(dach polymer platinate ap5346) A low molecular weight polymer-conjugated platinum complex with potential antineoplastic activity. This polymer drug delivery system consists of cytotoxic diaminocyclohexane (DACH)-platinum (Pt) coupled to a water-soluble biocompatible hydroxypropylmethacrylamide (HPMA) copolymer via a pH sensitive linker. Due to decreased pH at the tumor site, the linker is cleaved and the chelated active moiety DACH-Pt is released in tumor cells. DACH-Pt alkylates macromolecules and causes both inter- and intra-strand platinum-DNA crosslinks, which impede DNA replication and transcription, thereby resulting in cell-cycle independent cytotoxicity. The HPMA-based drug delivery system enhances the concentration of DACH-Pt at the tumor site and prolongs the half life of the agent, thereby increasing exposure and efficacy at the target tumor sites while minimizing side effects in normal tissues.NCI ThesaurusU.S. National Cancer Institute, 2021
