A series of cis and trans bicyclic lactones was prepared as congeners of podophyllotoxin (1) and evaluated as antimitotic agents both in cell cultures grown in vitro and in an in vitro protein binding assay. All compounds displayed insignificant activity-a result which may reflect insufficient structural similarity to podophyllotoxin or which may be interpreted as in agreement with previous observations
制备了一系列的顺式和反式双环内酯作为
鬼臼毒素(1)的同源物,并在体外培养的
细胞培养物中和体外蛋白质结合测定中均被评价为抗有丝分裂剂。所有化合物均显示出微不足道的活性-该结果可能反映了与
鬼臼毒素的结构相似性不足,或者可能被解释为与先前对1定义的抗有丝分裂活性的立体
化学要求的观察结果一致。
