4-Hydroxymethyl-1,6,8-trimethylfuro[2,3-h]quinolin-2(1H)-one (HOFQ) was prepared by a new profitable way, which allowed to synthesize also 4-methoxymethyl-1,6,8-trimethylfuro[2,3-h]quinolin-2(1H)-one (MOFQ), and 4-hydroxymethyl-6,8-dimethylfuro[2,3-h]quinolin-2(1H)-one (HOHFQ). Some biological activities of the three compounds were studied in comparison with 8-MOP. In the dark, they inhibited topoisomerase
通过一种新的获利方法制备了4-羟甲基-1,6,8-三甲基呋喃[2,3-h]喹啉-2(1H)-one(HOFQ),它还可以合成4-甲氧基甲基-1,6, 8-三甲基呋喃[2,3-h]喹啉-2(1H)-one(MOFQ)和4-羟甲基-6,8-二甲基呋喃[2,3-h]喹啉-2(1H)-one(HOHFQ) 。与8-MOP相比,研究了这三种化合物的某些生物活性。在黑暗中,它们抑制拓扑异构酶II,从而在哺乳动物细胞中产生中等程度的抗增殖活性。还通过在哺乳动物细胞中用UVA照射测试了抗增殖活性:所有化合物均显示出比8-MOP更高的活性,没有致突变性和皮肤光毒性,HOFQ的最佳结果。研究了与DNA的光结合,与呋喃香豆素相比,这些呋喃喹啉酮具有不同的序列特异性。
