Introduction of 4707-32-8 :

β-Lapachone (ARQ-501;NSC-26326) is a naturally occurring O-naphthoquinone, acts as a topoisomerase I inhibitor, and induces apoptosis by inhibiting cell cycle progression. IC50 & Target: Topoisomerase I[1] In Vitro: β-Lapachone is a topoisomerase I inhibitor. β-Lapachone (25 μM) inhibits camptothecin-induced DNA cleavage[1]. β-Lapachone (10-40 μM) significantly reduces the colony-forming ability of CHO cells, and is cytotoxic in S phase. β-Lapachone at above 10 μM, causes a heavy DNA-strand breaks in CHO cells[2]. β-Lapachone (10 μM) suppresses JCPyV replication in IMR-32 cells. β-Lapachone (1.0 µM) potently affects JCPyV propagation in JCI cells. β-Lapachone (0.01-0.1 μM) inhibits VP1 production in JCI cells[4]. In Vivo: β-Lapachone (0.066%) ameliorates cisplatin-induced renal injury and when in combination with cisplatin, the affect is more significant in mice. β-Lapachone increases Mre11-Rad50-Nbs1 (MRN) complex expression in mice[3].
