摘要:

利用N-甲基吲哚对类固醇药物的前驱体16-脱氢孕烯醇酮乙酸酯(16-DPA)的D环C16位进行修饰, 采用ZrCl4-乙酸乙酯廉价催化体系, 合成了16个3β-乙酰氧基-16α-3'-吲哚孕烯醇酮化合物和6个3β-羟基-16α-3'-吲哚孕烯醇酮衍生物. 该方法具有收率高、 立体选择性好和底物适应性强等优点. 通过噻唑蓝(MTT)比色法测试了22个化合物对三阴性乳腺癌细胞(MDA-MB-231)的抗肿瘤活性. 初步测试结果表明, 3β-乙酰氧基-16α-3'-吲哚孕烯醇酮化合物6h和6i对MDA-MB-231癌细胞有较好的抑制活性, 其半数抑制浓度(IC50)分别为18.07和23.22 μmol/L; 而化合物7a~7f均对MDA-MB-231癌细胞有较好的抑制活性, 其中化合物7e的抗肿瘤活性最好, 其IC50为12.50 μmol/L. 目标化合物为药物筛选提供了一定的参考.

Abstract:

The D-ring C16 position of 16-dehydropregnenolone acetate(16-DPA), a precursor of steroidal drugs, was modified using N-methylindole, and the inexpensive catalytic system of ZrCl4-ethyl acetate was employed to synthesize sixteen (3β-acetyloxy-16α-3'-indolopregnenolone compounds) as well as to synthesize six 3β-hydroxy- 16α-3'-indolone pregnenolone derivatives. The method has the advantages of high yield, good stereoselectivity and substrate adaptability. Twenty-two compounds were tested for antitumor activity in triple-negative breast cancer cells (MDA-MB-231) by thiazolyl blue(MTT) assay. The preliminary test results showed that among the 3β-acetoxy- 16α-3'-indolopregnenolone compounds, compounds 6h and 6i had better cancer inhibitory activities against MDA-MB-231 cancer cells with median inhibition concentration (IC50) of 18.07 and 23.22 μmol/L, respectively, whereas all of compounds 7a—7f had better cancer inhibitory activities against MDA-MB-231 cancer cells, among which compound 7e showed the best antitumor activity with an IC50 of 12.50 μmol/L. These compounds provide some references for drug screening.
