Biochem/physiol Actions
Phenanthriplatin is a cationic monofunctional DNA-binding platinum (II) complex with significantly greater anticancer activity (IC50 in μM = 0.035/Ntera2, 0.22/A549, 0.30/HeLa, 0.59/U2OS, 0.74/PC3, 0.94/MCF7, 2.02/HT29; 72 h, MTT assay) than cisplatin, oxaliplatin, and pyriplatin. Enhanced cellular uptake due to its hydrophobic phenanthridine ligand as well as more rapid DNA covalent-binding activity both contribute to its superior anticancer efficacy. Phenanthriplatin binds more effectively to 5′-deoxyguanosine monophosphate than to N-acetyl methionine, whereas pyriplatin reacts equally to both.

Platinum drugs are a mainstay of anticancer chemotherapy. Nevertheless, tumors often display inherent or acquired resistance to platinum-based treatments, prompting the search for new compounds that do not exhibit cross-resistance with current therapies. Phenanthriplatin, cis-diamminephenanthridinechloroplatinum(II), is a potent monofunctional platinum

Phenanthriplatin, a monofunctional anticancer agent derived from cisplatin, shows significantly more rapid DNA covalent-binding activity compared to its parent complex. To understand the underlying molecular mechanism, we used single-molecule studies with optical tweezers to probe the kinetics of DNA-phenanthriplatin binding

Efficient loading of drugs in novel delivery agents has the potential to substantially improve therapy by targeting the diseased tissue while avoiding unwanted side effects. Here we report the first systematic study of the loading mechanism of phenanthriplatin and its

Transcription inhibition by platinum anticancer drugs is an important component of their mechanism of action. Phenanthriplatin, a cisplatin derivative containing phenanthridine in place of one of the chloride ligands, forms highly potent monofunctional adducts on DNA having a structure and

Cancer treatment with platinum compounds is an important achievement of modern chemotherapy. However, despite the beneficial effects, the clinical impact of these agents is hampered by the development of drug resistance as well as dose-limiting side effects. The efficacy but
