Description

General description

A potent inhibitor poly(ADP-ribose) polymerase (PARP; IC₅₀ = 0.40 µM). Has been shown to potentiate the cytotoxicity of the DNA-methylating agent MTIC [5-(3-N-methyltriazen-1-yl)-imidazole-4-carboxamide] and ionizing irradiation in murine L210 leukemia cells.

A potent poly(ADP-ribose) polymerase (PARP) inhibitor (IC₅₀ = 400 nM) that potentiates the cytotoxicity of various DNA-active agents, including the DNA-methylating compound MTIC [5-(3-N-methyltriazen-1-yl)-imidazole-4-carboxamide], the DNA strand break-inducing drug temozolomide, topotecan, bleomycin, and ionizing radiation in murine L1210 leukemia cells, Chinese hamster ovary cells, and in a variety of human tumor cell lines.
