SET 域分叉蛋白 1 (SETDB1) 是一种组蛋白赖氨酸甲基转移酶,可促进某些肿瘤抑制基因的沉默,并在许多癌症中过度表达。SETDB1 包含一个独特的串联 tudor 域 (TTD),可识别包含甲基化和乙酰化赖氨酸的组蛋白 H3 序列。从鉴定命中化合物 ( Cpd1 ) 开始,我们通过逐步结构引导优化发现了第一个有效且选择性的小分子 SETDB1-TTD 抑制剂( R , R )-59。( R , R )-59在 ITC 测定中显示 K D值为 0.088±0.045 μM。的高效力([R ,R )-59可以通过( R , R )-59 -TTD 复合物的共晶结构得到很好的解释。( R , R )-59是一种内源性结合剂竞争性抑制剂。证据也证明了它的细胞目标参与。有趣的是,对映异构体( S , S )-59在所有分析中均未显示活性,突出了( R , R )-59作为探索 SETDB1-TTD

of R chains of amides R1C(O)NHR, a fundamental class of synthetic substrates, has not been accomplished to date. Here, the first example of palladium(II)-catalyzed alkynylation of an unactivated gamma C(sp3)–H bond of alkyl amides (cyclic, linear, and amino acids) is reported. The kinetic experiment shows that the rate of the reaction depends on the coupling partners and the amides. Late-stage diversification
