  Synthesis and biological evaluation of new 1,5-diazaanthraquinones with cytotoxic activity

  摘要：

  series of 1,5-diazaanthraquinone derivatives was synthesized and their in vitro cytotoxic activities were evaluated against several human cancer cell lines. The 1,5-diazaanthraquinone chromophore has been synthesized either on the basis of hetero Diels-Alder reactions involving different quinoline-5,8-diones and alpha,beta,-unsaturated aldehyde N,N-dimethylhydrazones or by thertmolysis of different arylaminotnethylene Meldrntm's acid derivatives. Some of these compounds showed cytotoxic activity comparable to that of mitoxantrone against most of the cell lines tested. Compounds 20, 30, 31 and 37 were 4-54 times more potent that mitoxantrone against A549, H 116, PSN 1 and T98G cancer cell lines but, interestingly, they were 3-16 times less potent against the human breast carcinoma SKBR3. Some structure-activity relationships are described, the most significant one being the increase in cytotoxicity resulting from the introduction of a halogen atom at the C-4 position.

• A C-Ring Regioisomer of the Marine Alkaloid Meridine Exhibits Selective In Vitro Cytotoxicity for Solid Tumours

  日期：2001.7

  9-Hydroxybenzo[b]pyrido[4,3,2-de](1,10)-phenantrolin-8-one (1), a regioisomer of the marine alkaloid meridine, was synthesized from 5,8-dimethoxy-6-nitro-4(1H)-quinolinone in eight steps and 23% overall yield. A shorter route was also investigated, based on the hetero Diels-Alder reaction between o-nitrocinnamaldehyde dimethylhydrazone and 4-halogen-6-bromo-5,8-quinolinequinones followed by reductive cyclization onto the C-5 carbonyl of the quinone. Compound 1 showed a remarkable in vitro cytotoxicity, with a pattern of selectivity towards solid rumours that is not found in the reference alkaloid, the activity against the human lung carcinoma (A-549) being particularly noteworthy. The activities of meridine and compound 1 as inhibitors of topoisomerase II were also significantly different. (C) 2001 Elsevier Science Ltd. All rights reserved.
