  Flavonoid Dimers as Bivalent Modulators for P-Glycoprotein-Based Multidrug Resistance:  Synthetic Apigenin Homodimers Linked with Defined-Length Poly(ethylene glycol) Spacers Increase Drug Retention and Enhance Chemosensitivity in Resistant Cancer Cells

  摘要：

  Much effort has been spent on searching for better P-glycoprotein- ( P-gp-) based multidrug resistance ( MDR) modulators. Our approach was to target the binding sites of P-gp using dimers of dietary flavonoids. A series of apigenin-based flavonoid dimers, linked by poly( ethylene glycol) chains of various lengths, have been synthesized. These flavonoid dimers modulate drug chemosensitivity and retention in breast and leukemic MDR cells with the optimal number of ethylene glycol units equal to 2-4. Compound 9d bearing four ethylene glycol units increased drug accumulation in drug-resistant cells and enhanced cytotoxicity of paclitaxel, doxorubicin, daunomycin, vincristine, and vinblastine in drug- resistant breast cancer and leukemia cells in vitro, resulting in reduction of IC50 by 5-50 times. This compound also stimulated P-gp's ATPase activity by 3.3-fold. Its modulating activity was presumably by binding to the substrate binding sites of P-gp and disrupting drug efflux.

  Multidrug resistance (MDR) is a major problem in cancer chemotherapy. The best characterized resistance mechanism is the one mediated by the over-expression of drug efflux transporters, permeability-glycoprotein (P-gp), which pump a variety of anticancer drugs out of the cells, resulting in lowered intracellular drug accumulation. A series of flavonoid dimers are developed in this invention, which are linked together by linker groups of various lengths. These flavonoid dimers are found to be efficient P-gp modulators that increase cytotoxicity of anticancer drugs in vitro and dramatically enhance their intracellular drug accumulation. It is found that the flavonoid dimers of this invention is also useful in reducing drug resistance in treating parasitic diseases.

  多药耐药性（MDR）是癌症化疗中的主要问题。最好表征的耐药机制是通过过度表达药物外流转运蛋白、渗透性糖蛋白（P-gp）介导的耐药机制，它将各种抗癌药物泵出细胞，导致细胞内药物积累降低。本发明开发了一系列由不同长度的连接基团连接在一起的类黄酮二聚体。发现这些类黄酮二聚体是有效的P-gp调节剂，可以增加抗癌药物在体外的细胞毒性并显著提高它们的细胞内药物积累。同时，发现本发明的类黄酮二聚体也有助于减少治疗寄生虫病的耐药性。
