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.
