PNU-159682 |
Catalog No.GC36941 |
PNU-159682, a metabolite of the anthracycline Nemorubicin, is a highly potent DNA topoisomerase II inhibitor with excellent cytotoxicity. PNU-159682 acts as a more potent and tolerated?ADC cytotoxin than Doxorubicin for ADC synthesis. PNU-159682 can be used in EDV-nanocell technology to overcome drug resistance.

PNU-159682, a highly potent metabolite of the anthracycline nemorubicin with outstanding cytotoxicity, is a potent ADCs cytotoxin.
PNU-159682 inhibits a panel of human tumor cell lines with IC70 values in the range of 0.07-0.58 nM, and is 2,360- to 790-fold and 6,420- to 2,100-fold more potent than MMDX and doxorubicin, respectively[1]. PNU-159682 (100 μM) weakly inhibits topoisomerase II unknotting activity. PNU-159682 (10 μM)-DNA adducts contain one or two drug molecules bound to double-stranded DNA[2]. PNU-159682 shows cytotoxic effect on CAIX-expressing SKRC-52 cells with IC50 of 25 nM[3].
PNU-159682 (15 μg/kg, i.v.) shows antitumor activity in mice bearing disseminated murine L1210 leukemia and in MX-1 human mammary carcinoma xenografts at 4 μg/kg[1]. PNU-159682 (25 nmol/kg) exhibits a potent antitumor effect in mice bearing SKRC-52 xenografted tumors[3].
