cell lines were recorded and compared with those observed for the parent molecules 1 and 2. Some of the analogues displayed powerful antiproliferative effects on selected human tumour cell lines, but all of them were devoid of any cytotoxicity towards the normal foetal lung fibroblasts (MRC-5). A SAR study reveals the structural features of these lactones that may increase their antiproliferative activity

细胞系显示出强大的抗增殖作用,但它们都没有对正常胎儿肺成纤维细胞(MRC-5)的任何细胞毒性。
SAR研究表明,这些内酯的结构特征可能会增强它们的抗增殖活性。
