β-Lapachone
Chemical Name: 3,4-Dihydro-2,2-dimethyl-2H-naphtho[1,2-b]pyran-5,6-dione
Purity: ≥98%
Biological Activity
β-Lapachone is a DNA topoisomerase I inhibitor. Exhibits a different inhibitory mechanism to camptothecin (Cat. No. 1100). Induces apoptosis in a variety of cell lines, including prostate cancer and promyelocytic leukemia cells; blocks the cell cycle in G0/G1. Also has effects on DNA topoisomerase II, NF-κB, AP-1, and JNK.Technical Data
