upon IR and NMR (1H and 13C) spectroscopy as well as high resolution mass spectrometry analyses. Structures of compounds 1, 4 and 16 were also investigated by X-ray analysis. The synthesized compounds were submitted to in vitro bioassays against HL-60, K562 and NALM6 cancer cell lines using MTT cytotoxicity assay. After 48 h of treatment, twelve derivatives were able to reduce cell viability and presented
在本研究中,合成了十九个3-(2-芳基-2-氧代乙基)异苯并呋喃-1(3 H)-的集合,并筛选了它们对一组三种白血病癌细胞系的细胞毒活性。这些化合物是通过ZrOCl 2 ·8H 2 O催化的邻苯二甲酸和不同的苯乙酮之间的缩合反应制备的。该反应在无溶剂的条件下进行,获得了高产率(80-92%)的异苯并呋喃-1(3 H)-一。通过IR和NMR(1 H和13 C)光谱以及高分辨率质谱分析来确认合成的化合物的身份。化合物的结构1,4和16也通过X射线分析调查。使用MTT细胞毒性测定法将合成的化合物用于针对HL-60,K562和NALM6癌细胞系的体外生物测定。处理48小时后,十二种衍生物能够降低细胞活力,并且对至少一种评估谱系的IC 50值等于或低于20μmolL -1。最活跃的化合物对应于3-(3-甲基苯基-2-氧代乙基)异苯并呋喃-1(3 ħ) -酮(18)(IC 50个为HL-60获得的值,K562和NALM6分别为13
