“BITC, PEITC , and 1-NITC significantly increased the 2-h accumulation of DNM in MCF-7/ADR (P-gp overexpression), PANC-1 (MRP1 overexpression), and human colon adenocarcinoma Caco-2 cells (except for 1-NITC).”
“…,PEITC, … DNM ; (2) PEITC and/or its conjugates do not represent P-gp substrates; (3) BITC and PEITC, but not 1-NITC, inhibit MRP1 through the … (4) PEITC and/or its conjugates are MRP1 substrates so binding interactions with DNM represent a second potential mechanism involved in MRP1 inhibition.”
