Synthesis and in vitro evaluation of 1,8-diazaanthraquinones bearing 3-dialkylaminomethyl or 3-(N-alkyl- or N-aryl)carbamoyloxymethyl substituent
摘要:
A series of 1,8-diazaanthraquinone derivatives carrying a 3-dialkylaminomethyl or a 3-(N-alkyl or aryl)carbamoyloxymethyl substituent was synthesised and their in vitro cytotoxic activities were evaluated against eight human cancer cell lines (HOP62, SK-OV-3, HCT-15, SF295, MCF7, SNU-354, KB-3-1 and KB-V-1). A number of compounds including 8c, 8d and 11c showed cytotoxic activity comparable to that of doxorubicin against all human cancer cell lines tested. The compounds 8c and 8d were 2100 times more potent than doxorubicin against HCT-15, MCF7 and SNU-354 cancer cell lines. Furthermore, these compounds retained considerable cytotoxic activity against the doxorubicin-resistant cell line KB-V-1, implying their therapeutic potential to treat doxorubicin-resistant tumours. These compounds inhibited topoisomerase II-mediated DNA relaxation in vitro, suggesting that this inhibitory effect be attributable to their cytotoxicity.

Synthesis and in vitro cytotoxicity of 3-substituted-1,8-diazaanthraquinones produced by Lewis-acid catalyzed hetero diels-alder reaction
摘要:
A hetero Diels-Alder reaction of quinoline-5,8-dione with 1-(N,N-dimethylamino)-3-methyl-1-aza-1,3-butadiene proceeded to give 3-methyl-1,8-diazaanthraquinone (100% regioselectivity) in the presence of Lewis-acid catalyst (ZnCl(2) or ZnBr(2)). Subsequent functionalizations of the benzylic methyl group resulted in the 1,8-diazaanthraquinone analogues as potential antitumor agents. The most active compound, 8, exhibited in vitro cytotoxic activity comparable to that of doxorubicin. (C) 1998 Elsevier Science Ltd. All rights reserved.
