  Short-term in vitro assays for tumor promoters and antitumor promoters (Epstein-Barr virus activation test) were carried out for semisynthetic quassinoids (3-7), which were obtained by esterification of the C-15 OH group of deacetylated isobrucein-B (2). All the ester derivatives showed higher antitumor promoting activity than that of the potent compound 2. A compound containing a fluorinated aliphatic ester showed the highest potency.

  对半合成喹啉类化合物（3-7）进行了肿瘤促进剂和抗肿瘤促进剂的短期体外试验（Epstein-Barr病毒激活试验），这些化合物是通过脱乙酰基异布鲁辛-B（2）的C-15 OH基团酯化获得的。所有酯类衍生物的抗肿瘤促进活性均高于强效化合物2。一种含有氟代脂肪族酯的化合物显示出最高的效力。
