Opis

Application

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

Biochem/physiol Actions

Ko143 has been used as a positive control inhibitor on functions of BCRP in MCF7 and BCRP over-expressing MCF7/MX100 cell lines using a BCRP prototypical substrate mitoxantrone.

Ko143 has been used as a positive control inhibitor on functions of BCRP in MCF7 and BCRP over-expressing MCF7/MX100 cell lines using a BCRP prototypical substrate mitoxantrone. The ABCG2 transporter breast cancer resistance protein (BCRP) plays an important role in disposition of many drugs and environmental toxins. Ko143 displays > 200-fold selectivity over P-gp and MRP-1 transporters. It increases intracellular drug accumulation and reverse BCRP-mediated multidrug resistance. It blocked topotecan and ABZSO transport in a concentration-dependent manner. Ko143 is reported to be a more specific inhibitor of BCRP than other known inhibitors of BCRP such as fumitremorgin C and GF120918.
