  摘要：

  布鲁顿酪氨酸激酶（Btk）是一种非受体胞质酪氨酸激酶，分别参与B细胞和髓样细胞活化，位于B细胞和Fcγ受体的下游。临床前研究表明，抑制Btk活性可能为类风湿性关节炎和系统性红斑狼疮等自身免疫性疾病提供潜在的治疗方法。在这里，我们公开了目前在临床开发中的有效，选择性和非共价Btk抑制剂的发现和临床前表征。GDC-0853（29）抑制B细胞和髓细胞介导的疾病成分，并在体内表现出剂量依赖性活性炎性关节炎大鼠模型。它在类风湿性关节炎，狼疮和慢性自发性荨麻疹患者的临床前和2期研究中显示出非常有利的安全性，药代动力学（PK）和药效学（PD）概况。根据其效价，选择性，长目标停留时间和非共价抑制模式，29在广泛的免疫学适应症中具有成为同类最佳Btk抑制剂的潜力。

  Asymmetric Synthesis of 2,6-Methylated Piperazines

  摘要：

  The complete series of enantiopure 2,6-methylated piperazines was synthesized utilizing two alternative reactions in the key bond-forming step. The dimethyl enantiomers, (2R,6R)- and (2S,6S)-2,6-dimethylpiperazine (1, 2), were prepared using either a diastereoselective triflate alkylation or a novel intramolecular Mitsunobu reaction to set the required stereochemistry. The monomethyl derivatives, (R)- and (S)-tert-butyl 2-methyl-1-piperazinecarboxylate (3, 4) were also synthesized employing the Mitsunobu cyclization strategy while the trimethyl compounds, (R)- and (S)-2,2,6-trimethylpiperazine (5, 6) were prepared using an enantiospecific triflate alkylation as the principal reaction. These methods represent efficient, general strategies for preparing a variety of 2,6-methylated piperazines for which the absolute stereochemistry can be readily controlled.
