MedKoo CAT#: 205984

CAS#: 62816-98-2

Description: Ormaplatin is a platinum(IV) analogue with antineoplastic activity. 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. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
