the chalcone analogs 7 and 8 were prepared from treatment of methyl 3 - oxo-3 H -benzocoumarin-2-carboxylate ( 4 ) with aryl aldehydes. Treatment of 7 and 8 with three anti-inflammatory drugs, flurbiprofen, ketoprofen and ibuprofen, in the presence of POCl 3 /DMAP gave the ester analogs 9 – 12 . Analogously, treatment of ethyl 3 - oxo-3 H -benzocoumarin-2-carboxylate ( 15 ), prepared previously from
新的前列腺癌蛋白受体细胞色素P450 17A1抑制剂的开发提供了产生效力增强结构的可能性。为此,查尔酮类似物7和8是通过用芳基醛处理3-氧代-3 H-苯并香豆素-2-羧酸甲酯(4)制备的。在POCl 3 / DMAP存在下,用三种抗炎药氟比洛芬,酮洛芬和布洛芬治疗7和8,得到酯类似物9-12。类似地,用各种芳基胺处理先前由2-羟基-1-萘醛(13)和丙二酸二甲酯(14)制得的3-氧代-3 H-苯并香豆素-2-羧酸乙酯(15),用各种芳基胺:4-溴苯胺,2-在叔丁醇钾存在下,氨基-6-甲基吡啶,氨基-安替比林和2-氨基-5-硝基噻唑产生了苯并香豆素-3-芳基酰胺类似物。通过MTT分析评估了9-12和16-19的体外细胞毒性对人前列腺癌细胞系(PC-3)和正常人肝上皮细胞(WRL-68)的毒性。化合物10和17是针对PC-3细胞系列中最具活性的细胞毒性剂,IC 50值为71.35和78.25μgmL
