  Bis-pyranobenzoquinones as a New Family of Reversal Agents of the Multidrug Resistance Phenotype Mediated by P-Glycoprotein in Mammalian Cells and the Protozoan Parasite Leishmania

  摘要：

  We have synthesized a set of bis-pyranobenzoquinones through a direct and highly efficient approach based on a double intramolecular domino Knoevenagel hetero Diels-Alder reaction. These bis-pyranobenzoquinone derivatives are compounds whose skeletons have similarities to those of some anticancerous and leishmanicidal drugs. Considering that these drugs are substrates for some members of the ATP-binding cassette (ABC) family of proteins that confers a multidrug resistance (MDR) phenotype, we have carried out the biological evaluation of 20 bis-pyranobenzoquinones as modulators of the MDR phenotype in mammalian cell lines overexpressing P-glycoprotein, MRP1, or BCRP. Moreover, we also tested some of these compounds as potential MDR modulators in a Leishmania tropica line overexpressing a P-glycoprotein-like transporter. Compounds 9 and 10 are, in this work, the most promising reversal agents of MDR in human cancer cell lines, while compounds 4 and 20 showed potent reversal activity of MDR phenotype in the protozoan parasite Leishmania.
