本发明的式(1)化合物具有重要的生物活性，体外对人白血病细胞(k562)的细胞毒性试验表明：此类式(1)所示的结构的二氢香豆素骨架拼接硫代吡咯啉酮螺环氧化吲哚化合物对肿瘤细胞生长具有抑制作用，有可能发展成为新的防治肿瘤药物。但需强调的是本发明的化合物不限于人白血病细胞(k562)表示的细胞毒性。

药理实施例：化合物3i-1,3e-1,3l-1,3m-1和3o-1对k562细胞的细胞毒性

k562(人慢性髓系白血病细胞)用rpmi-1640培养基培养，培养基中含10％的胎牛血清，100u/ml的青霉素和100u/ml链霉素。细胞以每孔5000个细胞的浓度加入到96孔中，在37℃含5％co2潮湿空气的培养箱中培养24小时。

细胞存活率的测定用改良mtt法。细胞经过24小时的孵育后，分别将新配的化合物3i-1,3e-1,3l-1,3m-1和3o-1的二甲基亚砜溶液以浓度梯度加入到各孔中，使孔中化合物最终浓度分别为5μmol/l,10μmol/l,20μmol/l,40μmol/l和80μmol/l。48小时后，每孔加入10μlmtt(5mg/ml)的磷酸盐缓冲液，再继续在37℃培养4小时后，离心5分钟除去未转化的mtt，每孔中加入150μl二甲基亚砜。以溶解还原的mtt晶体甲臜(formazan)，用酶标仪在490nm波长测定od值。其中化合物3i-1,3e-1,3l-1,3m-1和3o-1对k562细胞半抑制浓度ic50由spss软件(19版本)分析得到。化合物3i-1对k562肿瘤细胞的ic50为35.57μmol/l；化合物3e-1对k562肿瘤细胞的ic50为23.42μmol/l；化合物3l-1对k562肿瘤细胞的ic50为27.73μmol/l；化合物3m-1对k562肿瘤细胞的ic50为41.87μmol/l；化合物3o-1对k562肿瘤细胞的ic50为39.54μmol/l；而阳性对照顺铂对k562肿瘤细胞的ic50为21.01μmol/l。

实验结论：k562细胞是测试化合物对肿瘤细胞的细胞毒性的有效工具和评价指标。本实验表明此类式(1)所示的二氢香豆素骨架拼接硫代吡咯啉酮螺环氧化吲哚化合物对k562细胞具有较强的细胞毒性，和肿瘤治疗一线用药顺铂同一数量级，有可能发展成新的具有抗肿瘤作用的药物。

从以上药理实施例中我们可以看出这些化合物对人白血病细胞(k562)都显示有一定的细胞毒性。可见这些化合物具有开发成为抗肿瘤药物的潜力，值得继续深入研究下去。
