P-gp inhibitor 5 is a potent P-glycoprotein (P-gp) inhibitor. P-gp inhibitor 5 has antiproliferative activity against certain cancer cell lines. P-gp inhibitor 5 is effective in reversing the multidrug resistance (MDR) phenotype in ABCB1/Flp-InTM-293 and KBvin cells by restoring their sensitivity to Vincristine (HY-N0488A) and Paclitaxel (HY-B0015).

In Vitro

P-gp inhibitor 5 (compound 10) has cytotoxic against ABCB1/Flp-InTM-293 and KBvin cells with IC50s of 29.7 and 12.6 μM, respectively[1].
P-gp inhibitor 5 (2.5 and 5 μM) lows the IC50s of KBvin cells for Vincristine to 7.59~36.82 nM, for Paclitaxel to 21.0~79.5 nM, for Doxorubicin to 85.7~111 nM; lows the IC50s of HeLaS3 cells for Vincristine to 2.24~3.91 nM, for Paclitaxel to 8.81~9.58 nM, for Doxorubicin to 102~1260 nM[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
