  Antitumor Agents. 293. Nontoxic Dimethyl-4,4′-dimethoxy-5,6,5′,6′-dimethylenedioxybiphenyl-2,2′-dicarboxylate (DDB) Analogues Chemosensitize Multidrug-Resistant Cancer Cells to Clinical Anticancer Drugs

  摘要：

  Novel dimethyl-4,4'-dimethoxy-5,6,5',6'-dimethylenedioxybipheny1-2,2'-dicarboxylate (DDB) analogues were designed and synthesized to improve their chemo-sensitizing action on KBvin (vincristine-resistant nasopharyngeal carcinoma) cells, a multidrug resistant cell line overexpressing P-glycoprotein (P-gp). Structure-activity relationship analysis showed that aromatic and bulky aliphatic side chains at the 2,2'-positions effectively and significantly sensitized P-gp overexpressing multidrug resistant (MDR) cells to anticancer drugs, such as paclitaxel (TAX), vincristine (VCR), and doxorubicin (DOX). DDB derivatives 16 and 23 showed 5-10 times more effective reversal ability than verapamil (VRP) for TAX and VCR. Analogue 6 also exhibited five times greater chemosensitizing effect against DOX than VRP. Importantly, no cytotoxicity was observed by the active DDB analogues against both non-MDR and MDR cells, suggesting that DDB analogues serve as novel lead compounds for the development of chemosensitizers to overcome the MDR phenotype. The mechanism of action studies demonstrated that effective inhibition of P-glycoprotein by DDB analogues dramatically elevated the cellular concentration of anticancer drugs.

  Anti-AIDS (Acquired Immune Deficiency Syndrome) Agents. 17. New Brominated Hexahydroxybiphenyl Derivatives as Potent Anti-HIV Agents

  摘要：

  Sixteen biphenyl derivatives were synthesized and evaluated for their inhibitory activity against HIV-1 replication in acutely infected H9 cells. 3-Bromo- (4) and 3,3'-dibromo-4,4'-dimethoxy-5,6,5',6'-bis(methylenedioxy)-2,2' -bis(methoxycarbonyl)biphenyl (5) demonstrated potent anti-HIV activity with EC(50) values of 0.52 and 0.23 mu g/mL and therapeutic index values of > 190 and > 480, respectively. A comparison, of the anti-HIV activity of these biphenyl derivatives suggested that the types of substituents on the phenolic hydroxy groups rather than the number of bromine(s) on the aromatic rings are important to the enhanced anti-HIV activity. Compounds 4 and 5 also showed potent inhibitory activity against HIV-1 reverse transcriptase in a template-primer dependent manner. The site of inhibition of HIV could be related to inhibition of this enzyme. Compounds 4 and 5 did not induce virus expression from the chronic HIV-1-infected cell lines ACH-2 and U1. Furthermore, these two agents did not inhibit an increase in virus production from the chronic HIV-1-infected cell lines when the phorbol ester PMA was present.

  Since the discovery of 2,2'-dimethoxycarbonyl-4,4-dimethoxy-5,6,5',6'-biomethylenedioxy-biphenyl (DDB) as a potent anti-HBV agent, we have studied the structure-activity relationships of 4,4'-dimethoxy -5,6,5',6'-dimethenedioxy-2-alkyloxycarbonyl-2'-(4- substituted benzyl piperazin-1-yl)carbonyl-biphenyl as anti-HBV agents. Therefore, it is rational to extend this study to the 3,3'-disustituted-4,4'-dimethoxy5,6,5',6'-dimethenedioxy-2-alkyloxycarbonyl-2'-Serine derivatives. Thus, in an attempt to develop an efficient method for the preparation of a large number of DDB derivatives, the reaction between a DDB acid chloride and serine derivatives on solid support was studied. The structure of resulted compounds was confirmed by LC-MS and H-1 NMR analysis. Compounds 2a, 2d, 2f, 2j showed in vitro anti-HBV activity without significant toxicity up to 100 mu M.
