of 4-Boc-piperazine-1-carboxamidine with 3-(dimethylamino)propenones, deprotection and coupling with the sulfamoylated building block. Target ureidosulfamates 5-31 and 35-42 were evaluated both as STS inhibitors in vitro using a lysate of JEG-3 human placenta choriocarcinoma cell line and in a whole cell assay. SAR conclusions were drawn from both series. In series 35-42 the best inhibitory activity
针对新兴的肿瘤药物靶标类固醇硫酸酯酶(STS)设计了两个基于哌嗪基-脲基单环芳基氨基磺酸盐的抑制剂系列,目前在临床试验中已有有效的类固醇和非类固醇药物。通过使4-羟基芳基胺与苯基氯甲酸酯反应,随后将所得的羟基芳基氨基甲酸酯进行氨磺酰化,并将产物与1-取代的哌嗪偶联,得到4-(哌嗪基羰基)氨基磺酸酯(5-31)。嘧啶基-哌嗪氨基脲氨基磺酸盐(35-42)的合成方法是:将4-Boc-哌嗪-1-羧box的嘧啶闭环与3-(二甲基氨基)丙烯酰胺进行脱保护并与氨磺酰化的结构单元偶联。使用JEG-3人胎盘绒毛膜癌细胞系的裂解物,并在全细胞试验中,将目标脲基氨基磺酸盐5-31和35-42都作为STS抑制剂进行了体外评估。SAR结论是从两个系列中得出的。在35-42系列中,最好的抑制活性与嘧啶环上苯并呋喃基的存在有关。在5-31系列中,最佳的抑制活性是通过在哌嗪子酮4-氮原子上带有4-氯苯基,3,4-二氯苯
