Ormaplatin (NSC 363812, tetraplatin) is a stable platinum (IV) analog. Ormaplatin alkylates DNA, forming both inter- and intra-strand platinum-DNA crosslinks, which result in inhibition of DNA replication and transcription and cell-cycle nonspecific cytotoxicity. Ormaplatin showed marked antitumor activity both in vitro and vivo. The severe, cumulative and irreversible peripheral neurotoxicity observed in phase I studies resulted in termination of further clinical development of ormaplatin.
