  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. The EC50 values for reversing paclitaxel resistance (141-340 nM) of LCC6MDR cells, DOX (78-590 nM) and vincristine (82-550 nM) resistance of 2008/MRP1 cells and topotecan resistance (0.9-135 nM) of HEK293/R2 and MCF7-MX100 cells were at nanomolar range. Importantly, a number of compounds displayed EC50 at or below 10 nM in BCRP-overexpressed cell lines, indicating that these bivalent triazoles more selectively inhibit BCRP transporter than the P-gp and MRP1 transporters. Most of the dimers are notably safe MDR chemosensitizers as indicated by their high therapeutic index values.

  通过一系列含有三唑桥联类黄酮二聚物的合成，使用环加成反应，利用一系列含有黄酮基团的叠氮化物（Az1-15）和炔烃（Ac1-17）构建了一个高效的化合物库。这些三唑桥联的类黄酮二聚体及其前体炔基和叠氮基类黄酮被筛选，以评估它们对过表达P-gp的细胞系（LCC6MDR）、MRP1过表达的细胞系（2008/MRP1）和BCRP过表达的细胞系（HEK293/R2和MCF7-MX100）调节多药耐药性（MDR）的能力。总体而言，它们展现了极具前景的P-gp、MRP1和BCRP介导的药物耐药性的MDR逆转活性。此外，它们显示出对各种转运体的不同程度的选择性。总体而言，它们可以分为单选择性、双选择性和多选择性的P-gp、MRP1和BCRP转运体调节剂。对于LCC6MDR细胞的紫杉醇耐药性（141-340 nM）、2008/MRP1细胞的DOX（78-590 nM）和长春新碱（82-550 nM）耐药性以及HEK293/R2和MCF7-MX100细胞的拓扑替康耐药性（0.9-135 nM），它们的EC50值处于纳摩尔范围。重要的是，许多化合物在BCRP过表达的细胞系中显示出EC50值在或低于10 nM，表明这些双价三唑更有选择性地抑制BCRP转运体而不是P-gp和MRP1转运体。大多数二聚体的治疗指数值非常高，表明它们是非常安全的MDR化疗敏感剂。
