Ko 143 Chemical Properties,Usage,Production

  • Description Breast cancer resistance protein (BCRP) is an ATP-binding cassette protein known also as ABCG2. While it normally functions as a high-capacity urate exporter in the renal system, it also acts as a xenobiotic transporter and contributes to multidrug resistance (e.g., to mitoxantrone) in certain types of cancer. BCRP is abundant at the intestinal epithelium and blood-brain barrier, potentially restricting the distribution of certain drugs. Ko 143 is a potent and selective inhibitor of BCRP, preventing the export of mitoxantrone and topotecan in breast cancer cell lines (EC50s = 23 and 26 nM, respectively). It is much less effective at the transporters P-glycoprotein and multidrug resistance-associated protein 1, MRP1. Ko 143 is effective in vivo in mice.
  • Uses A potent BCRP (breast cancer resistance protein) inhibitor
  • Uses Ko143 hydrate has been used:
    • to determine the role of ATP-binding cassette sub-family G member 2 (ABCG2), human embryonic kidney (HEK)-C1 and HEK-ABCG2 in tumor microenvironment
    • to inhibit ABCG2 for sphere formation assay
    • in calcein-AM efflux inhibition to monitor multidrug resistance protein (MRP)-function in kidney
    • for cell viability assay

  • Definition ChEBI: LSM-6260 is a member of beta-carbolines and a tert-butyl ester.
  • Biological Activity Potent and selective breast cancer resistance protein multidrug transporter (BCRP) inhibitor (EC 90 = 26 nM). Displays > 200-fold selectivity over P-gp and MRP-1 transporters. Increases intracellular drug accumulation and reverses BCRP-mediated multidrug resistance.
  • Biochem/physiol Actions Ko143 has been used as a positive control inhibitor on functions of breast cancer resistance protein (BCRP) using a BCRP prototypical substrate mitoxantrone. BCRP, an ABCG2 transporter, plays an important role in disposition of many drugs and environmental toxins. Ko143 displays > 200-fold selectivity over P-gp and MRP-1 transporters and thus is more specific than other known BCRP inhibitors such as fumitremorgin C and GF120918. It increases intracellular drug accumulation and reverses BCRP-mediated multidrug resistance. It blocks topotecan and ABZSO transport in a concentration-dependent manner.
