory chronic myeloid leukaemia.
The mechanism of action is uncertain but pipobroman is thought to alkylate DNA leading to disruption of DNA synthesis and eventual cell death.
