  Synthesis of tetrahydrobenzoxazepine acetals with electron-withdrawing groups on the nitrogen atom. Novel scaffolds endowed with anticancer activity against breast cancer cells

  摘要：

  Synthetic approaches that have led to (RS)-3-methoxy-N-substituded-1,2,3,5-tetrahydro-4,1-benzoxazepines with different electron-withdrawing groups, and (RS)-2-methoxy-N-trifluoroacetyl-2,3,4,5-tetrahydro-1,4-benzoxazepine are described. These novel synthons that were designed to be used as scaffolds for the preparation of new 0,N-acetals as anticancer agents, unexpectedly proved to show antiproliferative activity against the MCF-7 breast cancer cell line. It has been found that substituents on the nitrogen atom have an influence on biological activity. In particular, the presence of a trifluoroacetyl moiety on the nitrogen atom leads to amides displaying interesting in vitro antitumour activities. (C) 2004 Elsevier Ltd. All rights reserved.

  derivatives for the Lewis acid mediated condensation reaction with pyrimidine bases to give O,N-acetals. Acetonitrile, stannic chloride, 50 °C, and a reaction time higher than 48 h are the optimum conditions for such condensation reactions. Under these conditions, 5-fluorouracil preferably links to the aminalic carbon through its N-1‘ ‘ position, while the attachment of the uracil fragment is through N-3‘ ‘

  Completing an SAR study, a series of (RS)-6-substituted-7- or 9-(1,2,3,5-tetrahydro-4,1-benzoxazepine-3-yl)-7H or 9H-purines has been prepared under microwave-assisted conditions. Their antiproliferative activities on MCF-7 and MDA-MB-231 cancerous cell lines are presented, being the majority of the IC50 values below 1 mu M. The most active compound (RS)-2,6-dichloro-9-[1-(p-nitrobenzenesulfonyl)-1,2,3,5-tetrahydro-4,1- benzoxazepin-3-yl]-9H-purine (14) presents an IC50 of 0.166 mu M against the human cancerous cell line MDA-MB-231. Compound 14 was the most selective against the human breast adenocarcinoma MCF-7 and MDA-MB-231 cancer cell lines (Therapeutic Indexes, TIs = 5.1 and 11.0, respectively) in relation to the normal one MCF-10A. (RS)-14 was resolved into its enantiomers. Both enantiomers are equally potent, but more potent than the corresponding racemic mixture. (R)-14 induces apoptosis against MCF-7 up to 52.50% of cell population after 48 h, being more potent than the clinical-used drug paclitaxel (43%). (RS)-14 induces no acute toxicity in mice after two weeks of treatment. (C) 2010 Elsevier Masson SAS. All rights reserved.
