H-indol-3-yl)butanoic acid 4aaa was designed against BPH and synthesized by two steps of N-alkylation. One-pot protocol towards 4aaa was newly developed. With IL [C6min]Br as solvent, the yield of 4aaa was increased to 75.1 % from 16.0 % and the reaction time was shortened in 1.5 hours from 48 hours. 25 Derivatives structurally based on arylpiperazine and indolyl butyric acid with alkyl linker were
基于两种α的SAR 1 -AR拮抗剂和5α还原酶(5AR)抑制剂,双重作用的药剂4-(1-(4-(4-(2-甲氧基苯基)哌嗪-1-基)丁基针对BPH设计了)-1 H-吲哚-3-基)丁酸4aaa,并通过N-烷基化的两个步骤合成。新开发了针对4aaa的一锅协议。用IL [C 6分钟]溴作为溶剂,收率4AAA从16.0%提高到75.1%,反应时间是1.5小时缩短为48小时。制备了25种基于芳基哌嗪和吲哚基丁酸的具有烷基连接基的衍生物。进一步扩展了该协议,以获取另外14个衍生词,其中O-烷基化参与其中,并应用于生物有效分子DPQ和阿立哌唑的合成。预期地,化合物4AAA表现出α的双重抑制1 -AR和5α还原酶,和exihited针对人类细胞没有明显的细胞毒性。还确定了4aaa的药代动力学特性。
