What is 6(5H)-Phenanthridone?

The Uses of 6(5H)-Phenanthridone

6-Phenanthridone is a poly(ADP-ribose) polymerase (PARP) inhibitor with immunosuppressive effects. 6-Phenanthridone has been shown to inhibit concanavalin A-induced lymphocyte proliferation.

The Uses of 6(5H)-Phenanthridone

6(5H)-Phenanthridinone is used as a probe into the role of PARP in cellular response to irradiation. Treatment of cells with 6(5H)-Phenanthridinone and various DNA-damaging agents showed a resistance to apoptosis. It acts as a reactant in the synthesis of 5,6-dihydrophenanthridine sulfonamides, oxidative coupling with diphenylacetylene, direct copper acetate-catalyzed N-cyclopropylation of cyclic amides. It is used as HIV-1 integrase inhibitor.

General Description

6-(5H)-Phenanthridinone is an inhibitor of poly(ADP-ribose)polymerase (PARP)-1 activity. The ability of 6-(5H)-phenanthridinone to potentiate the effect of ionizing radiation on tumour cells was evaluated. Action of 6-(5H)-phenanthridinone, one of the most potent PARP inhibitor, on RDM4 murine lymphoma cells in culture was evaluated.
