An efficient four-step synthesis of tetracyclic lactones from 1,4-benzodioxine-2-carboxylic acid was developed. Ellipticine derivatives exhibit antitumor activity however only a few derivatives without carbazole subunit have been studied to date. Herein, several tetracyclic lactones were synthesized and biologically evaluated. Several compounds (2a, 3a, 4a and 5a) were found to be inhibitors of the
从1,4-苯并二恶英-2-羧酸开发了一种有效的四步合成四环内酯的方法。玫瑰树碱衍生物显示出抗肿瘤活性,但是迄今为止,仅研究了少数没有咔唑亚基的衍生物。在此,合成了几种四环内酯并对其进行了生物学评估。发现几种化合物(2a,3a,4a和5a)是Kras-Wnt途径的抑制剂。内酯2a还对Tau蛋白的翻译产生有效的抑制作用,并显示具有CYP1A1生物激活的能力。获得的结果进一步证明与玫瑰树碱有关的四环内酯具有治疗潜力。分子模型研究表明,化合物2a插入KRas蛋白的螺旋α3和α4之间,并与疏水残基Phe90,Glu91,Ile9364,Hie94,
