Griseofulvin, 12-O-tetradecanoyl phorbol-13-acetate, melittin, epidermal growth factor, vinblastine, cytochalasin B, podophyllotoxin, colcemid, and colchicine were unable to transform cells but could increase from 8- to 40-fold the frequency of cell transformation by polyoma virus. The 3T3-like cells were resting at confluence and were exposed to the drug only during the 1st week after viral infection. Griseofulvin, a tumor promoter, reduced or increased the frequency of transformation depending on the dose with which the infected cells were treated. The antitumor activity of tumor promoters is discussed.
灰黄霉素、12 - O - 十四烷酰佛波醇 - 13 - 乙酸酯、蜂毒肽、表皮生长因子、长春碱、细胞松弛素B、鬼臼毒素、秋水仙酰胺和秋水仙碱均无法诱导细胞转化,但可使多瘤病毒诱导的细胞转化频率提高8至40倍。3T3样细胞在汇合时处于静止状态,仅在病毒感染后的第1周接触药物。肿瘤促进剂灰黄霉素根据处理感染细胞的剂量不同,可降低或提高转化频率。文中讨论了肿瘤促进剂的抗肿瘤活性。
