A fragment screening approach designed to target specifically the S-adenosyl-l-methionine pocket of catechol O-methyl transferase allowed the identification of structurally related fragments of high ligand efficiency and with activity on the described orthogonal assays. By use of a reliable enzymatic assay together with X-ray crystallography as guidance, a series of fragment modifications revealed an
专门针对儿茶酚O的S-腺苷-1-蛋氨酸口袋设计的片段筛选方法-甲基转移酶可以鉴定具有高配体效率的结构相关片段,并且对所述正交试验具有活性。通过将可靠的酶促测定与X射线晶体学一起用作指导,一系列片段修饰揭示了SAR,经过几次扩展后,可以获得有效的先导化合物。首次报道了非酚类和小的低纳摩尔浓度的强效SAM竞争性COMT抑制剂。这些化合物代表了一系列新的有效COMT抑制剂,这些抑制剂可能会进一步优化用于治疗帕金森氏病,左旋多巴治疗或精神分裂症的辅助药物。
