Abstract: The present disclosure provides methods and composition for treating multi-drug resistant cancers, in particular, breast cancers, via administration to a subject the composition including a peptide having a sequence complementary to a highly conserved motif present in substantially all integrins responsible for an integrin-mediated attachment-independent chemoresistance to one or more chemotherapeutic agents. The binding of the sequence of the peptide to the highly conserved motif will enhance accumulation of the chemotherapeutic agents in the tumor-initiating cells and in turn restores the function of the chemotherapeutic agents in the tumor-initiating cells.

Abstract: A triazole bridged flavonoid dimer compound library was efficiently constructed via the cycloaddition reaction of a series of flavonoid-containing azides (Az 1-15) and alkynes (Ac 1-17). These triazole bridged flavonoid dimers and their precursor alkyne- and azide-containing flavonoids were screened for their ability to modulate multidrug resistance (MDR) in P-gp-overexpressed cell line (LCC6MDR), MRP1-overexpressed cell line (2008/MRP1) and BCRP-overexpressed cell line (HEK293/R2 and MCF7-MX100). Generally, they displayed very promising MDR reversal activity against P-gp-, MRP1- and BCRP-mediated drug resistance. Moreover, they showed different levels of selectivity for various transporters. Overall, they can be divided into mono-selective, dual-selective and multi-selective modulators for the P-gp, MRP1 and BCRP transporters.
