摘要
以取代邻硝基苯甲酸为起始原料,与二氯亚砜反应制得邻硝基苯甲酰氯,再与苯胺在碱性条件下反应制得酰胺衍生物(6a^6d);以醋酸钯为催化剂,6a^6d经NBS溴代制得溴代衍生物(7a^7d);7a^7d依次经N-烷基化反应,还原反应和分子内C—N键环合反应合成了10个新型的1,4-二苯并二氮杂酮类化合物(10a^10j),产率61%~78%,其结构经~1H NMR,13C NMR和HR-MS(ESI)表征。初步体外活性测试结果表明:10a^10j对非小细胞肺癌细胞(A549),人乳腺癌细胞(MDA-MB-231)和宫颈癌细胞(He La)均有抑制作用。其中,10g和10i对A549,10g对MDA-MB-231,10h和10i对He La的抑制率大于50%。
The amide derivatives(6a ~ 6d) were obtained by the reaction of substituted o-nitrobenzoic acids with SOCl2, then reaction with aniline under basic condition. The brominated derivatives(7a ~ 7d) were prepared by NBS-bromination of 6a ~ 61t, using Pd(OAc) 2 as the catalyst. Ten novel 1,4- dibenzodiazepin compounds (10a ~ 10j ) were synthesized by the reaction of N-alkylation, reduction and intramolecular C--N bond cyclization from 7a ~ 7d, respectively. The structures were characterized by ^1H NMR, ^13C NMR and HR-MS (ESI). The preliminary in vitro bio-activity tests showed that 10a ~ 10j had certain inhibitory effects on non-small cell lung cancer cell( A549 ), human breast cancer cell( MDA-MB-231 ) and cervical cancer cell(HeLa). Among them, the inhibition rates of 10g and 10i on A549, 10g and 10h on MDA-MB-231 and 10i on HeLa were above 50%.
