  Design, Synthesis, and Pharmacological Evaluation of Fused β-Homophenylalanine Derivatives as Potent DPP-4 Inhibitors

  摘要：

  Dipeptidyl peptidase-4 (DPP-4) inhibitors are accepted as a favorable class of agents for the treatment of type 2 diabetes. Herein, a series of fused beta-homophenylalanine derivatives as novel DPP-4 inhibitors were designed, synthesized, and evaluated for their inhibitory activities against DPP-4. Most of them displayed excellent DPP-4 inhibitory activities and good selectivity. Among them, 9aa, 18a, and 18m also showed good efficacy in an oral glucose tolerance test (OGTT) in ICR mice. Moreover, when dosed 8 h prior to glucose challenge, 18m showed significantly greater potency than sitagliptin. It thus provides potential candidates for the further development into potent drugs targeting DPP-4.

  连续多相流硝化和低温流甲酰化：实现医药中间体的工艺开发和制造

  摘要：

  制造 API 和医药中间体需要开发可扩展、安全且环保的工艺。具有高放热性或其他性质危险的反应，以及涉及形成不稳定中间体的反应，都可以从连续加工中受益。由于该技术在低反应体积下运行的固有能力、促进改进的温度控制和安全地适应更高的压力，该技术已被整个制药行业广泛采用。两个这样的工业相关例子是芳族硝化和区域选择性芳环金属化，然后用亲电子试剂捕获。在批处理中进行时，这两种反应类别通常都面临放大的挑战。硝化反应通常具有多相，与大量放热相关的混合敏感反应，可导致形成潜在危险的过硝化副产物。同样，芳环的金属化反应通常需要低温条件，难以大规模实现。在这项研究中，对混合限制的固-液-液 (S-L-L) 硝化反应进行了评估，以了解传输现象。Hatta 数的确定和叶轮功率对动力学的影响使设计出安全、可扩展、高产且稳健的连续搅拌罐 (CSTR) 流动工艺成为可能。对关键甲酰化反应参数的研究导致了第一代管式流动反应器设计，可在中试工厂中处理

  日期：——

  strategy for aromatic trifluoromethylation by converting amino into trifluoromethyl groups via a Sandmeyer-type reaction is reported. The transformation involves diazotization of the aromatic amines with tert-butyl nitrite and hydrochloric acid to form aryldiazonium chlorides, followed by trifluoromethylation with trifluoromethylsilver at low temperature. Various readily available aromatic amines are

  The present invention features formulations of indolinones which compounds are ionizable as free acids or free bases. The formulation is suitable for parenteral or oral administration, wherein the formulation comprises an ionizable substituted indolinone, and a pharmaceutically acceptable carrier therefor. The term “ionizable substituted indolinone” includes pyrrole substituted 2-indolinones which, in addition to being otherwise optionally substituted on both the pyrrole and 2-indolinone portions of the compound, are necessarily substituted on the pyrrole moiety with one or more hydrocarbon chains which themselves are substituted with at least one polar group. The formulations and the compounds themselves are useful for the treatment of protein kinase related disorders as discussed herein.
