Fig. 6From: Inhibitory effects of lapachol on rat C6 glioma in vitro and in vivo by targeting DNA topoisomerase I and topoisomerase IIEffects of lapachol on TOP I and TOP II activities by the conversion of supercoiled pBR322 DNA to its relaxed form. TOP I and TOP II drug screening kits were used. a TOP I inhibition assay result by lapachol; b TOP II inhibition assay result by lapachol. The known TOP I inhibitor camptothecin and TOP II poisons etoposide were used as positive controlsBack to article page
