The present invention is directed to, in part, compounds and compositions useful for preventing and/or treating a neurological disease or disorder, a disease or condition relating to excessive neuronal excitability, and/or a gain-of-function mutation in a gene (e.g., KCNT1). Methods of treating a neurological disease or disorder, a disease or condition relating to excessive neuronal excitability, and/or a gain-of-function mutation in a gene such as KCNT1 are also provided herein.
adopted as the proper support for highly dispersed Pd NPs with well-controlled size distribution. Compared with microporous N-doped active carbon with low N-content, the MCN-supported Pd catalyst shows an enhanced activity in water phase for the selective ring hydrogenation of benzoic acid, benzamide and phenol, in which 11.3 times higher activity in comparison to undoped catalyst is achieved. Wide characterizations
介孔碳氮化物(MCN)是通过乙二胺(EDA)与四氯化碳(CTC)之间的简单聚合反应,采用纳米硬模板法制备的。所得的多氯化萘具有高表面积(166.3 m 2)/ g),平均孔径为9.2 nm和高N含量(最高18.5 wt%)。MCN表面的负电荷和碱性来自其丰富的氮化碳杂环,从而显着提高了表面亲水性和酸性分子的吸附性。此外,MCN可以用作高度分散的Pd NP的适当支持,并且具有良好的尺寸分布控制。与低N含量的微孔N掺杂活性炭相比,MCN负载的Pd催化剂在水相中对苯甲酸,苯甲酰胺和苯酚的选择性环加氢显示出更高的活性,与未掺杂的相比,活性高11.3倍实现催化剂。广泛的特征表明,大孔径,
Pd(II)-catalyzed enantioselective borylation of C(sp3)-H bonds has been realized for the first time using chiral acetyl-protected aminomethyl oxazoline ligands. This reaction is compatible with carbocyclic amides containing α-tertiary as well as α-quaternary carbon centers. The chiral β-borylated amides are useful synthons for the synthesis of chiral β-hydroxylated, β-fluorinated, and β-arylated carboxylic
