• Targeting the BACE1 Active Site Flap Leads to a Potent Inhibitor That Elicits Robust Brain Aβ Reduction in Rodents
  作者：Yong-Jin Wu、Jason Guernon、Fukang Yang、Lawrence Snyder、Jianliang Shi、Andrea Mcclure、Ramkumar Rajamani、Hyunsoo Park、Alicia Ng、Hal Lewis、ChiehYing Chang、Dan Camac、Jeremy H. Toyn、Michael K. Ahlijanian、Charles F. Albright、John E. Macor、Lorin A. Thompson

  DOI：10.1021/acsmedchemlett.5b00432

  日期：2016.3.10

  By targeting the flap backbone of the BACE1 active site, we discovered 6-dimethylisoxazole-substituted biaryl aminothiazine 18 with 34-fold improved BACE1 inhibitory activity over the lead compound 1. The cocrystal structure of 18 bound to the active site indicated two hydrogen-bond interactions between the dimethylisoxazole and threonine 72 and glutamine 73 of the flap. Incorporation of the dimethylisoxazole substitution onto the related aminothiazine carboxamide series led to pyrazine-carboxamide 26 as a very potent BACE1 inhibitor (IC50 < 1 nM). This compound demonstrated robust brain A beta reduction in rat dose-response studies. Thus, compound 26 may be useful in testing the amyloid hypothesis of Alzheimer's disease.
