本申請案為發現一個新穎化學結構式具有抗癌活性。已完成化學合成步驟、離體細胞抗癌活性、以及活體動物抗腫瘤活性測試,並發現可以抑制CDK4酵素活性,擬申請新抗癌化合物及製程專利。 我們設計與合成一系列新穎3-亞烯吲哚酮 乙醯胺抗癌化合物,這一系列的化合物於抑制癌細胞株生長活性中,有較靛玉紅-3’-肟更佳的抗癌活性並與抗癌候選藥物roscovitine活性相當,此系列衍生物中化合物10為抗癌活性較佳的化合物。在細胞週期的調控分析中顯示化合物10能夠抑制細胞週期在G1期並造成細胞週期sub-G1分佈增加,亦說明了此類化合物造成癌細胞死亡是經由細胞凋零的路徑。 化合物10對大腸癌CT26細胞移植腫瘤生長老鼠試驗中顯示,化合物10與抗癌藥物順鉑效果相近,均能夠有效的縮減腫瘤的大小,但是化合物10並沒有明顯的體重下降情形亦說明了化合物10沒有顯注的副作用情形。 We designed and synthesized a series of 3-ylideneoxindole acetamides as novel anticancer agents. The acetamides were then evaluated for in vitro and in vivo anticancer activities. These acetamides were found to have better anticancer activity than was indirubin-3'-oxime in several cancer cell lines and also displayed a spectrum of activity similar to that of the drug candidate roscovitine, a CDK inhibitor. Among the 3-ylideneoxindole acetamides, compound 10 showed particularly good efficacy. Cell cycle analysis further revealed that compound 10 arrested cells in the G1 phase and caused an increase in the sub-G1 population, indicating that the apoptosis pathway had been induced. In testing the therapeutic potency of compound 10 on CT26-xenografted BALB/c mice, a significant reduction in tumor size comparable to that of cisplatin was found when administrated via the i.p. route. The mice presented no loss of body weight, indicating that this compound possesses low toxicity.
