Razoxane and dexrazoxane are two novel drugs with some uniquely
useful features. They block cell division at the G2/M border, but
nowhere else, so that they have a low toxicity profile. They
suppress tumor metastasis and haemorrhages through normalization of
pathological blood vessels. Razoxane potentiates radiotherapy
especially in the treatment of soft tissue sarcomas and
gastrointestinal neoplasms. They protect normal tissues against
toxic chemicals, e.g. the myocardium against anthracyclines or
subcutaneous tissue against injuries caused by incidental
extravasations of anthracyclines. Dexrazoxane is the only drug
approved by the FDA/EMEA for the specific purpose of preventing
cardiac damage when giving the widely used and effective antitumor
anthracyclines. The reduction of cardiotoxicity is achieved without
response reduction or reducing of time to progression of tumors.
While the full analysis of their actions at the molecular level is
not yet completely understood, it seems most likely that it is via
an inhibition on the topoisomerase II a. Moreover, the drugs have
the ability to chelate several metals including iron, copper or
zinc. The protection of normal tissues is nowhere more important
than that of brain, and there are indications that the proteins
thought to be responsible for the ravages of Alzheimers disease
could be stabilized by one or both these drugs.
