A convenient synthesis of the pyrrolo[3,4-h]quinazolineringsystem is reported. Our synthetic approach consisted of the annelation of a pyrimidine ring to an isoindole moiety using tetrahydroisoindole-4-ones as building blocks. The antiproliferative activity of the new compounds was investigated and one of them showed antitumor activity against all the 59 tested cell lines at micromolar concentrations
报道了吡咯并[3,4- h ]喹唑啉环系统的方便合成。我们的合成方法包括使用四氢异吲哚-4-酮作为构建基,使嘧啶环与异吲哚部分成环。研究了新化合物的抗增殖活性,其中一种在微摩尔浓度(1.46-18.4μM)下显示了对所有59种测试细胞系的抗肿瘤活性。
Synthesis of a new class of pyrrolo[3,4-h]quinazolines with antimitotic activity
A new series of pyrrolo[3,4-h]quinazolines was conveniently prepared with a broad substitution pattern. A large number of derivatives was obtained and the cellular cytotoxicity was evaluated in vitro against 5 different human tumor cell lines with GI(50) values reaching the low micromolar level (1.3-19.8 mu M). These compounds were able to induce cell death mainly by apoptosis through a mitochondrial dependent pathway. Selected compounds showed antimitotic activity and a reduction of tubulin polymerization in a concentration-dependent manner. Moreover, they showed anti-angiogenic properties since reduced in vitro endothelial cell migration and disrupted HUVEC capillary-like tube network in Matrigel. (C) 2013 Elsevier Masson SAS.
