Use of an abc transporter peptide inhibitor

Abstract

Disclosed herein is a use of an adenosine triphosphate (ATP) binding cassette (ABC) transporter peptide inhibitor HX-12C. This disclosure also discloses a method of treating a tumor with multidrug resistance mediated by the ABC transporter using a combination of the peptide HX-12C shown in SEQ ID NO: 1 and an ABC transporter substrate chemotherapeutic drug. Moreover, this disclosure also provides a composition for treating a tumor with multidrug resistance mediated by an ABC transporter, consisting of the peptide HX-12C shown in SEQ ID NO: 1 and an ABC transporter substrate chemotherapeutic drug.
