Biological Activity
NSC57969 is a MDR-selective compound th at exhibits a robust Pgp-dependent toxic activity across diverse cancer cell lines. NSC57969 shows profound toxicity against doxorubicin resistant Brca1-/-;p53-/- spontaneous mouse mammary carcinoma cells. NSC57969 eradicates P-glycoprotein expression in doxorubicin resistant brca1-/-;p53-/- spontaneous mouse mammary carcinoma, and MES-SA/Dx5 cells. However treatment of normal cells (hCMEC/D3 cells) with NSC57969 does not induce loss of Pgp.
