Discovery and structure-activity-relationship study of novel conformationally restricted indane analogues for mutant isocitric dehydrogenase 1 (IDH1) inhibitors
The discovery and optimization of various of indane amides as mutant IDH1 inhibitors via structure-based rational design were reported. The optimal compounds demonstrated both potent inhibition in IDH1R132H enzymatic activity and 2HG production in IDH1 mutant HT1080 cell line, favorable PK properties and great selectivity against IDH1wt and IDH2R140Q.

A Bio-catalyzed N-formylation reaction of different amines has been developed using ethyl formate as formylatingagent. This protocol provides a facile and convenient strategy featuring mild reaction condition, high efficacy,...
ZrIV ions decreases the amount of surface acidic sites, in particular, medium–strong acidic sites and promotes the formation of ˙OOH radicals. Isotopic tracing experiments confirmed that all the carbon atoms in the carbonyl group of formamide products are indeed from glycerol derivatives.

以甘油衍生物(1,3-二羟基丙酮、甘油醛和乙醇酸)为羰基源,通过在沸石 5A 负载的铜基催化剂上催化的原位C-C 键裂解,胺的N-甲酰化可持续合成增值甲酰胺. 引入第二金属Zr IV离子可以大大提高Cu/5A催化剂的活性。催化剂表征结果表明,Zr IV的引入离子减少表面酸性位点的数量,特别是中强酸性位点,并促进˙OOH自由基的形成。同位素示踪实验证实,甲酰胺产物羰基中的所有碳原子确实来自甘油衍生物。结合电子顺磁共振 (EPR) 自旋捕获、原位衰减全反射 (ATR)-FTIR 光谱和控制实验表明,苯胺和 DHA 与甲苯胺的反应涉及 GA 和 HCOOH 中间体以及通过˙OH–˙OOH 的˙NHPh 自由基激进中继机制。
Tailoring Active Cu2O/Copper Interface Sites for N‐Formylation of Aliphatic Primary Amines with CO2/H2
N-formylation of aliphaticprimaryamines with CO2/H2 to formamide is achieved with a heterogeneous non-noble metal Cu-based catalyst containing Cu2O/Cu interface sites.
