to generate a focused library of high‐quality compounds. The versatility of this approach was combined with the feasibility of a phenotypic assay, integrated with early ADME‐tox profiling. Thus, an 18‐membered library was efficiently assembled via Huisgen cycloaddition of phenothiazine, biphenyl, and phenylpiperazine scaffolds. The resulting 18 compounds were then tested against seven parasite strains
疟原虫,利什曼原虫和锥虫引起的原生动物感染spp。对全世界的传染病负担做出重大贡献,导致严重的发病率和死亡率。现有治疗方法的不足要求进行具有成本效益和时间效益的药物开发。为此,我们设想将特权结构的三唑键连接作为有效的药物设计策略,以生成高质量化合物的重点文库。这种方法的多功能性与表型分析的可行性相结合,并与早期的ADME-tox分析相结合。因此,通过吩噻嗪,联苯和苯基哌嗪支架的Huisgen环加成反应,可以有效地组装一个由18个成员组成的文库。然后对所得的18种化合物针对7种寄生虫菌株进行了测试,并针对两种哺乳动物细胞系进行了反筛选。平行地,h评估了ERG和细胞色素P450(CYP)的抑制作用以及线粒体毒性。值得注意的是,10-((1-(3-([[1,1'-联苯] -3-基氧基)丙基)-1 H -1,1,2,3-三唑-5-基)甲基)-10 H-吩噻嗪(7)和10-(3-(1-(3-([[1
