  Lead Optimization and Modulation of hERG Activity in a Series of Aminooxazoline Xanthene β-Site Amyloid Precursor Protein Cleaving Enzyme (BACE1) Inhibitors

  摘要：

  The optimization of a series of aminooxazoline xanthene inhibitors of beta-site amyloid precursor protein cleaving enzyme 1 (BACE1) is described. An early lead compound showed robust A beta lowering activity in a rat pharmacodynamic model, but advancement was precluded by a low therapeutic window to QTc prolongation in cardiovascular models consistent with in vitro activity on the hERG ion channel. While the introduction of polar groups was effective in reducing hERG binding affinity, this came at the expense of higher than desired Pgp-mediated efflux. A balance of low Pgp efflux and hERG activity was achieved by lowering the polar surface area of the P3 substituent while retaining polarity in the P2' side chain. The introduction of a fluorine in position 4 of the xanthene ring improved BACE1 potency (5-10-fold). The combination of these optimized fragments resulted in identification of compound 40, which showed robust A beta reduction in a rat pharmacodynamic model (78% A beta reduction in CSF at 10 mg/kg po) and also showed acceptable cardiovascular safety in vivo.
