Pentamethoxymorin
Pentamethoxymorin (MRS923) is a selective breast cancer resistance protein (BCRP/ABCG2) inhibitor. Pentamethoxymorin shows selectivity for BCRP over P-gp and MRP1. Pentamethoxymorin inhibits MDCK BCRP cells with IC50 vaues of 5.98 μM and 5.94 μM in Hoechst 33342 (HY-15559) assay and Pheophorbide A (HY-125665) assay, respectively. Pentamethoxymorin can be used for the study of ccancer.
