  Diazine Indole Acetic Acids as Potent, Selective, and Orally Bioavailable Antagonists of Chemoattractant Receptor Homologous Molecule Expressed on Th2 Cells (CRTH2) for the Treatment of Allergic Inflammatory Diseases

  摘要：

  New classes of CRTH2 antagonists, the pyridazine linker containing indole acetic acids, are described. The initial hit 1 had good potency but poor permeability, metabolic stability, and PK. Initial optimization led to compounds of type 2 with low oxidative metabolism but poor oral bioavailability. Poor permeability was identified as a liability for these compounds. Addition of a linker between the indole and diazine moieties afforded a series with good potency, low rates of metabolism, moderate permeability, and good oral bioavailability in rodents, 32 was identified as the development track candidate. It was potent in cell based, binding, and whole blood assays and exhibited good PK profile. It was efficacious in mouse models of contact hypersensitivity (1 mg/kg b.i.d.) and house dust (20 mg/kg q.d.) when dosed orally. In sheep asthma, administration at 1 mg/kg iv completely blocked the LAR and AHR and attenuated the EAR phase.

  A method has been devised for the microwave-assisted, continuous-flow preparation of indole alkaloids by a two-step aryl amination/cross-coupling sequence of bromoalkenes and 2-bromoanilines. This process requires both the presence of a metal-lined flow tube (a 1180 micron capillary) and the Pd PEPPSI-IPr catalyst; without either, the catalyst or the film, there is zero turnover of this catalytic process

  已经设计了一种通过溴代烯烃和2-溴苯胺的两步芳基胺化/交叉偶联序列来微波辅助，连续流制备吲哚生物碱的方法。该过程既需要金属衬里的流管（1180微米毛细管），也需要Pd PEPPSI-IPr催化剂。如果没有催化剂或膜，则该催化过程的周转率为零。已显示银膜可提供一定的转化率（48％至62％），但是通过使用高度多孔的钯膜，可以在各种溴代烯烃和溴代苯胺上获得最佳结果（定量）。考虑了Pd膜的可能作用，以及催化剂和膜之间的相互作用。
